The alloy wheels are clear coated, so don't use a metal polish. Don't use any mag or aluminum polish. It won't do anything, except make the clearcoat finish look hazy. You need to treat your wheels just like you do your body paint.
Just wax 'em. Or use regular polish first if there is some stuck on or embedded dirt.
Also be careful with spray wheel cleaner. Don't use anything real strong. I just wash the wheels with a mitt and soap, once I am done with the body. Always do the wheels last; you don't want to rub the body paint with a mitt that has brake dust in it.
