Review on 🚴 16 fl oz/472 ml Bottle of Park Tool CB-4 Bio Chainbrite Bicycle Chain & Component Cleaning Fluid by Ryan Williams

Great chain cleaner. I alternate using this and the spray on the cleaner. I use it for my really deep cleaning. I use an old marinade jar (cleaned thoroughly) and add a few inches of Park Chain Cleaner. I take the chain off the bike and let it sit for 5-10 minutes. Then I shake the jar to get rid of any remaining dirt and grime. The chain comes out fine. After removing the chain, I let the solution sit, sometimes overnight. I then use a coffee filter in the funnel to filter the solution and pour it back into the bottle. I can usually recover about 75% after each use.
