A water-based, silicone-free polymer preservation for engines, ancillaries, housings and rubber hoses that forms a permanently elastic protective film up to 250 °C and carries the Daimler factory approval (GOTIS P 00.16 – 02.0). Not suitable for drive belts, brake components, body paint or open intake areas.\u003c\/em\u003e\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003cp id=\"speakable-definition\"\u003e\u003cstrong\u003eKoch-Chemie Motorplast „Mp“\u003c\/strong\u003e is an engine preserver from Koch-Chemie that protects plastic covers, rubber hoses and ancillaries in the engine bay against corrosion, road salt and UV stress with a permanently elastic polymer film. You spray it on as a pump mist over the pre-cleaned, still-wet engine bay, where it pushes out the residual water and cross-links after 6 to 8 hours into a dirt-repellent, wafer-thin layer. Unlike classic engine-shine sprays, Motorplast skips propellants and silicone, which is what clears it for use in body shops (no painter's fisheyes) and on Mercedes-Maybach models (official factory approval).\u003c\/p\u003e\n\n\u003cp\u003eThe look stays deliberately satin-matt rather than high-gloss — the surface keeps its original character, the protection is physically there without the engine looking like it has just been oiled up. After the treatment the bay looks clean, not „greased“.

The approval checks compatibility on EPDM coolant hoses and PA, PP and ABS covers under 90–110 °C sustained load — that's why brand workshops reach for this product instead of any random engine-shine spray.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSilicone-free and propellant-free.\u003c\/strong\u003e The water-based polymer carrier holds no volatile silicone oils (critical near paintwork — think fisheyes) and no aerosol (no butane\/propane propellants).

In the 5 L pro canister the price per litre drops noticeably — that version is built for detailing shops, fleet care and high-mileage households. 20 and 200 litre containers exist for industrial customers.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003chr\u003e\n\n\u003cblockquote class=\"praxistipp\"\u003e\n  \u003cp\u003e\u003cstrong\u003eDetailing1's tip from the shop:\u003c\/strong\u003e The most common mistake with Motorplast isn't too little, it's too much. Lay down puddles instead of a fine mist and you stretch the drying time well past the usual 6 to 8 hours, the polymer cures unevenly and leaves milky edges or tacky spots. The clean routine: let the engine cool to hand-warm, pre-clean with \u003ca href=\"\/en\/products\/koch-chemie-green-star-gs-universalreiniger\"\u003eGreen Star\u003c\/a\u003e at 1:10, rinse off with a soft water jet, mist Motorplast thinly into the still-wet bay, close the bonnet and let it sit overnight. Tap any leftover pools the next morning with a dry microfibre cloth. It's self-levelling — no working in with a pad needed.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eSpray it on wet. Bonnet shut. Dry overnight.\u003c\/h3\u003e\n\n\u003cp\u003eYou spray Motorplast onto the pre-cleaned, still-wet engine bay because the residual water carries the polymers right into the tight gaps before the product itself pushes it back out. That's pro technique straight from the Daimler factory-norm test, not a marketing slogan.\u003c\/p\u003e\n\n\u003cp\u003eBefore you apply, let the engine cool down — hand-warm is ideal, boiling hot is not. On a block sitting at 130 °C oil temperature after a motorway run, the water-glycol-ether mix flashes off instantly and burns the polymers into the plastic as streaks. The officially approved heat window is 250 °C component temperature — that's for the cured film, not for the moment you apply it.\u003c\/p\u003e\n\n\u003cp\u003eFor a mid-size car, reckon on 50 to 200 ml. Work sparingly from about 20 cm away with the spray head and go systematically from back to front — valve cover, fuse box, then intake manifold, then the visible hoses and seals. You can reach awkward spots with a Cyclone or Tornador gun at 4 to 6 bar; in the home garage the supplied spray head does the job. Keep the mist away from open intake tracts and mass airflow sensors — those hot-wire sensors react badly to polymer coatings.\u003c\/p\u003e\n\n\u003cp\u003eOnce it's on, close the bonnet and let it sit 6 to 8 hours, ideally overnight. Day-one test: check the next morning whether any pools or drips are still holding. If so, tap them with a dry microfibre cloth — don't rub. The film is self-levelling and needs no mechanical spreading.\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-motorplast-mp-motorkonservierung_anwendung.png?v=1777464474\" alt=\"Koch-Chemie Motorplast Mp being sprayed onto a wet engine bay Detailing1\" loading=\"lazy\" style=\"width:100%;height:auto;border-radius:4px;\"\u003e\u003c\/p\u003e\n\n\u003ch3\u003ePlastic, rubber, ancillaries. Never the drive belt.\u003c\/h3\u003e\n\n\u003cp\u003eMotorplast is approved for the typical engine-bay materials: PA, PP and ABS plastic covers, EPDM rubber hoses, seals and metal ancillaries in aluminium or steel. On these substrates the permanently elastic polymer film forms, holding off dirt build-up by months and slowing road-salt corrosion.\u003c\/p\u003e\n\n\u003cp\u003eThe hard limits are friction- and safety-critical. Drive belts, V-belts and pulleys are off-limits — the polymer layer cuts the grip friction, the belt slips and worst case the alternator drops out. For the same reason, keep it off brake components, brake disc faces and the pedals. On body paint, overspray leaves streaks and is pointless there anyway — Motorplast is no paint sealant. Any mist that lands on an inner wing or bumper edge, wipe it off straight away with a damp microfibre.\u003c\/p\u003e\n\n\u003cp\u003eIf too much product did end up in the bay and milky streaks have formed, a stripping routine with an alkaline cleaner sorts it: spray \u003ca href=\"\/en\/products\/koch-chemie-green-star-gs-universalreiniger\"\u003eGreen Star\u003c\/a\u003e on generously at 1:10, foam it up with a soft detailing brush, rinse off. The cross-linked polymers break down under the APC and the film comes off without residue. After that you can lay on a second, thinner coat of Motorplast.\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-motorplast-mp-motorkonservierung_detail.png?v=1777464492\" alt=\"Koch-Chemie Motorplast Mp permanently elastic protective film on a plastic cover\" loading=\"lazy\" style=\"width:100%;height:auto;border-radius:4px;\"\u003e\u003c\/p\u003e\n\n\u003ch3\u003eSpring and autumn. Twice a year is plenty.\u003c\/h3\u003e\n\n\u003cp\u003eThe typical rhythm for Motorplast is twice a year — once in spring after the salt season and once in autumn before winter sets in. In between, dusting the plastic covers with a microfibre cloth is enough. Detailing shops slot the product into their winter-check packages, because 5 minutes of work buys 6 months of corrosion protection.\u003c\/p\u003e\n\n\u003cp\u003eThe 500 ml spray bottle is the right call for a single car or for hobbyists getting seasonal vehicles like convertibles or classics ready for spring. Per treatment 50 to 100 ml — so the bottle carries you across several seasonal cycles. For multi-car households or commercial detailers the 5 litre canister pays off: noticeably lower price per litre, just decant it into a separate \u003ca href=\"\/en\/collections\/koch-chemie\"\u003eKoch-Chemie\u003c\/a\u003e cylinder bottle with a spray head. 20 and 200 litre containers are pure industrial variants for workshop groups and OEM supplier chains.\u003c\/p\u003e\n\n\u003cp\u003eStorage is fussier than with many other detailing products: Motorplast keeps at +5 °C to +25 °C, frost-free and out of the sun. Frost breaks down the polymer emulsion and the product won't spray cleanly afterwards. It's fine in the garage or the stockroom — just don't let it overwinter in the boot.\u003c\/p\u003e\n\n\u003cp\u003eApply Motorplast properly once — cold engine bay, wet pre-clean, thin mist, bonnet shut overnight — and you get an engine bay that looks the same after winter as it did before. That's the Detailing1 standard: not shine in the shop window, but an engine that still runs like new after three winters. For full seasonal care you pair Motorplast with \u003ca href=\"\/en\/products\/koch-chemie-green-star-gs-universalreiniger\"\u003eGreen Star\u003c\/a\u003e as the pre-cleaner — that's the complete engine-bay workflow in under 30 minutes per car.\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-motorplast-mp-motorkonservierung_lineup.png?v=1777464511\" alt=\"Koch-Chemie Motorplast Mp 500ml spray bottle and 5 litre canister Detailing1\" loading=\"lazy\" style=\"width:100%;height:auto;border-radius:4px;\"\u003e\u003c\/p\u003e\n","brand":"Koch-Chemie","offers":[{"title":"500ml","offer_id":48498577211727,"sku":"D1-KCX-236500","price":9.99,"currency_code":"EUR","in_stock":true},{"title":"2x500ml","offer_id":49763373973839,"sku":"D1-KCX-236500_2","price":19.58,"currency_code":"EUR","in_stock":true},{"title":"3x500ml","offer_id":49763374006607,"sku":"D1-KCX-236500_3","price":29.07,"currency_code":"EUR","in_stock":true},{"title":"5 liters","offer_id":48498577277263,"sku":"D1-KCX-236005","price":65.49,"currency_code":"EUR","in_stock":true},{"title":"20 liters","offer_id":49763374039375,"sku":"D1-KCX-236020","price":244.49,"currency_code":"EUR","in_stock":true},{"title":"200 liters","offer_id":49763374072143,"sku":"D1-KCX-236200","price":2602.99,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/koch-chemie-motorplast-motorkonservierung.jpg?v=1710780165"},{"product_id":"koch-chemie-glas-star-gla-glasreiniger-konzentrat","title":"Glas Star \"Gla\" Glass Cleaner Concentrate","description":"\u003ch2 id=\"speakable-headline\"\u003eStreak-free glass with Koch-Chemie Glas Star\u003c\/h2\u003e\n\n\u003cblockquote id=\"speakable-summary\"\u003e\n  \u003cp\u003e\u003cem\u003eWhat is Koch-Chemie Glas Star?

