Review on Park Tool CG 2 4 Bicycle Cleaning by Joe Gosa

My wife and I have a tadpole recumbent tricycle (two wheels in front and one in back). This means that each of us has a long chain. This tool allows me to do multiple passes on both bikes in a very short amount of time, around 15 minutes if I'm very thorough. Even with the "grunge brush" I would spend more time on each one. Now I spend more time cleaning the cleaning tool than cleaning this entire chain. The only minor complaint I have is cleaning the detergent itself. If you've just cleaned a chain with grease, it tends to stick to the bottom in the "pockets" that hold the plastic together. Dirt and dust wash off easily, but grease needs to be brushed off. Good thing everything can be taken out of the vacuum cleaner so I can get there.
