SONAX PROFILINE FelgenReiniger wheel cleaner (SONAX) 5000ml

Wheel cleaner in pro-size containers — SONAX PROFILINE FelgenReiniger for detailing shops

Why does a detailing shop need a professional wheel cleaner? This pro wheel cleaner is an alkaline cleaner in bulk sizes up to 200 litres — it pulls brake dust, road grime and baked-on crust off alloy wheels, steel wheels and coated wheels efficiently and without harming the surface.

Wheels are the dirtiest parts on the whole car: brake dust from ceramic and metallic pads, baked-in road grime and oil splatter from the engine bay combine into a layer that bakes on under hot braking and barely shifts without a strong cleaner. At the same time, wheels are often made of sensitive aluminium alloys or carry high-grade coatings that aggressive acid cleaners can attack. The SONAX PROFILINE FelgenReiniger handles all of this: as an alkaline cleaner with no hydrofluoric-acid content, it pulls stubborn brake dust and wheel grime without touching the wheel surface. Available in 1 litre, 5 litre, 25 litre and 200 litre for non-stop professional use.

• Alkaline formula, no hydrofluoric acid — gentle on every type of wheel. Wheel cleaners with hydrofluoric acid are very effective, but they attack aluminium surfaces, clear-coat finishes and chrome trim — and over time it shows up as dulling and staining. The PROFILINE FelgenReiniger works with alkaline actives that break down brake dust and grime without chemically damaging the wheel surface. It's safe on cast-alloy wheels, chrome wheels, coated wheels and steel wheels — one product for the whole shop, no sorting by wheel type.
• Pro sizes up to 200 litres for cost-effective daily use. On the consumer side, wheel cleaners come in 500 ml or 1 litre — for shops running dozens of cars a day, that makes no economic sense. The PROFILINE FelgenReiniger comes in pro sizes up to 200 litres, so you can keep filling spray bottles and pressure sprayers for daily work. The price per litre in the 25-litre or 200-litre size is far lower than the 1-litre format — a real cost advantage for any shop that burns through a lot of wheel cleaner.
• Fast dwell time for an efficient wash-bay workflow. In professional washes and detailing shops, dwell time matters: products that need a long soak slow you down when several cars are going through at once. On typical wheel grime, the PROFILINE FelgenReiniger shows visible results after just 1–3 minutes of dwell time — the brake dust loosens up and can be rinsed off or agitated with a wheel brush, no hard scrubbing needed.

Detailing1's tip from the shop: For the best results, spray the PROFILINE FelgenReiniger onto dry, cool wheels — not onto hot wheels straight after a drive, or the product flashes off too fast and can leave stains. Let the wheels cool down first (at least 10 minutes after the engine's off), then spray on the cleaner, let it dwell for 2–3 minutes, work it with a suitable wheel brush and rinse thoroughly. For stubborn baked-on brake dust, bump the dwell time up to 5 minutes and don't let it dry out — re-wet it if you have to. For extreme brake dust, the PROFILINE FelgenReiniger Red Max is the stronger option with a colour indicator.

How the PROFILINE FelgenReiniger works — alkaline actives and brake-dust release

The PROFILINE FelgenReiniger works with a pH-alkaline active system that softens the bonds between brake-dust particles and the wheel surface. Brake dust is made up of fine metal particles (iron, copper), carbon from the friction lining and organic binders. Heat from braking bakes these particles onto the wheel surface — especially on warm alloy wheels, which act as a heat sink for the brakes.

The alkaline actives in the FelgenReiniger break down both the organic binders and the oxide bonds between iron particles and the aluminium surface. The result is a dirt matrix that, after enough dwell time, lifts off the wheel completely with water and a bit of brush work — without heavy mechanical pressure or aggressive acids. On wheels that get cleaned regularly, a light film often comes off with just a rinse, no brush; on neglected wheels, dwell time plus brush work is the most efficient route.

The pH of the PROFILINE FelgenReiniger is set so it stays gentle on aluminium alloys: strongly alkaline cleaners (pH > 13) attack aluminium and can damage the anodising on alloy wheels. The PROFILINE FelgenReiniger balances cleaning power against material compatibility for non-stop professional use, with no risk to high-grade wheel surfaces.

One important point in professional use is the right dilution. The PROFILINE FelgenReiniger is a concentrate that you can use neat or diluted depending on how dirty the wheel is. For light, fresh dirt after a normal drive, a dilution of 1:3 (1 part cleaner, 3 parts water) is plenty. For stubborn baked-on brake dust after long standing time or hard track use, run it neat. Diluting cuts product use while still cleaning well, and it brings the cost per cleaned wheel right down.

