Park ToolCB-4 Bio ChainBrite Cleaner(Return to Product Page)

This is the only chain cleaner I've used over the last 25 years. Nothing better.

I have used Park Chainbrite for years and it works great.

I use it in a chain cleaning device and it really cleans the chain to new . Plus , I feel that cleaning my chain thourghly makes it work better , and last longer.

Great product.

I use this with my Park Tool chain cleaner for a fast complete chain cleaning. Works great, no toxic odors.

I recommend this product. It got my bike chain shiny running it thru the chain contraption. I used it with a toothbrush on derailleur gears. I did wipe down after.

I like that item is so good.

Great for cleaning chain & cassette. Have used for years and it's great!

Cant verify if its actually 100% biodegradable, but it does a decent job as the liquid in a Park Tool chain cleaning tool. In a pinch, you can get quite a bit clean just squirting into a rag as well.

This is easy to use with the park tool chain cleaning tool and cleaned our chains really well.

Along with the Park chain scrubber it does a nice job cleaning the chain. I also use it on a rag to remove grease from the frame.

Cleans quicker than others I�ve used in the past.
