Quick answer

If your mattress smells like smoke, the tar and soot in smoke have settled into the fabric and foam. Strip the bed, air the mattress, vacuum it and leave a layer of baking soda on it for several hours. If a smoky smell remains, a smoke odor eliminator spray made for fabric breaks the odor down instead of covering it. A mattress that was in a fire should be replaced.

Free fix vs. permanent fix

Free fix · A day of waiting

Air it, baking soda, repeat

  • Strip the bedding and wash it hot
  • Air the mattress with windows open and a fan running
  • Sprinkle baking soda, wait 6 to 24 hours, then vacuum
  • Repeat once or twice

How long it lasts: Lifts a light smoke smell for good. Heavy or old smoke can return when the mattress warms up.

A smoke odor eliminator spray for fabric

Baking soda pulls odor from the surface but cannot reach deep into foam. An odor-neutralizing spray is made to bind or break up smoke compounds in fabric, which is why owners describe it as going after the smell and not hiding it. Mist it lightly and let it dry.

What to get: Smoke odor eliminator spray for fabric

How long it lasts: Often permanent on light smoke, since it treats the odor itself. Heavier smoke can take two or three rounds.

Why it happens

1

Tar and soot from smoking indoors

Cigarette smoke leaves a sticky tar film. It settles on fabric and sinks into foam, and body heat pulls the smell back out at night.

2

Smoke from a nearby fire or neighbor

Wildfire smoke, a kitchen fire or smoke drifting through shared vents can saturate soft furnishings like a mattress.

3

A used or secondhand mattress

A mattress from a smoker's home, a rental or a storage unit can carry years of smoke in its foam.

4

Warmth releasing the odor

Heat frees odor trapped in foam. The smell often seems stronger at night or on warm days, even after the bedding is washed.

Try this first (free)

Do these in order, starting with the simplest.

  1. Strip and wash everything

    Wash sheets, the mattress protector and pillowcases hot with detergent, and add a cup of white vinegar to the rinse if the care labels allow. Smoke clings to bedding, so wash it first.

  2. Air the mattress

    Tool used: Box fan

    Open the windows and aim a fan across the bare mattress for several hours. A dry, breezy day is best. Avoid leaving a foam mattress in strong sun for long, as heat can age the foam.

  3. Vacuum the surface

    Tool used: Vacuum with an upholstery attachment

    Go over the top and the sides slowly with the upholstery attachment to lift loose soot.

  4. Cover it with baking soda

    Tool used: Baking soda

    Dust a thin, even layer over the whole mattress. Leave it for 6 to 24 hours, then vacuum it up slowly. Repeat if the smell is strong.

  5. Treat what is left with a spray

    Tool used: Smoke odor eliminator spray for fabric

    Hold a fabric-safe smoke odor eliminator about a foot away and mist the surface lightly. Do not soak the mattress. Let it dry completely with the fan on before you make the bed.

When free fixes aren't enough

Baking soda and airing handle light smoke. If two rounds later the mattress still smells when it warms up, the smoke is deep in the foam. A targeted spray helps with moderate smoke when applied in thin passes with drying time between them. For tobacco from years in a smoker's home, or a mattress that was in a house fire, treatment may not fully work, and replacing it can cost less than months of trying. A mattress near a fire may also hold soot and burned-chemical residue, so do not sleep on it. If the smell is of burning plastic or something electric, unplug any electric blanket or heated pad right away and stop using it.

How we picked: How we picked: this page is based on mattress care guides, odor removal advice from cleaning and fire restoration groups, and what owners report in reviews of smoke odor sprays. We do not test products by hand.

Check the room, not just the mattress

Smoke settles on every soft surface. Curtains, rugs, pillows and the bedding all hold it, and they re-scent the mattress as the room warms. Wash what you can, air the rest, and wipe hard surfaces with a damp cloth. If you treat only the mattress, the room will put the smell back.

When the smoke comes from outside

If wildfire or neighbor smoke is the source, keep windows closed on smoky days, run an air purifier, and only air the mattress when the air outside is clear. Otherwise you are pulling more smoke in.

What to skip

Cover-up sprays, fresheners and ozone machines

Perfume sprays mask smoke for a few hours and then blend with it. Ozone generators can be harmful to breathe and can damage foam and rubber, so skip them in a bedroom.

Frequently asked questions

How long does it take for a mattress to stop smelling like smoke?
Light smoke can fade in a day or two of airing and baking soda. Deep, old smoke can take weeks of repeated treatment, and sometimes it never fully clears.
Does baking soda really get smoke smell out of a mattress?
It helps with light odor near the surface. It cannot reach deep into foam, which is why airing longer or using a fabric spray often follows.
Can I steam clean a mattress that smells like smoke?
It is better not to. Moisture can stay inside the mattress and grow mold. Dry methods and a light mist are safer.
Should I replace a mattress that smells like smoke?
Replace it if it was in a fire, if the smell remains after two weeks of treatment, or if it makes you cough. Otherwise, try the steps above first.
