The best way to clean nylon dog leash gear is a soak in water with a little dog shampoo, a scrub of the dirty spots, a thorough rinse and air drying. The AKC leash guide calls that the safest way to wash a nylon leash. It uses hot water, while the AKC harness guide suggests warm water with a mild detergent for nylon harnesses, so this guide notes both. Machine washing is only an option when the manufacturer’s tag says so. Leather leashes need a different approach, and the AKC does not recommend soaking them.

Quick answer

  • Wash the leash when it gets dirty or smelly. The AKC leash guide says leashes need washing eventually.
  • The safest method the AKC leash guide describes: hot water with a little dog shampoo, a soak, a scrub of dirty spots, a rinse and air drying.
  • Use the machine only if the manufacturer’s tag says a machine wash is allowed. In that case, the AKC leash guide suggests a mesh laundry bag.
  • Do not soak a leather leash. Wipe it with a damp, soft sponge instead.
  • If you use a leather cream on a leash, use one that is safe for dogs. The AKC leash guide says so directly.

Why nylon leashes need washing

The AKC leash guide says leashes get dirty and smelly and eventually need to be washed. That is the reason to add a leash to your cleaning routine, rather than waiting until it looks worn. The guide does not say how often that should happen.

Step 1: Check the tag

Before you wash, check the manufacturer’s tag or care label. The AKC leash guide says that some nylon leashes can go in a mesh laundry bag and into the washing machine, but only if the manufacturer’s tag says so. If the tag does not allow machine washing, use hand washing.

If the tag is missing or unreadable, use the hand-washing method below. The AKC leash guide describes hand washing as the safest way to wash a nylon leash.

How to wash a nylon leash by hand

The AKC leash guide describes the safest way to wash nylon leashes in four steps:

  1. Fill a bowl with hot water and add a little dog shampoo.
  2. Soak the leash in the water.
  3. Scrub off any especially dirty spots.
  4. Rinse the leash thoroughly, then air dry it.

The sources do not describe a specific brush or a soak time, so use what you have on hand and keep the scrubbing to the dirty spots.

Hot water or warm water

The AKC leash guide says hot water with dog shampoo is the safest way to wash a nylon leash. The AKC harness guide gives a different method for nylon and neoprene harnesses: a mild detergent of the kind used for handwashing clothing, diluted in warm water, followed by soaking, rinsing and air drying. Both guides describe a soak, a rinse and air drying, so the core steps match.

The two guides do not agree on the water temperature, and they are about different products. This guide follows the leash guide for leashes, because that is the item the page covers. If the leash has a care label that names a temperature, follow the label. The sources we opened do not say whether hot water causes problems for any specific nylon weave, so this guide does not make that claim.

Machine washing

Some nylon leashes can go into the washing machine. The AKC leash guide describes a mesh laundry bag for that step, and it says machine washing is only appropriate when the manufacturer’s tag allows it. Check the tag first, every time.

Retractable leashes with nylon cords

Retractable leashes are a common type with nylon. The AKC leash guide says a retractable leash contains a nylon tape or cord that extends and retracts. The guide does not give a separate cleaning method for the retractable cord, the housing or the handle. If you have a retractable leash, check the manufacturer’s instructions for the housing before you soak it. The sources we opened do not say whether the nylon method is safe for the cord.

Leash materials at a glance

The AKC leash guide and the AKC harness guide describe several methods. The table below sets out only what those pages state, so you can see where the guidance is clear and where it stops.

Material Cleaning method the sources state Machine washing Notes from the sources
Nylon leash Hot water with a little dog shampoo, soak, scrub dirty spots, rinse, air dry Only if the manufacturer’s tag allows it, in a mesh laundry bag Described as the safest way to wash nylon leashes
Nylon harness Mild detergent for handwashing clothing, diluted in warm water, soak, rinse, air dry Not stated Harness guide, not a leash method
Leather leash Wipe with a damp, soft sponge; do not soak Not stated Leather does not benefit from a water bath
Chain leash Not stated Not stated The leash guide describes the handle and chain but not a cleaning method

The table makes one point clear. The leash guide is the only one of the two that gives a nylon leash method in full, and it gives a temperature and a shampoo. The harness guide gives a detergent and warm water. Both describe the same soak, rinse and air-dry sequence.

