I’m not going to lie... I didn’t except this stuff to work as well as it did! Ive tried all kinds of different wheel cleaners over the years including chemicals guys strongest wheel cleaner they make with no luck. I basically had 5 years worth of brake dust on my work truck and figured I’d try this product before I gave up on my wheels. Well I’m a believer and I’ll let the pictures do the rest of the talking. The steps I used I sprayed on the product straight and scrubbed the wheels with a traditional wheel cleaner cone style brush, allowed it to dwell for 15 mins while reapplying the cleaner to prevent it from drying and then rinsed them off with garden hose pressure.
