Fenwick's Foaming Chain Cleaner 200ml – Biodegradable, Solvent-Free Drivetrain Cleaner

Fenwick's Foaming Chain Cleaner 200ml is the compact, kit-bag-friendly format of Fenwick's biodegradable foaming chain cleaner — the same formula as the 500ml bottle, in a smaller size that's ideal for riders who want to carry it on trips, keep it in a kit bag, or try the product before committing to the larger format. At just 5–10ml per use, the 200ml bottle still provides up to 40 cleaning sessions — enough for a full season of regular maintenance for many cyclists.

The foam clings to the chain, cassette, jockey wheels, and chainset, penetrating and lifting grime before rinsing away cleanly — no chain bath required, no harsh chemicals, and no mess. The formula is completely free from solvents and acids, making it safe for anodised metals, carbon, plastics, rubber, and painted surfaces. For best results, pair it with the Fenwick's Chain Cleaning Sponge and Gear Cleaning Brush (both included in the Fenwick's Drivetrain Cleaning Kit) to clean all four sides of the chain and reach into cassette sprockets and derailleur jockey wheels. After cleaning, always re-lube the chain before riding — see the Fenwick's Professional Chain Lube or All Conditions Chain Lube.

For home workshop use where the larger format is more practical, the 500ml bottle offers better value per ml. Browse the full Fenwick's range or our workshop and maintenance collection.

What It's Good For

• Compact 200ml format — ideal for kit bags, travel, and trying the product before buying the 500ml
• Quick, integrated chain cleaning as part of a regular bike wash — no chain bath required
• 5–10ml per use — up to 40 cleaning sessions from a 200ml bottle
• Biodegradable, solvent-free and acid-free — safe on anodised metals, carbon, plastics, rubber, and painted surfaces
• Pairs with the Chain Cleaning Sponge and Gear Brush from the Drivetrain Cleaning Kit
• Road, gravel, MTB, and commuter drivetrains

What It's NOT Good For

• High-volume home workshop use — the 500ml bottle is better value per ml for regular use
• Chain lubrication — always re-lube after cleaning with a dedicated chain lube
• Heavily contaminated drivetrains requiring industrial-strength degreasing — multiple applications may be needed for very neglected chains

Frequently Asked Questions

What is the difference between the 200ml and 500ml formats?
The formula is identical — the only difference is the bottle size. The 200ml is more compact and portable, ideal for kit bags and travel. The 500ml is better value per ml and more practical for regular home workshop use. Both provide the same cleaning performance at 5–10ml per session.

How do I use the Foaming Chain Cleaner?
Apply 5–10ml of foam directly to the chain while backpedalling slowly, working around the full length of the chain. Allow the foam to dwell for a minute to penetrate and lift grime. Use the Chain Cleaning Sponge to clean all four sides of the chain, and the Gear Brush to clean the cassette and jockey wheels. Rinse thoroughly with clean water, allow to dry, then re-lube the chain before riding.

Do I need a chain bath to use this?
No — the foaming formula is designed to be applied directly to the chain on the bike, making a separate chain bath unnecessary for regular maintenance cleaning. This is what makes it so convenient to integrate into a standard bike wash routine.

Is it safe on carbon frames and anodised components?
Yes — the biodegradable, solvent-free and acid-free formula is safe for carbon fibre, anodised aluminium, plastics, rubber, and painted surfaces. It won't damage delicate finishes or strip protective coatings when used as directed.