Our day-to-day mix sits at 60% concentrate to 40% distilled water for medium soiling. The official 1:3 is for clean refresh passes, not for the heavy stuff.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eNeat or diluted: dial in the mix\u003c\/h3\u003e\n\u003cp\u003eYou mix Glas Star into a \u003ca href=\"\/en\/products\/koch-chemie-spruehkopf-spruehflasche-set\"\u003espray bottle with a Canyon CHS-3AN spray head\u003c\/a\u003e — the concentrate bottle itself ships without a spray head because it's a refill format. For standard interior work, 250 ml of concentrate into 750 ml of distilled water gives you a liter of spray. That 1:3 ratio is Koch-Chemie's official spec and handles light to medium soiling without drama.\u003c\/p\u003e\n\n\u003cp\u003eOn heavily-soiled glass — nicotine film, baked-on bugs on the inside of the windshield, old adhesive or sticker residue — you go neat. Spray straight onto the glass towel, not the panel, so you don't fling drops onto the dashboard or door card. Neat is also the move for the inside of the windshield, where outgassed plastics build a paper-thin film that diluted mix only half-dissolves. You spot that layer by the streaky glare in backlight even after you've just cleaned.\u003c\/p\u003e\n\n\u003cp\u003eDilution mistake we see often: concentrate first into the empty bottle, then water — that order builds a foam crown you'll be rinsing for minutes. Reverse it: water first, then drop the concentrate in and swirl slowly, don't shake.

Sun in a clear spray bottle eats the shine additives noticeably after about eight weeks. An HDPE bottle from the spray-bottle set holds up far better than any recycled clear bottle out of the drugstore aisle.\u003c\/p\u003e\n\n\u003cp\u003eLabel every bottle with the ratio and the date. Sounds petty, saves frustration: if three months down the line the result gets worse, you know straight away whether it's the towel, the ratio, or an aged mix.

Not tint film.\u003c\/h3\u003e\n\u003cp\u003eThe alcohol content pulls silicone, grease, wax residue, and light overspray in one wipe — the bread-and-butter of most interior glass work. It also cuts baked-on bugs on the outside of the windshield if you pre-soak with water first. So Glas Star handles both inside and outside glass — most interior-only cleaners can't say the same.\u003c\/p\u003e\n\n\u003cp\u003eOn the inside of the rear screen, most cleaners struggle because the embedded heating elements act like edges. Glas Star runs smoothly over the wires thanks to the glide aid and won't streak there — as long as you wipe in one direction with a \u003ca href=\"\/en\/products\/koch-chemie-pro-glass-towel-230gsm-mikrofaser-glastuch\"\u003eglass-specific microfibre\u003c\/a\u003e, not in circles.

Cut to at least 1:3 and keep clear of the edges. On anti-fog coated interior glass (some OEM windshields from 2020 onward), neat Glas Star can streak — patch-test on a 5×5 cm spot first. For matte surfaces, bare wood, or acrylic (convertible rear windows) it's out — for those the much milder \u003ca href=\"\/en\/products\/tuga-chemie-tugalin-glas-teufel-glasreiniger\"\u003eTugalin Glas-Teufel\u003c\/a\u003e sits in the range as a ready-to-use option.\u003c\/p\u003e\n\n\u003cp\u003eThe Daimler approval on the concentrate means this: the product has been signed off in the manufacturer's materials lab for use on the glass and plastic trims fitted to all current Mercedes models.

With fresh air on, the blower pulls dust out of the engine bay onto the glass while you're wiping — streaks are basically guaranteed.\u003c\/p\u003e\n\n\u003cp\u003ePros also flip the sun visors down, because an astonishing amount of spray ends up on them.

Day-to-day you save 5–10 minutes of drying per wash, because all you do is wipe the leftover water off edges and mirrors. Koch-Chemie calls this \"Micro-Bead-free Drying\" — the water forms no standing droplets, it runs off in sheets.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProtection beyond the paint.\u003c\/strong\u003e The Pw preserves more than just paint — it also seals rubber and plastic trim as well as convertible tops.

Spray the concentrate on neat and you risk streaks on dark paint, because the active concentration is too high. The right dilution: 30 ml per 1 litre of water.

That sets it apart from hard waxes, which need 20–30 minutes of working time per car, or ceramic coatings, which take paint correction as prep.\u003c\/p\u003e\n\n\u003cp\u003eMix 30 ml of concentrate into 1 litre of water — best in a foam sprayer like the Gloria FM10 or a pump-up spray bottle. Spray the solution evenly onto the wet, freshly washed car. Start at the roof and work your way down: bonnet, wings, doors, bumpers.\u003c\/p\u003e\n\n\u003cp\u003eThe product works straight away — you can see from the changed surface tension that the reactive components are keying in. The 1:33 dilution sounds light, but it's chosen on purpose: Koch-Chemie designed the Pw for car-wash use, where only 13–19 ml goes on undiluted per car.\u003c\/p\u003e\n\n\u003cp\u003eAfter 2–3 minutes of dwell time, rinse everything off with the pressure washer, top to bottom. Thoroughly, with plenty of water. This is the critical step: rinse too little and you get white wax residue on dark paint.\u003c\/p\u003e\n\n\u003cp\u003eThen wipe the leftover water off mirrors, door edges and the fuel cap with a drying towel. The rest runs off on its own thanks to the sheeting. A common mistake we see day-to-day: some people then spray a finish spray on top. That's counterproductive, because the spray partly lifts the fresh wax layer back off.\u003c\/p\u003e\n\n\u003cp\u003eKoch-Chemie offers its own spray bottle with a printed dilution scale — handy, but not a must. Any standard pump sprayer or foam sprayer does the job.

