Very good cleaning product for both tires and rims, safe for both. Additionally, it has anti-corrosion protection for the discs and prevents the formation of stubborn rust when dried. It is diluted 1:3 with a foam generator for rich foam and effective cleaning action

It's awesome (in tires). No recommendations needed. Removes the brown tint they develop over time. I've done each wheel 4-5 times and it still works! You can also use it diluted with water.
