Step one. Wash aluminum with wrong cleaner on rims that haven't been cleaned in years...
Step two. Take a 11" wool cutting pad for your high speed rotoray buffer and slather it with mothers. Then go over the rim a few times to get off all the water spots
Step three. Wipe everything off, clean with some sort of degreaser, then go over rim with power ball...
End result
Buffing/polishing aluminum takes time. I had about an hour into each rim to make them look that good.
