My 2014 StreetGlide Special has those "mag type" aluminum wheels with a brushed finish along the rim edge. Not sure what the hell it was, but something "splashed" up onto the brushed surface of the front wheel and left a whitish splash mark in several spots.
Whatever it is, it seems to have "tatooed" itself to the surface. I've tried polishing compount and other polishes and nothing seems to faze removing those spots. I had months before, applied that S-100 (Anti corrossion) spray to those surfaces on both wheels, but it didn't seem to stop these spots/splashes from occurring.
I was thinking about trying some vinegar but believe I read somewhere that one shouldn't apply that to aluminum.
Any ideas on what might get these spots off my rims..............
