Review on Park Tool CG 2 4 Bicycle Cleaning by Nikith Brewster

Degreaser and brush are ok. The cleaning tool is too complex and not durable - The bristles come off, you have to catch these bristles while cleaning the chain - The degreaser drips from the cleaning tool. If you remove the chain, you can clean the sprockets, derailleur and front sprockets separately without the chain. - Cleaning a dirty chain uses almost all of the degreaser that comes with the kit. It's $15. For $20 you can get a new chain, clean and already lubed (9 speed SRAM in my case)! If your chain has a quick link, just skip this set. Buy a 32-48 oz wide mouth plastic jar, put a chain in it, add water + dish soap, shake it. Repeat until clean. Then repeat once with a degreaser. Then let it dry and apply lubricant. You will save money, time and significantly improve your condition. The only exception would be if your chain cannot be removed without breaking the link (although there is a very small limit to how many times it can be removed and reinstalled), but even then it would be better to have a quick link for yours Chain to buy Make chain removal easier if necessary.
