How to Clean Hiking Boots: Complete Guide for All Boot Types

To clean hiking boots, remove loose mud with a stiff brush while still damp, rinse with cool water, scrub the upper and sole with a boot-specific cleaner, then dry naturally away from direct heat. Full cleaning takes 10 to 20 minutes. The method varies by material: leather, suede, synthetic, and Gore-Tex each need a different approach.

Hiking boots take a beating on every outing, and a proper cleaning routine is the single most effective way to protect that investment. Dirt, organic acids from mud, and salt from sweat break down stitching, degrade adhesives, and block the waterproof membrane that keeps your feet dry. This guide covers everything you need: the general method, material-specific protocols, drying, re-waterproofing, and how often to do it all.

How to Clean Hiking Boots

Why Cleaning Hiking Boots Properly Matters

It is easy to treat a muddy boot as a cosmetic problem. The real damage, however, is structural. Mud contains organic acids and fine particles that work their way into the stitching and welt seam over time, weakening the bond between upper and sole. On leather boots, dried mud draws out the natural oils that keep the material supple, accelerating cracking. On boots with a Gore-Tex or similar membrane, a build-up of grime blocks the microscopic pores that allow breathability, making the boot feel damp from the inside even when the exterior is dry.

Waterproofing is the other casualty of neglect. The DWR (Durable Water Repellency) coating on the outer fabric is degraded by body oils, mud residue, and detergent residue from improper washing. Once DWR fails, the outer fabric becomes wet and heavy even if the membrane is still functioning. Regular cleaning restores the surface and allows the waterproofing treatment to bond properly when re-applied.

The practical outcome of a consistent cleaning routine is straightforward: boots last significantly longer, stay waterproof for more seasons, and remain comfortable across varying terrain. Replacing a pair of quality hiking boots costs between EUR 100 and EUR 350 across the EU market. Cleaning products cost a fraction of that.

Once your boots are clean and in good condition, a proper break-in process ensures they perform at their best. See our guide: How to Break In Hiking Boots: A 21-Day Plan for Walkers.

What You Need Before You Start

Having the right tools assembled before you begin makes the process faster and reduces the risk of using the wrong product on the wrong material. The table below covers everything needed for a full clean, including which items are material-specific.

The most important rule before buying anything: check your boot material. Using a standard leather conditioner on suede or nubuck will permanently darken and damage the nap. Using a harsh detergent on Gore-Tex lined boots strips the DWR coating. When in doubt, use a boot-specific wash rated safe for all materials.

You can find boot-specific cleaners, conditioners, and waterproofing sprays in the Buzzastore Shoe Care collection.

What You Need to Clean Hiking Boots

A stiff-bristled brush, a softer cloth, lukewarm water, and mild soap handle most cleans. For regular UK walkers, add a waterproofing spray such as Nikwax or Grangers and a leather conditioner for leather boots. If your current pair needs replacing, quality European options such as the M77 Norwegian Combat Boots at Buzzastore offer full-grain leather construction built to military standards.

Step-by-Step: How to Clean Hiking Boots (General Method)

This six-step process applies to all boot types. Material-specific variations are covered in the sections below. Always complete the general clean first before applying any conditioning or waterproofing treatment.

Step 1: Remove Laces and Insoles

Take out the laces and pull the insoles free before doing anything else. Laces trap grit at every crossing point, and insoles hold moisture and odour that needs to be dealt with separately. Wash laces by hand in warm water with a small amount of boot wash. Set insoles aside to air separately.

Step 2: Knock Off Loose Mud While Still Damp

Dried mud is significantly harder to remove than damp mud and requires more aggressive scrubbing that can scuff the upper. If you have just returned from a walk, tap the soles together over a bin or outdoors to dislodge the bulk of the mud before it sets. If the mud has already dried, use a stiff brush to break it up before rinsing.

Step 3: Brush the Uppers and Outsole

Use a stiff-bristle brush on the outsole to clear the lug grooves, which trap mud and stones that accelerate wear. Switch to a softer brush or cloth for the upper to avoid scuffing the material. Work around the welt seam carefully, as this is where grit accumulates and causes the most structural damage over time.

Step 4: Apply Boot Cleaner and Scrub

Apply a small amount of boot-specific cleaner to a damp cloth or soft brush and work it into the upper using circular motions. Do not saturate the boot; you need enough product to lift the dirt, not to soak the material. Pay extra attention to the collar, tongue, and any reinforced panels where dirt collects.

Keeping feet dry between walks matters too: the M77 Inner Socks reduce interior moisture build-up and extend the freshness of a clean pair.

Step 5: Rinse with Cool Water

Rinse the boot thoroughly with cool running water to remove all traces of the cleaner. Residual cleaner left on the surface can attract more dirt and, on Gore-Tex lined boots, interfere with breathability. Do not use hot water; it softens adhesives and can cause the sole to begin separating from the upper.

