First of all, I'm not one of these car freaks who sits for hours at a rim in order to clean them to a shine. I prefer straightforward. I'm going to the car wash, the syringe wheels before washing with detergent and that must have been it. In the trunk, I keep a small spray bottle with cleaner while I now auffülle with the Tuba Aluminium Devil. This stuff is awesome. Although the wheels already have a thick black layer with brake dust, the cleaner does not do all the work. The agent turns red after a few moments, runs down and the aluminum rim comes to light glossy. In this package - 5 liter canister - absolutely price- and recommended.
