The short answer
Assess the Damage First
Before you touch anything, look closely at the walls. Smoke damage can be light surface soot or deep into the paint and drywall. If the walls are heavily coated or the smoke smell is strong, cleaning may not be enough, and you might need to repaint or replace drywall.
Check whether the walls are painted, wallpapered, or bare drywall. Painted surfaces are easier to clean, while wallpaper can absorb smoke and may need replacement. Also, turn off the HVAC system to avoid spreading soot through your home.
Dry Cleaning Removes Soot
Use a vacuum with a soft brush attachment to gently remove loose soot from the walls. Work from the top down to avoid streaks. Do not rub, as that can grind soot into the surface.
After vacuuming, use a dry chemical sponge (available at hardware stores) to wipe the walls. This sponge lifts soot without water. Cut or tear the sponge to a fresh surface as it gets dirty. This step is crucial for preventing smearing.
- Always wear gloves and a mask to avoid inhaling soot.
- Protect floors with drop cloths or plastic sheeting.
- Remove outlet covers and switch plates for thorough cleaning.
- Work in small sections to track your progress.
- Test a small hidden area first to ensure the method is safe.
- Ventilate the room with open windows and fans.
Wet Cleaning for Remaining Stains
For stains that remain after dry cleaning, mix a small amount of mild dish soap or a specialized smoke cleaner with warm water. Dampen a sponge or cloth, wring it out well, and wipe the walls gently. Avoid soaking the wall, as excess water can damage drywall.
Rinse the walls with a separate clean, damp cloth to remove any soap residue. Change the water frequently. After cleaning, dry the walls with a towel or let them air dry. If the smell persists, you may need to seal the walls with a primer before repainting.
Dealing with Stubborn Odors
Cleaning the surface often removes visible soot but not the odor. Smoke can penetrate deep into paint, drywall, and insulation. After cleaning, place bowls of white vinegar or activated charcoal in the room to absorb smells. Baking soda also works.
If the odor remains after a few days, consider an ozone generator or a professional odor treatment. For extensive smoke damage, especially after a fire, the pros have specialized equipment to neutralize odors at the source. Policies vary, and your insurer decides what is covered. In such cases, you might also need to check with your insurance company about coverage for cleaning or restoration.
When to Call the Pros
You can handle light smoke damage on your own, but heavy or widespread damage is a different matter. If the walls are covered in thick, sticky soot, or if the smoke smell has permeated the entire house, professional help is wise. The pros have industrial-grade cleaners and equipment to restore walls and other surfaces.
Water damage often accompanies smoke damage, especially if a fire was extinguished with water. If you notice warped drywall, peeling paint, or mold growth, address those issues first. A water damage inspection can identify hidden problems. For help, you can look into on-site contents cleaning for your belongings or water damage inspection services.

Can I use bleach to clean smoke off walls?
Bleach is not effective for smoke residue and can damage paint or drywall. Stick to mild detergents or specialized smoke cleaners. For tough stains, a dry chemical sponge works better. Always test any cleaner on a small area first.
Will smoke damage come back after cleaning?
If you don't remove all soot and odor, it can resurface, especially when the wall heats up. Proper cleaning and sealing with a primer can prevent this. If the odor persists, you may need professional treatment to reach deeper layers.
How do I clean smoke damage off textured walls?
Textured surfaces like popcorn ceilings or knockdown walls are harder to clean because soot gets into the texture. Use a soft brush attachment on your vacuum, then a damp sponge. In some cases, repainting or replacing the texture is the only real fix.
