How to clean a bike chain

A short, no-nonsense walkthrough — the steps, the gotchas, and answers to the usual questions.

20 minutes Easy

A clean, lubricated chain shifts smoothly, wears more slowly, and saves you money on replacement parts. Grit stuck in old lube grinds down the chain and gears, so a regular clean is one of the best things you can do for a bike. Here is a straightforward degrease-and-relube.

What you'll need

  • Degreaser or dish soap
  • A stiff brush or old toothbrush
  • Clean rags
  • Bike chain lube
  • Optional: a chain-cleaning tool
  • Gloves

Step by step

  1. Set the bike upPut the bike in a stand or lean it securely, and shift to a middle gear so you can turn the pedals freely by hand.
  2. Apply degreaserCoat the chain with degreaser or soapy water while slowly backpedaling so every link gets covered, and let it sit a couple of minutes.
  3. Scrub the chainWork a stiff brush over the links, top and bottom, and clean the front chainrings and rear cogs where gunk builds up.
  4. Rinse and dry fullyRinse with a little water, then wipe the chain dry with a clean rag while backpedaling until no dirty residue shows and the chain is fully dry.
  5. Re-lube the chainDrip one drop of lube onto each roller while backpedaling, let it soak in for a minute, then wipe off all the excess from the outside.

Handy tips

  • Wipe off excess lube well, since a wet, shiny chain attracts dirt and forms grinding paste.
  • Use a wet lube for rainy conditions and a dry lube for dusty, dry riding.
  • Lube the chain, not the gears or brakes, and keep lube off the rims and rotors.

Heads up

  • Keep degreaser and lube away from disc brake rotors and pads; contamination ruins braking and can be dangerous.

FAQ

How often should I clean my chain?

Roughly every few hundred miles, or whenever it looks dirty or sounds noisy. Wet or muddy rides call for more frequent cleaning.

Can I use WD-40 to lube my chain?

Standard WD-40 is a light solvent, not a lasting chain lube, so it can help clean but should be followed with a proper bike chain lube.

Do I have to remove the chain to clean it?

No. For a routine clean you can leave it on and use a brush or a clip-on cleaning tool while turning the pedals.
