This is the best maintenance wheel cleaner. It will clean a moderately dirty wheel but will require more product and scrubbing. You can use it to clean the tires at the same no need for multiple products. I also use it to clean plastic floor mats and as bug remover making it very economical and now I buy it 5 gallons at a time.

AWESOME...This product cleans off everything on my rims without harsh chemicals and requires no elbow grease.

The good news is it's dilutable and cleans wheels and tires. You'll have to guess as to dilution ratios because it doesn't say on the bottle. I tried 7 to 1. I didn't get my wheels entirely clean which is probably my fault for neglecting them for too long. The contamination became baked-on and nothing short of sanding them is going to remove it. For whatever it's worth, I also tried Meguiar's Ultimate Wheel Cleaner which didn't do the job either. Did make some improvement though.

Wear gloves when using Brake Buster. I got some on my left hand which I used to apply the product and my hand turned red and broke out in little red spots. My right hand, which did not come in contact the product was fine.
