If its oxidation, skip all of those products and grab the flitz or blue magic................fast!! lol!!! Polished aluminum and/ or chrome oxidation is a special kind of grime that a paint cleaner WILL NOT remove. The aim is to remove this dirt without scouring the wheel. Flitz and Blue Magic are formulated to remove aluminum and chrome oxidation without scrubbing off layers of the surface (non-abrasive). You won't go wrong with either one, but flitz I would say from experience is just a bit stronger, so if you think that it will be a challenge, then try flitz first and see how you like the result. Good luck.
