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

Works Well, Large Bottle
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.

Satisfied!
This is a refill order after my first purchase of a starter kit. The cleaning device and cleaner fluid brought my chain back to spotlessly clean. Very happy.

Best chain de-gunker I've ever tried.
The first time I used this chain cleaner, I had forgoten that my sticky, black chain was actually silver! Use this fluid in your favorite chain cleaning machine (I like the Park Tools manual chain cleaning machine). Always amazing (and disgusting) to see when you clear the black water out of your cleaning machine. I wipe my chain down after every ride, and use this chain cleaner after every two or three rides.It will increase the lifetime of your chain (and likely the sproket and chain rings as well), and likely allow more of your power to transfer to the wheels.
