P21S wheel cleaner gel
November 23, 2014
This product cleans old brake dust inside an alloy wheel like no other. I like the fact that it can be left on for a few hours rather than a few minutes like it's competitors before hosing off.
Pros:1. Gel clings to wheel surface better than watery products. 2. Gel can be left on wheel for up to 2 hours for thick or stubborn brake dust before it's hosed and toweled off.
Cons:1. A bit pricier than it's competition.
