There is an excellent cleaner that I have found works better than "Mother's" products or Meguire's.
It is called "Flitz" Aluminum and Magnesium polish/cleaner.
It's not sold in too many retail stores,but can be ordered online. See the links below.
Your wheels are coated with urethane clear,the same product used over the base coat color on the body.Use any wax or light polish you would use on the body,don't use metal polishes of any kind because you're polishing paint,not aluminum.
