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

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.

I've been using ChainBrite for years and have been super happy with the results. Combined with a Park chain cleaner it can't be beat. Only other need is an old toothbrush to get in the small spaces. Rinses off easily with warm water.

This stuff works very well. I clean my chains, cassettes, etc. in the backyard and unlike other bio cleaners, this one does not burn my grass.

This is the de facto standard for chain degreasers. I've used others and they've worked fine as well, but for some reason, I always go back to buying this brand. It gets the job done for sure. I run the chain through the PT chain cleaning tool twice, cleaning the tool out in between runs, and the chain ends up so sparkly clean you could eat off of it.

This is the first time I used this cleaner and was very happy with the results.

Works great with Park Chain Cleaner

I.ve used this for several years to clean chain and the chain drive. Works well, I also so water and Dawn

Clean up chain before lubing

This cleaner makes it so easy to get your chain clean when used with the Park Tool CM-5.3 Cyclone Chain Scrubber or another chain scrubber tool. I use it about every 3 weeks/600 miles. Fast, simple and effective. It's amazing what a good chain cleaning and lube will do.

I buy this regularly to clean my chain with, using the park tool plastic cleaning thingee that clamps onto the chain.

This product works great with the Park Tool cleaning device. The bottle does not last super long but it gets the chain very clean. It's the main cleaner that I use.

Cleans the chain or any greasy part with ease. Dirty fluid is safe and easy to get rid of.

I use this cleaner to completely de-grease chains when using lubes that require total removal of existing lubes. The Park solution cuts through everything on your chain with minimal scrubbing, though I recommend a chain cleaner tool with resevoirs and brushes to control the mess.

The best cleaner and Lub. for cleaning and providing protection and lub for our chains using the Chain cleaner tool

I use Park Chain cleaner in my chain cleaning device and it does a great job. I also use it to clean my pedals . I use an old toothbrush to clean the nonchain areas of my bike as well. Works great .

I use this with the PArk chain cleaning device, and get good results. I clean every 250 miles, and get 6000 miles out of a cassettechain combo, easy.
