i used this stuff called wheel max, if the name is wrong, when i go home ill reply again but im pretty sure its the right name. you DO ONE RIM AT A TIME!!... spray it with the hose then spray the wheel max all over the rim. wait one minute, no longer then rinse wit the hose thoroughly! then dry. it takes off anything! i always have that brake dust on it and it takes it right off. u dont even have to scrub, just wait. youre gonna have to wear sunglasses to look at your clean rims!!
