The Muc-Off X-3 Dirty Chain Machine is a clip on chain cleaning tool with rotating brush wheels and abrasive teeth. It comes with a refillable 2.5 fl oz bottle of Muc-Off Drivetrain Cleaner.

What it's for

A chain cleaner lets you degrease the chain while it stays on the bike. You clip the machine around the chain, backpedal, and the brushes scrub each link as it passes through. Muc-Off says it removes grease, grime, and chain oil in seconds.

How it works

Contact points: rotating brush wheels and abrasive teeth give 120 points of contact on the chain

Top button: press the button on top to release cleaner onto the chain as you turn the pedals

Reusable: the machine opens up for cleaning and can be refilled and used again

Compatibility

• Fits: road, mountain bike, and cyclocross chains
• Does not fit: BMX chains, track chains, or motorcycle chains, because their links are wider

Setup and installation

• Step 1: spray the dirty drivetrain area with Drivetrain Cleaner
• Step 2: scrub with a Claw Brush
• Step 3: fill the machine's reservoir with cleaner
• Step 4: place the machine over the chain and clip it shut
• Step 5: turn the pedals backward 2 to 3 times
• Step 6: press the top button to release cleaner while you keep turning the pedals
• Step 7: take the machine off the chain
• Step 8: rinse the whole drivetrain with water
