How To Wash Leather Hiking Boots | The Right Way

Clean leather hiking boots by hand using a soft brush, mild soap, and water — never a washing.

You just finished a muddy trail, and your leather hiking boots look like they’ve been through a bog. It’s tempting to toss them into the washing machine with the rest of your gear. That’s the fastest way to wreck the leather and ruin the waterproofing.

The real method is simpler and takes about as long. With a soft brush, a bucket of warm water, and a gentle cleaner, you can get them looking like new without damaging the material. This article walks through each step.

Prep Work Before You Wash

Start by pulling out the laces and insoles. Laces can go in the washing machine on a gentle cycle or in a mesh bag. Insoles can soak in soapy water, then air-dry separately. This lets you get into every seam.

A soft brush works best for knocking off loose dirt and dust. Run it over the entire boot, paying close attention to creases and the welt where mud hides. For stubborn grime in seams, an old toothbrush handles crevices well.

If the boots are very wet from rain or puddles, blot them first with a dry cloth. Washing waterlogged leather can push dirt deeper into the pores.

Why Hand Washing Matters More Than You Think

People often assume a machine cycle is thorough enough. The problem is that the tumbling action stresses leather fibers and can delaminate waterproof membranes. Once they separate, your boots leak.

Here’s what machine washing does to leather boots:

• Damages the leather surface: Detergents strip natural oils, leaving the leather dry and prone to cracking.
• Ruins waterproof linings: Aggressive agitation can separate the inner membrane from the outer leather.
• Bends the boot shape: The machine flexes the boots in ways they aren’t designed for, weakening the construction over time.
• Rusts eyelets and hardware: Prolonged water exposure can oxidize metal parts, making lacing difficult.
• Leaves residue inside: Soap can get trapped in padding, leading to odors or mold.

A gentle hand wash avoids all these issues. You control the pressure and can rinse thoroughly. It takes twenty minutes and keeps your boots going for years.

The Step-By-Step Wash Process

Once the laces and insoles are out and the loose dirt is brushed off, run the boots under hot (not scalding) water to loosen any remaining grit. Then apply a dedicated boot cleaner or a few drops of mild dish soap. REI’s guide on how to remove laces and insoles also covers the basics of scrubbing technique.

Use a soft brush or a cloth to work the cleaner in circular motions. Focus on stained areas and the welt. For deep crevices, an old toothbrush helps. Rinse with cold water until no suds remain — leftover soap can attract dirt.

If you spot mold, a solution of 80 percent water and 20 percent white vinegar can kill it. Apply with a cloth, let sit a few minutes, then rinse. After rinsing, blot excess water with a towel.

Tool	Purpose	Best For
Soft brush	Removing loose dirt	Entire boot surface
Old toothbrush	Scrub seams and crevices	Welt and tread
Boot cleaner / saddle soap	Deep cleaning without stripping oils	Full leather panels
Mild dish soap	Gentle alternative to boot cleaner	Light soil on smooth leather
White vinegar (20% solution)	Mold removal	Infected spots only

Whichever cleaner you pick, always rinse thoroughly. Residual cleaning agent can cause the leather to dry out faster and may affect the waterproofing.

Drying and Conditioning Your Boots

How you dry leather boots is as important as how you wash them. High heat — from radiators, hair dryers, or direct sunlight — can make the leather stiff and brittle. Slow, natural drying preserves flexibility.

1. Remove excess water: Pat the boots with a clean, dry towel until they are just damp, not soaking.
2. Air dry away from heat: Set them in a well-ventilated area at room temperature. Stuff them with newspaper to help them hold their shape and absorb moisture from inside.
3. Condition the leather: Once dry (usually 24 hours), apply a leather conditioner. Work it into the leather with your fingers or a cloth. This replaces oils lost during washing and prevents cracking.
4. Apply waterproofing wax: After conditioning, use a wax-based product to restore water resistance. Spread a thin layer and let it absorb overnight.

Restoring Waterproofing and Ongoing Maintenance

Cleaning strips away some of the original factory waterproofing, so reapplying a wax-based treatment is essential. Columbia’s guide recommends mild soap for cleaning and then following up with a waterproofing wax for full protection. The wax also adds a layer of scuff resistance.

WD-40 can give temporary waterproofing, but it darkens the leather and doesn’t condition — it’s a stopgap, not a routine treatment. Stick with products made for leather boots.

For everyday care, a quick brush after each hike removes abrasive dirt before it gets ground into the grain. Avoid bar soap or laundry detergent; their additives can harm leather and membranes.

Task	Frequency
Brush off dirt after each hike	After every use
Deep clean and condition	Every 2–3 months or when visibly dirty
Reapply waterproofing wax	Every 3–6 months or when water no longer beads

The Bottom Line

Washing leather hiking boots by hand is straightforward: remove the laces and insoles, brush off dirt, clean with a mild soap and soft brush, rinse thoroughly, air dry away from heat, condition, and reapply waterproofing. This method keeps the leather supple and the membranes intact.

If you’re unsure about a specific cleaner or wax for your boot brand, a local outdoor retailer’s staff can point you to compatible products based on the leather type and terrain you hike.
