I have an old set of wheels on my wife's car and we left them on last winter. I think that's part of the problem. The wheels have a polished lip and the lip is supposed to be shiny and silvery of course. Instead, they are cloudy and rough looking and there's some brown spotty clouds that look like rust may be on the way. Does anyway know what's good to clean the lips? Plain old regular wheel cleaner isn't cutting it. I'm thinking I need something special or a buffer or something. Any help would be appreciated. Thanks.
