Park Tool CB-4 is a 100% biodegradable 100% vegetable-based 100% degreaser designed for use with chain cleaners, such as cyclone chain scrubber cm-5.3, professional chain scrubber cm-25 or with an abrasive brush as an degreaser for general use. If used with a chain cleaner, CB-4 cleans the bicycle chains inside and outside, so they are like new. It does not damage the parts in alloy, plastic, rubber or carbon fiber, so it is safe to use to clean cassettes, crowns, pulleys or any other component that accumulates mud and dirt.
