Muc-Off's "Bio Drive Train Cleaner" is the answer for all dirty, sticky, and smeared drive units! It is simply sprayed onto the chain, derailleur, sprockets, and gears. Then, let the drive cleaner work for 3-5 minutes. For stubborn dirt, it's best to use the Detailing and Claw Brush and then simply rinse off. It is biodegradable and therefore harmless to the environment. It can be used in combination with the "X3 Chain Cleaning Device" by filling the drive cleaner into the designated reservoir.
