I just wash mine when I wash the car and repolish them about once every 2-3 months, depending. I use Mothers aluminum polish on an arbor (buffing wheel) with a drill (2500rpm), but I use white rouge every now and then.
I too am having a horrible time keeping mine polished well..I use the mothers power ball and it works awesome..thing is..I dont think the standard mothers aluminum polish is cutting it on the aged wheels..is the mothers thats like 10 bucks for the really small container worth the money? seems like it says billet polish or something...what other polish will give the absolute best results?
