How to clean a bike: wash, dry and lube it properly

Short answer: how to clean a bike is seven steps in a fixed order: set up, rinse, degrease the drivetrain, wash the frame and wheels from the top down, wipe the brakes on their own, rinse and dry, then lube the chain. A bucket, a sponge, two brushes and a bottle of water do it in a hallway. Keep degreaser, chain lube and the drivetrain brush off disc rotors and pads, and never pressure wash bearings or an e-bike motor.

What to clean a bike with

The kit for cleaning a bicycle at home is a bucket of warm water, a bike cleaner or very diluted washing-up liquid, a sponge and a soft brush for the frame, a separate stiff brush and a degreaser for the drivetrain, three rags and a bottle of chain lube. A hose is optional.

Cycling UK's beginners' guide makes one rule of the brushes: the ones that touched the drivetrain do not go near the frame, or the grease goes with them.

Four kinds of product turn up on the shelf, and they do four different jobs:

• Bike cleaner, sold as bike wash. Muc-Off's instructions for its Bike Cleaner: rinse first, spray, leave three to five minutes, agitate stubborn grime and rinse thoroughly, never in direct sunlight or left to dry. Muc-Off states it is safe on rotors, pads, seals and carbon; Brompton still advises keeping bike wash off rotors, so finish them with alcohol.
• Degreaser. For the chain, cassette, chainrings and jockey wheels only. It dissolves old chain oil, which is why it must stay away from bearings, brakes and an e-bike's seals. Cycling UK's guide suggests a cycle-specific degreaser, and our chain cleaning guide covers how long to leave it.
• Isopropyl alcohol and disc brake cleaner. For the rotors. SRAM's brake service guide says to wipe a noisy rotor with isopropyl alcohol and a clean rag. Shimano's disc brake manual names isopropyl alcohol, soapy water or a dry cloth, and no commercial brake cleaners or silencing agents, which can damage seals. Alcohol on a rag is the common ground.
• Washing-up liquid. Cycling UK says soap or very diluted washing-up liquid works fine. Bosch's care advice for e-bikes accepts it as long as it is not aggressive or strongly degreasing. Brompton's guide notes that not all generic cleaning supplies are safe on components. Use a squirt in a bucket, never neat on the bike, and rinse it off fully.

Hair shampoo, car shampoo and kitchen sprays are not covered by any of these instructions, so we do not recommend them.

How to clean a bike step by step

How to wash a bike, in workshop order, is seven steps: set up, rinse, drivetrain, frame and wheels, brakes, rinse and dry, then lube and check. The dirty jobs come first so the grease is gone before the clean sponge goes on, the brakes are wiped on their own, and lube goes on last, onto a dry chain.

1. Set the bike up

Lean the bike against a wall, or put it in a workstand if you have one. Put cardboard or an old towel under both wheels indoors. Shift to a middle gear so the chain runs straight.

On an e-bike, switch the system off, take the battery out and remove the display, or cover a fixed display with a cloth. Bosch's care advice lists battery and display removal as the first step; Cycling UK adds switching the system off. Brompton says the same for the Brompton Electric: battery out before you start.

On a disc-brake bike, hang a plastic bag over each rotor while the degreaser is out. It takes ten seconds and keeps overspray off the pads.

2. Rinse the loose dirt off

Wet the whole bike with low-pressure water: a hose on a gentle setting, a watering can or a squeezed water bottle. Muc-Off's instructions start with a rinse before the cleaner goes on, so the cleaner works on the grime rather than on the mud sitting over it.

Let the water do the softening, because rubbing dry grit into the paint with a sponge scratches the finish. Keep the flow gentle and away from the hubs, the bottom bracket, the headset and any e-bike component. Bosch's advice is blunt about high pressure: water penetrates the bearings of the motor, the hubs and the rear frame.

3. Clean the drivetrain before the frame

Canyon's cleaning guide puts the drivetrain first, and that is the order used here. Spray or brush degreaser onto the chain, cassette, chainrings and both jockey wheels while you turn the cranks backwards. Scrub with the stiff brush, then rinse until the run-off is clear.

That is the short version. The clip-on tool, the bottle soak and the choice between wet lube, dry lube and wax are in our guide to cleaning a bike chain.

Two drivetrains skip the degreaser. A waxed chain is cleaned and re-waxed the way the wax maker says. A belt drive needs water only; the Gates Carbon Drive owner's manual says to wash it with water and never to lubricate it.

4. Wash the frame and wheels from the top down

Fill the bucket with warm water and a squirt of washing-up liquid, or spray the bike cleaner on. Start at the saddle and bars and work down, as Canyon's guide advises, so dirty water runs over parts you have not cleaned yet.

Use the sponge on the frame and fork, and the soft brush around the head tube, the bottom bracket shell and the cable stops. Handlebars, grips and saddle get the sponge and soapy water only.

Wheels take the soft brush: rim, spokes, hub shells, then the tyre. Brushing the tread shows up embedded glass and cuts before they become a puncture. On a rim-brake bike, wipe the braking track of the rim clean so the pads have something clean to grip.

