How To Wash Hiking Boots In A Washing Machine | Don’t Do It

You should not wash hiking boots in a washing machine; the agitation, heat, and detergent can damage the materials, adhesives.

You just finished a weekend on muddy trails. Your hiking boots are caked with dirt, smell a little off, and look like they need a full reset. It’s tempting to toss them in the washing machine with a splash of detergent and let modern appliances do the heavy lifting.

That impulse makes sense, but outdoor gear experts are unanimous: machine washing can wreck your boots. This article explains why the washing machine is off-limits, walks through a proper hand-cleaning routine, and covers drying and waterproofing so your boots last longer without damage.

Why Machine Washing Ruins Hiking Boots

Hiking boots are complex. They combine leather, synthetic fabrics, foam midsoles, rubber outsoles, and often a waterproof membrane like Gore‑Tex. Each layer is bonded with adhesives that don’t hold up well to the spin cycle.

Agitation in a washing machine can separate the sole from the upper and compress the midsole foam, reducing cushioning. Hot water softens and weakens glues. Detergent can strip waterproof coatings and leave residue inside the boot that irritates your feet on the next hike.

REI’s care guide calls this out clearly: never put boots in a washing machine. Columbia’s official instructions agree, noting that the combination of detergent, heat, and spinning can break down materials. The consensus across manufacturers is that hand washing is the only safe method.

Why People Think Machine Washing Is Okay

The idea comes from convenience. Washing machines handle muddy jeans and fleeces without issue, so why not boots? The difference is that boots aren’t flexible textiles — they’re structured gear with glued and stitched parts that aren’t designed for tumbling.

• The spin cycle applies force unevenly. A boot is heavy and asymmetrical. As it spins, it bangs against the drum and its own weight can tear the fabric or loosen the sole.
• Heat is a hidden enemy. Even a warm wash can reach temperatures that soften adhesives. Many boot warranties explicitly exclude damage from machine washing or drying.
• Detergent residue stays inside. Boots have thick padding and nooks where soap can collect. That residue can cause skin irritation and attract dirt faster next time.
• Waterproof membranes can delaminate. The combination of agitation and chemicals can separate the thin membrane layer from the outer fabric, leaving you with boots that leak.
• Foam midsoles lose shape. Repeated washing compresses the EVA or polyurethane foam that provides cushioning, making the boot feel flat sooner than it should.

The good news is that proper hand washing takes about 15 minutes of active time. Most of the cleaning process is just soaking and rinsing, not scrubbing.

Step‑By‑Step Hand Washing Guide

Cleaning hiking boots by hand is straightforward. You’ll need a bucket or sink, lukewarm water, a soft brush or cloth, and a boot‑specific cleaner (dish soap is too harsh). Gather these before you start.

First, remove the laces and insoles. Laces can go right in the washing machine or dishwasher — never put boots in washing has that tip — but the boots themselves stay out. Insoles can be hand‑washed separately with mild soap and air‑dried.

Tap the boots together outside to knock off loose mud and stones. Then brush off dried dirt with a soft brush, paying attention to seams and eyelets where grime collects. For stubborn dirt, dip the brush in lukewarm water — never hot water, which can damage adhesives and materials.

Step	Action	Tip
1. Remove laces & insoles	Take out laces and footbeds	Wash laces separately in a pillowcase or washing machine
2. Knock off loose debris	Tap boots together outside	Use a stick to dislodge packed mud in treads
3. Brush dry dirt	Use soft brush on seams and eyelets	An old toothbrush works well for crevices
4. Wash with cleaner	Dip brush in lukewarm water + boot cleaner	Be gentle; don’t force or scrub hard
5. Rinse thoroughly	Rinse with clean lukewarm water	Make sure no soap residue remains inside
6. Dry and waterproof	Air dry, then apply treatment	Waterproof while boots are still damp

After rinsing, squeeze out excess water with a towel — don’t wring the boot. Remove the boots from the water and let them sit for a moment. If you plan to re‑waterproof, do it while the leather or fabric is still damp so the treatment absorbs evenly.

How To Dry And Waterproof Your Boots

Drying boots incorrectly can undo all your cleaning work. Heat is the biggest threat: never put boots near a radiator, in a dryer, or in direct sunlight. High temperatures cause leather to crack, foam to shrink, and glue to fail.

1. Stuff the boots with newspaper or paper towels. Change the paper every few hours to pull moisture from the inside. This speeds drying without heat and helps the boots hold their shape.
2. Let them air dry at room temperature. Place them in a well‑ventilated area, ideally upside down on a drying rack so air can circulate inside the footbed. Expect 24 to 48 hours for full drying.
3. Apply a waterproofing treatment once the boots are almost dry but still slightly damp. Use a spray or wax designed for your boot material (leather, nubuck, or synthetic). Follow the product instructions — most require you to let the treatment soak in for 10‑15 minutes before buffing.
4. Re‑lace and re‑insert the insoles only after the boots are completely dry. Putting in damp insoles can trap moisture and cause odors or mold.

If you hike regularly, consider buying a boot dryer that uses cool air circulation. These devices gently dry the inside without heat and can extend the life of your boots significantly.

Common Boot Cleaning Mistakes To Avoid

Even with good intentions, a few errors can shorten your boot’s lifespan. The most common is reaching for harsh soaps like dish detergent. According to to wash hiking boots, the chemicals in household cleaners can damage leather and strip waterproof coatings. Stick to products labeled for boots or technical footwear.

Another mistake is skipping the rinse step. Soap residue left inside the boot can attract dirt and cause skin irritation on long hikes. Take the extra 30 seconds to flush out the interior with clean water.

Mistake	Why It Hurts	Better Alternative
Using hot water	Weakens adhesives and can crack leather	Lukewarm water only
Scrubbing aggressively	Scratches leather and damages fabric	Gentle brushing with soft bristles
Putting boots in a dryer	Shrinks materials and melts glue	Air dry at room temperature with newspaper

Finally, don’t skip regular maintenance. Brushing off dirt after every hike takes two minutes and reduces the need for deep cleaning. Spot‑clean stains early before they set. A little prevention keeps boots performing well for years.

The Bottom Line

Machine washing hiking boots is a shortcut that backfires. The consensus from REI, Columbia, and other outdoor gear authorities is clear: hand wash only. Remove laces, tap off mud, brush gently, use lukewarm water and a boot‑specific cleaner, rinse well, and air dry away from heat. Waterproof while damp, and your boots will handle many more miles.

If you’re unsure about the best method for your specific boot material, ask the staff at your local gear retailer — they can recommend a cleaner and waterproofing product that matches your boot’s construction and the terrain you hike.
