BMW, Mercedes, Porsche, Audi, VW and Volvo all use and recommend P21S Wheel Cleaners to remove brake dust and road grime from their alloy wheels. This wheel cleaner has the best reputation for wheel safety of any product available.
P21S is a non-acid, water-based detergent that safely cleans all painted, clear-coated, polished or anodized wheels.
P21S Gel formula is 50% stronger for wheels with excessive brake dust coatings. I recommend the Gel formula for any car that creates excessive brake dust.
500 ml. spray bottle. Imported from Germany.
I would recommend this item to a friend.
Wheel Cleaning my 2011 Corvette GS
March 21, 2012
The product works as advertised and I followed the instruction completely. The pump action on the bottle leaves a little to be desired as a longer throw ofthe handle or a more generous quantity emitting from the nozzle would help, no much pumping.
Pros:Went on well and stayed in place Brake dust rolled off Simple but yet good amount of rinsing cleaned up good
Cons:the pump action on the bottle
Best wheel cleaner I have found!!!
July 18, 2011
I looked all over for a wheel cleaner that actually cleaned my white summer wheels. The wheels have lots of spokes so scrubbing them by hand is a time consuming job - but the only way I knew to get them really clean. Every other spray on wheel cleaner said I needed to be careful not to leave it on too long. So I was spending an hour just washing wheels. I order P21S gel cleaner and it really does what it says. I can spray my wheels and let it stand for a bit - maybe 10 minutes - and then just hose them off with the spray nozzle on the hose. My wheels are white painted with a clear coat finish. This cleaner gets them really clean and shiney without harming the finish.
