Fenwick's Drivetrain Cleaning Kit – Foaming Chain Cleaner, Chain Sponge & Gear Brush

Fenwick's Drivetrain Cleaning Kit is a three-piece bundle designed specifically for cleaning the chain, cassette, derailleur, and chainset — the parts of the bike that accumulate the most grime and have the greatest impact on shifting performance and component longevity. The kit contains a Foaming Chain Cleaner, a Chain Cleaning Sponge, and a long-handled Gear Cleaning Brush — everything you need to clean the drivetrain thoroughly without resorting to harsh chemicals or making a mess.

The Foaming Chain Cleaner is the standout product: a biodegradable formula that is completely free from solvents and acids, yet powerful enough to cut through stubborn drivetrain grime with minimal product usage. The foam clings to the chain and cassette, penetrating and lifting dirt before rinsing away cleanly — safe for the environment, safe for your bike's finish, and effective on even heavily soiled drivetrains. The Chain Cleaning Sponge is designed to clean all four sides of the chain simultaneously without causing damage to the links or plates — a more thorough and efficient method than wiping with a rag. The long-handled Gear Cleaning Brush features dual-stiffness bristles that reach into the tight spaces between cassette sprockets, around derailleur jockey wheels, and into chainset teeth where a standard brush can't reach.

Used together, the three tools make drivetrain cleaning faster, more thorough, and less messy than improvised methods. After cleaning, re-lube the chain with a dedicated chain lube — see the Fenwick's Professional Chain Lube or the All Conditions Chain Lube.

What's Included

• Foaming Chain Cleaner — biodegradable, solvent-free and acid-free foam formula for chain and cassette cleaning
• Chain Cleaning Sponge — cleans all four sides of the chain simultaneously without damage
• Long-handled Gear Cleaning Brush — dual-stiffness bristles for cassettes, derailleurs, and chainsets

What It's Good For

• Thorough drivetrain cleaning — chain, cassette, derailleur jockey wheels, and chainset
• Biodegradable, solvent-free and acid-free Foaming Chain Cleaner — safe for bike and environment
• Chain Cleaning Sponge cleans all four sides of the chain simultaneously
• Long-handled brush reaches tight spaces between cassette sprockets and around derailleur pivots
• Compact kit that fits neatly in a workshop drawer or toolbox
• Road, gravel, MTB, and commuter drivetrains

What It's NOT Good For

• Frame washing — use a dedicated bike cleaner for the frame and components outside the drivetrain
• Chain lubrication — the kit cleans but does not include chain lube; re-lube after cleaning with the Fenwick's Chain Lube
• Industrial-strength degreasing with harsh solvents — the foaming cleaner is biodegradable and solvent-free; for extremely neglected drivetrains, multiple applications may be needed

Frequently Asked Questions

Do I need to buy chain lube separately?
Yes — this kit cleans the drivetrain but does not include chain lube. After cleaning, always re-lube the chain before riding. See the Fenwick's Professional Chain Lube or All Conditions Chain Lube for compatible options, or the Fenwick's Essential Cleaning & Lubrication Kit which includes both cleaner and chain lube in one bundle.

Is the Foaming Chain Cleaner safe on all drivetrains?
Yes — the biodegradable, solvent-free and acid-free formula is safe for all chain types, cassettes, chainrings, and derailleur components across road, gravel, MTB, and commuter drivetrains. It won't damage seals, anodised surfaces, or carbon components.

How do I use the Chain Cleaning Sponge?
Apply the Foaming Chain Cleaner to the chain, then run the chain through the sponge while backpedalling. The sponge's design cleans all four sides of the chain — inner plates, outer plates, rollers, and pins — simultaneously. Rinse with water and allow to dry before applying fresh chain lube.

How often should I clean my drivetrain?
Clean after every wet or muddy ride, and every 2–4 weeks in dry conditions. Visible grit on the chain and cassette, or a dry/squeaky chain sound, are signs it's time for a clean and re-lube. Regular cleaning significantly extends the life of your chain, cassette, and chainrings.
