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

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 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.

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

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

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

Works great with Park Chain Cleaner

To clean almost anything

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 used this with my chain cleaner to clean my chain on my new mtn bike and my new gravel bike. works well.

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

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

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 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.

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.

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.
