SONAX PROFILINE Glass Cleaner (Concentrate) 10l

Professional Glass Cleaning in Bulk — SONAX PROFILINE GlassCleaner Concentrate

What is the SONAX PROFILINE GlassCleaner? The highly concentrated glass cleaner concentrate for professional use — streak-free cleaning of all vehicle glass, mirrors, and glass surfaces, available in 10-liter, 25-liter, and 200-liter containers for businesses with high consumption.

In car washes, vehicle detailing businesses, and fleet management, glass cleaner consumption is significant: Every vehicle has several square meters of glass surface that need to be cleaned inside and out during detailing. Professional demand cannot be met economically with small 500 ml bottles. The SONAX PROFILINE GlassCleaner is the concentrate for precisely these requirements: Highly concentrated glass cleaner formulation in bulk containers — 10 liters, 25 liters, and 200 liters — which, when diluted, yields many times the amount of ready-to-use glass cleaner. Streak-free cleaning performance on windshields, side windows, rear windows, mirrors, and glass surfaces of all kinds — professional, economical, and available in commercial bulk sizes.

• Highly concentrated glass cleaner concentrate for economical bulk needs — 10 L, 25 L, 200 L. The SONAX PROFILINE GlassCleaner is formulated as a concentrate that, when diluted, yields many times its original volume. For professional businesses that treat many vehicles daily, the concentrate format is significantly more economical than buying ready-to-use glass cleaners in small containers. The three container sizes suit various business sizes: from small detailing workshops (10 liters) to large fleets or car washes (200 liters).
• Streak-free cleaning performance on all glass types — inside and out. The formulation of SONAX PROFILINE GlassCleaner is optimized for streak-free results on vehicle glass: rain and limescale streaks on exterior windows, greasy film and fingerprints on interior windows, silicone residue from window seals on the glass surface — all these contaminants are completely and residue-free removed with the GlassCleaner. On the interior window, cleaning performance is particularly relevant: greasy film on the inside of the windshield significantly impairs vision due to light reflection.
• Fast-acting and quick-drying — no annoying re-wiping necessary. The SONAX PROFILINE GlassCleaner dries quickly and leaves no residues that would require a second wipe. In professional operation, working speed is crucial — a glass cleaner that dries streak-free on the first wipe saves several minutes per vehicle compared to products that need to be re-wiped.

Practical tip from Detailing1: Fill the SONAX PROFILINE GlassCleaner directly from the bulk container into SONAX PROFILINE Sprayboy spray bottles at the correct dilution ratio — label the dilution ratio on the bottle body. For exterior cleaning, dilute slightly more, for stubborn interior dirt (greasy film, smoker's film), use more concentrated. When cleaning windshields internally, wipe the window with the SONAX PROFILINE Microfiber Cloth Glass in a criss-cross pattern — first pass horizontally, second pass vertically — this prevents smearing of the greasy film and ensures a streak-free result. Never work in direct sunlight on hot glass — the cleaner dries too quickly and leaves streaks.

Formulation and Concentrate Strength — What distinguishes the SONAX PROFILINE GlassCleaner

Before you start cleaning, it's worth taking a look at the glass surface in glancing light — ideally with a detailing headlight or under room lighting from a shallow angle. This reveals all streaks, the typical interior greasy film, and limescale spots that are easily overlooked without this check and can lead to unpleasant surprises after cleaning. A quick check before and after cleaning immediately shows whether the result is truly streak-free — or if a second wipe is necessary.

The glass cleaner formulation of the SONAX PROFILINE GlassCleaner is based on a surfactant-alcohol mixture that is tailored to the specific types of contamination found on vehicle glass. Exterior windows are primarily affected by inorganic residues: limescale from rainwater, mineral dust deposits, fine dust, and lubricating oil aerosols from driving. Interior windows have a different contamination characteristic: The typical interior greasy film is caused by outgassing of plastics and foams in the vehicle interior, amplified by smoke, body fats from hands and hair, and cleaning agent aerosols. Both types of contamination can be effectively removed with the GlassCleaner.

The alcohol content in the formulation ensures rapid evaporation after application — this prevents streaking due to excessively long exposure or uneven drying. The surfactants dissolve the fat-based and mineral contaminants, emulsify them, and allow for complete wiping without residue. The ratio of surfactant to alcohol is balanced so that the GlassCleaner flows well and acts quickly even at low outside temperatures (winter operation), without freezing on cold glass.

Another advantage of the concentrated formulation: The product is more stable and has a longer shelf life in its concentrated state than ready-to-use glass cleaner. Ready-to-use glass cleaners can lose effectiveness during prolonged storage under unfavorable conditions (frost, direct sunlight). The concentrate remains fully effective for many months, even with fluctuating temperatures — a clear advantage for businesses that maintain larger inventories.

As a concentrate, SONAX PROFILINE GlassCleaner is designed for dilution with water. The typical dilution ratio for normal glass contamination, depending on the concentration level and degree of dirt, is 1:5 to 1:20 — so one liter of concentrate yields 5 to 20 liters of ready-to-use glass cleaner. For a 10-liter canister, this corresponds to a supply of 50 to 200 liters of ready-to-use product — with a consumption of approximately 50-100 ml per vehicle for interior and exterior cleaning, a 10-liter canister is sufficient for 500 to over 2000 vehicle treatments.

Dilution and Application — Optimal Concentration for Different Use Cases

The correct dilution of SONAX PROFILINE GlassCleaner depends on the degree of contamination and the area of application. For standard cleaning of exterior windows with normal road dirt (dust, rain spots, light grease traces), a higher dilution is sufficient — less concentrate, more water. For more stubborn contamination such as heavy greasy film on interior windows, residue typical of smoker's cars, or silicone residue from sealing rubbers, a lower dilution (higher proportion of concentrate) is more efficient — fewer wiping passes, faster results.

