How to Clean Smoke Damage

Soot and Charring

Smoke damage causes black marks and discoloration to your walls and ceiling. Soot is the residue left by smoke. Charring is the actual burning of the paint. You should first assess the extent of the damage and determine whether cleaning is a reasonable option. It may be impossible to clean heavy soot and charring from flat-painted walls, and priming and re-painting may be your only option. There is more hope for satin or semi-gloss finishes, if the charring hasn’t gone too deep.

Smoke Odor

Aside from unsightly charring and soot build-up, smoke can leave an unpleasant odor that seems to cling to the walls. Smoke odors can be quite stubborn. Depending upon how strong the smoke odors are, one or more of these methods may prove helpful. Keep in mind, though, that if the smoke odor has permeated into your carpets, draperies, furnishings, etc. there is little that can be done to eliminate the smoke odor unless these items are removed or replaced.

  1. Vinegar: White vinegar cuts through odors naturally. Try wiping down furniture, washable walls, floors, etc. with white vinegar. Also, try placing several bowls of vinegar around the room with the smoke damage, leaving them there for several days. If you can’t stand the smell of vinegar either, try mixing a bit of lavender oil into the bowls to help cut the odor of the vinegar.
  2. Baking Soda: Baking soda is another natural odor-absorber. Try sprinkling liberal amounts of baking soda over furniture, floors, etc. Leave a few bowls of baking soda around the room for several days to help absorb the odors.
  3. Febreeze: Febreeze, a popular odor-reducing product sold in many stores, uses a chemical compound called cyclodextrin, a sugar-like substance that absorbs odors. Spraying the area down with Febreze may help to reduce the smoke odor.
  4. Activated Charcoal: This product, often used as a detoxifying agent, is also a natural odor absorbent. Placing bowls of activated charcoal (powdered form) around your room may help to absorb the smoke odors.
  5. Fresh Air: In the warmer weather, leave your windows and doors open as much as possible. Fresh air will eventually dissipate the smell of smoke.
  6. Ozone Generators: There are products on the market known as Ozone Generators which may help in reducing or even eliminating smoke odor from your house. Remember, though, that these expensive products, while effective in reducing the odor, will not eliminate it completely if the odor has permeated the carpets, draperies, furnishings, etc.
