I use a foam gun to wash the wheels/car, I start with the weels and water rinse, then foam the wheels up. I a use sheepskin wash mitt dedicated for the wheels only. The key is to use a good wax/sealant on your wheels, this helps aid the cleaning process. For drying, I recommend this from chemicalguys.com
Or, I'll use my electric shop vac (the top comes off and I can use it as a blower).
