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

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

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.

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

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

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.

I like that item is so good.

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.

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

Works great with Park Chain Cleaner

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.

I use a couple of different products to clean my bike including the Park Tool ChainBrite Cleaner and the Spin Doctor Degreaser from Performance Bikes. I find that the Park Tool product does a much better job on my chain but costs more. I therefore use the ChainBrite on my chain and the Spin Doctor everywhere else.

I use this with the Park Chain Cleaner to regularly clean my chain.

I use the Park Tool chain scrubber to clean the chains on my bikes. The chain bride cleaner really cuts through the grime and it's environmentally safe. What more could ask for!?!

It's expensive, but then, they all are.

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.
