I have 17" 5ziegen wheels on my car and I haven't cleaned them very often. They kinda looked better dirty (darker bronze.) but now that I have tried cleaning them I have noticed that there is this gunk on them that just will not come off. And I have no idea what it is. Its definitely not brake dust. I have taken my steam gun to them. Nothing.
What product can take this stuff off without hurting the finish on the wheels? It doesnt look like corrosion, its above the finish. Which makes me think it can be taken off. Also, what the hell is it?