Using the FelgenReiniger — dwell time, brushing and rinsing

The standard process for wheel cleaning in the shop: do the wheels before you wash the body. Spray the wheel cleaner onto a dry or pre-wetted wheel — good coverage across all areas matters, including the inner face of the spokes and the brake areas behind them. Let it dwell for 2–3 minutes. Work it with a wheel brush (a spoke brush plus a flat wheel brush), getting into every area of the wheel. Rinse thoroughly with a strong jet of water — residue can leave stains once it dries.

For automated wash-line processes, go with the 25-litre or 200-litre size: the product gets fed into the machine's wheel-cleaner tank and sprayed onto the wheels through the automatic dosing. Dwell time in a tunnel wash is short (30–60 seconds), so you should run a slightly higher concentration, or treat heavily soiled wheels by hand afterwards.

For mobile detailing, the 1-litre format in a spray bottle works well — enough for 8–12 cars per fill. If you're reordering regularly, the 5-litre size is an economical refill option.

On frequently asked questions: yes, the PROFILINE FelgenReiniger is also fine on cast-alloy spoke wheels with a vapour-coated or polished aluminium surface, as long as you don't overrun the dwell time. Polished alloy wheels (so-called "Diamond Cut" or machined wheels) react more sensitively to chemical cleaners than painted wheels: on these special wheels, let the cleaner dwell for 2 minutes max, rinse straight away with water and don't use an abrasive brush. The alkalinity of the cleaner can cause tarnishing on polished aluminium if it dwells too long — at normal dwell time the risk is minimal.

Where the PROFILINE FelgenReiniger fits — washes, reconditioning and mobile service

In a fixed reconditioning shop, the PROFILINE FelgenReiniger is the standard product for wheel cleaning before every car detail. Even on cars going in for polishing or sealing, the wheels need to be clean — brake dust on the wheels would get flung onto the freshly polished paint by spray water during the job and create new scratches. Cleaning the wheels as the first step of every detail with the PROFILINE FelgenReiniger is a must, not an option.

Car dealers reconditioning used cars get through a lot of wheel cleaner: every car in intake recon needs clean wheels before it hits the showroom. The 25-litre size covers the demand of an average-sized dealership for several weeks and saves a lot of ordering hassle and cost compared with smaller sizes.

The PROFILINE FelgenReiniger compared — the wheel-cleaner range at SONAX

The SONAX PROFILINE wheel-cleaner range has two main products: the PROFILINE FelgenReiniger (this product) and the PROFILINE FelgenReiniger Red Max with a colour indicator. The Red Max contains an iron indicator that turns reddish on contact with iron particles from brake dust, so you can see exactly where the brake dust is — handy for visually checking the cleaning result and for showing the customer ("look how much brake dust was on your wheel"). The standard FelgenReiniger without a colour indicator is usually cheaper and plenty for shops that don't need the colour reaction.

On the consumer side, SONAX offers the SONAX FelgenBeast wheel cleaner — a strongly alkaline wheel cleaner with especially fast action. The PROFILINE FelgenReiniger is built for non-stop use in bulk sizes, while the FelgenBeast is a consumer format for occasional use. For shops that demand very fast action and cleaning power and don't mind the cost in bulk sizes, the Red Max in 5-litre or 25-litre can also be an option.

Buying the SONAX PROFILINE FelgenReiniger — sizes and cost comparison

The PROFILINE FelgenReiniger comes in four sizes: 1 litre (for mobile use and getting started), 5 litre (for smaller shops and as a 1–2 month stock), 25 litre (for mid-sized shops as a quarterly supply) and 200 litre as a bulk size for large washes and fleet operators. The right size depends on your monthly use: at 10–15 cars a month the 5-litre size is ideal; at 50+ cars a month the 25-litre pays off, and for industrial use the 200-litre.

For shops trying the FelgenReiniger for the first time, start with the 1-litre format to test the cleaning power on your own fleet. Once you're sold, move up to the 5-litre or 25-litre and enjoy the lower price per litre. As a verified SONAX dealer, Detailing1 carries every size of the PROFILINE FelgenReiniger.

One thing that often gets underrated day-to-day: picking the right brush. A good wheel cleaner only shows its full potential paired with a suitable wheel brush. For spoke wheels, go with a flexible spoke brush that reaches into tight gaps; for solid-face wheels, a flat bristle brush that covers the whole inner face is ideal. If you only spray and rinse without brushing, you'll always leave residue in the recesses and along the inner edges of the spokes on heavily soiled wheels. Investing in a good set of brushes is as much a part of professional wheel cleaning as the right cleaner.
