It all rests on a nozzle you can adjust from a finer spray pattern right up to a heavier wetting – and SOLO explicitly highlights a new\/adjustable universal nozzle that gives a more balanced jet and spray pattern and dials in more precisely to the job.\u003c\/p\u003e\n\u003cp\u003eDay-to-day in detailing, that “adjustability” is more than a comfort feature: on interiors you often want controlled, fine coverage (e.g. onto a microfibre cloth or a brush) so you don’t flood every crevice. For pre-treatment or large-area cleaning you want even, quick coverage without the product running straight off in fat drops. You only get that range when the spray pattern and pressure stay stable – and that’s exactly where a pump sprayer proves itself as a process tool.\u003c\/p\u003e\n\u003ch3\u003eUsing the FKM EPDM A B marking and pH 1-7 7-14 the right way\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eA\/B\u003c\/strong\u003e isn’t a cosmetic model variant for SOLO, it’s a clear chemistry signal. SOLO sets out the split so that units marked “B” are meant for bases\/alcohols in the pH 7–14 range, while “A” covers the acidic side; on top of that the seal materials (EPDM vs. FKM) are matched accordingly. That matters in detailing, because we rarely run “just one cleaner”: APC, pre-cleaners, dedicated surface cleaners – they can all be chemically very different.\u003c\/p\u003e\n\u003cp\u003eWhat that means day-to-day: if you run typical alkaline cleaners, pre-treatments or lots of alcohol-based work, you go for the B version (EPDM). For acidic media or special jobs down in the low pH range, the A version (FKM) is the right call. For the 305 B, SOLO describes the EPDM seal and the pH 7–14 range, for instance, and for the 305 A the FKM seals and the pH 1–7 range – exactly the logic you want to get “right” the moment you buy.\u003c\/p\u003e\n\u003cp\u003eAnd yes: with pump sprayers too, the unglamorous pro move applies – rinse it out after use.

In detailing it's often not just the product that decides the result, but how you lay it down: too coarse = wasted product, too fine = it dries off, wrong seal = headaches. That's exactly where the CLEANLine series plays its strength: 303 A and 303 B are built the same technically, but sealed differently for the chemistry – so you run acidic and alkaline cleaners each in the right system.

If you work with acidic specialist cleaners in detailing (classics: lime\/mineral-based deposits, water spots and rust film on suitable surfaces, depending on the product), then the A version is the logical grab – not because „A is better“, but because the seal matches the medium. The other way round, the \u003cstrong\u003eEPDM seal (303 B)\u003c\/strong\u003e is designed for alkaline cleaners in the pH 7–14 range; SOLO describes EPDM as the seal material for basic\/alkaline applications and also notes it suits disinfecting solutions. In practice that means: for typical all-purpose cleaners (APC) and many degreaser\/pre-wash scenarios you're very often in the green with 303 B, while 303 A is your safe bet when you deliberately work acidic. Our tip from the day-to-day: if you regularly spray both alkaline and acidic, genuinely grab both versions – that's not a gimmick, it's clean chemistry hygiene. And if you love your bottle parking spots: the CLEANLine even has a card\/label system in the spray head, including coloured marker cards – great for keeping contents and uses apart (and yes: it very effectively prevents the „oops, wrong cleaner“ moment).\u003c\/p\u003e\n\u003ch3\u003eCar pre-wash and detailing: applying cleaning chemistry in a controlled way with a pump sprayer\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eCar pre-wash\u003c\/strong\u003e lives off chemistry clinging evenly and getting to work – not off you sending half of it into the air as mist. That's exactly what the 1.25-litre format is strong for: handy, quick to fill, and big enough to do a car in one go without topping up constantly (fill volume 1.25 L). The adjustable hollow-cone nozzle lets you trim the spray pattern so you get more coverage or more punch depending on panel size and dirt – without changing the character of the product. For us day-to-day that's the sweet spot for: pre-cleaners\/pre-sprays on lower areas, APC on sills\/door shuts (with the right pH version), and targeted wetting of problem zones.\u003c\/p\u003e\n\u003ch3\u003e3 bar spray pressure, hollow-cone nozzle, safety valve and continuous spraying for a clean pattern\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003e3 bar spray pressure\u003c\/strong\u003e on a hand pump sprayer isn't a pub-talk number, it's the point where the spray pattern and your work rhythm get stable: pump, spray, keep going – without running „empty“ after three trigger pulls. SOLO quotes 3 bar for both 303 models and pairs it with a safety valve that can drop the pressure for emptying\/refilling and automatically vents over-pressure. On top of that there's the encapsulated pump unit, which shields the pump elements from the cleaning fluid being dispensed – a detail that in day-to-day simply means: less contact between the mechanism and aggressive chemistry, and so a more robust, more consistent function over time. And because we love it in detailing when things „just run“: the lock slider for continuous spraying is gold when you want to wet larger areas without sending your finger to the gym. If you need more of a „foam blanket“ than a spray film, take a look at one of our foam sprayers\/foamers as an add-on – the pump sprayer then stays your tool for pre-sprays, targeted wetting and working „by feel“.