My car sat for a few months and didn't get washed, now my rims are all messed up and have some killer oxidation on them. Any ideas of what to use? Someone suggested wd40 and said it's good and cleaning it up if I wash it off after rubbing it on real quick. ANyone heard of this? I was thinking a clay bar but that just sounds like to much a pain in the ass, but if I need to I will. Hoping you can help guys!
