Muc-Off Bio Degreaser bike cleaner 500 ml — biodegradable, water-soluble formula for chains & drivetrains

This concentrated degreaser from Muc-Off is designed for cyclists who need a fast, effective way to cut through stubborn lubrication and grime without leaving harmful residues. Its water-soluble formula rinses away cleanly and is formulated to work on metal, plastic, rubber and seals. While only the product contents are biodegradable, the cleaner is engineered to loosen heavy grease, chain lube and wax so you can restore drivetrain performance and component longevity.

How quickly does it remove grease and chain lube?

The Bio Degreaser is a fast-acting formula that penetrates and lifts grease and wax in minutes. You’ll notice visible breakdown of grime on contact, making brushing and rinsing far easier than with plain detergent.

• Works in minutes on heavy grease and waterproof lubricants
• Breaks down chain wax and lube residue for thorough cleaning
• Pairs with brushes and a chain-cleaning tool for faster results
• Rinses away with water, leaving less greasy residue

Can I use it on all bike parts safely?

Muc-Off Bio Degreaser is safe on most bicycle materials including metal, hard plastics, rubbers and seals when used as directed. Avoid prolonged contact with painted surfaces—rinse promptly—and test in a hidden area if you’re unsure about delicate finishes.

• Suitable for chains, cassettes, chainrings, derailleurs and bearings (when rinsed)
• Works on plastic and rubber components without immediate damage
• Not intended for prolonged exposure to painted surfaces—rinse after application
• Follow manufacturer guidelines for suspension seals and sensitive parts

How do I use it for best results on my drivetrain?

Spray liberally onto the drivetrain and allow a short dwell time to loosen grime, then agitate with a brush or chain-cleaner before rinsing. For heavily soiled chains, repeat the process or use a dedicated chain-cleaning device for a deeper clean.

• Spray directly on chain, cassette and chainrings; wait 1–3 minutes
• Use a stiff brush or chain scrubber to agitate and lift debris
• Rinse thoroughly with water until runoff is clear
• Dry chain and relubricate with your chosen chain lube

Is it environmentally friendly and how should I dispose of runoff?

The contents are biodegradable and designed to break down more readily than many solvent-based degreasers, but proper disposal is still important. Rinse runoff into a drain with plenty of water where permitted, and avoid releasing concentrated product into natural water bodies.

• Formula is biodegradable (contents only) for reduced environmental impact
• Dilute rinses with plenty of water before disposal where local rules allow
• Avoid directing concentrated runoff straight into rivers or streams
• Check local regulations for washing solvents and chemicals

Who is this for: Muc-Off Bio Degreaser 500 ml suits everyday riders, mechanics and competitive cyclists who need a reliable, fast-acting cleaner that handles heavy chain grease, wax and lube residues. It belongs in any bike-cleaning kit for people who want effective degreasing with easier rinse-off, whether you’re preparing a bike for maintenance, race day service or regular weekly cleaning.