It doesn't fill scratches.\u003c\/h3\u003e\n\u003cp\u003eThe Koch-Chemie Protector Wax gives you a deep, wet high gloss — especially visible on dark paint after the third or fourth application. The gloss build is cumulative: every layer cross-links with the one before.\u003c\/p\u003e\n\n\u003cp\u003eDay-to-day, a single application lasts 3–5 weeks. That sounds short next to ceramic coatings with 12+ months of durability — but it's a different concept. The Pw is a care routine, not a one-off shield.\u003c\/p\u003e\n\n\u003cp\u003eIf you wash every 1–2 weeks and apply the Pw each time, you've got lasting protection that beats a neglected one-off sealant. Detailers in the community report that after a week of bad weather and 1,000 kilometres their car was cleaner than after a hand wash without the Pw.\u003c\/p\u003e\n\n\u003cp\u003eThat comes down to the Lotus effect: dirt particles cling less to the hydrophobic surface and get partly washed off by the next rain. This self-cleaning behaviour is called sheeting — the water forms no standing droplets (beading), it runs off as a closed film and carries dirt particles with it. The Pw gives you both: beading across the flat panels and sheeting at the edges.\u003c\/p\u003e\n\n\u003cp\u003eWhat the Protector Wax can't do: fill scratches or restore oxidised paint. Fine swirls are visually masked by the gloss build, but not chemically bonded. If you've got visible scratches, you need a polish first before the wax makes sense. The order: wash, polish, then seal with the Pw — not the other way round.\u003c\/p\u003e\n\n\u003cp\u003eOn ceramic-coated cars the Pw is redundant — the coating already has better durability and hydrophobicity. Here the \u003ca href=\"\/en\/products\/koch-chemie-spray-sealant-s0-02-spruehversiegelung\"\u003eKoch-Chemie Spray Sealant S0.02\u003c\/a\u003e is the better pick as a coating top-up.

No prep, no cure time, no re-buffing. Spray on, rinse off, done. If you want your paint protected between washes without booking in a dedicated sealing day, the Pw is the right tool.\u003c\/p\u003e\n\n\u003cp\u003eThe Pw makes particular sense if you wash weekly or every other week and don't want to plan in a separate sealing step. For self-service-bay users it slots straight into the existing wash routine. With a pleasant cherry scent instead of the typical chemical smell of many wax products, you can use it in an underground car park or with the garage door shut, too. It works on glass as well — the windscreen picks up a light water-repellent effect from the Pw that improves visibility in the rain.\u003c\/p\u003e\n\n\u003cp\u003eThe Protector Wax is less suited to you if you only wash every 4–8 weeks. The protection layer won't build then and you're better off with the \u003ca href=\"\/en\/products\/koch-chemie-hydro-foam-sealant-s0-03-nassversiegelung-konzentrat\"\u003eKoch-Chemie Hydro Foam Sealant S0.03\u003c\/a\u003e. As a foam sealant in the pressure-washer workflow, the Hydro Foam Sealant gives longer durability per single application. For an overview of all the options, take a look at our \u003ca href=\"\/en\/collections\/spruehversiegelung\"\u003espray sealant\u003c\/a\u003e category.\u003c\/p\u003e\n\n\u003cp\u003eWith the 1-litre bottle and 30 ml per wash you get around 33 applications — that's half a year at weekly use. The 10-litre version pays off for businesses and fleets running several cars. The 20-litre version is meant for car-wash operators and commercial detailers who dose the Pw by machine.\u003c\/p\u003e\n\n\u003cp\u003eStore frost-free, and never keep diluted product — always mix it fresh. The reactive components lose their cross-linking ability once diluted. The concentrate itself keeps indefinitely when stored correctly between 5 and 30 °C. A tip for winter: the Pw contains no mineral oil hydrocarbons, which makes it kinder to the environment than many solvent-based wax products — relevant if you wash at a self-service bay with biological waste-water treatment.\u003c\/p\u003e\n\n\u003cp\u003eThe full wash workflow with the Protector Wax looks like this: pre-wash with snow foam, contact wash with car shampoo using the two-bucket method, rinse clear, spray the Pw on and rinse off. Under 30 minutes for the whole car, sealing included. No separate step, no swapping tools, no extra drying time thanks to the sheeting effect. That makes the Protector Wax the logical finish to any hand wash — from the occasional washer to the fleet operator.\u003c\/p\u003e\n\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/koch-chemie-protector-wax-pw-konservierungswachs-nassversiegelung-lineup.jpg?v=1776077468\" alt=\"Koch-Chemie Protector Wax Pw 1 litre bottle and 10 litre canister\" loading=\"lazy\" width=\"2000\" height=\"1493\"\u003e","brand":"Koch-Chemie","offers":[{"title":"1000 ml \/ 1 liter","offer_id":48489158148431,"sku":"D1-KCX-319001","price":29.49,"currency_code":"EUR","in_stock":true},{"title":"2x 1000ml","offer_id":49764590747983,"sku":"D1-KCX-319001_2","price":62.7,"currency_code":"EUR","in_stock":true},{"title":"3x 1000ml","offer_id":49764591010127,"sku":"D1-KCX-319001_3","price":93.09,"currency_code":"EUR","in_stock":true},{"title":"10 liters","offer_id":48762521289039,"sku":"D1-KCX-319010","price":147.49,"currency_code":"EUR","in_stock":true},{"title":"20 liters","offer_id":49673116418383,"sku":"D1-KCX-319020","price":279.49,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/koch-chemie-protector-wax-pw-konservierungswachs-nassversiegelung.png?v=1721902170"},{"product_id":"koch-chemie-alkali-wheel-cleaner-awh-felgenreiniger-alkalisch","title":"Alkali Wheel Cleaner \"Awh\" Wheel Cleaner (alkaline)","description":"\u003ch2 id=\"speakable-headline\"\u003eWith the Awh you pull brake dust and tyre-rubber bloom off in one pass\u003c\/h2\u003e\n\n\u003cblockquote id=\"speakable-summary\"\u003e\n  \u003cp\u003e\u003cem\u003eThe Koch-Chemie Alkali Wheel Cleaner \"Awh\" is a highly alkaline wheel cleaner (pH 14) for workshops, detailers and fleets.

