Park Tool CB-4 - Bio Chainbrite 4 Cleaner: 16 oz / 475 ml (Single)

Works a treat. Accidentally let mine get cold - it turns into soup! Don't do that

Good cleaner - really effective when used with the Park Tools Chain Cleaning machine.

Seems to do its job as a chain cleaner with a cleaning cassette. It does solidify in cold temps so keep it inside.

Used this to clean my bikes chains using the Park Tools chain cleaner. Was very pleased with how it performed. My chains look as good as new. Would definitely recommend using with the chain cleaning tool as leaves less mess. Very easy to use and cleaned the chain in just a few minutes.

Does a great job with the Park tool chain cleaner, takes less than 10 mins to clean the chain prior to re lubrication

The park tool CB for chain Cleaner is the perfect companion to the park tool chain cleaning accessory. You pour it into the top of the device put it onto the chain and then click the top element over and then run the chain through the device to clean all of the gunk and grease off. This is highly effective as an alternative to a more harsh mechanical degreaser and would highly recommend it for regular use of cleaning your bike chain and keeping it running smoothly.

Very easy and quick for cleaning your chain

tends to glump up within 4 weeks of opening the first time (stored in a dry environment) so I would only get it if you will be using it frequently, its cleaning power is superb however and its a fairly decent value for money, but the bottle can sometimes leak

I've been using Park Tool CB-4 for years to keep my drivetrain clean. Regular use of this product is one of the most effective ways to maintain efficiency and extend the lifespan of my bike’s drivetrain and other high-end components with less friction, resulting in smoother shifting and more time in the saddle. Is there anything better than that? Pros 100% biodegradable, natural, plant-based degreaser Easy to clean up after a full drive-train cleanup with Park Tool CM 5.3 Cyclone No harsh smells Cons Price