Step 6: Dry Naturally

Pat the boots dry with a clean cloth to remove surface water, then allow them to dry naturally at room temperature. Loosen the laces fully, insert a boot tree or crumpled newspaper to maintain the shape, and leave them in a well-ventilated spot. Full drying typically takes 12 to 24 hours depending on how wet the boots got. See the drying section below for a full method comparison.

How to Clean Muddy Hiking Boots

UK mud deserves its own section. Timing matters more than most guides acknowledge, and the approach differs significantly depending on whether the mud is fresh or dry.

Act Fast: What to Do in the First 30 Minutes

If you are near a stream or outdoor tap, rinse the boots before heading home. Removing fresh mud while wet takes seconds; scrubbing dried Peak District clay from textured leather can take far longer. Once home, set the boots on newspaper immediately. Even after an exhausting walk, this simple habit makes the full clean much quicker the following day.

Dealing with Dried Mud and Clearing Outsole Tread

Start completely dry for dried mud: use a stiff brush to break and knock off the crust before adding any water. Wetting dried mud first turns it back into a paste that smears rather than lifts. Once the dried crust is cleared, follow the standard steps above. For the outsole lugs, soak just the base of the boot in shallow water for a few minutes before brushing to dislodge packed grit. If your outsole tread is wearing smooth regardless of cleaning, it may be time for a replacement. The Widget Black Shoes at Buzzastore offer NATO-standard genuine leather construction for everyday durability in UK conditions.

How to Clean Full-Grain Leather Hiking Boots

Full-grain leather is the most durable hiking boot upper material and, when properly maintained, the longest lasting. It is also the most demanding to clean correctly. Avoid dish soap, household detergents, and saddle soap unless specifically formulated for hiking boots, as these strip the natural oils from the leather.

Apply Nikwax Leather Wash or Grangers Boot Care to the damp upper using a soft cloth, working the product into the leather in circular motions. Rinse thoroughly with cool water. Once the boot is clean and still slightly damp, apply a thin coat of leather conditioner to the full upper, including the tongue and collar. The conditioner penetrates while the pores are open from the cleaning process and restores the suppleness lost from washing. Buff with a clean dry cloth.

Condition leather boots after every two to three cleans in wet, muddy conditions, and at the start and end of each walking season. Over-conditioning is also possible: a boot that receives too much conditioner becomes overly soft and loses its structural support.

How to Clean Suede and Nubuck Hiking Boots

Suede and nubuck require a more cautious approach than smooth leather. Both materials have a raised, textured nap that traps dirt and is easily damaged by excess water or the wrong cleaning product. Never use a standard leather conditioner on suede or nubuck; it will flatten the nap permanently and cause uneven dark patches.

Allow any mud to dry completely before attempting to remove it. Trying to clean wet mud from suede or nubuck smears the dirt deeper into the fibres. Once dry, use a suede brush to lift the mud away using short, firm strokes in one direction. For stubborn marks, apply a small amount of suede-specific cleaner to the brush rather than directly to the boot.

After cleaning, use the suede brush again to restore the nap by brushing lightly in a consistent direction. Finish with a suede-safe waterproofing spray, not a wax-based product, which will again damage the texture. Allow to dry fully before wearing.

How to Clean Synthetic and Mesh Hiking Boots

Synthetic uppers and mesh boots are the easiest to clean and the quickest to dry, but they are the most prone to odour retention. The open weave of mesh traps bacteria from sweat and soil that can make the inside of the boot unpleasant even after a surface clean.

Synthetic uppers tolerate a slightly more robust cleaning approach than leather or suede. A mild boot wash applied with a soft brush works well. Rinse thoroughly with cool water and press a dry cloth against the mesh panels to draw out moisture before air-drying. Do not wring or twist the boot.

For the insoles and boot interior, sprinkle a small amount of bicarbonate of soda inside the dry boot and leave overnight before tapping it out. This neutralises odour-causing bacteria effectively and requires no moisture. For persistent odours, a boot-specific deodoriser spray is the next step.

How to Clean Gore-Tex Lined Hiking Boots

Gore-Tex and similar waterproof-breathable membranes are sensitive to the wrong cleaning products. Fabric softener, standard detergent, and household soap all leave a residue on the outer face fabric that physically blocks the membrane pores and permanently reduces breathability. Always use a non-detergent boot wash rated safe for waterproof membranes.

The cleaning process on the exterior is the same as the general method: brush, wash with a boot-specific product, rinse with cool water. Pay particular attention to a complete rinse, as any remaining product on the face fabric will interfere with the DWR coating.

