Muc-Off X-3 Dirty Chain Machine Cleaning Kit. The X-3 Dirty Chain Machine is by far the easiest way to give your chain a good scrub. Included in the kit is a 75ml measure of Muc-Off Drivetrain Cleaner. This revolutionary little liquid can be either sprayed over the drivetrain or poured directly into the top reservoir of the machine which is then released by a control button. The abrasive cleaning teeth and rotating brush wheels which have 120 contact points cover all areas of the individual chain link for a deep and thorough clean. Finally the excess dirty fluid drops into a second lower reservoir so it’s kept away from the clean chain. No more recycled grime all over the chain. Muc-Off Drivetrain Cleaner is fully biodegradable and is safe to be disposed of down the drain if you previously used one of our bio chain lubes.Easily removes grease grime and chain oil in secondsDeepest clean thanks to 120 contact pointsEasy to clean and re-useHeavy duty construction thats built to lastIncludes 75ml Muc-Off Drivetrain CleanerPerfect for Road MTB or Cyclocross bicycle chainsThe X-3 Dirty Chain Machine is not compatible with BMX or track chains
