Before you startGeneral guidance from our members' experience, checked against the sources listed at the foot of this page. Old bicycles vary, so check everything against your own bike. Brakes, steering, wheels and tyres are safety-critical: if you're not sure, have a qualified mechanic do or check the work. Any work you do is at your own risk. See our terms.
Too aggressive on light rust, or too gentle on heavy rust, wastes time and can do damage. Work out how bad it is first, then follow that method.
Light: discolouration, no pitting
- Dry wipeRemove loose debris with a dry cloth.
- Foil method on chromeSee Cleaning chrome, which has before and after photos of a lamp set done this way.
- Wipe cleanRemove all the dark residue with a microfibre cloth.
- Protect it the same dayWax or a light oil.
Moderate: rust patches, pitting starting (steel parts only)
- Soak small steel parts in white vinegarCheck them every hour or so; one to four hours is usually enough. Don't use vinegar on aluminium.
- Scrub with a brass brushBrass is softer than steel, so it won't gouge the part.
- NeutraliseRinse in a solution of bicarbonate of soda, then in clean water.
- Dry completelyWarm air, so no moisture is left.
- Protect it straight awayOil or wax. Bare steel can rust again quickly in damp air.
Severe: deep pitting, flaking, rust that may be structural
- Assess it firstIf a part that takes load is badly pitted, replace it. Don't ride it.
- Soak in a rust removerEvapo-Rust's maker says it's water-based and non-toxic, won't affect plastic, rubber or non-oxide paints, and won't harm unrusted steel. Jenolite Rust Remover is another option; Jenolite says it leaves the metal ready for priming.
- Or convert itJenolite Rust Converter chemically turns rust into a stable base that most paints can go straight onto, according to Jenolite. It suits frames you're going to repaint.
- Rinse and follow the instructionsEach product is different, so follow its own directions.
- Prime bare steel promptlyIf you're repainting, don't leave bare metal exposed.
Don't useSteel wool near chrome or alloy; bleach or caustic cleaners; an angle grinder on thin tubing; vinegar on aluminium; a rust converter on chrome or aluminium without checking (Jenolite advises a compatibility check on those metals); a pressure washer near bearings.
Rust inside tubesYou can't see it until it's too late. If you suspect a frame is rusting from inside, don't ride it until someone experienced has checked it.
