This wheel cleaner is made from premium biodegradable ingredients and is safe for all types of wheels. More importantly, it's safe for you and the environment. No worries about what's going down the storm drains. Any wheel cleaner that touts spray-on, spray-off with no rubbing is a danger to you and our planet. Unique penetrants allow for far less effort when cleaning wheels. The high concentrate allows the cleaner to hang on the wheel longer to clean stubborn brake dust, road oils and other deposits. A superior product with no expense spared toward the ingredients. BBS manufactures the finest wheels for most of the top automotive manufacturers in the world: Ferrari, Lotus, Porsche, BMW, Toyota, Audi, Volkswagen, Daimler, Chrysler, Jaguar, Mazda, Volvo, Mitsubishi, Subaru, AMG, Citroen, Opel, Pininfarina, Saab, Peugeot, and Alpina. I am proud to say that BBS has approved Griot's Garage Wheel Cleaner for all of their wheels. Dayton Wire Wheel Company has also approved Griot's Garage Wheel Cleaner for all of their wheels. Works great with our exclusive 3 Finger Detail Mitt, Lambskin 4-Finger Mitt and our Foam Swabs.
