Review on Park Tool CG 2 4 Bicycle Cleaning by Brian Krump

Very easy to use - I ordered extra bottles of cleaning solution because what is in the kit is enough for about 3 cleanings. I was able to hold the cleaning tool in my left hand while stepping backwards with my right hand to pass the chain through. I dip the brush in the cleaning solution and clean the cartridge. It cleans so well! Thanks to this tool, I'm becoming obsessed with the clean chain! I do all this outside, I put on medical exam gloves to keep my hands clean, wipe the chain and everything down with a microfiber cloth after cleaning, then apply some lube to the chain and then let everything air dry overnight ( I put paper towels under the bike in case I missed any wet spots that would drip). The cleaning tool is easy to rinse with clean water; I like that it's biodegradable. Overall very happy with this set!
