The short answer
Assess the Soot Type
Before you touch anything, figure out what kind of soot you are dealing with. Dry soot, like from a fast-burning fire, is powdery and smears easily. Oily soot, often from a slow-burning fire or candle, feels greasy and can be harder to remove.
If the soot is from a fire, it may contain acids that can damage wall surfaces over time. Check if the paint is still intact and if the wall is drywall, plaster, or paneling. Porous surfaces like unpainted drywall absorb soot and may need professional attention.
Gather Your Supplies
You will need a HEPA vacuum, a dry chemical sponge (also called a soot sponge), clean cloths, warm water, mild dish soap, and a bucket. For oily soot, have a degreasing cleaner on hand, but test it on an inconspicuous spot first.
Wear gloves and a dust mask to avoid inhaling soot particles. Open windows for ventilation. Do not use a regular vacuum without a HEPA filter, as it can blow soot into the air. Keep children and pets out of the room while you work.

Vacuum Loose Soot
Use a HEPA vacuum with a soft brush attachment to gently remove loose soot from the walls. Work from the top down to avoid dragging soot over already cleaned areas. Do not rub or scrub, as that can grind soot into the paint.
If the soot is dry, vacuuming may remove most of it. For oily soot, vacuuming still helps, but you will need a cleaning solution afterward. Be patient and go over each section a few times to pick up as much as possible.
Clean with a Sponge
For dry soot, use a dry chemical sponge. Gently wipe the wall in one direction, turning the sponge as it picks up soot. Cut off the dirty layer with a knife when it becomes saturated. Do not wet the sponge, as that can smear the soot.
For oily soot, mix a small amount of mild dish soap with warm water. Dampen a cloth, wring it well, and wipe the wall in a circular motion. Rinse with a clean damp cloth and dry immediately. Work in small sections to prevent streaks.
Know When to Call the Pros
If soot covers a large area, has soaked into the wall, or the wall is textured, cleaning can be tricky. The pros have specialty tools and cleaning agents that can safely remove soot without damaging the surface. They also handle the cleanup of soot from ducts and contents.
If you live in Layton and the soot is from a significant fire, consider hiring local water damage pros who also handle soot and smoke cleanup. They can assess the damage and recommend the right cleaning approach. For extensive soot, professional deep cleaning after disasters is often the safest route.

Can I use water on soot-covered walls?
Only if the soot is oily and the wall is painted. For dry soot, water can smear it and push it deeper into the surface. Always test a small area first. On porous surfaces like unpainted drywall, avoid water entirely.
What is a dry chemical sponge?
It is a sponge made of vulcanized rubber that lifts dry soot without water. You wipe the wall gently, and the sponge absorbs the soot. When the sponge gets dirty, you trim the surface with a knife to expose a clean layer.
Will soot staining come off the walls?
It depends on the wall material and how long the soot has been there. Fresh soot on painted walls often cleans up well. Older soot or soot on porous surfaces may leave a stain. If stains remain, you might need to repaint or have the pros clean the walls.
