Chain cleaner Muc-Off BIO 400 ml with washer – bike chain cleaning kit, biodegradable 400 ml

Muc-Off BIO 400 ml chain cleaner with washer is a bike chain cleaning kit that pairs a 400 ml biodegradable cleaning fluid with a dedicated chain washer tool. The kit is formulated to dissolve and lift dirt, grease and grime from drivetrain chains while minimising environmental impact. Designed for routine home maintenance and quick pre-ride cleaning, the combination of fluid and washer helps maintain smooth shifting and can reduce accelerated wear on sprockets and rollers.

Advantages

The biodegradable cleaning fluid effectively breaks down oil and road grime without leaving heavy residues, and the washer tool provides targeted mechanical agitation to dislodge embedded contaminants. The compact 400 ml bottle is sized for multiple servicing sessions and the washer attaches securely to standard bicycle chains for controlled cleaning. The kit supports safer chain care by reducing the need for harsh solvents and simplifying the cleaning process into a single, reusable tool plus refillable fluid.

Suitable for

• Routine home bicycle drivetrain cleaning
• Pre-ride chain maintenance to improve shifting
• Cleaning chains on road, gravel, hybrid and mountain bikes
• Users seeking a biodegradable alternative to solvent-based cleaners

How to use

Secure the chain washer onto the bicycle chain according to the tool’s instructions, ensuring the chain is stationary and the bike is supported. Fill the washer’s reservoir with the 400 ml cleaning fluid or apply the fluid as directed, then rotate the cranks slowly to run the chain through the washer so brushes and internal pads agitate and remove contaminants. After several rotations, remove the washer and rinse the chain with clean water or wipe thoroughly with a dry cloth. Allow the chain to dry before applying a suitable lubricant.

Usage recommendations

Use the Muc-Off BIO 400 ml kit regularly to prevent heavy buildup; avoid prolonged contact with painted surfaces and store the fluid in a cool, dry place. After cleaning, always apply chain lubricant appropriate for your riding conditions to protect against corrosion and wear.
