Muc-Off Bio Degreaser 500ml – Water‑Soluble Bike Chain Cleaner, Rinseable & Biodegradable

Muc-Off Bio Degreaser is a 500ml, water-soluble bicycle degreaser formulated to dissolve oil, grease and wax residue from chains, gears and components while rinsing away easily.

Designed by Muc-Off’s R&D team for cyclists who need a powerful yet rinseable cleaner, this biodegradable-content degreaser targets persistent lubrication and grime on metal, plastic and rubber parts. It removes built-up waterproof greases and chain waxes without leaving a sticky film, and it’s suitable for both whole-bike maintenance and focused chain cleaning. Because the formulation is water-soluble, excess product washes away with water for straightforward cleanup after scrubbing.

How does this degreaser get grease and chain lube off my bike?

The formula breaks down grease, oily lubricants and wax residues, loosening them from surfaces so they can be brushed and rinsed away. It’s formulated to penetrate into links and cogs, reducing the effort needed to restore moving parts to a clean condition.

• High-performance solvent action on waterproof greases and wax
• Penetrates chain links and gear teeth for deep cleaning
• Rinseable with water to remove dissolved grime
• Works on metal, plastic, rubber and seals without leaving residue

Can I use it on every part of my bike and chain?

Yes — the degreaser is intended for chains, derailleurs, cassettes, chainrings, and individual components such as bolts and bearings housings (external). It cleans metal, plastic and rubber surfaces, but avoid prolonged contact with sensitive finishes and always follow by a rinse and appropriate lubrication where required.

• Safe for drivetrain parts: chain, cassette, chainrings, jockey wheels
• Effective on component housings, bolts and metal fittings
• Acceptable for plastic and rubber parts when rinsed promptly
• Not a protective treatment — re-lube moving parts after cleaning

How do I use the 500ml bottle for the best results?

Apply sparingly to targeted areas or use with a chain-cleaning tool, agitate with a brush, then rinse thoroughly with water. For heavily soiled chains, repeat the process and finish by drying the drivetrain and applying fresh lubricant to protect against corrosion and wear.

• Spray or pour onto chain and gears; allow a short dwell time to break down grime
• Brush or use a chain-cleaner tool to agitate loosened residues
• Rinse with water until runoff is clear, then dry components fully
• Apply appropriate chain lubricant after cleaning to restore protection

Is this product environmentally conscious and safe to rinse away?

The contents are formulated to be biodegradable, meaning the active cleaning agents break down more readily than many traditional solvents. Because the product is water-soluble it’s designed to be rinsed away, though local disposal rules vary, so avoid releasing concentrate into sensitive waterways and follow local guidance when cleaning outdoors.

• Biodegradable contents to reduce long-term environmental persistence
• Water-soluble for easier rinsing from parts and tools
• Best used with sensible runoff management near drainage
• Follow local regulations for chemical disposal and environmental care

Who is this for: Cyclists and bike mechanics who want a reliable, rinseable degreaser for routine maintenance and heavy grime removal. It’s suited to recreational riders, commuters, and workshop users who need a versatile cleaner for chains, drivetrains and component parts — just remember to dry and re-lubricate moving components after cleaning.
