My uncle brought his van over yesterday for me to take a quick look at his wheels. He has been bad this winter and didn't give his aluminum wheels any attention. He's got brake dust galore in the pits of his wheels. I've got the mothers powerball and polish, but was wondering what you all recommend as far as a good wash for the aluminum. I'm very hesitant about using something that could possibly stain. I'm heading over there Wednesday to work on them, so any info or suggestions you have would be appreciated.
