Yes, in most cases you can remove smoke smell from a house, but you have to remove the source rather than mask it. Start today with three steps: open windows for cross-ventilation, pull down and launder every washable fabric, and run an air purifier on its highest setting. Light, recent odours often clear within days. Heavier, long-term contamination usually needs a fuller plan and sometimes a professional clean.
TL;DR:
- Effective smoke odor removal requires thorough cleaning of fabrics, surfaces, and air filtration rather than masking smells with fragrances.
- Ventilating a property with cross-breezes and running air purifiers on high significantly reduces airborne smoke particles initially.
- Fabrics, carpets, and soft furnishings often need washing, steaming, or replacement if odors and saturation persist after cleaning.
- Hard surfaces and ceiling areas must be properly washed, sealed with an odour-blocking primer, and repainted for permanent odor elimination.
- Professional cleaning is recommended when odor endures after DIY efforts, especially for heavily stained walls, carpets, or in properties being prepared for sale.

Ventilate and circulate fresh air
Fresh air is the first move because it dilutes the airborne particles and gases that carry smoke odour before you even start scrubbing anything. Open windows on opposite sides of the room or house to create a through-breeze, and turn on extractor fans and ceiling fans to keep air moving rather than settling.
- Open opposite-facing windows for at least two hours on dry, breezy days.
- Run bathroom and kitchen extractor fans continuously while you clean.
- On cold or wet days, ventilate in shorter 20 to 30 minute bursts several times.
- Keep internal doors open so air moves room to room instead of pooling.
This step will not remove embedded residue, but it clears the air enough that you can judge how much odour is left once the breeze dies down, which tells you how much work the rest of the job actually needs.
Soft furnishings: launder, deodorise and decide what to replace
Fabric holds onto smoke longer than almost anything else in a room. Thirdhand smoke residue can stay in fabrics for months, and cotton releases far more nicotine and tobacco-specific compounds than polyester when it is washed, which is part of why a simple spray-and-go approach rarely works on curtains or bedding.
- Strip curtains, bedding, cushion covers and throws and wash on the hottest setting the fabric allows.
- Add a cup of white vinegar or half a cup of bicarbonate of soda to the wash alongside your usual detergent.
- For items that cannot be laundered, steam clean them or book a professional upholstery service.
- Check for yellowing, stiffness or a smell that survives a wash, which signals saturation rather than surface odour.
- Replace anything that fails that check, since heavily saturated fabric is often cheaper to swap than to keep treating.
Pro Tip: Air items outdoors on a warm day after washing. Sunlight and moving air finish off odours that a washing machine alone cannot fully clear.
Carpets and upholstery: absorbents, vacuuming and professional cleaning options
Carpets and upholstered furniture trap smoke the same way fabric does, just with more surface area and padding underneath. Bicarbonate of soda is the cheapest first line of attack.
- Sprinkle bicarbonate of soda generously over the whole carpet or sofa surface.
- Leave it for at least eight hours, overnight if possible, so it has time to absorb odour.
- Vacuum slowly in overlapping passes, since a quick pass leaves powder and odour behind.
- Follow with steam cleaning or hot-water extraction for carpets that still smell after vacuuming.
- Book a professional carpet cleaning service when staining or odour persists after one full treatment cycle.
Expect a noticeable reduction after this stage, but not always a complete fix on carpets that have absorbed smoke for years. At that point, replacement is often the more reliable outcome than repeated treatment.
Hard surfaces, walls and ceilings: cleaning, sealing and repainting correctly
Walls and ceilings absorb smoke residue into paint and plaster, which is why painting over a smoky wall without prepping it properly tends to fail within months as the smell works its way back through.
- Wash walls and ceilings with a solution of warm water, a few drops of washing-up liquid and a splash of white vinegar.
- Rinse with clean water on a separate cloth to avoid smearing residue back onto the surface.
- Apply an odour-blocking, stain-sealing primer before any repainting, since standard paint will not seal in nicotine residue on its own.
- Repaint once the primer has fully dried, following the manufacturer's recoat time.
- Replace skirting boards, doors or sections of plaster that remain discoloured or smell strongly after washing and priming.