5. Wipe the brakes on their own

Disc rotors and pads get their own step because degreaser, chain lube and the drivetrain sponge must not reach them. Shimano's manual warns that oil or grease on the rotor or pads may stop the brakes working, and names soapy water as safe. Brompton says bike wash contaminates rotors, and Bosch says keep chain lube off the disc.

Wipe each rotor with isopropyl alcohol on a clean rag until the rag comes away clean; SRAM gives the same wipe as its remedy for a contaminated rotor. Wipe the caliper body with the same rag and do not spray anything into the caliper.

If the brakes squeal or feel weak after a wash, the pads have picked something up. That is a diagnosis job, and our brake squeal guide walks through it.

6. Rinse and dry the bike

Rinse every trace of cleaner off with clean water. Muc-Off's instructions call for a thorough rinse, and dried-on cleaner leaves a residue that attracts dirt.

Bounce the bike on its wheels to shake water out, then dry it with a rag. Cycling UK's guide singles out the places that hold water: the drivetrain and the bolt heads. Add the brake calipers and the seatpost clamp.

Canyon's guide is clear that the bike should be fully dry before any lube goes on. In a flat, that means the bike stands on the cardboard until the chain and the bolt heads are dry to the touch, and only then goes back into the hallway.

Damp steel in a hallway is how rust starts, and salt from gritted roads speeds it up. Bosch's winter advice for e-bikes is to remove the salt after riding and let the bike dry well. If you find orange bloom while drying, our guide to removing rust from a bike covers what to do.

7. Lube the chain and check the bike

Put one drop of lube on each link of the chain while you turn the cranks slowly backwards. Cycling UK's guide and Brompton's give the same instruction: a drop per link, a few turns of the cranks, then wipe off the excess. Bosch adds a placement rule for e-bikes: apply lube where the chain runs freely, away from the disc.

Before you ride, squeeze both brake levers hard. On an e-bike, run Bosch's function check: battery engaged, drive working, buttons responding. Check the tyres against our tyre pressure guide while the pump is out.

How to clean a bike without a hose

The best way to clean a bike without a hose is a bucket, a bowl and a squeezed water bottle, in a hallway or on a balcony. Brompton's guide says a bucket of hot water and a sponge do the job as well as a hose.

The hallway method:

• Lay cardboard or an old towel under both wheels, wider than the bike, and open a window.
• Knock the dry mud off outside first. Bang the tyres on the pavement and brush the worst off the frame at the kerb, so it never comes indoors.
• Fill a bucket with warm water and a squirt of washing-up liquid, and a bowl with clean water for rinsing.
• Degrease the chain from the brush. Spray degreaser onto the stiff brush, then work it into the chain and cassette. Nothing lands on the floor or the rotor.
• Rinse the drivetrain from a squeezed bottle held close, catching the run-off with a rag underneath.
• Sponge the frame and wheels from the top down, rinsing the sponge in the bucket. Change the water when it turns grey.
• Wipe with a cloth wrung out in clean water to lift the soap off, then dry with a third rag.
• Wipe the rotors with alcohol, lube the chain, and leave the bike to dry on the cardboard before it goes back against the wall.

A bike cleaner spray suits this method, because Muc-Off's instructions only ask for a rinse, and a rinse from a bottle counts. Use small amounts of everything: degreaser sludge on a laminate floor is harder to clean than the bike.

A light wipe-down after a wet commute is a different job. Run a damp cloth over the frame and a dry rag through the chain, add a drop of lube, and the bike is done in a few minutes at the door.

Can you pressure wash a bike?

No, not if you want the bearings to last. Cycling UK's guide says never to use a pressure washer, and Bosch's care advice calls high-pressure cleaning of an e-bike's components a no-go because water gets into the bearings of the motor, hubs and rear frame.

Canyon's guide adds the other problem: a high-pressure hose forces dirt into the crevices. Brompton's guide allows a hose only on a low-pressure stream.

The problem is the force of the water rather than the water itself. A gentle stream wets the bike and carries dirt away. A jet drives water past the seals on the hubs, bottom bracket, headset and suspension pivots, where it washes the grease out. The jet lance at a car wash is the same thing under a different name.

How often should you clean a bike?

Clean the bike when it is dirty, and on a schedule in between. The published figures come from two sources:

• Cycling UK: road riders every 160 km and more often in winter; occasional riders once a month; off-road and gravel riders every couple of weeks and after every particularly muddy ride.
• Canyon: a commuter on a hybrid in dry conditions may be fine with once a week; a mountain or gravel bike after every muddy ride; a road bike's drivetrain cleaned and lubricated about every few hundred kilometres.
• Bosch, for e-bikes: ideally after every trip, so dirt does not become engrained, with salt removed after winter rides.

A London commute in winter sits at the dirty end of those figures. A rinse and wipe after a gritted ride, and a full wash at the weekend, keeps the chain silver.
