What We Do

What Is Soot, and Why Does Wiping It Make It Worse?

Soot is the unburned carbon and condensed residue a fire leaves behind — a film of fine, oily, acidic particles that settles on every surface in the path of the smoke. It behaves nothing like dust. Dust sits on a surface; soot bonds to it, and because it is acidic it keeps working on the material underneath for as long as it stays there. Metal tarnishes, plastics yellow, grout and unsealed stone discolor, and paint takes a stain that deepens by the day.

The instinct after a fire is to grab a bucket and start wiping. That is the single most expensive mistake we see. Water and household cleaners dissolve the oily residue into a slurry that soaks into paint, drywall paper, wood grain, and fabric — and once it is in, it does not come back out. Surfaces that would have cleaned with a dry sponge become surfaces that need sealing and repainting, or replacement. Leave it, keep the furnace off so it does not spread further, and call.

The four residues, and why one cleaner never works

Dry soot — from a fast, hot fire of wood, paper, or natural fibers. Powdery, loose, and the easiest to remove: it lifts with dry chemical sponges and HEPA vacuuming before any wet cleaning touches the surface.
Wet soot — from a slow, smoldering, low-oxygen fire of plastics, foam, and synthetics. Sticky, smeary, and strongly odorous. It needs solvent-based cleaning and smears into a permanent stain if it is wiped with water. This is the residue an electrical fire leaves.
Protein residue — from burned food and grease. Nearly invisible, with a strong odor, and it yellows and etches finishes if left in place. Degreasing agents, applied carefully, not scrubbing. This is the kitchen fire residue.
Fuel-oil soot — from a furnace or boiler puffback. Greasy, black, and distributed through the ductwork to every room the system serves. It needs the duct system cleaned as part of the job. See puffback cleanup.

The biggest mistake Seth Saxton sees on smoke jobs is not matching the cleaning to how the smoke damage happened. Different fires leave different residue, and the method has to match that residue or the cleaning either fails or sets the stain.

Surface by Surface

How Is Soot Removed From Each Surface?

The order matters as much as the chemistry: dry removal first, everywhere, before anything wet touches a surface. Then each material gets its own treatment.

Walls and ceilings

Painted drywall is dry-sponged from the top down, then wet-cleaned with a residue-appropriate cleaner. Ceilings are the heaviest hit because smoke rises and stalls there. Flat and matte paints hold more residue than semi-gloss; textured ceilings are the hardest, and heavily smoked texture often has to be sealed and repainted rather than cleaned. Where a stain or odor remains after cleaning, the surface is sealed with a shellac- or oil-based primer before paint, so it does not bleed through.

Woodwork, cabinets, and doors

Finished wood cleans well if the residue has not been smeared into the finish. Unfinished wood — the inside of cabinets, closet shelving, exposed framing — absorbs soot and odor and usually needs sealing after cleaning. Cabinet interiors are a common miss; smoke gets in through the gaps around doors and drawers.

Metal, glass, stone, and tile

Metal fixtures, appliance fronts, faucets, and door hardware etch fastest and are cleaned first. Glass and glazed tile clean fully; unsealed grout and natural stone absorb residue and need specialized cleaning and often resealing.

Ductwork and the HVAC system

If the system ran, the duct interiors are coated and will re-release soot and odor every cycle. We clean the ducts ourselves as part of the job. The filter is replaced, and the furnace or air handler is inspected before it runs again.

Contents are packed out to our contents-cleaning partner; we clean the structure. Textiles go to a textile specialist, and we are honest about what is worth cleaning versus claiming.

Once the soot is off, the odor that remains in cavities and ducts is a separate step — gas-phase treatment, covered on our smoke odor removal page. Odor treatment on surfaces that still carry soot fails within weeks, which is why cleaning always comes first.

Step by Step

How Soot Cleanup Works

1
Stop the spread
HVAC shut down, HEPA air scrubbers running, containment set so soot stops migrating into clean rooms.
2
Identify the residue
Dry, wet, protein, or fuel-oil — identified room by room and documented for the claim; this decides the method.
3
Dry removal first
Chemical sponges and HEPA vacuuming on every surface before anything wet, so residue lifts instead of smearing.
4
Wet clean, seal, duct clean
Surface-matched wet cleaning, sealing where stain or odor remains, and the duct system cleaned so it can’t re-coat the house.

Direct Insurance Billing

We Handle Your Insurance, Start to Finish

Fire and smoke are named perils in the standard homeowners form (ISO HO 00 03), and newer editions specifically include puffback from a furnace or boiler. Coverage depends on your policy, so check it or ask your agent. We document the loss for your adjuster, and if it is a covered loss, we bill your carrier directly. Long-term cigarette smoke is not a covered loss. Scope is where claims fall short: soot reaches far past the visible stains, into ducts, cabinet interiors, and rooms that look clean. We document the residue type and extent room by room, write the Xactimate estimate your adjuster recognizes, and, if it is a covered loss, bill your carrier directly.

One call to (801) 948-2501 and the paperwork is our problem, not yours.

Straight Answers

Soot Cleanup Questions, Answered

Can I clean soot off my walls myself?

Please don’t — at least not with water or an all-purpose cleaner. Soot is oily and acidic, and a wet wipe dissolves it into a film that soaks into paint and drywall paper permanently. A wall that a dry chemical sponge would have cleaned in one pass becomes a wall that has to be sealed and repainted, or in heavy cases replaced. Leave it alone, keep the HVAC off, and call.

How fast does soot damage surfaces?

Soot is acidic and keeps discoloring finishes the longer it sits, so the sooner it is professionally cleaned, the more surfaces can be saved.

What are the different types of soot?

Four, broadly. Dry soot from a fast, hot fire of natural materials is powdery and lifts easily. Wet soot from a slow, smoldering fire of plastics and synthetics is sticky, smears, and smells strongly. Protein residue from a kitchen fire is nearly invisible but yellows finishes and holds odor. Fuel-oil soot from a furnace puffback is greasy and travels through the ducts. Each one is cleaned with a different method — using the wrong one sets the stain.

Does soot get into the ductwork?

Almost always, if the furnace or air handler ran. The return pulls soot into the system and the supply distributes it to every room it serves. Cleaning the rooms without cleaning the ducts means the first heating cycle re-coats the house. Keystone Restoration cleans the ductwork itself as part of the job, rather than subcontracting it.

Is soot dangerous to breathe?

Yes. The EPA notes that fine particles can get deep into the lungs, which is why we run air filtration while we work. Children, older adults, and anyone with asthma or heart conditions should stay out until cleanup and HEPA air scrubbing are done. We run air scrubbers from the first day on site.
