Fire and smoke

Kitchen fire cleanup: grease smoke, soot and odour

By ARO Restorations · Updated October 5, 2026

Short answer

Even a small kitchen fire spreads a greasy, strong-smelling residue through the house. Ventilate, switch off the furnace fan, throw out exposed food, and do not wipe walls with water. Grease and protein smoke need a degreasing cleaner, and the smell stays until every surface it reached is cleaned.

Why a small kitchen fire makes a large mess

Cooking is one of the leading causes of house fires. Most are put out quickly, and the flames may never leave the stove. The smoke does. It travels on warm air to every room, into cupboards and closets, and through the heating system.

Kitchen smoke is different from the smoke of burning wood or paper. It comes in two main kinds:

Grease smoke. Burning oil and fat produce a sticky, yellow-brown to black film. It bonds to cabinets, walls and ceilings, and smears when wiped with water.

Protein smoke. Meat, poultry, fish or beans burned in a pot or oven produce a residue that is almost invisible. There may be little or no black soot. The film is thin, greasy and amber, and the smell is intense and persistent. People often clean what they can see and cannot understand why the house still smells.

Once the fire is out

If the fire department attended, wait for their all-clear before going back in.
Do not use the stove, range hood or nearby outlets until they have been checked. Heat damages wiring and gas connections.
Open windows if the weather allows.
Switch off the furnace or air conditioning fan. A running fan draws residue into the ducts and spreads it to rooms the smoke barely reached. Replace the filter before turning it back on.
Take photographs of the damage before moving or cleaning anything.
Call your insurer or broker if the damage is more than a scorched pan.

What to throw out

Any food that was open or on the counter
Food in cardboard, paper, thin plastic or foil
Food stored in cupboards near the fire that smells of smoke
Anything exposed to heat, including cans and jars close to the fire. Heat can spoil the contents and break seals without visible damage.
Refrigerator and freezer contents if the power was off long enough for them to warm, or if smoke got inside
Anything touched by extinguisher powder or firefighting water
Medicines and cosmetics that were exposed to heat or soot

List and photograph what you discard. Spoiled food is commonly part of a claim.

What not to do

Do not wipe walls or ceilings with a wet cloth. Grease residue smears and is pushed into the paint.
Do not paint over it. Stain and smell come back through ordinary paint.
Do not use air fresheners. They add a second smell on top of the first.
Do not turn on a ceiling fan or a damaged range hood.
Do not wash smoke-damaged clothes in an ordinary cycle before checking. Heat from the dryer can set the smell.

How the cleaning is done

Dry soot first. Loose black soot is vacuumed with a HEPA vacuum and lifted with dry cleaning sponges before anything wet touches it.

Then degrease. Grease and protein films are removed with an alkaline degreasing cleaner, working in small sections and changing cloths often. Ceilings are done first, then walls from the top down.

Cabinets. Every surface is cleaned: doors, both faces, frames, shelves, the tops of upper cabinets and the undersides. Residue collects heavily on top of upper cabinets and above the fridge. Finished wood can usually be cleaned. Cabinets charred or blistered by heat are replaced.

Appliances. Outsides, insides, behind and underneath. A range hood and its duct hold grease and may need replacing after a fire beneath it. Appliances near the fire should be checked before use.

The contents of every cupboard. Dishes, pots and utensils are washed. A dishwasher handles most of it.

Soft furnishings and clothing throughout the house, if the smell reached them.

Ducts and the furnace filter, if the fan was running.

Sealing and painting. After cleaning, surfaces that were stained are primed with a stain and odour blocking primer before repainting.

Getting rid of the smell

Odour goes when the residue goes. Where a smell remains after thorough cleaning, restoration contractors use methods such as thermal fogging or hydroxyl generators, which reach the places smoke reached. These are finishing steps. They do not replace cleaning.

Ozone generators are sometimes offered for odour. Ozone is a lung irritant, and the space has to be empty of people, pets and plants while one runs and aired out afterwards.

Structural and heat damage

Look beyond the soot:

Scorched or blistered cabinets and countertops near the stove
A melted or warped range hood and microwave
Cracked tile or glass
Damaged wiring behind the stove and in the hood
Drywall that is charred, or soaked by firefighting water

Burned and heat-damaged materials are removed and rebuilt. Water used on the fire needs drying like any other water loss.

When to bring in a professional

The smoke reached several rooms
It was a protein fire and the smell will not shift
Cabinets, walls or wiring were damaged by heat
The furnace fan was running during or after the fire
A dry chemical extinguisher was used
Someone in the home has asthma or another breathing condition

Insurance

Fire and smoke damage are covered under standard home policies, including cleaning, repairs, spoiled food and, if the kitchen is unusable, additional living expenses, subject to your policy’s terms and deductible. Report the fire promptly and keep damaged items until the adjuster has seen them or agreed they can go.

Questions people ask

How do I clean up after a grease fire in the kitchen?

Vacuum loose soot with a HEPA vacuum, lift it with dry cleaning sponges, then clean every surface with a degreasing cleaner from the ceiling down. Do not start with a wet cloth.

Why does my house still smell after a small kitchen fire?

Burned food, especially meat, leaves a nearly invisible greasy film on every surface the smoke reached. The smell stays until that film is cleaned off everywhere, including inside cupboards and ducts.

Is food safe to eat after a kitchen fire?

Throw out anything that was open, stored in cardboard or thin plastic, exposed to heat or touched by extinguisher powder. When in doubt, throw it out.

Can I paint over smoke damage in my kitchen?

Not until it has been cleaned and primed with a stain and odour blocking primer. Ordinary paint lets both the stain and the smell come back through.

Does home insurance cover a kitchen fire?

Fire and smoke damage are covered under standard home policies, subject to the terms and deductible. That commonly includes cleaning, repairs and spoiled food.
