Dirt, salt and concrete dust pull moisture out of leather and grind into the stitching. Leave them there and boots crack, stiffen and leak far sooner than they should. A simple cleaning routine takes about 15 minutes and can add months to a pair’s life.
Key points
- Brush off dirt after every dirty shift.
- Clean fully every few weeks, or right away after salt, concrete or chemicals.
- Always condition leather after washing it.
- Never use a washing machine or direct heat.
What you need
- A stiff brush (horsehair or nylon) and an old toothbrush
- A bucket of lukewarm water and a cloth or sponge
- Saddle soap or a leather cleaner
- Leather conditioner suited to your boot’s leather
- Newspaper or a boot tree
Step 1: Prep the boots
Remove the laces and, if possible, the insoles. This lets you reach the tongue and lets the inside dry properly afterwards.

Step 2: Dry-brush the dirt off
Knock the soles together outside to shake off loose mud. Brush the uppers firmly, paying attention to the welt seam where the upper meets the sole. Use the toothbrush to clear the stitching and the tread.
Step 3: Wash with saddle soap or cleaner
Dampen the cloth, work up a light lather on the soap, and clean the leather in small circles. Don’t soak the boot. Wipe off the lather with a clean damp cloth.
Step 4: Deal with problem stains
Road salt
White salt lines draw moisture from leather and can crack it. Wipe them with a mix of roughly one part white vinegar to two parts water, then clean again with plain water.
Concrete and mortar
Wet concrete is alkaline and dries leather quickly. Rinse it off as soon as you can. Once it’s dry, brush off as much as possible, then use the vinegar-water mix to neutralise the residue before conditioning.
Oil and grease
Blot fresh oil straight away. Sprinkle cornstarch or talc on the stain, leave it overnight to draw out the oil, then brush it off. Oil-tanned leathers hide these marks better than others.
Step 5: Dry slowly
Stuff the boots with newspaper and leave them at room temperature, away from heaters, fires and direct sun. Change the newspaper after a few hours. See how to dry wet boots for more detail.
Step 6: Condition
When the boots are dry but not bone-dry, apply a thin coat of conditioner with a cloth or your fingers, working it into seams and creases. Let it soak in for about 20 minutes, then buff off the excess. Leather that’s still slightly supple takes conditioner best.

Step 7: Waterproof if needed
If you work in the wet, finish with a wax or spray treatment. Our waterproofing guide explains which to use.
How often to clean
| Conditions | Brush | Full clean and condition |
|---|---|---|
| Dry, indoor | Weekly | Every 1 to 2 months |
| Mud and outdoor sites | After dirty shifts | Every 2 to 4 weeks |
| Salt, concrete, chemicals | Same day | Weekly or after exposure |
Regular cleaning also helps you spot wear early. Look out for the signs in when to replace work boots.
Frequently asked questions
How often should I clean my work boots?
Brush off dirt at the end of any dirty shift, and give them a full clean and condition every two to four weeks with daily wear, or sooner after exposure to salt, concrete or chemicals.
Can I put work boots in the washing machine?
No. Machine washing can crack leather, weaken adhesives and damage membranes and safety components. Clean by hand.
Can I use dish soap on leather boots?
A small amount of mild soap in water is fine for occasional cleaning, but it strips oils, so always condition afterwards. A dedicated leather cleaner or saddle soap is gentler.
