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.
I have tried other brands and chemicals. This one seems to be the best spray on and rinse off chemical that I have used to date. If you are on the fence, get this.
So my sons and I tried this new wheel cleaner against our current inventory from PA, S, PS, and A, ( initials to protect the innocent). We used two identical AMG brake cars, and the test began! Well the Magic happened as described!!! the Magic cleaner stuck to the wheels and calipers noticeably better - giving a thick layer of cleaning on the wheels, etc . This allowed the cleaner to work longer and required less agitation than the other products. The other products are great but this was noticeably better. Easier to use and I found myself using less product than the others because of the thickness, stickiness of the cleaner. All three of us agree that this was our new favorite cleaner for wheel cleaning. Thanks for bringing these new products to us!!!
