I use this with my Park Tool CB-2.4 Chaingang Cleaning System. The bottle that originally came with the CB-2.4 tool wasn't as large as this bottle, but it lasted 2.5 cleanings. This bottle lasts about 4 cleanings. It works well and doesn't stain the cement if it drips/splashes, but I typically lay an old towel on the floor when using this stuff. It's biodegradable so that's plus. It doesn't smell bad at all and is easy to use. Great product.

The bike cleaner arrived very quickly. This cleaner with the Park chain cleaning tool does the job perfectly! I've tried other products - this is the best!

Initially had problems with the order, retailer took responsibility and provided solution promptly. In term of the product can't fault Park Tool quality. Has a nice smell to it too.

Works well, but expensive for what it is. Did a great job cleaning my chain.
