The short answer
Safety First
Smoke residue contains soot, ash, and chemicals that can irritate your skin, eyes, and lungs. Open windows for ventilation and wear rubber gloves, safety goggles, and an N95 mask. If you feel unwell at any point, stop and see a doctor.
Before cleaning, turn off your HVAC system to avoid spreading soot through your home. Place drop cloths on the floor and cover nearby furniture with plastic sheeting. This keeps the mess contained and makes the job easier.

Dry Cleaning First
Do not start with water or liquid cleaners. Soot is oily and water can smear it deeper into the paint. Use a dry cellulose sponge or a vacuum with a HEPA filter and a soft brush attachment to lift loose soot from the walls.
Work from the top of the wall down, using light, even strokes. Change the sponge or empty the vacuum bag often so you do not redeposit soot. This dry step removes the bulk of the residue before any wet cleaning begins.
Wet Cleaning Solutions
For remaining stains, mix a small amount of mild dish soap or a degreaser with warm water. Test the solution on a hidden area of the wall first to check for paint damage. Use a clean sponge or cloth, working in small circles from the bottom up to avoid streaks.
Rinse the wall with a separate damp cloth and plain water, then dry it with a towel. Avoid soaking the wall, as excess moisture can damage drywall. For stubborn spots, a solution of vinegar and water sometimes helps, but always test it first.

Sealing the Walls
After cleaning, smoke odors and stains can still seep through paint. A shellac-based primer seals the wall and blocks those residues. Apply it with a roller or brush, and let it dry completely before repainting.
If the smoke damage is extensive or the walls are heavily stained, cleaning alone may not be enough. In that case, the pros often remove and replace affected drywall. This is especially true if the smoke came from a fire, as the wall material may be damaged.
When to Call the Pros
Some smoke damage is too deep for do-it-yourself cleaning. If the odor lingers after a thorough cleaning, or if the walls are covered with thick, sticky soot, professional help may be needed. The pros have industrial equipment and cleaning agents that handle heavy residue.
For homes in Rowlett, where humid conditions can make smoke odors worse, a thorough cleaning may require more than surface work. The pros can also clean your air ducts and upholstery, which trap smoke particles. If you live in Rowlett, consider asking about these extra steps.
Policies vary, and your insurer decides what is covered. Check your policy to see if smoke damage from a fire or other event is included.

Can I use bleach to clean smoke from walls?
Bleach is not a good choice for smoke residue. It can discolor paint and does not break down oily soot well. Stick with mild dish soap, degreasers, or a vinegar solution, and always test on a hidden area first.
How long does it take to clean smoke from walls?
The time depends on the size of the room and the level of soot. A small room with light residue may take a few hours. Heavy smoke damage can take a full day or more, especially if you need to seal and repaint the walls.
Will painting over smoke stains work?
Painting over smoke stains without cleaning first usually fails, as the soot bleeds through the new paint. A shellac-based primer seals the residue after cleaning. For heavy damage, the pros may need to remove the drywall instead.