Inspect the leash while you clean

Cleaning is a good time to check the leash. The AKC harness guide advises checking hardware for cracks, and it advises looking for areas where the fabric may be frayed or damaged. The sources we opened do not describe these checks for leashes specifically, so treat the advice as a reasonable extension of the harness guidance rather than a leash-specific rule.

Run your hand along the nylon webbing and look for fraying, thin spots or stitching that has pulled loose. Check the clip and any ring for cracks. If you find damage, note it before you wash the leash. The sources do not say when a leash is too worn to keep using, so this guide does not give a cutoff.

Leather and other leash materials

The AKC leash guide says leather does not benefit from a water bath. If your leash is leather, wipe dirt off with a damp, soft sponge. The guide says you can soften leather with a leather cream, but the cream must be safe for dogs.

The AKC collar guide warns against leather cleaners made for furniture or shoes, because the chemicals can be toxic for dogs. Use only the dog-safe option, and do not use furniture or shoe products on a leash.

Chain leashes have a nylon or leather handle and a chain. The AKC leash guide describes the chain and the handle as separate parts, but it does not give a cleaning method for chain leashes, so this guide does not give one.

Drying the leash

The AKC leash guide says to air dry a nylon leash after rinsing. The guide does not give a drying time, so this guide gives none. Lay the leash out so it dries completely before you use it again.

Common mistakes

  • Washing a nylon leash in the machine without checking the tag. The AKC leash guide says machine washing applies only when the manufacturer’s tag allows it.
  • Skipping the rinse. Rinse the leash thoroughly after the soak.
  • Soaking a leather leash. The AKC leash guide says leather does not benefit from a water bath.
  • Using a furniture or shoe cleaner on a leather leash. The AKC collar guide warns against those chemicals because they can be toxic for dogs.
  • Putting a damp leash away. Let it air dry completely first.
  • Cleaning a retractable leash the same way as a fixed nylon leash without checking the housing instructions.

How we chose

We opened three independent AKC pages on 2026-10-23: the leash guide, the harness guide and the collar guide. We read the text of each page and checked every quoted sentence against the page text before using it. We did not use product listings, leash brand pages or retailer guides as sources. This guide does not recommend any leash.

What we could not verify

  • The sources we opened do not say whether hot water shortens the life of a nylon leash. This guide follows the leash guide’s method and does not claim more than that.
  • The sources do not give a drying time for nylon.
  • The sources do not describe how to clean the clip or the metal hardware on a leash.
  • The sources do not give a cleaning method for retractable leash housings or handles.
  • The sources do not say how often to wash a leash beyond the general rule that leashes eventually need washing.
  • The sources do not say whether a specific leash is machine washable. Only the manufacturer’s tag can answer that for a given leash.

FAQ

How often should I wash a nylon dog leash?

It does not give a schedule. Wash the leash when it looks dirty or smells, and check it during regular grooming.

Can I put a nylon dog leash in the washing machine?

Only if the manufacturer’s tag says so. The AKC leash guide suggests a mesh laundry bag for leashes that are machine washable. Without that instruction, hand wash it.

What is the safest way to wash a nylon leash?

The AKC leash guide describes hot water with a little dog shampoo, a soak, a scrub of any dirty spots, a thorough rinse and air drying.

Can I use warm water instead of hot water?

The AKC harness guide uses warm water with a mild detergent for nylon harnesses. The sources do not say whether hot water is necessary for a leash. Follow the care label if it names a temperature.

How do I clean a leather leash?

Do not soak it. The AKC leash guide says to wipe it with a damp, soft sponge and, if you use a conditioner, to use a leather cream that is safe for dogs.

Can I wash a retractable leash the same way?

The sources we opened do not give a cleaning method for retractable leash housings. Check the manufacturer’s instructions for the housing, and use the nylon method on the cord or tape only if the manufacturer allows it.

Bottom line

For a nylon leash, the AKC method is a soak in hot water with a little dog shampoo, a scrub of dirty spots, a rinse and air drying. Use a machine only when the tag says so, and never soak a leather leash. If you want to read more about leash choices, see best dog leash for bike riding or best inside a retractable dog leash.