Awh alone or Mwc alone won't strip the same wheel as thoroughly, because the two go after two different layers of grime.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003ePre-wet, dilute 1:5, three minutes, rinse\u003c\/h3\u003e\n\n\u003cp\u003eThe wheel has to be cold and fully wetted with water before the first spray. Hot brake discs radiate well past 200 °C — if the cleaner hits that heat, the water in the dilution flashes off in seconds and you're left with highly concentrated potassium hydroxide standing on the paint, eating into the clear coat. Wait at least 15 minutes after parking up and wet it down generously.\u003c\/p\u003e\n\n\u003cp\u003eThe dilution follows the level of dirt: 1:10 is enough for weekly upkeep, 1:5 is the all-round figure for normal brake dust after two to four weeks of driving, 1:2 stays reserved for the extreme crusts on workshop vehicles. A pump sprayer with a foam nozzle like the \u003ca href=\"\/en\/products\/koch-chemie-foamer-bottle-schaumspender-150ml\"\u003eKoch-Chemie Foamer Bottle\u003c\/a\u003e or an iK Foam sprayer lays the solution down as a sticky wet foam that clings to the barrel and doesn't run off. On rougher wheels you can go over it with a soft wheel brush after 30 seconds — spread it, don't scrub.\u003c\/p\u003e\n\n\u003cp\u003eDwell time 1 to 3 minutes, 5 minutes max at the weakest dilution. Longer does nothing: Awh isn't about reaction time, it's about chemistry. Leave it on too long and all you risk is drying-in, and dry edges on the clear coat are the result. If a spot isn't clean, top up the dose — don't let it dwell longer.\u003c\/p\u003e\n\n\u003cp\u003eFinish with a strong pressure jet top to bottom. Rinse the barrel and the spoke edges in a controlled way until no foamy veil runs off any more. Cold rinse water is a must: warm water speeds up drying-in inside the barrel, and a leftover cleaner film later pulls into the clear coat as a run mark. On the tyre sidewalls you can put the Awh straight to use — it lifts the brown antioxidant bloom (tyre-rubber blooming) at the same time and saves you the separate tyre cleaner.\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-alkali-wheel-cleaner-awh-felgenreiniger-alkalisch_anwendung.png?v=1778768219\" alt=\"Daniel spraying Koch-Chemie Alkali Wheel Cleaner Awh 1:5 from the iK Foam Pro 2 Alk onto the wheel barrel\" loading=\"lazy\" style=\"width:100%;height:auto;border-radius:4px;\"\u003e\u003c\/p\u003e\n\n\u003ch3\u003eSteel and painted aluminium yes, polished wheels no\u003c\/h3\u003e\n\n\u003cp\u003eAwh is cleared for standard steel wheels and alkali-resistant painted or powder-coated OEM aluminium wheels. As long as an intact clear coat protects the aluminium, the wheel behaves like perfectly normal paint and takes the cleaner with no trouble. That covers the vast bulk of the cars that sit on the lift at workshops and detailers every day — from lease returns to company cars.\u003c\/p\u003e\n\n\u003cp\u003eWhat Awh won't tolerate: raw aluminium, high-gloss polished aluminium, anodised wheels, magnesium wheels, uncoated forged wheels and chrome. On these surfaces the potassium hydroxide reacts with the metal in seconds. It oxidises the surface and leaves a milky, deeply etched patch — what's known as alkali burn.\u003c\/p\u003e\n\n\u003cp\u003eThis damage can't be washed off. The wheel is only saveable with hours of machine polishing at a specialist shop, and that runs into several hundred euros fast. In plain terms: on expensive multi-piece BBS RS wheels, on Porsche Fuchs wheels, on uncoated OZ forged wheels and on chrome lips, the sprayer stays in your hand. If you're not sure whether the wheel is anodised or painted, ask the manufacturer or test on an inconspicuous spot.\u003c\/p\u003e\n\n\u003cp\u003eFor exactly these sensitive wheel types, the pH-neutral \u003ca href=\"\/en\/products\/koch-chemie-magic-wheel-cleaner-mwc-felgenreiniger\"\u003eMagic Wheel Cleaner \"Mwc\"\u003c\/a\u003e or the reactive \u003ca href=\"\/en\/products\/koch-chemie-reactive-wheel-cleaner-felgenreiniger-750ml\"\u003eReactive Wheel Cleaner\u003c\/a\u003e is the right call. They bind the iron particles chemically and don't attack the aluminium.\u003c\/p\u003e\n\n\u003cp\u003eRule of thumb for switching between wheel types: Awh for steel and painted OEM alloy. Mwc or Reactive Wheel Cleaner for polished, anodised or chrome. If you need maximum bite on very robust steel wheels, reach for the acidic \u003ca href=\"\/en\/products\/koch-chemie-triple-acid-star-ta-felgenreiniger\"\u003eTriple Acid Star \"Ta\"\u003c\/a\u003e. That's a different category with its own risks, but the right answer for neglected winter wheels with no aluminium in the mix.\u003c\/p\u003e\n\n\u003cp\u003eOne more mix-up we'll clear up right here: at Koch-Chemie the abbreviation \"Awc\" doesn't stand for an acidic wheel cleaner, it stands for the Allround Window Cleaner — a glass cleaner, in other words.

That makes it clear who the product is for: anyone washing several cars a day or a whole fleet.\u003c\/p\u003e\n\n\u003cp\u003eThose are workshops, professional detailers, fleets and wash bays with an oil separator. A 1-litre spray bottle for the home garage is something Koch-Chemie deliberately doesn't carry under this code. The cleaner is built for continuous use and dilution logic, not for the weekend detailer with one car in the underground car park.\u003c\/p\u003e\n\n\u003cp\u003eOn consumption the dilution in a foam sprayer pays for itself directly. At the standard 1:5 dilution, the 5-litre canister yields 30 litres of working solution. At around 200 ml of ready-to-use mix per vehicle, one 5-litre canister covers about 150 full cars.\u003c\/p\u003e\n\n\u003cp\u003eThe 20-litre canister only pays off with heavy day-in-day-out work. Detailers with high daily throughput, rental-car fleet cleaning, hauliers running their own fleet care. For the keen hobby detailer, Awh is usually overkill. Here \u003ca href=\"\/en\/collections\/felgenreiniger\"\u003epH-neutral wheel cleaners\u003c\/a\u003e like Mwc, Reactive Wheel Cleaner or Sonax FelgenBeast are the more honest choice.\u003c\/p\u003e\n\n\u003cp\u003eThe one trick the manufacturer doesn't push hard: Awh doubles as a first-rate tyre cleaner.

We often get messages like \"the glass cleaner leaves streaks\". Usually the wiping happened on a warm pane in the sun, where the film flashes off before the cloth lifts it. Work on a cold pane in the shade and go by the two-cloth rule: lift the dirt with 1 damp cloth, then buff dry in straight passes with a dry glass cloth. More product doesn't clean better, it tends to leave edges.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eSpray it on neat, pull it off streak-free with two cloths\u003c\/h3\u003e\n\u003cp\u003eYou spray the Glass Cleaner \"Gc\" on neat from 20 to 30 cm onto the cold, shaded pane and pull it off with a dry microfibre glass cloth in straight passes. That way no film of water is left standing to flash off.\u003c\/p\u003e\n\u003cp\u003eOutside, the cleaner lifts bug splatter, pollen and the greasy road film. With a baked-on bug front, let the cleaner soak for about 30 seconds and only then pull it off, rather than scrubbing harder. That goes easy on the glass and on the wiper blades.\u003c\/p\u003e\n\u003cp\u003eInside, it's about the greasy film off-gassing from the dash and about nicotine. If you want to \u003cem\u003eclean your car windows from the inside\u003c\/em\u003e, spray sparingly onto the cloth rather than straight onto the glass, so no mist drifts onto a display or a vent. With a \u003ca href=\"\/en\/products\/the-rag-company-diamond-280-gsm-mikrofaser-glastuch\"\u003emicrofibre glass cloth\u003c\/a\u003e especially, the cloth quality decides whether the loosened dirt gets picked up or just smeared around.\u003c\/p\u003e\n\u003cp\u003eThe second, bone-dry pass over the finished pane lifts the last haze out. That's exactly the step most people skip, and that's exactly where you get the streaks you spot later in backlight. A good glide additive makes the difference here between any old cleaner and a real car glass cleaner.\u003c\/p\u003e\n\u003cp\u003eWhy the cold pane? The additive only works its glide as long as the film is liquid. On hot glass the water flashes off too fast, the cleaner grabs and the cloth just pushes the dirt around. In the shade or early in the morning you've got that window of time. Wash new microfibre cloths once without softener before they ever touch glass too, otherwise they carry sizing onto it that pulls streaks all by itself.\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-glass-cleaner-gc-glasreiniger_anwendung.png?v=1780006597\" alt=\"Koch-Chemie Glass Cleaner Gc being sprayed on a car window and pulled off with a microfibre cloth\" loading=\"lazy\" style=\"width:100%;height:auto;border-radius:4px;\"\u003e\u003c\/p\u003e\n\n\u003ch3\u003eWhat the Gc is built for and what it isn't\u003c\/h3\u003e\n\u003cp\u003eThe Gc cleans glass, it doesn't seal it and it doesn't belong in the washer reservoir.

One verified customer puts it well: with stubborn dirt you need 2 to 3 passes rather than scrubbing under pressure. A short soak and another pull is gentler and quicker in the end, because you avoid scratches you'd have to polish out later.\u003c\/p\u003e\n\u003cp\u003eAnti-fog protection is something the Gc deliberately leaves out. It gets you clean, clear glass, but against fogging from the inside only an anti-fog treatment helps for the long run. Clean glass does fog up far more evenly though, and so far less of a bother than a greasy film.\u003c\/p\u003e\n\u003cp\u003eBeyond the car the Gc cleans mirrors, interior and exterior, motorcycle visors, instrument glass and smooth surfaces around the house like tiles or stainless steel. The only place to be careful is on matte anti-glare nav and instrument displays: there you always spray onto the cloth and work with little pressure, so the coating doesn't suffer. On clear glass and glossy plastic headlights it works with no restrictions.\u003c\/p\u003e\n\u003cp\u003eIn a smoker's car a tacky nicotine film settles on the inside glass, scattering the light and making everything look yellowed.

