I just take a dry microfiber cloth and wipe down the wheels, barrels and all, about once a week. Takes about 5 minutes per wheel and looks great. If there is any tar or gunk that gets stuck, I use a little adhesive solvent and it gets everything absolutely squeaky clean. That said, cleaning my car is great mental "down time" for me. Nothing like a Saturday afternoon in my garage with some beer, some music, and my cleaning products !!
