Whether for transportation or exploration, cycling is an inherently environmentally-friendly discipline. Park Tool takes that logical next step with the formulation of CB-4 Bio ChainBrite Cleaner, a 100% biodegradable, natural, plant-based degreaser to freshen-up your chain and components.

Park's CB-4 Bio Chainbrite Cleaner is engineered to be used at full strength (no diluting with water) in conjunction with the Park Tool CM-5.2 Cyclone Chain Scrubber or as a general purpose degreaser. Chainbrite can be used liberally as it won't harm alloy, plastic, or rubber parts.

Features:

  • Size: 16 oz bottle
  • 100% biodegradable, natural, plant-based degreaser
  • Use CB-4 full strength, do not dilute with water
  • Not harmful to alloy, plastic, or rubber parts

Effective

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.

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.

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.

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.

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.