\u003c\/p\u003e","brand":"solo","offers":[{"title":"1.25 liters \/ Acid (pH 1-7) 303 A","offer_id":56938331111759,"sku":"D1-SOL-30301","price":18.33,"currency_code":"EUR","in_stock":true},{"title":"1.25 liters \/ Alkaline (pH 7-14) 303 B","offer_id":56938331078991,"sku":"D1-SOL-30302","price":18.33,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/solo-cleanline-303-a-pumpsprueher-1-25-liter.png?v=1769854142"},{"product_id":"solo-cleanline-304-a-b-pumpsprueher-2-liter","title":"CLEANLine (304 A \/ B) Pump Sprayer 2 Litres","description":"\u003ch2\u003eSpray on purpose, not by guesswork: solo CLEANLine (304 A \/ B) — 2-litre pump sprayer for clean, controlled chemical work\u003c\/h2\u003e\n\u003cblockquote\u003e\n\u003cp\u003e\u003cem\u003eWhich solo CLEANLine (304 A \/ B) — 2-litre pump sprayer fits your cleaner? 304 A covers acidic to neutral media (pH 1–7) with FKM, 304 B handles neutral to alkaline media (pH 7–14) with EPDM – both up to 3 bar.\u003c\/em\u003e\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\u003chr\u003e\n\u003cp\u003e\u003cstrong\u003esolo CLEANLine (304 A \/ B) — 2-litre pump sprayer\u003c\/strong\u003e is to detailing what a clean torque wrench is to mechanical work: control.

SOLO deliberately splits the CLEANLine by pH window: if you’re laying down concentrated or diluted acids in the pH 1–7 range, tools with FKM seals are the right pick; once it goes alkaline (pH 7–14), EPDM is the seal material that goes in. \u003c\/p\u003e\n\u003cp\u003eFor you as a detailer it translates beautifully into plain terms: if you run typical acidic jobs (say acidic cleaners that go after mineral residue and deposits), that belongs in the A world – and that’s exactly what 304 A is for. If your day-to-day runs more alkaline (classic: lots of pre-cleaner\/APC\/degreaser setups meant to break down organic grime), 304 B is the clean call. The point isn’t „acid good \/ alkali bad“ – the point is material compatibility and consistency: seals have to seal and move while they’re in contact with the medium. Mix it up wrong here and you rarely notice on the first spray – you notice later: pressure drops faster, the action gets rougher, small parts age for no reason.\u003c\/p\u003e\n\u003cp\u003eNice to know (because it really comes up in practice): with FKM, SOLO also mentions suitability for oil-based and partly chlorinated-hydrocarbon media. That’s no free pass for experiments, but it explains why a lot of pros like to stay in the FKM world for „chemically demanding“ media – as long as the pH use fits. And since we don’t do detailing in a lab but between the wheel, the sill and the door shut: if you run several media side by side, the A\/B logic is the simplest way to avoid mistakes. Label the contents, match the tool to it, done.\u003c\/p\u003e\n\u003ch3\u003eUsing 3 bar pump pressure, an encapsulated pump and an adjustable universal nozzle in detailing\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003e3 bar pump pressure\u003c\/strong\u003e sounds technical at first – but it’s really the difference between „constantly re-pumping“ and „working in a clean flow“. With the 304s, SOLO describes how the efficient pump lets you reach an operating pressure of up to 3 bar with little effort, giving you long enough working intervals. That’s what makes the sprayer so pleasant in everyday car care: you can wet a panel evenly without the spray going tired after ten seconds.\u003c\/p\u003e\n\u003cp\u003eThe second pro building block is the fully encapsulated pump unit. SOLO explains that the encapsulated pump shields the pump elements from the chemically active cleaning fluid and so helps it last. Translated: less direct „chemical stress“ in the mechanical heart of the thing, less risk that the pump feel or the seal tightness gets worse over time – as long as you don’t treat the tool like a throwaway after use (more on that in a second).\u003c\/p\u003e\n\u003cp\u003eAnd then there’s the part you feel right away on every job: nozzle and handling. SOLO names a new, adjustable universal nozzle for a more balanced jet and spray pattern, and on the 304 B explicitly the adjustable hollow-cone nozzle, which lets you set spray volume and pattern. Add ergonomic controls, a comfortable trigger lever and a lock slide that lets you switch between continuous and spot spraying while you work. That’s pure gold in detailing: spot-on at badges, shut lines and edges – and the next moment broad across pre-wash zones, without cramping your hand or chopping up your workflow.\u003c\/p\u003e\n\u003cp\u003eBadly underrated, but a real quality indicator day-to-day: filling and standing. Per SOLO the tank is made of sturdy, UV-resistant polyethylene, stands on three feet, has a wide filler opening and a fill-level mark in the semi-transparent material. That’s not „nice“, that’s time saved: mix faster, spill less, set it down cleanly – and if you work professionally, those are exactly the details that make the session pleasant.