TL;DR
Smoke odor is not a surface smell -- it is tar, resin, and microscopic particles that have settled into the fiber. The sequence that works is air the garment outdoors first, soak it in a booster such as white vinegar or an oxygen bleach solution, wash it warm, then smell it before drying. Heat sets smoke odor permanently, so drying too early is the mistake that makes it unfixable.
Why does smoke smell stick to clothes so hard?
Because smoke is not just an odor, it is physical material. Combustion produces tars, resins, and particles small enough to lodge inside the fiber structure and inside the tiny air spaces of a woven fabric. Those deposits keep releasing odor compounds for weeks. Fragrance sprays cover them; they do not remove them.
Different smoke, different difficulty
Campfire and wood smoke is the easiest. It is mostly particulate and it responds well to airing plus a single thorough wash.
Cigarette smoke is harder. Tobacco tar is sticky and resinous, and it binds tightly to fiber. It also carries nicotine residue that reacts and lingers -- the phenomenon sometimes called thirdhand smoke. Expect two or more rounds.
Structure fire smoke is a different category entirely. It contains combustion products from plastics, insulation, and household materials, and heavily exposed textiles often cannot be recovered at home. That is restoration work, and it belongs to a professional restoration company rather than a laundry routine.

Step one: air it out before you wash it
This step is genuinely important and people skip it because it takes time rather than effort.
Hang the garment outdoors, or in a garage or porch with strong airflow, for several hours to a full day. Moving air carries away the volatile compounds sitting loose on and in the fabric, and it reduces the load the wash has to handle. Direct sunlight adds ultraviolet exposure, which helps break odor compounds down.
Do not put smoky clothing directly into a hamper with clean laundry, and do not leave it in a sealed bag or a car. Contained, the odor transfers to everything nearby and concentrates.
If a load has been sitting damp as well as smoky, deal with the sour smell too -- how to fix mildew smell in a forgotten load covers that.
Step two: soak
Fill a basin or the machine with warm water and choose one booster.
White vinegar, about one cup per gallon. Acidic, and effective at neutralizing the alkaline compounds in smoke residue.
Baking soda, about a half cup in a full basin. Absorbs and neutralizes odor compounds.
Oxygen bleach, dissolved per package directions. The strongest option and safe on most cottons and synthetics. Not safe on wool or silk.
Use one, not several. Never combine vinegar with chlorine bleach, and never combine chlorine bleach with ammonia or any acidic cleaner -- those combinations produce toxic gas.
Soak one to eight hours depending on severity. Heavy cigarette exposure benefits from an overnight soak.
Step three: wash
Wash in the warmest water the fabric tolerates, with a full detergent dose and the longest cycle available. Warmth helps dissolve the tar and resin holding the odor.
Wash smoky items separately from everything else. Odor transfers between garments in a shared load, and you can turn one smoky shirt into a smoky load.
Add an extra rinse if the machine offers one. Residue left in the fabric holds odor.
Step four: smell it before it goes in the dryer
Push your face into the wet fabric and smell it directly. Wet fabric smells weaker than dry fabric, so if you can detect smoke in a wet garment, it is still substantially there.
If you smell anything, repeat the soak and wash. Do not dry it. Dryer heat drives the remaining compounds deeper into the fiber and sets them, and a garment dried with smoke still in it takes several times as much work to recover.
Once it passes the smell check, dry it outdoors if you can. Sun and moving air finish the job better than a dryer does.
For items that cannot be washed
Structured garments, suits, and coats. Air them out thoroughly first, then take them to a cleaner and tell them it is smoke. Solvent cleaning is effective on smoke residue, and cleaners have specific processes for it. Dry clean only versus dry clean recommended covers which items truly need it.
Leather and suede. Air out, then a specialty leather cleaner. Do not wet them.
Bulky items you cannot wash immediately. Seal them in a container with an open box of baking soda or a bowl of activated charcoal for a few days. This absorbs a meaningful amount of odor and buys time, though it is not a substitute for washing.
What does not work
Fabric refresher sprays. They add fragrance over the residue. The smoke returns as the fragrance fades, usually within a day.
Scent boosters and dryer sheets. Same problem, plus heat setting the odor. Whether scent boosters actually clean covers what they do.
Freezing. Does nothing for chemical residue.
A single normal wash. For anything beyond light campfire exposure, one cycle is not enough, and drying after one insufficient cycle is how garments become permanently smoky.
FAQ
Does vinegar get smoke smell out of clothes?
Yes, it is one of the most effective home options. Soak the garment in warm water with about one cup of white vinegar per gallon for one to eight hours, then wash warm. Never combine vinegar with chlorine bleach in the same load or container.
How long does it take to get campfire smell out of clothing?
Usually a single round: several hours of outdoor airing, a soak, and one warm wash. Wood smoke is mostly particulate and comes out more easily than tobacco smoke, which often needs two or three rounds.
Can smoke smell be removed after clothes have been dried?
It gets harder, because dryer heat bonds the residue into the fiber, but it is often still possible. Use a long oxygen bleach soak followed by a warm wash, and repeat. Some heavily exposed items never fully recover.
Why does the smoke smell come back later?
Because residue is still in the fabric and the wash only removed the surface layer. Odor compounds keep releasing as the material warms or takes on humidity. Always check the wet garment before drying, and repeat the soak if any smell remains.
Does baking soda remove smoke odor?
It helps, particularly as a soak additive and as a dry absorber for items you cannot wash yet. It neutralizes odor compounds but does not dissolve tar and resin, so it works best combined with a proper warm wash rather than on its own.
What about smoke smell in stored clothes?
Stored fabric that has picked up smoke plus stale air needs the same treatment plus a storage fix, since it will reabsorb odor if it goes back into the same closet. How to fix musty stored linens covers the storage side.
When the whole house is the problem rather than one task, recurring house cleaning services are the wider option.
Smoke removal is mostly about sequence and patience: air first, soak second, wash third, and smell it before the dryer.
