Ive been a simple green and purple power purchaser for a long time now. Last weekend after malvern I decided to give Shout a try. Ill never be using anything else again. At dollar general its $4 a gallon and cleans everything up really nice. Even adds a nice scent when the bike is inside. Also, Matrix 1.7 cleaning solutions "Pre-Ride" treatment in the blue bottle, eats any two stroke drool instantly. I recommend giving it a try on any drool on rear brake calipers/side panels. Never once have I used it for its intended purpose though, seems like a waste.
