The best polish I have used is called Purple and you can get it at truck stops or some vendors have it at the bigger shows. I have used all kinds of polish including Mothers, Blue Magic,Wenol, Never Dull and the Purple has the best after shine to where it takes a whole lot more time to oxidize back up. Now mind you im talking on big rig fuel tanks that are subjected to all kinds of weather conditions and get dirtier faster than your wheels but you want a polish that not only cleans but stays that way longer. Use some kind of buffer wheel or ball and that should save some time as well as have more effect while polishing.