In professional operations, a two-stage dilution system is recommended: One spray bottle with standard dilution for normal cleaning, a second bottle with a more concentrated mixture for stubborn interior contamination. Both bottles are filled from the same bulk container, allowing for flexible use without changing products. With the SONAX PROFILINE Sprayboy as a standard spray bottle, the GlassCleaner system seamlessly integrates into the rest of the SONAX PROFILINE operational setup.

For car washes and automatic washing systems, there are special dosing devices that draw the glass cleaner directly from the 200-liter container and flush it into the system at the correct concentration. The SONAX PROFILINE GlassCleaner is compatible with such dosing systems — the formulation is designed to deliver optimal results even with machine application and subsequent rinsing. For manual application, the spray bottle method is the recommended option.

GlassCleaner vs. Glass Detailer — The Right Glass Cleaning Product for Every Application

In the SONAX PROFILINE glass cleaning range, in addition to the SONAX PROFILINE GlassCleaner, there is also the SONAX PROFILINE Glass Detailer Concentrate — two products that differ in concept and application. The GlassCleaner is the basic cleaner concentrate for complete glass cleaning: it removes all dirt, leaving a clean, residue-free glass surface. The Glass Detailer Concentrate is a specialist for the final step: it cleans and impregnates simultaneously, giving the window a hydrophobic treatment after cleaning and improving the water repellent effect on the window.

The workflow order is clearly defined: first, thoroughly clean and degrease with the GlassCleaner, then optionally refine the glass surface with the Glass Detailer Concentrate. Applying the Glass Detailer to a not completely degreased window leads to uneven impregnation and streaking. The two products are complementary, not interchangeable — the GlassCleaner as the cleaning base, the Glass Detailer as the finishing layer.

For businesses that only want to stock one glass cleaning product, the SONAX PROFILINE GlassCleaner is the right choice: It covers 90% of glass cleaning requirements — clean, streak-free windows without residue. The SONAX PROFILINE Acryl+GlasReiniger, on the other hand, is designed for special requirements such as acrylic glass, Plexiglas, and acrylic glazing — not as a replacement for the GlassCleaner, but as a supplement for applications with sensitive plastic glazing.

Material Compatibility and Application Limits — What the GlassCleaner can and cannot tolerate

The SONAX PROFILINE GlassCleaner is approved for all standard vehicle glass types: single-pane safety glass (ESG), laminated safety glass (VSG), tinted glass, heated rear windows, and normal side windows. The formulation is alkali-tolerant, clear coat compatible, and can also be used on surfaces adjacent to body paint — the GlassCleaner does not damage paint pigments or clear coat if it accidentally gets on painted surfaces. However, for targeted cleaning, it should primarily be applied to glass surfaces.

For plastic glazing made of acrylic glass (PMMA) or polycarbonate (PC) — such as found in motorcycle fairings, classic car windows, boat roofs, or special vehicle bodies — the SONAX PROFILINE Acryl+GlasReiniger is the better choice. Harsh surfactants and alcohols in normal glass cleaners can attack plastic glazing in the long term, dulling or embrittling it. The SONAX PROFILINE GlassCleaner is optimized for real glass, not for plastic glazing.

On coated windows — e.g., after applying SONAX PROFILINE Glass Detailer Concentrate or another glass sealant — the GlassCleaner can also be used: The glass sealant remains intact with regular cleaner use, as long as no aggressive solvents are contained in the product. On sealed windows, the GlassCleaner dries even faster because the hydrophobic coating accelerates the runoff of the cleaner — this improves the result in practice and often requires less product than on unsealed windows. For the care of films (PPF, tinting film), the GlassCleaner should not be sprayed directly onto the film — it is better to apply it to the cloth first and then to the surface to avoid edge detachment.

Buying SONAX PROFILINE GlassCleaner — Container Size and Application Recommendation

The SONAX PROFILINE GlassCleaner is available in three container sizes: 10 liters for smaller businesses and detailing studios, 25 liters for medium-sized detailing operations and car washes, 200 liters as a drum for large operations, fleets, and car washes with very high daily consumption. The choice of the right container size depends on consumption: For 10–20 vehicles daily, the 10-liter canister is the economical choice; for 50–100 vehicles daily, the 25-liter canister. The 200-liter drum only makes sense for very high consumption and sufficient storage space.

For mobile detailers who carry the GlassCleaner concentrate in their vehicle, the 10-liter canister is manageable and provides an extensive supply for many weeks of operation. The canister with a plastic drain tap can be mounted directly in the vehicle or on the PFA trolley — daily refilling of spray bottles is quick and clean without lifting and tipping the canister.

For mobile detailers who carry the GlassCleaner concentrate in their vehicle, it is also recommended to label the spray bottles with a waterproof marker or labels — when working on the road or at a customer's site, confused cleaners can quickly lead to unwanted results. If you pre-portion several SONAX PROFILINE products into spray bottles at once, you should use a separate color label or spray boy type for each product to avoid confusion. An established labeling system saves time and prevents errors in daily operations.

The SONAX PROFILINE GlassCleaner Concentrate is an economical basic product that should not be missing in any professional vehicle detailing operation. The concentrate logic — buy once, use many times — makes it the most cost-effective glass cleaner approach for businesses, and the professional cleaning performance for streak-free results without re-wiping is the decisive quality feature in daily operations.
