Cigarette smoke odor is persistent because smoke residue settles into dust, textiles, paint, wood, and air-handling surfaces. Ventilation and fragrance may reduce perception briefly, but a home with repeated exposure needs surface cleaning and sometimes sealing or replacement of heavily contaminated materials.
Remove ash, butts, and washable textiles
Start with active sources and items that concentrate odor. Wash curtains, bedding, and covers according to their labels and clean or replace small porous items that still smell after washing.
Clean settled dust and surface film
Vacuum with good filtration and clean walls, ceilings, doors, and furniture using compatible products. Residue may be heaviest near smoking areas and around return-air grilles.
Check filters and accessible ventilation surfaces
Replace filters in the heating and cooling system and in air purifiers, and clean accessible grilles. Duct cleaning is not automatically required in every case; it is better justified when visible contamination or internal residue is actually present.
Heavily contaminated walls may need a sealing primer
If cleaned walls still yellow or release odor, an appropriate stain- and odor-blocking primer may be needed before repainting. Do not paint directly over greasy residue because the new coating may adhere poorly.
