The short answer
Start with a Dry Sponge
Before you use any liquid, try a dry cellulose sponge. Gently wipe the soot from the wall in one direction. This lifts loose particles without pushing them into the paint. Work from the top down so you do not smear the residue.
If the sponge gets dirty, switch to a fresh one. Soot can be oily and sticky, so a clean surface helps. Stop if you see the paint smearing or the soot spreading. That is a sign the damage is deeper than the surface.
Mix a Gentle Cleaning Solution
For washable painted walls, mix a small amount of dish soap or a mild degreaser with warm water. Dip a soft cloth into the solution and wring it out well. Wipe the wall with a light touch, then rinse with a clean damp cloth and dry with a towel.
Avoid soaking the wall. Excess water can damage drywall or seep into cracks. Test the solution on a small, hidden area first. If the paint comes off or the color changes, stop and call the pros for advice.
Know When to Stop
Smoke damage can be stubborn. If the soot is thick, greasy, or has soaked into the wall, home cleaning might not be enough. Porous surfaces like bare drywall, wood, or textured plaster absorb smoke deeply. You might see stains return even after cleaning.
In that case, let the pros handle it. They have specialized tools and cleaning agents for deep smoke penetration. They can also assess if the wall needs sealing or repainting to lock in odors and stains.
Remember, your safety comes first. If you feel unwell from the smoke smell or cleaning fumes, step outside and get fresh air.
Deal with Lingering Odors
Cleaning the walls removes soot, but the smell can linger. Open windows and use fans to ventilate the room. Place bowls of white vinegar or baking soda around the space to absorb odors. Change them daily until the smell fades.
If you live in Layton, the dry climate can help with ventilation, but it will not remove the odor entirely. For persistent smoke smell, a professional may use ozone or thermal fogging treatments. These methods address the odor at the source, not just the surface.
Keep in mind that smoke odor can travel through walls and into insulation. You might need to clean or replace materials beyond the visible damage.
Protect Yourself While Cleaning
Wear gloves, a mask, and old clothes. Soot gets everywhere and can irritate your skin and lungs. Work in a well-ventilated area. Take breaks if you feel tired or dizzy.
Do not mix cleaning chemicals. Some products create harmful fumes when combined. Stick to one solution at a time. If you have health conditions like asthma, ask someone else to do the heavy cleaning or call the pros.
After cleaning, wash your hands and clothes separately. Dispose of used sponges and cloths in a sealed bag.

Can I use bleach on smoke-stained walls?
Bleach is not a good choice for smoke damage. It can damage paint and drywall, and it does not break down soot effectively. Stick to mild soap or degreasers. If the stain is stubborn, consult a professional before using strong chemicals.
Will repainting cover smoke stains?
Repainting might cover the stain, but it will not remove the odor. The smoke residue can bleed through the new paint over time. A professional can clean the surface, apply a sealing primer, and then paint to lock in the residue.
How long does it take for smoke smell to go away?
It depends on the severity and the materials affected. Light smoke may clear in a few days with ventilation and cleaning. Heavy smoke can linger for weeks or months. If the smell persists, professional treatment may be the only way to remove it completely.