This sequence, wash, seal, then paint, matches the approach recommended in general cleaning and health guidance for persistent smoke odour on hard surfaces.
Air cleaning and filters: HEPA, activated carbon and HVAC care
Once textiles and surfaces are treated, the air itself still needs attention. HEPA filters capture the fine particles smoke leaves behind, while activated carbon layers adsorb the gaseous compounds that cause the lingering smell. Smoke-removal guidance recommends purifiers that combine both, run on high initially and scaled to the room's square footage.
- Choose a purifier rated for the room size you are treating, not just the smallest unit available.
- Run it on its highest setting for the first 24 to 48 hours, then drop to a normal daily cycle.
- Replace carbon filters more often than the standard schedule suggests, since smoke saturates them faster than everyday dust.
- Have HVAC ducts inspected or cleaned if the smell returns whenever the heating or air conditioning switches on.
Keeping both filter types running together is what distinguishes genuine odour removal from a purifier that only clears visible dust.
Special treatments and what to avoid
Not every fix helps. Ozone generators are sometimes used in fire and smoke restoration, but industry guidance flags real respiratory risks and recommends strict exposure controls, with some professionals questioning whether the benefit outweighs the risk in an occupied home. Masking odours is just as counterproductive.
- Avoid ozone machines in any home where people or pets are present during treatment.
- Skip incense, plug-ins and heavy air fresheners, which cover the smell temporarily and add more volatile compounds to the air.
- Consider enzyme-based cleaners for biological odour breakdown on fabric and hard surfaces, an approach also used for other stubborn household smells such as pet odour and biological contamination.
- Leave thermal fogging to trained restoration technicians, since it uses heated deodorising agents that need controlled application.
When to choose a professional cleaning service
DIY handles most light to moderate smoke odour, but some situations call for a professional. Persistent smell after a full round of washing, vacuuming and ventilation is the clearest sign. So is heavy staining on walls or soft furnishings, a property going on the market, or a household with children, pregnant occupants or anyone with respiratory conditions.
- Odour that survives a complete DIY cycle usually means residue has reached padding, plaster or ductwork.
- Heavy nicotine staining on ceilings or walls often needs commercial-grade degreasers and sealing primer.
- Properties being prepared for sale benefit from a coordinated deep clean rather than piecemeal treatment.
Cleanny offers deep cleaning, carpet cleaning and upholstery cleaning, carried out by vetted, insured cleaners using eco-friendly products, with upfront pricing and a re-clean guarantee if the job falls short.
Pro Tip: Book a deep clean before repainting, not after. Painting over residue wastes the primer's sealing effect.
Resale and timing: what sellers should expect
Smoke odour puts off buyers before they even look at the rest of a property. A UK property report found that some buyers would reduce their offer for a smoke-affected home. Ventilation and a textile wash can show results within a day or two, but full remediation, including walls and carpets, needs one to two weeks. Tackle the smell before photos and viewings, not after an offer falls through.

FAQ
Can you ever get rid of smoke smell in a house completely?
Most smoke smell can be removed with thorough cleaning that targets fabrics, surfaces and air rather than masking the odour. Heavily saturated carpets, plaster or ductwork sometimes need replacement or professional treatment to fully clear, since thirdhand smoke residue can persist in porous materials for months.
How long does it take for smoke smell to go away in a house?
Light odour can noticeably reduce within a day or two of ventilating and washing fabrics. Full remediation, including walls, carpets and air filtration, typically takes one to two weeks, and some surface residues have been measured up to six months after a smoker quits in homes that were not deep cleaned.
What smell cancels out cigarette smoke?
No fragrance actually cancels out smoke, it only covers it temporarily and adds more compounds to the air. Bicarbonate of soda and activated carbon work by absorbing the odour-causing particles and gases rather than masking them, which is why cleaning guidance recommends them over air fresheners.
How can I instantly remove smoke smell?
There is no instant fix, but opening windows for cross-ventilation, running an air purifier on high and washing nearby fabrics gives the fastest noticeable improvement. For a lasting result, follow up with a deeper clean of carpets, upholstery and hard surfaces rather than relying on ventilation alone.
