Good H.D. Wheel Cleaner
June 6, 2014
At my detail shop we use P21S gel cleaner on almost every car we clean for the first time. Thats because the gel cleaner cleans the heavy buildup of brake dust on dirty neglected wheels. Once they are clean, periodic cleaning with P21S regular strength is much easier.
Pros:Good for dirty wheels!
Cons:Don't mix with regular strength cleaner. Use one or the other.
