I had some baked on brake dust, water spots, dirt, and other junk that nothing would take off of my chrome wheels. I found this stuff at autozone called Blue Magic and with very little effort, it made the wheels look brand new. It was only $6, and well worth it, works on polished alluminum, Chrome, stainless, billet. Just thought I would share.

^^^ good stuff!! I use it. Its truck-stop grade stuff.