The commuter grabs the 1-litre bottle, the detailer the 10 or 20-litre container.\u003c\/p\u003e\n\u003cp\u003eGlass cleaners are in highest demand in spring: pollen and bug season drives demand about 40 percent over the quiet winter level. If you've got a bottle in the boot now, you clean the windscreen on the road instead of driving into the low sun with a pollen film and streaks.\u003c\/p\u003e\n\u003cp\u003eDay-to-day the difference shows in the details: no streaks in backlight, no haze on the inside glass that turns oncoming headlights into stars at night. If you drive a lot with the sun low or in the dark, you notice a streak-free pane straight away.\u003c\/p\u003e\n\u003cp\u003eThe Gc is fuss-free on cost: 1 litre ready-to-use lasts many weeks of commuter life depending on how much you spray, and decanting the 10-litre container into a spray bottle costs you far less per litre. Store the cleaner frost-free and the spray function stays reliable across the whole shelf life. An opened bottle in the car survives the summer heat better if it isn't left baking in full sun all the time.\u003c\/p\u003e\n\u003cp\u003eHow often you clean depends on your driving: if you commute daily, keep the windscreen clear inside about every 2 weeks and outside as needed with pollen or bugs. High-mileage drivers and detailers with several cars a day get the most out of the big container and a spray bottle fixed to the trolley. That turns reaching for the car glass cleaner into routine rather than the exception.\u003c\/p\u003e\n\u003cp\u003eThe one trick hardly anyone does and that stops most streaks: clean the inside first, then the outside, and pull horizontally inside, vertically outside. If a streak is left after cleaning, the direction tells you straight away whether it's on the inside or the outside, and you only fix it there. That saves you the third pass and the guessing.

A solvent-based specialist cleaner built on C10–C13 hydrocarbons that chemically breaks down tar, bitumen, oil and grease residue — neat on a dry surface, 30 seconds to 3 minutes dwell time, then rinse off with a pressure washer. Carries Daimler approval and is free of halogenated hydrocarbons.

The active blend — C10–C13 n-alkanes, isoalkanes and cycloalkanes with under 2 percent aromatics — chemically breaks apart the molecule chains in bitumen and tar. The residue runs off in streaks and you either steam it away with the pressure washer or wipe it off with a microfibre cloth.\u003c\/p\u003e\n\n\u003cp\u003eFree of halogenated hydrocarbons, so it's a lot kinder to materials than the old-school tar removers people kept in jerry cans back in the 90s. Available in 1 litre, 10 litre and 20 litre — plus a 2-pack and 3-pack when you need more. Alongside the alkane blend the formula carries a share of 2-butoxyethanol as a coupling agent, which improves how it wets a glass-smooth panel and keeps it working even at cooler ambient temperatures. For indoor use, run ventilation above three air changes an hour, and eye protection is a must for any overhead work.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChemical, not mechanical.\u003c\/strong\u003e You can't polish tar out — scrubbing drags the particles across the paint and leaves swirls behind.

That's the bit manufacturers and rivals rarely mention. If you do nothing after the tar comes off, you're left with unprotected paint that takes on fallout and water spots with no barrier. So always plan it in as the first step of a combo job: tar wash → normal wash with a pH-neutral shampoo → reseal with a \u003ca href=\"\/en\/products\/sonax-profiline-speedprotect-spruhversiegelung\"\u003espray sealant\u003c\/a\u003e or wax. For a spot job (the odd tar fleck on the sill) a quick detailer is enough as local protection. For a full exterior job including resealing, set aside about 45 minutes for a mid-size car.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eSpray it on neat. Short dwell. Steam it off.\u003c\/h3\u003e\n\n\u003cp\u003eThe application is kept deliberately simple. Lay Teerwäsche A on the dry, cold surface undiluted — either straight from the 1-litre bottle with the \u003ca href=\"\/en\/products\/koch-chemie-teerwaesche-a-tea-bitumen-teerentferner?variant=54013040492879\"\u003eCanyon spray head CHS-3AN\u003c\/a\u003e or from a sturdy solvent-safe spray bottle. A wet surface dilutes the solvent and cuts the cleaning power right down — when washing, tar wash first, then shampoo.\u003c\/p\u003e\n\n\u003cp\u003eDwell time runs from 30 seconds to 3 minutes — depending on how thick the tar layer is. You can see when it's working: the tar dissolves into brownish-black streaks and runs down vertical surfaces. As soon as that happens, rinse straight off with a strong jet of water or wipe it away with a clean microfibre cloth. A 1000 ml bottle covers roughly 4 to 6 full vehicle sides with moderate tar.\u003c\/p\u003e\n\n\u003cp\u003eOn bigger areas, don't let it dry — in direct sun or on hot paint above 25 °C the solvent flashes off too fast and leaves an oily film that only comes off at the next wash. For underbody or wheel-arch work on commercial vehicles, the 10 or 20 litre version is the right call.\u003c\/p\u003e\n\n\u003cp\u003eThere you apply it over a wide area with a pump sprayer and then steam it off with the pressure washer at around 120 bar. On stubborn, dried-on bitumen spots after a drive through roadworks, a second application does more than a longer dwell on the first pass — the solvent is saturated after about 3 minutes and stops working.\u003c\/p\u003e\n\n\u003ch3\u003eIt breaks down tar. And wax too.\u003c\/h3\u003e\n\n\u003cp\u003eTeerwäsche A attacks any organic coating sitting on the paint. That's how it works — and at the same time it's the one catch for anyone who reaches for it without a plan. Carnauba waxes, synthetic polymer-based sealants and most quick detailers dissolve away on contact with the hydrocarbon blend. That's no fault in the product either, it's chemistry: what breaks down bitumen breaks down wax too, because both are built on similar organic molecule structures.\u003c\/p\u003e\n\n\u003cp\u003eFor the real world that means two things. First: every tar wash is followed by a full paint wash with a pH-neutral shampoo to neutralise the solvent residue. Second: the treated spot needs a fresh layer of protection.\u003c\/p\u003e\n\n\u003cp\u003eIf you're only dealing with small flecks on the side sill, you can follow up with a spot wax or detailer. If you're cleaning whole panels or the underbody, build the reseal into the workflow as a fixed step. SiO₂-based ceramic coatings usually aren't fully wrecked after a tar-wash treatment, but they lose noticeable hydrophobicity — a topper or detailer brings them back up to level.\u003c\/p\u003e\n\n\u003cp\u003eWhat Teerwäsche A isn't suited to: unpainted soft plastics, rubber seals and EPDM profiles. The solvent swells rubber over longer contact and can dull plastics. It mainly hits window seals, door rubbers and black plastic trim on older vehicles.\u003c\/p\u003e\n\n\u003cp\u003eDon't spray it over those surfaces broadly — if overspray happens, rinse it off with water within 60 seconds. On fresh wraps and PPF (paint protection film), test first on a hidden spot. Plenty of PPF coatings handle short contact times under 30 seconds but react sensitively to longer exposure.\u003c\/p\u003e\n\n\u003ch3\u003eWhen Teerwäsche A fits — and when it doesn't\u003c\/h3\u003e\n\n\u003cp\u003eTeerwäsche A is the right call when you're removing genuine road tar, bitumen spray after driving through roadworks, asphalt residue on wheel arches or dried-on oil films in the underbody area. It's also built for the regular cleaning of car-wash brushes and shop floors — wherever it's not paint cosmetics that's needed but real chemical solving power. In the spring season after winter it's standard for underbody prep, once tar-salt mixes have piled up over months.\u003c\/p\u003e\n\n\u003cp\u003eFor insect residue, though, it's not the first choice. Insect proteins are organic but structured differently — enzymatic cleaners like the \u003ca href=\"\/en\/collections\/insektenentferner\"\u003einsect remover\u003c\/a\u003e work more precisely and more gently on paint there. If you've got both at once — tar on the sill, bugs on the front end — treat both areas separately with the product that fits each. Trying to solve everything with one all-rounder usually ends in more rework. Same goes for tree sap and adhesive residue: both dissolve with the tar wash, but a dedicated tree-sap remover works cleaner.\u003c\/p\u003e\n\n\u003cp\u003eAs for pack size, the 1-litre bottle suits the private user and the occasional detailer planning one go per vehicle. The 2-pack and 3-pack bring the price per litre down by roughly 5 to 15 percent — worth it if there are several vehicles in the household or you want the season's supply locked in.\u003c\/p\u003e\n\n\u003cp\u003eThe 10 and 20 litre drums are trade sizes for reconditioning, underbody cleaning or fleet work — here the outlay only pays off from regular weekly use. For precise single-spot application the 1-litre bottle with the Canyon spray head stays the most ergonomic solution. The spray head delivers a precise cone rather than a mist and doses right onto the problem spot without wetting more area than needed.\u003c\/p\u003e\n\n\u003cp\u003eStore Teerwäsche A frost-free at room temperature. Once opened, the bottle stays stable for about 24 months as long as the cap is closed tight after use — hydrocarbon solvents evaporate slowly otherwise and the concentration drops.\u003c\/p\u003e\n\n\n\u003chr\u003e\n\n\u003cdiv class=\"care-guide\"\u003e\n  \u003ch3\u003eHow to use Koch-Chemie Teerwäsche A\u003c\/h3\u003e\n\n  \u003col\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePrep.\u003c\/strong\u003e Move the vehicle into the shade, paint temperature under 25 °C.

You'll see when it's working: tar dissolves into brownish-black streaks running down the surface.

The result: smeary streaks on the windscreen, juddering wipers, the hydrophobic effect gone. The pro rule: before the first Cep run, recalibrate the pump to 5 to 10 ml, no exceptions, and check the dosing valve after 200 washes. If the conveyor stops for more than three minutes, hit the cars with the pressure washer too — polymer burn-in above 30 °C paint temperature is the most expensive warranty question a site operator can face.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eCep only works when the brushes massage the paint\u003c\/h3\u003e\n\n\u003cp\u003eThe foam arch has to sit before the final brush or Swingtex station, or the water film won't break. Touchless machines give Cep too little mechanical friction, so the hydrophobic effect drops out completely.\u003c\/p\u003e\n\n\u003cp\u003eThe amino-siloxanes aren't passive layer-builders — they only react under pressure. The polymer's nitrogen anchors reach for the clear-coat surface like little magnets, and only once Swingtex or PE brushes press the foam into the paint do the siloxane chains line up and build the hydrophobic layer. What that means for you: without the paint massage the car comes out of the drying arch wet, the blower runs longer, and the meter ticks up with it.\u003c\/p\u003e\n\n\u003cp\u003eThe dosing pump puts out between 5 and 10 millilitres per car — no more. On older machines that ran 30 to 50 ml for other polishes, the balance between foam look and residue on the glass falls apart. A second lever: the paint surface has to stay cool, ideally under 30 °C. In direct summer sun at the exit, foamed-up Cep can dry on before the brushes reach it — and that leaves polymer spots you can only get off with the \u003ca href=\"\/en\/products\/koch-chemie-fine-cut-f601-schleifpolitur-fein\"\u003eFine Cut F6.01\u003c\/a\u003e cutting polish.\u003c\/p\u003e\n\n\u003cp\u003eSetting up a service station from scratch? The \u003ca href=\"\/en\/collections\/koch-chemie\"\u003eKoch-Chemie range\u003c\/a\u003e covers the full car-wash workflow: alkaline pre-wash, neutral main shampoo, Cep in the foam arch, high-pressure rinse, high-output blower. That sequence is also what keeps the machine within the industry specs for paint, plastic and chrome compatibility.\u003c\/p\u003e\n\n\u003cp\u003eThe surfactant system carries a non-ionic helper — in plain terms, a go-between for the water-hating silicone and the water. The surfactant keeps the amino-siloxanes in a foamable solution so the foam pattern stays stable. Day-to-day you notice it in the visual foam arch that operators and end customers both expect. If the foam goes too loose or collapses too fast, the surfactant helper is usually over-dosed — and Cep then gets diluted on the paint too quickly, the hydrophobic effect goes flat and the beading after the dryer disappoints.\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-ceramic-effect-polish-cep-schaumpolitur_anwendung.jpg?v=1780347796\" alt=\"Foam from the Koch-Chemie Cep foam polish on dark paint during application\" loading=\"lazy\" style=\"width:100%;height:auto;border-radius:4px;\"\u003e\u003c\/p\u003e\n\n\u003ch3\u003eCep protects, but it won't correct micro-scratches\u003c\/h3\u003e\n\n\u003cp\u003eThe Cep layer is a sacrificial layer until the next wash, not a 9H coating. If you want lasting paint protection, run Cep over a real \u003ca href=\"\/en\/products\/koch-chemie-ceramic-allround-c0-02-keramikversiegelung\"\u003eCeramic Allround C0.02 ceramic coating\u003c\/a\u003e as the base underneath.\u003c\/p\u003e\n\n\u003cp\u003eClear-coat surfaces, painted alloy wheels, glass, plastic trim and rubber seals all take Cep without a problem. Interior materials are a hard no: leather, Alcantara, upholstery and open-pore plastics soak up the amino-siloxanes for good. On upholstery that turns into stains, on leather a slippery surface — neither comes back. Bare, non-clear-coated aluminium is out too, because Cep has no acidic cleaning action and won't shift brake dust.\u003c\/p\u003e\n\n\u003cp\u003eMicro-dosing is where it pulls ahead. Standard machine polishes sit at 10 to 20 millilitres per car, some foam preservatives even at 50 to 70 grams per car. In practice that means: at 1,000 washes a month a Cep machine gets through five to ten litres of concentrate, against 50 to 70 kilos with a 50-to-70-gram product. That is containers, logistics, storage, drum changes across shifts — the micro-dosing isn't just product cost, it is storage and labour efficiency.\u003c\/p\u003e\n\n\u003cp\u003eThe most common mistake in practice: the conveyor stopping with the foam arch running. When the line stalls, Cep sits on the paint for more than five minutes. The industrial compatibility certificate from the German Automotive Industry Association holds exactly to 300 seconds — think of it as a TÜV-style industry seal that won't attack paint, chrome or plastic inside the defined window. Past that you risk polymer burn-in, especially in summer. The fix: a conveyor-stop SOP for the staff and an emergency pressure rinse in the drying zone.\u003c\/p\u003e\n\n\u003cp\u003eFor where it fits, the rule is simple. \u003cstrong\u003eMachine line with a paint massage → Cep.\u003c\/strong\u003e Hand wash or detail work → the lighter-concentrated \u003ca href=\"\/en\/products\/koch-chemie-ceramic-effect-shampoo-ces-autoshampoo-versiegelung\"\u003eCeramic Effect Shampoo \"Ces\"\u003c\/a\u003e from the same polymer family. Paint correction needed → a cutting or anti-hologram polish with a machine. Cep doesn't replace machine polishing — it is the final seal, not a cut and not a cleaner.\u003c\/p\u003e\n\n\u003cp\u003eCep is built as a pure B2B concentrate. In the machine room, gloves and safety glasses are mandatory kit and an eye wash has to be within reach. In the recycled-water loop Cep is unproblematic: micro-dosing of 5 to 10 ml keeps the active-ingredient concentration in the recycled water below the threshold for the treatment micro-organisms. That is also why Koch-Chemie explicitly clears Cep for biological process-water treatment systems — over-dose it and that clearance is void.\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-ceramic-effect-polish-cep-schaumpolitur_ergebnis.jpg?v=1780347805\" alt=\"Hydrophobic water beading after Koch-Chemie Ceramic Effect Polish Cep on black paint\" loading=\"lazy\" style=\"width:100%;height:auto;border-radius:4px;\"\u003e\u003c\/p\u003e\n\n\u003ch3\u003e20-litre canister for pro machines, not for the home wash\u003c\/h3\u003e\n\n\u003cp\u003eCep is aimed at car-wash operators, gantry systems, dealerships with their own machine and specialised B2B detailers. For a hobby detailer without a dosing pump, the canister simply isn't practical.\u003c\/p\u003e\n\n\u003cp\u003eThe 20-litre pack size is built for machines with diaphragm dosing pumps. Run a gantry at a dealership and one canister covers three to six months depending on volume. A self-service bay only benefits if the dosing gear is fine enough to calibrate — most self-service foam arches sit around 30 ml, outside the Cep spec.\u003c\/p\u003e\n\n\u003cp\u003eAn established best practice from the pro side: Cep as a booster on cars already sealed with a real ceramic base like Ceramic Allround C0.02 or Ceramic Body Cb0.01. The gentle amino-siloxane top-up reactivates the beading on an older coating that has gone flat from traffic film. A fleet on a Cb coating plus a regular Cep pass typically holds its showroom gloss six to nine months longer than a fleet without that combo.\u003c\/p\u003e\n\n\u003cp\u003eRecalibrating an old machine? Best to plan the first 50 washes as a test batch: start the pump at 7 millilitres, then check the beading after the drying arch on 10 random cars. If the water sheets off flat instead of in clean beads, you are either short on foam-arch pressure or the brush contact time is too short. Only then touch the dosing. Put another way: the chemistry isn't the lever, the machine mechanics are. Cep's polymer concentration is already dialled in — everything you do as an operator tunes the activation mechanics.\u003c\/p\u003e\n\n\u003cp\u003eThe trick the manufacturer's brochure doesn't spell out: the polymer layer impregnates the machine's brushes so well that their service life climbs about 20 percent with consistent Cep use. On a typical car wash with two gantry-brush sets a year, that saves a four-figure sum in brush swaps and service work — the biggest hidden bit of economics in this concentrate, and the real reason pro sites rarely give Cep back once they have calibrated their pumps properly.\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-ceramic-effect-polish-cep-schaumpolitur_lineup.jpg?v=1780347979\" alt=\"Koch-Chemie Ceramic Effect Polish Cep 20-litre canister on the workbench\" loading=\"lazy\" style=\"width:100%;height:auto;border-radius:4px;\"\u003e\u003c\/p\u003e","brand":"Koch-Chemie","offers":[{"title":"20 liters","offer_id":57637057298767,"sku":"D1-KCX-683020","price":350.99,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/koch-chemie-ceramic-effect-polish-cep.png?v=1778655965"},{"product_id":"koch-chemie-active-foam-berry-boost-afb-intensivschaum-cranberry-duft","title":"Active Foam Berry Boost \"Afb\" Snow Foam with Cranberry Scent","description":"\u003ch2 id=\"speakable-headline\"\u003eTouchless pre-wash with the Berry Boost snow foam\u003c\/h2\u003e\n\n\u003cblockquote id=\"speakable-summary\"\u003e\n  \u003cp\u003e\u003cem\u003eWhat is the Koch-Chemie Active Foam Berry Boost?

