Koch Chemie Magic Wheel Cleaner is an acid free wheel cleaner that does not dry up even after an extended dwell time on the surface. Iron particulate is broken down- typical with an iron remover, but you also get the power to clean dirt and grime from the wheels with a formulation that will get a little sudsy during agitation.
Apply to painted wheels, steel wheels, and also effective on chrome in good condition. Application should only be carried out on cool wheels, out of direct sunlight.
As with any wheel cleaner, you have to know what works for your situation. If you are ever unsure about the compatibility of a cleaner with your wheels, it's best to revert to a pH neutral soap or foam along with agitation. A compromised finish (extensive pitting or flaking of the finish) can be further compromised by any cleaning chemical as well as water under high pressure.
