Dr. Wack "P21S" P21S "HIGH END" Wheel Cleaner 1000ml

Dr. Wack P21S "HIGH END" Wheel Cleaner – uncompromising power, easy on the metal

How does the Dr. Wack P21S "High End" Wheel Cleaner work?
It pulls even baked-on brake dust, oil and rubber off the wheel on its own thanks to a clinging gel and a colour indicator – fast, gentle and even when it's cold out.

The Dr. Wack P21S "High End" Wheel Cleaner is the premium wheel cleaner for anyone who wants flat-out cleaning power without putting paint, metal or seals at risk. Alloy, chrome or painted wheels – the thick gel formula clings instead of running off, lifts even burnt-in brake residue and gets you a visibly clean result in just a few minutes. Made for keen drivers and enthusiasts who care about shiny wheels and a safe job.

• Maximum cleaning power: Reliably clears even heavy brake dust, oil and rubber residue – no scrubbing by hand.

• Gentle gel technology: Doesn't run off, clings for ages and cleans deep without attacking sensitive surfaces.

• Safe for wheel and sensor: pH-neutral and fine for TPMS sensors.

Gel formula & colour indicator – how the cleaning works

The special gel formula in the P21S "High End" Wheel Cleaner was built to grab onto the wheel and stay put. Instead of running off, the gel sits evenly across the surface – even on vertical faces. That gives the active components longer to work and they bite harder. Over the dwell time (about 3–5 minutes) they cut through layers of brake dust, metal particles and oil residue. The signature colour indicator shows you the progress: once the cleaner turns purple to black, the dirt is lifted and rinses straight off. That colour change comes from iron complexation – a visible sign the chemistry is doing its thing.

How to use it & the right dwell time

Using the Dr. Wack P21S "High End" Wheel Cleaner couldn't be simpler or safer. Spray it evenly onto dry, cooled-down wheels – best from about 20 cm away. Then let it dwell for 3–5 minutes, until the purple colour is clearly showing. After that, rinse off well with a strong jet or pressure washer. With really baked-in grime a soft wheel-brush set gives it a hand. Important: don't use it on hot wheels or in direct sun. The cleaner is fine on all materials, including delicate TPMS sensors. Thanks to the pH-neutral formula there's no corrosion on metal, paint or plastic parts.

Results, material safety & where to use it

The P21S "High End" Wheel Cleaner delivers no-compromise results – even where other products tap out. Brake dust and burnt-in particles come off completely, with no reworking and no brush needed. The wheels get their original shine back, with no dull film or streaks. Its high material tolerance makes it ideal for every wheel type, including chromed or polished surfaces. Even in cold weather it keeps working hard, which makes it the perfect all-year cleaner. For full care we'd suggest laying down a wheel sealant like Dr. Wack P21S Felgen-Wachs after cleaning – it protects against fresh grime long-term and makes the next clean easier.

How to clean your rims with P21S High End

Spray the rim cleaner evenly onto dry, cooled rims from a distance of about 20 cm. The gel formula adheres even to vertical surfaces and does not run off, allowing the active ingredients to work on the dirt for a long time.

Let the gel sit for 3-5 minutes. The active indicator shows your progress: as soon as the cleaner turns violet to black, the brake dust is dissolved. For heavily baked-on dirt, use a soft rim brush to assist the process.

Rinse thoroughly afterwards with a strong jet of water or a high-pressure cleaner. Never use the product on hot rims or in direct sunlight. The cleaner is pH-neutral and suitable for all common rim types as well as TPMS sensors. Apply a rim sealant afterwards for longer protection.
