The Muc-Off X-3 Dirty Chain Machine is the easiest way to give your chain a thorough clean. This innovative tool comes with a 75ml bottle of Muc-Off Drivetrain Cleaner, which can be sprayed directly onto the drivetrain or poured into the machine&&';;s top reservoir. The control button releases the cleaner as abrasive cleaning teeth and rotating brush wheels with 120 contact points scrub every area of your chain links, ensuring a deep and efficient clean. Excess grime is captured in a separate lower reservoir, keeping your chain free from recycled dirt. Muc-Off Drivetrain Cleaner is biodegradable and safe for disposal, especially if you&&';;ve used one of our bio chain lubes.