A customer fills their 1-litre pump sprayer with Active Foam for the first time, 20 millilitres of concentrate to 1 litre of water, tightest filter nozzle, lever down. Out comes a thick carpet of shaving foam. Looks spectacular on Instagram, but it doesn't clean. Dense foam clings to the paint instead of running off with the dirt. The Detailing1 rule: 5 ml to 1 litre, medium filter nozzle, and you're after a wet foam that flows off slowly and drags the dirt all the way down to the sill.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eDialling in Berry Boost in the foam-cannon workflow\u003c\/h3\u003e\n\n\u003cp\u003eThe \u003cstrong\u003eBerry Boost\u003c\/strong\u003e needs a setup that matches its concentration: a pressure washer from 110 bar up plus a foam cannon with a stainless filter screen, not a garden pump sprayer maxing out at 0.5 bar.\u003c\/p\u003e\n\n\u003cp\u003eIn the foam-cannon bottle you mix 1:5 to 1:30, depending on how dirty the car is and the water hardness in your region. Hard water (above 14 degrees German hardness) binds surfactants and neutralises part of their cleaning power. You'll want the upper concentration then. With soft water, 1:30 is plenty for a weekly maintenance wash. Go heavy at the start, sparing at the end, and never work from the paint toward the door — foam from the bottom up so run-off marks don't dry on prematurely.\u003c\/p\u003e\n\n\u003cp\u003eBehind the cleaning logic sits simple surfactant chemistry. The concentrate holds 15 to under 30 percent anionic surfactants, water-loving and fat-loving molecules that act like little magnets: one end latches onto dirt particles, the other stays in the water. Since clear coat is also slightly negatively charged, the negative head group pushes the encapsulated dirt away from the surface. What that means for you: the dirt gets wrapped up and carried off with the run-off foam, not rubbed into the paint the way mechanical friction does it.\u003c\/p\u003e\n\n\u003cp\u003eMaximum dwell time on the paint is 5 minutes — binding under the VDA material approval. Let the surfactant mix dry on and the alkaline residue burns into the clear coat, so-called alkaline stains, which only come off with a machine polish. In summer, park the car in the shade first, cool it down quickly with clear water at the open self-serve bay, and only then foam it.\u003c\/p\u003e\n\n\u003cp\u003eIn cold weather the concentrate turns viscous. Before the first fill of a foam cannon in winter, take the bottle indoors for a bit, otherwise the feed pressure stalls and you get inconsistent mix ratios. A \u003ca href=\"\/en\/collections\/zubehoer-detailing\"\u003efoam cannon\u003c\/a\u003e running a steady 110 bar solves the problem mechanically.\u003c\/p\u003e\n\n\u003cp\u003eConsumption in the foam-cannon workflow runs 50 to 100 ml of diluted mix per car, so roughly 5 to 10 ml of concentrate per car. On that basis the 21 kg drum washes between 2,000 and 4,000 cars. For a self-serve bay with a dosing pump it's 3 to 8 ml neat per car, which doubles the yield. Both figures apply to moderate dirt. With pollen in spring or after salty weather in winter, lean toward the upper limit, otherwise the dirt sticks in the foam instead of running off with it.\u003c\/p\u003e\n\n\u003ch3\u003eMildly alkaline strips carnauba. If you love wax, read on here\u003c\/h3\u003e\n\n\u003cp\u003eThe honest limitation of the \u003cstrong\u003eBerry Boost\u003c\/strong\u003e is also its biggest strength: the mildly alkaline character. It reliably dissolves grease from bug splatter, road film and old quick-detailer residue, but it also loosens that last coat of natural wax.\u003c\/p\u003e\n\n\u003cp\u003eCarnauba waxes and light polymer sealants react over time to alkaline surfactants. Carnauba is chemically a plant wax that gets broken down bit by bit through repeated saponification. Picture wiping a candle down with washing-up liquid again and again — eventually it's gone. After several weekly washes the beading goes flatter, the water creeps instead of rolling. If you lovingly look after your car at the weekend with a hand wax or a spray-wax top-up, you shouldn't reach for Active Foam for the weekly maintenance. For that niche the pH-neutral \u003ca href=\"\/en\/products\/koch-chemie-gentle-snow-foam-gsf-reinigungsschaum\"\u003eGentle Snow Foam \"Gsf\"\u003c\/a\u003e is the better call, same maker, different job.\u003c\/p\u003e\n\n\u003cp\u003eWith modern ceramic coatings the story is different. A ceramic layer is a cross-linked glass lattice, permanently bonded to the paint, far more stable than a wax film. Mildly alkaline foams can't touch it.\u003c\/p\u003e\n\n\u003cp\u003eMore than that: the alkaline foam pulls oily traffic-film residue out of the micro-pores of the ceramic. If your 18-month-old coating suddenly no longer rolls but crawls, that's often not material damage but a clogged surface. A concentrated Active Foam wash burns that contamination clear and the beading comes back. That's the off-label use the pros know about, but you won't find it on any manufacturer's brochure.\u003c\/p\u003e\n\n\u003cp\u003eThe second concrete limit: the foam must not dry on. At outside temperatures above 25 degrees or in direct sunlight, the water in the foam evaporates within seconds. The surfactant concentration shoots up locally and burns into the clear coat as an etch mark. If you wash in summer: car into the shade, cool it down with clear water, only then lay the foam on. If you're working without shade: keep strictly to the 5-minute maximum dwell time and rinse off immediately before the next section.\u003c\/p\u003e\n\n\u003cp\u003eWhat the Berry Boost \u003cem\u003ecan't\u003c\/em\u003e do: shift baked-on brake dust on wheels. For that you need the acid-based workflow with the \u003ca href=\"\/en\/products\/koch-chemie-magic-wheel-cleaner-mwc-felgenreiniger\"\u003eMagic Wheel Cleaner \"Mwc\"\u003c\/a\u003e. The foam keeps wheels clean when they're already clean — it's care, not a reset.\u003c\/p\u003e\n\n\u003ch3\u003eFor commercial detailers, not for the Sunday wash\u003c\/h3\u003e\n\n\u003cp\u003eThe 21 kg drum with SKU D1-KCX-695-20L-01 is aimed at the pros: gantry-wash operators, detailing businesses, commercial detailers foaming several cars a day. In the DACH market the search for touchless pre-wash is climbing right now — over the last eight weeks snow foam has averaged about nine percent more search volume than its twelve-month average. The market is pulling noticeably toward the foam cannon.\u003c\/p\u003e\n\n\u003cp\u003eAt 5 ml per car in a hand wash, the drum lasts for around 4,000 cars. That's the scale of a detailing business doing five to ten cars a day that won't reorder for two years. For a hobbyist with one wash a week, this container size is simply overkill. If you want the berry scent at home, wait for the 1- or 5-litre fills, or stick with the \u003ca href=\"\/en\/products\/koch-chemie-active-foam-af-intensivschaum\"\u003eActive Foam \"Af\"\u003c\/a\u003e with sandalwood scent, which comes in smaller sizes in the range.\u003c\/p\u003e\n\n\u003cp\u003eIn a B2B context the VDA Class A approval is the real reason to buy. The German carmakers have tested and cleared the formula on original materials. That's more than just a marketing seal, it's the material guarantee in black and white.\u003c\/p\u003e\n\n\u003cp\u003eIf you stick to the maximum concentration of one percent on the paint and a 5-minute dwell time, the foam demonstrably doesn't attack paint, plastics, chrome parts or rubber seals. For a detailer washing premium cars with wraps or paint protection film, that's the legal footing against damage claims. A US import without this approval may be chemically similar, but in court, in the event of damage, it's worthless.\u003c\/p\u003e\n\n\u003cp\u003eThe off-label use we see most often in enquiries is the wheel-bucket hack: a shot of Berry Boost in the separate wheel bucket of the two-bucket method. On regularly maintained wheels with no baked-on brake dust, the mildly alkaline foam fully replaces reaching for the aggressive acidic wheel cleaner. The wheel comes up clean and the wheel's clear coat stays untouched.\u003c\/p\u003e\n\n\u003cp\u003eThat workflow is exactly what the OEM approval had in mind: not just for the main wash, but for every spot on the car where a cleaner touches the paint. The trick no manufacturer prints in its brochure, because it undercuts the sale of a separate wheel cleaner: a concentrate that keeps clean wheels clean saves you the aggressive acidic product for the genuine hard cases.\u003c\/p\u003e\n\n","brand":"Koch-Chemie","offers":[{"title":"20 liters","offer_id":57637057495375,"sku":"D1-KCX-695-20L-01","price":108.99,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/koch-chemie-active-foam-berry-boost-afb-intensivschaum-cranberry-duft_20-liter.png?v=1778704441"},{"product_id":"koch-chemie-ultra-foam-uf-snow-foam-stark-schaeumender-schaum-sb-waesche","title":"Ultra Foam \"Uf\" Snow Foam \/ High-foaming foam for the self-service wash","description":"\u003ch2 id=\"speakable-headline\"\u003eSnow Foam at pH 8.5 as the sweet-spot between gentleness and cleaning power\u003c\/h2\u003e\n\n\u003cblockquote id=\"speakable-summary\"\u003e\n  \u003cp\u003e\u003cem\u003eWhat is the Koch-Chemie Ultra Foam?

