Soaps, Degreasers and Sprays: What Makers Say to Use and Avoid

The frame is dull, the chain is black, and there's a shelf of cleaners in the garage. Which of them can go near an e-bike?

Makers lean toward mild. Here's how they sort it.

Symptom: general grime on the frame and plastics

Use a bike-specific soap. If you don't have one, one maker says a little dish soap will work fine.¹ Another says biodegradable bike shampoos are kind to the many protective seals on the bike's components.²

That second point is worth holding onto. Another maker also says to pick mild soaps without harsh chemicals or solvents, since these can damage plastic parts and electrical seals.³

Symptom: you reached for car wash soap

Put it back. One maker says not to use harsh chemicals, cleaners or heavy degreasing soaps like car wash.¹ Another says most car soaps contain wax that isn't suitable for e-bikes.³

Symptom: greasy chain and gears

One maker advises being careful not to get degreaser on any braking surfaces.² Another guide says to avoid degreasers on painted surfaces and to apply them carefully on drivetrain components.³

Don't use a jet. See the pressure washer page.

Symptom: soap in places it shouldn't be

One maker says a little soap might be hard to avoid near the bottom bracket, headset bearing and seat post. Too much in these areas can damage the frame or make certain parts squeak.¹ Try not to scrub those spots.

How much soap to use

Not much. One maker's guide says soap isn't necessary for cleaning an e-bike. If you want it, a light amount of dish soap in the water will do.³ A bucket of lightly soapy water for washing and a second bucket of plain water for rinsing is the setup that guide describes.³

For rinsing, follow your manual.

Brakes

One guide advises dedicated disc brake cleaner on disc brakes to maintain braking performance.³ If your brakes feel different after washing, read your manual, or ask the maker or a bike shop.

Sprays and solvents

Makers do recommend bike-specific degreaser for the drivetrain. Canyon says biodegradable bike degreasers are kind to the many protective seals.² Velotric and Ariel Rider both name bike-specific degreaser too.¹⁴ None of the saved pages approves a general-purpose spray or solvent for the frame, plastics or seals. Velotric says harsh chemicals are too harsh for an e-bike.¹ And a water-resistance rating doesn't promise protection against other fluids such as oils or solvents.⁵

So read your manual's list of approved and banned products. If it lists none, stay with mild soap and water.

A short guide

• Frame and plastics: bike soap or a little dish soap.¹
• Chain and gears: bike degreaser, kept off braking surfaces.²
• Disc brakes: HOVSCO advises dedicated brake cleaner.³
• Avoid: car wash soap and harsh chemicals.¹

After rinsing, move on to drying.