After cleaning and drying, check whether the DWR is still performing by sprinkling a few drops of water on the upper. If the water beads and rolls off, the DWR is active. If the water soaks into the face fabric and darkens it, the DWR needs reactivating. For recently cleaned boots, tumble drying on a very low heat for 20 minutes can reactivate an existing DWR treatment without applying a new product. If that does not work, apply a DWR spray formulated for Gore-Tex, such as Nikwax Fabric and Leather Proof or Grangers Performance Repel.

The table below summarises the key cleaning rules for each material at a glance.

Full-grain leather needs conditioning after every clean; suede and nubuck need a suede brush and suede-safe products only. Synthetic mesh is the most forgiving to wash but needs the most attention to interior odour. Gore-Tex lined boots should never be washed with detergent or fabric softener.

How to Dry Hiking Boots Properly

Drying is the step most walkers get wrong. A boot that has been washed correctly but dried on a radiator will crack at the toe box and separate at the welt seam within a season. The golden rule is simple: cool air, slow drying, shape maintained.

Room temperature drying with a boot tree or newspaper inside is the safest and most effective method for all materials. An electric boot dryer on its lowest setting is an acceptable shortcut, particularly for regular walkers in wet conditions, but it should not be used on boots with visible adhesive stress or beginning sole separation.

When and How to Re-Waterproof After Cleaning

Cleaning removes the dirt but also strips or weakens the DWR waterproofing treatment on the outer fabric. Re-waterproofing after a clean is not optional for boots used in wet European conditions; it is part of the maintenance cycle.

The beading test is the simplest way to check DWR status: flick a few drops of water onto the upper. Water that beads and rolls off indicates active DWR. Water that soaks into the fabric surface and darkens it means the treatment needs refreshing.

Spray-on waterproofing is best for synthetic and mesh uppers; wax-based products are more durable on full-grain leather. Apply waterproofing to a clean, slightly damp boot for the best absorption, following the product instructions. Allow to dry fully before the next outing.

Nikwax and Grangers are both widely available across EU outdoor retailers and online, with similar price points. Nikwax holds a certified Gore-Tex Safe status for most of its hiking boot range, which is worth noting if your boots have a Gore-Tex lining. Grangers performs well on odour control for synthetic mesh boots. Either brand will maintain your boots effectively when used as directed.

How Often Should You Clean Hiking Boots?

There is no single correct frequency. The right cleaning schedule depends on how often you walk, the terrain and conditions you walk in, and the material your boots are made from. The table below gives practical guidelines across four usage levels.

The key principle across all usage levels is this: clean before the dirt dries and hardens, and re-waterproof as soon as the beading test fails. Boots that are cleaned regularly after shorter walks are significantly easier to maintain than boots that are left to accumulate several outings of caked mud before anyone deals with them.

Frequently Asked Questions

Below are the questions most commonly asked by walkers when learning how to clean hiking boots, each answered directly.

Can you put hiking boots in the washing machine?

No. Machine washing damages the sole adhesive, distorts the midsole foam, and can destroy a Gore-Tex lining. Even boots that survive a single machine wash are structurally weakened. Always hand-wash with a boot-specific cleaner.

Can I use washing up liquid to clean hiking boots?

It is not recommended. Washing up liquid is a detergent that strips the DWR coating from the outer fabric and dries out leather. It also leaves a residue that attracts more dirt. A boot-specific wash costs only slightly more and does the job without the side effects.

How long do hiking boots take to dry?

At room temperature with laces loosened and newspaper inside, most boots are fully dry in 12 to 24 hours. Heavily saturated leather boots may take up to 36 hours. Never speed up the process with direct heat; the structural damage is not worth the time saved.

Can you use a hairdryer on hiking boots?

No. Concentrated heat from a hairdryer cracks leather, weakens adhesives, and degrades synthetic materials. If you need to speed up drying, use an electric boot dryer on its lowest setting from a distance of at least 30 centimetres.

How do I get rid of the smell inside hiking boots?

Remove the insoles and air them separately after every walk. For existing odour, sprinkle bicarbonate of soda inside the dry boot and leave overnight before tapping it out. A boot-specific deodoriser spray applied to the lining is the next step for persistent cases. Washing the boot interior with a damp cloth and boot-specific cleaner addresses bacteria build-up at the source.

Should I clean my boots after every walk?

Not necessarily. A quick brush-off and air after every walk is good practice. A full wash is needed after walks in wet or muddy conditions, after off-trail or boggy terrain, and before long-term storage. See the frequency table above for guidance based on your usage level.

Does cleaning affect the waterproofing of hiking boots?

Cleaning with the correct products does not damage waterproofing and actually prepares the surface for re-treatment. Cleaning with detergent, fabric softener, or washing-up liquid does damage DWR. Always use a non-detergent boot wash and follow with a waterproofing spray after the boots are dry.
