I just use a brush and some good old car wash soap and water, and then hand dry with a microfiber towel.
Once in a while I'll hook them up with some ICE.
I use this stuff. AWESOME!!! Especially on my GF IS250 AWD. It gets RIDICULOUS brake dust from being AWD and the pads that Lexus uses, and it comes out like new. I'll take before and after pics sat when I do the weekly car wash sat. LOL I use a plastic bristle scrub brush and a tiolet bown brush to get in the wheel spokes. you wet the wheel, spray the stuff on. copunt to 10 and scrub the wheel and the dirt melts off. Great product!!! :w00:
