How to get the smoke smell out of a leather jacket (plus musty, thrift-store and mildew smells)

Short answer: air it, absorb it, then treat the lining, not the leather. Most of a smoke smell lives in the lining, the seams and the pores of the leather surface. A week of airing in shade, a few days sealed in a bag with an odour absorber such as activated charcoal or baking soda, and a light, tested mist on the lining remove most cigarette, bonfire and thrift-store smells. Don’t wash, steam, perfume or “ozone” the leather. If the smell is still strong after two rounds, a specialist leather cleaner is the next step, and some heavy, years-old smoke smells never fully leave.

That matters right now. October and November are when people pull a jacket out of storage, pick one up second-hand, or come home from a bonfire or a smoky bar. Here is how to fix each kind of smell without damaging the jacket.

First, work out what kind of smell it is

Different smells come from different places in the jacket, and the fix depends on where it sits.

Smell	Usually comes from	Where it sits	Best first fix	Realistic outcome
Fresh smoke (one night at a bar, a bonfire, a barbecue)	Smoke particles on the surface	Leather surface, lining, collar	Air it for 2–3 days	Usually gone completely
Old cigarette smoke (a smoker’s jacket, years of wear)	Tar and nicotine residue built up over time	Deep in the lining, seams, padding and leather pores	Air, absorb, treat the lining; repeat	Big improvement; a faint smell may come back on damp days
Musty / closet smell	Stale air and damp in storage	Lining and inside pockets	Air, then absorb in a sealed bag	Usually gone
Thrift-store / vintage smell	A mix of old perfume, smoke, damp and store “fresheners”	Mostly the lining	Air, absorb, treat the lining	Usually gone or close to it
Mildew / mould (sour, earthy, often with white or green spots)	Mould growth from damp storage	Surface, seams, lining	Treat the mould first (see below), then deodorise	Smell goes once the mould is gone; recurring mould needs a cleaner
“Leather” or chemical smell on a new jacket	Tanning and finishing	Leather itself	Air it; it fades with wear	Normal; fades over weeks
Body odour / sweat	Sweat in the lining, collar and underarms	Lining	Treat the lining	Usually gone

A useful test: sniff the inside and the outside separately. If the lining smells far worse than the leather (it usually does), most of your effort goes into the lining. If the outside leather smells strongly too, expect to repeat the airing and absorbing steps.

Why smoke clings so stubbornly

Tobacco smoke leaves a sticky residue, often called thirdhand smoke, that settles on surfaces and soaks into fabrics. Researchers at UC Riverside and UC San Francisco tested how that residue behaves in different fabrics (Pozuelos and colleagues, International Journal of Environmental Research and Public Health, 2021). Two findings explain what jacket owners notice:

• Fabric type matters. In their tests, far more nicotine could be extracted from cotton terry cloth than from polyester, which held on to it tightly when dry. Linings made of different fibres will release smoke differently.
• Humidity brings it back. In high humidity, much more of the nicotine came out of both cotton and polyester. That is why a jacket you thought was fixed can smell of smoke again on a rainy day: moisture releases residue that dry air couldn’t.

A San Diego State University team that studies thirdhand smoke has also said that residue from light or recent smoking tends to sit on the surface and can be wiped or washed off, while heavy, long-term smoking embeds it much deeper. For a jacket, that means a one-night bonfire smell is easy; a jacket worn by a heavy smoker for a decade is a project.

The 7-day plan for smoke and musty smells

This works for smooth leather, suede and shearling. Do the steps in order and stop when the smell is gone.

Before you start: empty every pocket, open all zips and vents, and remove any detachable hood, collar or zip-out liner (those can usually be cleaned on their own, following their care label).

Days 1–3: air it in shade

1. Hang the jacket on a wide, shaped hanger (not wire) so the shoulders keep their shape.
2. Put it somewhere with moving air and out of direct sun: a covered balcony, a porch, a spare room with the window open, or near (not in front of) a fan.
3. Leave it for 2–3 days. Turn it inside out for one of those days so the lining gets the air.

Keep it at room temperature, about 18–24 °C (65–75 °F), and dry. Avoid long spells in strong sun: UV and heat fade dye and dry leather out. Bring it in if it rains or the air turns very damp, for the humidity reason above.

Fresh smoke smells are usually gone at this point. If not, go on.

Days 4–6: absorb it in a sealed bag

1. Put the jacket in a large, clean bag or box that closes: a big storage bag, a garment bag you can seal, or a lidded plastic tub. This is for a few days only. Don’t store leather long-term in plastic.
2. Add an odour absorber in an open container or a breathable pouch, never touching the leather:
   • Activated charcoal (sold in pouches for shoes, cars and closets) is the strongest everyday option, and it is the material public health guidance names for removing odours from air.
   • Baking soda (sodium bicarbonate) in a shallow bowl or a sock tied shut is cheap and works on milder smells.
   • Unused coffee grounds work too, but can leave a coffee smell of their own.
3. Seal it and leave it for 2–3 days. Then air the jacket for a day and sniff again.

Don’t sprinkle baking soda straight onto leather. The powder is mildly alkaline and works into the grain, seams and suede nap. If you use it on a cloth lining, brush and vacuum it all out afterwards, and test a hidden spot first.

Day 7: treat the lining

The lining usually holds the most smell, and it is fabric, so you can treat it more directly.

1. Check the lining material on the care label. Most jacket linings are polyester, viscose, cotton or a blend.
2. Test first on a hidden spot such as the inside of a pocket bag.
3. Lightly mist the lining (not the leather) with one of these, from about 30 cm (1 ft) away, so it is damp, not wet:
   • Plain vodka or rubbing alcohol diluted with water. Alcohol evaporates quickly and takes some of the odour with it. Keep it well away from the leather: alcohol can lift dye and dry the finish.
   • White vinegar diluted with roughly equal parts water. The vinegar smell fades as it dries.
4. Hang the jacket inside out to dry at room temperature. Never use a hair dryer, a radiator or a tumble dryer.

Still smells? Repeat days 4–7 once. Two full rounds fix most second-hand and smoker’s jackets. If the smell is still strong after that, see “When to call a professional”.

Smooth leather, suede and shearling: what changes

Jacket	Safe extras	Avoid
Smooth leather (biker, bomber, blazer)	After deodorising, wipe the outside with a barely damp cloth, let it dry, then condition it. Conditioner replaces oils and leaves a neutral leather smell	Alcohol, vinegar or fragrance sprays on the leather itself; soaking
Aniline / “naked” leather	Airing and absorbing only; test any liquid with a drop on a hidden spot first	Any liquid on the outside; these finishes spot easily
Suede and nubuck	Air, absorb, then brush the nap with a suede brush to release trapped particles	Water, vinegar and alcohol on the outside; baking soda in the nap
Shearling (suede outside, wool inside)	Air with the fleece facing out; brush the wool gently with a wide-tooth comb or wire pet brush to open it up; absorbing in a sealed bag works well	Washing it yourself, steam, heat; soaking the fleece
Faux leather / PU	The lining steps, plus a wipe of the outside with a damp cloth	Heat; harsh solvents

Shearling deserves a word of its own: the wool side is a natural fibre with a huge surface area, and it holds smells well. Airing and absorbing help a lot, but a shearling coat that lived in a smoker’s house for years usually needs a sheepskin specialist. Our guide to what shearling is explains the different sides and finishes.

Mildew and mould smells

A sour, earthy smell, especially with white or greenish spots, is mould, not smoke. Deodorising won’t fix it, because the mould keeps making the smell.

For the full method (how to tell mould from harmless fatty spew, safety kit, HEPA vacuuming and when a jacket can’t be saved), see how to remove mold from a leather jacket. The short version:

1. Take the jacket outside and brush loose mould off with a soft brush, away from you.
2. Wipe the surface with a cloth dampened (not wet) in roughly equal parts water and white vinegar, as in our cleaning and conditioning guide.
3. Dry it at room temperature, then run the absorbing step above, then condition.
4. If the mould is in the lining or padding, keeps coming back, or the jacket is valuable, take it to a leather cleaner.

Then fix the cause: a damp closet, a plastic cover, or a jacket put away wet.

What never to do

• Don’t wash it in a machine or a tub. Water and agitation can stiffen, shrink and discolour leather, and a soaked shearling fleece takes days to dry (more in can you wash a leather jacket?).
• Don’t steam it or dry it with heat. Wet leather shrinks at much lower temperatures than dry leather, and the shrinkage is permanent.
• Don’t spray perfume, air fresheners or fabric refreshers on the leather. They mask the smell for a day, can leave spots on leather, and often mix with smoke to make it worse. If you use one at all, test it on the lining only.
• Don’t use an ozone generator at home. Connecticut’s Department of Public Health says ozone “is not effective at removing odor” at levels considered safe and can instead deaden your sense of smell. It also warns that ozone can damage certain plastics and rubber and recommends that ozone generators not be used in the home. Some professional restorers use ozone in controlled, empty rooms; that is not a DIY job.
• Don’t leave it in strong sun for days. A few hours of shade-and-breeze does more good with none of the fading.
• Don’t store it in a sealed plastic bag afterwards. The sealed bag is a 2–3 day treatment, not storage.

When to call a professional

Take the jacket to a leather specialist cleaner (not a general dry cleaner unless it says it handles leather and suede) if:

• the smell is still strong after two full rounds of the plan;
• it’s shearling that smells strongly of smoke or damp;
• there is mould in the lining or padding;
• the jacket is vintage, expensive or sentimental.

Ask what they will do and whether they deodorise the lining separately. Many specialist leather cleaners offer odour treatment as part of a clean. Ask for a price first; it varies widely by city and jacket type.

Buying second-hand? Check the smell before you pay

If you are shopping vintage or second-hand, smell is worth checking as carefully as the leather grade or the fit:

1. Sniff the lining, the underarms, the collar and inside the pockets, not just the outside.
2. Musty or light smoke: usually fixable with the plan above. A fair reason to ask for a lower price.
3. Strong, sour mildew with visible spots, or heavy old smoke that hits you from a metre away: fixable sometimes, with time or a professional’s help. Only buy if the price allows for that, or you’d be happy with a faint smell on damp days.
4. Heavy store “freshener” smell: ask yourself what it is covering.

Frequently asked questions

How long does it take to get smoke smell out of a leather jacket?

A fresh smell from one evening usually goes after 2–3 days of airing. A smoker’s or thrift-store jacket typically needs one or two rounds of the 7-day plan: airing, then a few days sealed with activated charcoal or baking soda, then a tested mist on the lining.

Does baking soda get the smell out of leather?

It helps, as an absorber placed next to the jacket in a sealed bag or box. Don’t sprinkle it on the leather itself: it’s mildly alkaline and works into the grain, seams and suede nap. Activated charcoal usually works faster on strong smells.

Can you put a leather jacket in the freezer to remove smell?

There’s no good evidence that freezing removes smoke residue, and a cold, damp freezer is a poor place for leather. Airing and absorbing work better.

Will the smoke smell come back?

A faint smell can return on damp, humid days, because moisture releases residue that dry air couldn’t. If it does, repeat the airing and absorbing steps. Each round usually leaves less.

Can I use vinegar on a leather jacket to remove smell?

Use diluted white vinegar (about equal parts water) on the lining, after a spot test, and on smooth leather only as a barely damp wipe for mould. Don’t use it on suede, nubuck or aniline leather, and condition smooth leather afterwards.

How do I get smoke smell out of a shearling jacket?

Air it with the wool facing out, comb the fleece gently, then seal it with activated charcoal for a few days. Don’t wash it at home. If a strong smoke or damp smell survives that, take it to a sheepskin or leather specialist.
