I wanted to sell my aluminum rims. Outside were the wheels were cleaned so frequent this place but on the inside it was at the wheels fitted not properly ran, especially the front wheels were by 5 years by black branded brake Taub. After the wheels had dismounted, I tried it with burlap and wheel cleaner. Also additional brushes and high-pressure cleaners did nothing. After lay Search I ordered with the Tuga Set of 2 from Amazon. The first time spraying with the Greens could watch how the dissolved scharz crusts. Of course, not everything went off at the first time, but after two further applications which aluminum wheels also are inside as clean as the outside. A devil, I'm thrilled. Now I can see the wheels also sell.