\u003c\/p\u003e\n\u003ch3\u003eCleaning, releasing pressure and workflow tips for long enjoyment from your pump sprayer\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eCleaning and releasing pressure\u003c\/strong\u003e on a pump sprayer isn’t the boring chore – it’s the part that preserves your spray quality. SOLO describes a safety valve you use to release the tank pressure for emptying, refilling or cleaning, and that any pressure above 3 bar is bled off automatically through this valve. For your routine that means: after working, bring the pressure down in a controlled way first, then open – not the other way round. That keeps it clean and predictable.\u003c\/p\u003e\n\u003cp\u003eIf you’re after consistent results in detailing, build yourself a simple routine: after use, empty the leftover medium, rinse with clean water, run one pass of water through it (so the nozzle and lines are clear too), then store it dry and clean. That stops residue drying on the valves and nozzle and ruining your spray pattern next time. And yes: with the more „active“ cleaners it pays off twice, because that way you don’t leave the seals sitting in the medium permanently. The original operating manual shows, among other things, cleaning and care steps plus dismantling\/checking the nozzle parts – a good reminder that a tool like this earns some care if you want it running like a pro tool.\u003c\/p\u003e\n\u003cp\u003eHandy (and pretty smartly solved): on the 304 B SOLO names a card slot built into the spray head for marking the tank contents, including the writable media cards supplied. For you that means: no more „wasn’t that the wheel cleaner… or?“ – you label cleanly by use case and automatically grab the right one in the flow.

This is exactly where SOLO splits the variants strictly by use: the 305 A is intended for acidic media in the pH 1–7 range and runs FKM seals; the 305 B is meant for alkaline media in the pH 7–14 range and uses EPDM. That’s not a marketing gimmick, it’s materials science: elastomers behave differently depending on the chemistry – and the best pump is useless if the seals swell, harden or simply start leaking. So if you regularly switch between “more acidic” and “more alkaline”, matching them up properly is the basis for predictable results and stress-free work.\u003c\/p\u003e\n\u003ch3\u003eUse in detailing: pre-wash, wheels, engine bay \u0026amp; workshop – how to really use 5 litres efficiently\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003ePre-wash and alkaline cleaners\u003c\/strong\u003e are the sweet spot for a lot of people – and that’s exactly what the 305 B (EPDM, pH 7–14) is built for: you wet large panels fast and evenly, let the surfactants do their thing and cut down on mechanical contact in the next step, because the dirt has already been “loosened”. For acidic jobs (depending on the product logic, e.g. when you’re going after limescale or certain mineral deposits) the 305 A (FKM, pH 1–7) fits – the key is to always stick to the intended medium instead of playing “it’ll probably be fine”. Day-to-day that means: you use the sprayer as an application tool, not a stand-in for a foam lance. For real foam dwell time you grab a dedicated foam sprayer; the CLEANLine 305 is made to lay liquids down under control.\u003c\/p\u003e\n\u003ch3\u003eSpray pattern, 3 bar build-up and handling: why the CLEANLine 305 A\/B feels so “pro”\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003e3 bar working pressure and a flat-jet nozzle\u003c\/strong\u003e are the combo that just works day in, day out: you get an even film of liquid instead of a random landscape of droplets. Max spray pressure sits at 3 bar; the oversized piston pump builds it up in just a few strokes – you notice that straight away when you’re working larger panels and don’t want to top up the pressure every 20 seconds. The 5-litre tank is deliberately built tough; the CLEANLine catalogue highlights, among other things, the very high tank robustness for the 305 models (including a 7 mm wall thickness) plus a carry strap, a base foot and ergonomic controls. In practice that means: a stable stance while pumping, clean handling when you move it around and less “fiddling” during breaks, because the lance can be stowed properly. The key specs are clearly trimmed for everyday work too: 5 L nominal volume, a 50 cm spray tube and a 1.4 m hose, plus an empty weight of around 2.6 kg (depending on model\/spec) – compact enough for the car, but big enough for serious surfaces. And yes: a safety\/relief valve for releasing pressure is part of the deal, so you can let the pressure off under control instead of fighting the cap.\u003cstrong\u003e\u003c\/strong\u003e\u003c\/p\u003e","brand":"solo","offers":[{"title":"2 liters \/ Acid (pH 1-7) 305 A","offer_id":56938499080527,"sku":"D1-SOL-30505","price":62.32,"currency_code":"EUR","in_stock":true},{"title":"2 liters \/ Alkaline (pH 7-14) 305 B","offer_id":56938499047759,"sku":"D1-SOL-30506","price":62.32,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/solo-cleanline-305-b-pumpsprueher-5-liter.png?v=1769856475"}],"url":"https:\/\/detailing1.fr\/en\/collections\/solo-pumpsprueher.oembed","provider":"Detailing1","version":"1.0","type":"link"}
