Home remedies for removing tobacco smoke smells include airing out the space, cleaning the walls and deodorizing the carpets. Choose a day when the weather is agreeable, open the windows and doors, and leave them open as long as possible. If you cannot air out the room, try placing bowls of vinegar or coffee grounds around the space to absorb the smoke odor.
Tobacco smoke contains tar and nicotine that stick to the walls and stain the paint. These sticky substances cause the room to smell. Clean the walls using a solution of warm water and white vinegar in a spray bottle. For better cleaning power, mix 1/2 cup of ammonia in a gallon of water, and use the mixture to clean the walls. Keep the windows open when using ammonia to provide ventilation.
When cleaning the walls, clean the windows and mirrors to remove any smoke residue, and change light bulbs, which produce heat and vaporize the residue that sticks to them. Wash any curtains in the warmest water safe for the material.
Deodorize carpets using baking soda. Sprinkle the powder on top of the carpets, and allow it to stand for several hours before vacuuming. Replace the vacuum bag after picking up the baking soda. Change any filters in the air conditioner.
