Best way to clean tired aluminum wheels ?

i use 1000 grit wet and dry sand paper light sand clean then mag polish as long as the wheel has not got a coat of clear on them

X2. I did this on an old set of U.S. Mags. There was no clear coat to worry about. There's no magic stuff for old aluminum wheels, just lots of sandpaper, polish, and days of elbow grease. Mine went from heavily oxidized from years sitting outside to where I could see my reflection. Lots of work.
