Muc-Off X-3 Dirty Chain Cleaner Machine Cleaning a greasy and grimy chain can be a tedious and arduous task. Well, Muc-Off has the solution with its X-3 Chain Cleaner Machine. The machine combines an all-encompassing deep clean with the deep-cleansing Drivetrain Cleaner for a quick and easy means of getting your chain running smoothly. Included are both the cleaning machine as well as a 75ml measure of Muc-Off Drivetrain Cleaner. This liquid can be either sprayed directly onto the drivetrain or poured into the top of the reservoir of the X-3 machine and then released with the nifty control button. Muc-Off's Drivetrain Cleaner partners up with the X-3 Machine to cut through the worst of your chain's grease and grime. Inside, the X-3 abrasive cleaning teeth alongside a rotating brush wheel provide 120 contact points that cover all of the chain's surface area for a deep and thorough clean. Dirty fluid is kept from being recycled over the chain by dropping into a lower reservoir level where it is kept away from your shiny clean chain. On top of all of this cleaning prowess, Muc-Off Drivetrain Cleaner is fully biodegradable so you can rest assured that your rejuvenated chain does not come at the expense of the environment.
