TL;DR
Road salt is the reason dog boots need cleaning promptly rather than eventually. Knock the dry grit off, rinse the salt out with plain water within a day, wash with unscented soap, and dry the boots completely inside and out. A damp boot rubs, and rubbing is what causes sores between the toes.
Why boots need more care than the rest of the kit
Boots take the worst of every walk. They collect mud, grit, road salt, ice melt chemicals, and whatever is on the ground, and then they wrap that around a paw.
Grit is abrasive and works into the seams and the tread. Salt is corrosive to hook-and-loop fasteners and hard on skin. And a boot that dries with grit inside becomes sandpaper on the next walk.
Because boots come in pairs of four, they also get skipped. Cleaning one coat is easy; cleaning eight boots feels like a job. The trick is a two-minute rinse after each walk and a full wash occasionally, rather than the reverse.
Sort your boots by material
Fabric and mesh boots. Soft-sided with a rubber or synthetic sole. Machine washable in most cases, and quick to dry.
Rubber and silicone boots. Thin, disposable-style or reusable rubber shells. Rinse, wash, and dry inside out. Never dry these with heat, which makes rubber brittle.
Neoprene boots. Warm, water-resistant, and slow to dry. Hand wash and give them a long dry, because neoprene holds water like foam.
Leather-soled boots. Wipe rather than soak, and condition the leather afterward.
Check the label. Where the manufacturer's instructions differ from general advice, follow the label.
How do you wash dog boots?
Knock off the dry grit, then rinse each boot inside and out under warm running water to flush the salt. Wash with a small amount of unscented soap and a soft brush, working the tread and the seams. Rinse thoroughly, then air dry them completely inside and out.
The step-by-step routine
1. Knock the boots together outside. Dry grit falls out. Wet grit smears.
2. Turn each boot inside out if the design allows. Debris collects in the toe, which is exactly the part that never gets cleaned otherwise.
3. Rinse in plain warm water first. This is the salt step, and it matters more than the soap step. Do it the same day.
4. Wash with unscented soap. A drop of dish soap or an unscented laundry soap in warm water. Skip anything strongly fragranced, since a dog's nose spends the walk near the ground and the boots.
5. Brush the tread and the seams. An old toothbrush gets grit out of a lug pattern and out of the stitched seam where the sole meets the upper.
6. Clean the fastener strips. Pick fur and grit out of the hooked side with a comb or a stiff brush. A fastener full of fur is the reason boots come off mid-walk.
7. Rinse until no suds appear. Residue inside a boot irritates skin.
8. Dry completely, inside and out. Stand them open, upside down, somewhere with moving air. Neoprene can take a full day.
Machine washing works for fabric boots inside a mesh laundry bag on a cool gentle cycle with unscented detergent and no fabric softener. Softener leaves a slick film that ruins grip and clogs fasteners.
Never use a machine dryer. Heat shrinks fabric, hardens rubber, warps soles, and kills elastic.
Road salt and ice melt deserve their own step
Ice melt products are salts, and salts do three things: corrode hardware, dry out fabric, and irritate paw skin. Some formulations are harsher than others.
Rinse boots in plain water after any walk on treated pavement, and do it that day rather than at the weekend. Salt left to dry crystallizes into the fibers and the fastener strips.
Rinse your dog's paws too, and dry between the toes. If your dog has been walking without boots on treated ground, or licks the paws afterward, that is a conversation for your veterinarian, especially with a small dog. Ice melt ingestion is a real concern and a vet is the right source of advice on it, not a cleaning guide.
Salt corrodes fasteners and metal on coats as well, which is why the same rinse rule appears in how to wash a dog coat.

Getting the smell out
Boots get sour for the same reason shoes do. Warm, damp, enclosed, and organic.
Wash them with an enzyme-based laundry product, soaking for an hour first, then rinse hard. Enzymes break down the oils and proteins that plain soap only loosens.
Baking soda sprinkled inside a dry boot overnight and shaken out helps between washes.
Do not use chlorine bleach. It weakens fabric and stitching, and it must never be mixed with ammonia, which is present in urine, or with vinegar or any other acid. Those combinations release chloramine and chlorine gas.
If a boot smells strongly no matter what, check the paw. Persistent odor, redness, licking, or limping is a veterinary matter, not a laundry problem.
Check the fit and the wear while they dry
Boots are consumable. The sole wears through, the seams open, and the fastener strips stop gripping.
Look at the tread for thin spots, the seam where the sole meets the upper for separation, and the inside for rough patches or hardened material. Run a finger inside the toe, since that is where a stiff ridge forms and where a sore starts.
Check the fastener. If it will not hold when you pull, replace the boots rather than adding tape.
Then check the fit on your dog. A boot should be snug enough not to twist but not tight, and the fastener should sit above the dewclaw without pinching. Boots that go on wet or with grit inside cause rubbing between the toes, which is the most common boot injury and entirely preventable.
How often should you clean dog boots?
Rinse after every walk on treated pavement, sand, or salt, and after mud. Do a full wash every week or two in heavy winter use, and always before storing them at the end of the season.
Store them dry and loose, not sealed in a bag while damp. Two sets in rotation solves the drying problem, in the same way two harnesses do in how to clean a dog harness.
At the end of winter, wash and dry the whole set, check for wear, and put the survivors away clean. The rest of the pet kit follows the same rinse-hard and dry-fully logic, collected in our guide to cleaning pet bowls, bedding, toys and gear.
FAQ
Can you put dog boots in the washing machine?
Fabric and mesh boots usually can, inside a mesh laundry bag on a cool gentle cycle with unscented detergent and no fabric softener. Knock the grit off first. Never machine dry them, because heat shrinks fabric, hardens rubber soles, and destroys the elastic and fasteners.
How do you get road salt out of dog boots?
Rinse each boot inside and out in plain warm water the same day you walk on treated pavement, before the salt dries into the fibers. Then wash with unscented soap and rinse again. Salt left to crystallize corrodes fasteners, stiffens fabric, and irritates paw skin.
How do you get the smell out of dog booties?
Soak them for an hour in warm water with an enzyme-based laundry product, wash with unscented soap, and rinse until no suds appear. Dry them completely inside and out. Persistent smell despite proper washing can mean a paw problem, which is a question for your veterinarian.
How do you stop dog boots falling off?
Most of the time the fastener strips have filled with fur and stopped gripping. Comb the fur out of the hooked side with a stiff brush after each wash. Check the fit as well, since a boot that is loose or twisted will work its way off within a few minutes.
How often should you wash dog boots?
Rinse after every walk on salt, sand, or mud, and do a full wash every week or two during heavy winter use. Always wash and dry the whole set before storing it at the end of the season, and store the boots loose and dry rather than sealed in a bag.
Can you use a dryer or a radiator to dry dog boots?
No. Heat hardens rubber soles, shrinks fabric uppers, warps the shape, and ruins elastic. Stand the boots open and upside down somewhere with moving air instead. Neoprene boots need a full day, and putting a damp boot back on a paw causes rubbing.
Gear is the quick part. The entryway, floors, and beds all that mud ends up on are the bigger job, and every home is different, so the real number depends on size, condition, and what you want covered. Get a quote or read more about house cleaning services.