The diagnosis is nearly always the same: pH 9.5 cleans reliably, but breaks down polymer sealants over the weeks. Moving to pH 8.5 cuts the alkaline load by a factor of 10 and cleans almost identically in daily work. If you run decon washes before machine polishing, stick with Active Foam — if you maintain sealants, Ultra Foam is your pick.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eMixing Ultra Foam: cold bodywork, a thin film, five minutes\u003c\/h3\u003e\n\n\u003cp\u003eSpray Ultra Foam neat onto the paint and you risk caustic stains on anodised trim — in the foam lance, pull it down to a maximum of one percent working concentration and never work it undiluted.\u003c\/p\u003e\n\n\u003cp\u003eThat concentration is also the threshold at which the mildly alkaline cleaning action visibly kicks in. In the consumption channel of gantry wash systems, dosing typically sits at 3 to 8 ml per car. In the hand wash, dilutions up to 1:300 are plenty for a straight maintenance wash. In practice that means: a 1L bottle covers around 200 car pre-washes in the hand wash, the 5L drum roughly 1,000 applications.\u003c\/p\u003e\n\n\u003cp\u003eThe bodywork has to be cold and in the shade. Above 25 degrees of air temperature or in direct sun, the carrier water dries off faster than the mild alkali can work — the local concentration climbs, and you get water spots on the paint or milky haze on anodised aluminium trim. From what we see day-to-day: always check paint temperature with the flat of your hand; if the paint feels warm, hit it with a flush of water first until it's below skin temperature.\u003c\/p\u003e\n\n\u003cp\u003eApply in cross passes from the bottom up so run-off marks don't dry on.

In unheated self-service bays the viscosity loses its flow and the dosing pump draws unevenly.

What that means for you: your coating's lifespan stays intact. Polymer sealants also last noticeably longer than under pH 9.5 — that factor of 10 in alkaline concentration translates directly into measurably longer protection-layer life.\u003c\/p\u003e\n\n\u003cp\u003eThe honest limitation: thinly applied carnauba waxes can still be undermined under weekly high concentration (1:10 instead of 1:100). Carnauba is a plant-based ester wax that gets broken down bit by bit by repeated contact with alkali. If you maintain a hand wax as a value-protecting layer, you don't run Ultra Foam at full strength as a weekly maintenance foam — for that niche the pH-neutral \u003ca href=\"\/en\/products\/koch-chemie-gentle-snow-foam-gsf-reinigungsschaum\"\u003eGentle Snow Foam \"Gsf\"\u003c\/a\u003e stays the better call, same maker, different use case.\u003c\/p\u003e\n\n\u003cp\u003eOn glass and unpainted polypropylene the product is uncritical as long as it doesn't dry on.

If you prep ex-lease returns with a spray sealant to follow, you want a foam that gets the paint uncompromisingly clean in under five minutes — without already starting to break down the next car's sealant.\u003c\/p\u003e\n\n\u003cp\u003eActive Foam at pH 9.5 cleans a touch faster, but breaks down polymer sealants over the weeks. Gentle Snow Foam at pH 7.5 preserves the sealant perfectly, but leaves bug splatter and summer sap sitting on the front end. Ultra Foam lands exactly in between.\u003c\/p\u003e\n\n\u003cp\u003eWhat makers rarely flag prominently: Ultra Foam replaces the DIY cocktails that pro detailers used to mix — pH-neutral foam with a splash of all-purpose cleaner — to bump up the cleaning power for a while. Those mixes are chemically unstable, the cleaning action swings from batch to batch.\u003c\/p\u003e\n\n\u003cp\u003eUltra Foam delivers the mildly alkaline pre-mix as a repeatable, stable formula straight out of the canister — the decisive time advantage for businesses with repeatable workflows.
