Smoke decides what survives a house fire, not the flames. In most residential fires the burn is contained to one area, and everything else in the house is damaged by smoke residue, heat and the water used to put it out. Contents cleaning is the process of going through every item in that house and deciding, item by item, whether it can be restored or has to be replaced.
That decision is not made on sentiment. It is made on three things: what the item is made of, what kind of smoke reached it, and whether restoration costs less than replacement. Understanding how it works helps you push back when a call goes the wrong way.
Smoke Is Not One Thing
Four types of residue behave completely differently, and the type dictates the cleaning method.
Wet smoke comes from low-heat, smouldering fires burning plastics and rubber. It leaves a sticky, black, smearing residue with a strong odour. It is the hardest to remove and it penetrates deeply, because the low heat gives it time to settle into surfaces.
Dry smoke comes from fast, high-temperature fires burning paper and wood. The residue is powdery and easier to lift, but the heat drives it into porous surfaces and it works its way into cracks and voids.
Protein residue comes from kitchen fires, usually cooking oil or meat. It is nearly invisible, discolours paint and varnish, and the odour is severe and persistent. People routinely underestimate a kitchen fire because so little of the damage is visible.
Fuel oil soot comes from furnace puff-backs. It coats everything in the house through the duct system in minutes.
A restoration technician identifies the type before touching anything, because using the wrong method makes the damage permanent. Wiping wet smoke with a dry sponge grinds it into the surface. Wiping protein residue with water sets it. This is the main reason “I’ll just clean it myself while I wait” costs people items that were salvageable.
The Triage: How Items Get Sorted
Contents get inventoried and photographed, then sorted into three groups.
Restorable on site. Hard, non-porous items with light residue. Furniture with sealed finishes, appliances, metal, glass, ceramics, sealed hardwood. These get cleaned in place or in a staging area of the house.
Pack-out. Items needing specialist equipment go to a facility. Ultrasonic cleaning for hard goods with detailed surfaces, ozone or hydroxyl chambers for odour, textile-specific processes for clothing and soft furnishings, dedicated processes for electronics and documents. Pack-out means everything is inventoried, barcoded, transported, cleaned, stored, and returned after the structure is repaired.
Non-salvageable. Items where cleaning either cannot work or costs more than replacement. These get documented in detail for the insurance claim, because the documentation is what gets you paid for them.
The salvage decision is largely about porosity. A material that absorbed smoke is far harder to clean than one that smoke sat on top of.
| Category | Usually restorable | Usually total loss |
| Furniture | Sealed hardwood, metal, glass, leather with light exposure | Upholstered pieces with wet smoke saturation, particle board that swelled |
| Clothing and textiles | Washable fabrics, most dry-clean-only items | Anything scorched, melted, or with heavy wet smoke on delicate fabric |
| Electronics | Devices with residue on the exterior only | Anything smoke got inside, or that was powered on during the fire |
| Documents and photos | Freeze-dry and digitisation recover a surprising amount | Charred or fully saturated paper |
| Food | Nothing sealed in glass or unopened cans | Everything else, including anything in the refrigerator |
| Mattresses and pillows | Rarely | Almost always |
| Cosmetics and medication | Nothing | All of it |
Do not keep food, medication or cosmetics that were in a fire. Sealed packaging does not make them safe. Heat degrades medication and smoke residue penetrates most packaging.
The Odour Problem
Contents that look clean and still smell are the most common complaint after a fire, and it happens because odour molecules are far smaller than soot particles. Surface cleaning removes what you can see and leaves what you can smell.
Real odour removal on contents uses one of a few processes: ozone treatment in a sealed chamber (effective, but the item must be unoccupied and off-gassed afterward), hydroxyl generators (slower, safe around occupied space), thermal fogging (recreates the particle behaviour of smoke so the deodorant reaches the same voids the smoke did), or sealing, where the item cannot be cleaned any further and the residual odour gets encapsulated.
If an item comes back smelling faintly of smoke and then smells strongly again three weeks later in warm weather, the odour was masked rather than removed. Heat and humidity reactivate residue that was not fully addressed. Say so and get it re-treated. We go deeper on this in how to get rid of smoke odour after a fire in Branson, MO.
Your HVAC system is part of this. Smoke travels the whole duct network in minutes and turning the system on after the fire redistributes it into every room. The ducts get sealed off immediately and cleaned as part of the air duct cleaning scope within the fire job.
What the Insurance Side Looks Like
Contents are covered under Coverage C on a standard homeowners policy, typically at 50% to 70% of the dwelling coverage. Two things determine whether you get paid properly.
Whether you have replacement cost or actual cash value. Actual cash value pays depreciated value, which on a seven-year-old sofa is a fraction of what a new one costs. Replacement cost pays what it costs to buy the equivalent today, usually in two steps: depreciated value first, and the remainder once you actually replace the item and submit the receipt.
Whether the inventory is complete. The contents inventory is the claim. Every non-salvageable item needs a description, an age, a condition, and a value. This is tedious and it is where most homeowners lose money, because items get forgotten and forgotten items do not get paid.
Photograph everything before anything moves. Do not throw away non-salvageable items until the adjuster has documented them. Keep every receipt for temporary living expenses. The mistakes that cost the most are laid out in 8 insurance mistakes that cost Branson homeowners thousands after a fire.
The Water Damage Nobody Plans For
Fire suppression puts a large volume of water into the structure, and then the contents sit in it. A fire on a Tuesday afternoon produces water damage that starts growing mold by Thursday.
This is why fire restoration and water damage work happen at the same time rather than in sequence. Extraction and drying start immediately, before contents cleaning finishes, because the 24 to 48 hour window for water damage restoration does not pause for the fire investigation. Contents left in a wet building for a week are lost to mold whether or not the smoke damaged them.

What You Should Not Do Yourself
- Do not wipe soot off walls or upholstery. Dry wiping wet smoke embeds it permanently.
- Do not run the HVAC.
- Do not use a household vacuum on soot. Standard filters pass fine particulate straight back into the room.
- Do not plug in or power on any appliance or electronic device that was in the fire, including things that look fine.
- Do not wash smoke-damaged clothing in a home machine. It sets the residue and contaminates the machine for every load after.
- Do not throw anything away before it is documented.
Frequently Asked Questions
How long does contents cleaning take after a fire?
On-site cleaning of a lightly affected room runs a few days. A full pack-out for a significant residential fire runs 4 to 12 weeks, because contents come back after the structure is repaired. Ask for the inventory list and the expected return window in writing at the start.
Can smoke-damaged clothes be saved?
Most washable clothing and most dry-clean-only items can be restored using processes designed for smoke residue. Home laundering usually cannot do it and often sets the odour permanently. Scorched, melted, or heavily wet-smoke-saturated items on delicate fabric are generally a loss.
Does insurance pay for contents cleaning?
Yes, contents cleaning falls under Coverage C on a standard homeowners policy. Whether you receive replacement cost or depreciated value depends on your policy type. The payout depends on the quality of the inventory, so treat that document as the most important paperwork in the claim.
Should I clean anything myself while I wait for the restoration company?
No. The single most common way salvageable items become total losses is well-meaning cleaning with the wrong method before the residue type has been identified. Photograph, do not touch.
