Tobacco smoke particles are very small and can penetrate most things which is the reason the smell is so hard to get rid of. Keep the home very well ventilated by opening all windows so that fresh air will flow through the home. Place odor absorbers such as baking soda and coffee grounds in different rooms.
Nicotine leaves an oily, brown residue which adheres to everything. It is likely you will see nicotine on light bulbs which, when turned on, will heat up and diffuse the smell into the air. It is a good idea to replace them or give them a through clean. Any blinds that may have been left behind should be taken down, soaked in a tub, given a good scrub and then hung up to dry. Detergents containing ammonia are good for removing nicotine from hard surfaces, but it is not a good idea to use them on wooden surfaces. Any air conditioner unit filters or HVAC filters should be replaced.
Removing nicotine odor from a carpet is, unfortunately, very tough. It is usually best to replace the carpet. Before you put down new carpet, however, clean and dry the under flooring thoroughly. Painting walls is something you will most probably need to do but, this doesn’t always get rid of nicotine which can seep through the paint.
Following these simple suggestions will help to make your home fresh again.
