Prep first
Before you start
- Smell the fish before you cook it, since fresh fillets should smell fresh and mild.
- Check whether your range hood vents outside or recirculates, because that decides how the filter gets cleaned.
- Clear loose debris from the stovetop and the cutting board before you start washing.
- Test any cleaner on a hidden spot first, especially on leather or fabric.
Fish smell hangs around because it builds up in places you don't clean every day, like the range hood filter, the cutting board and the fridge shelf. Fresh fish has little odor, and the fishy smell develops as it ages, so the smell usually traces back to a leftover or a neglected surface. Check those spots first before you spray anything.
Getting rid of fish smell after cooking starts in the kitchen, where most of it begins. Work through the fish-touched surfaces first, then the hood filter, and then the air in the room. Masking sprays only cover the smell, so skip them and fix the source instead.

5 steps
Step by step
Step 1 of 5
Remove the fish source
Start by throwing out any fish that smells strong, and check the fridge and freezer for leftover pieces and packages. Fresh fillets should smell fresh and mild, so a strong smell is a sign to throw it out.
Tip. Take out the trash too, so no fish is left sitting in the kitchen.
Step 2 of 5
Wash everything the fish touched
Wash utensils that touched raw fish in hot soapy water before you use them for cooked food. Then wash the counters, cutting boards and any other surfaces raw fish touched.
Step 3 of 5
Clean the hood filter and screen
Check whether your hood vents outside or recirculates, since that decides which filter you have. Wash metal filters in the dishwasher, or soak them in warm water with dish soap, scrub with a soft brush, rinse, and air dry on a towel. Clean the exhaust screen while the filter dries.
Tip. Clean the grease filter often to avoid grease buildup.
Step 4 of 5
Set out vinegar and baking soda
Set out partially filled saucers of white vinegar around the room, or boil 1 tablespoon white vinegar in 1 cup of water to eliminate cooking odors. Place a partially filled saucer of baking soda on the refrigerator shelf to deodorize it.
Careful. Use white vinegar only; colored vinegar can leave a stain.
Step 5 of 5
Air out the room
Run the exhaust hood, and if it doesn't vent outside, open the closest window and set a fan in it to push odors out. Keep the hood running while the air clears.
Tip. Start the hood before you cook and let it run several minutes after cooking ends to clear smoke and odors.
Careful. Strong cooking odors and smoke can irritate the lungs, so don't skip the airing.
What makes the job easier
Products that help
Plain white vinegar and plain baking soda cover most of this job, so skip scented sprays and anything sold as an air freshener.
OdoBan Odor Eliminator & Disinfectant Concentrate
How we picked these: each product is made for this kind of odor or surface, its maker doesn't warn against using it on fish smell, and its directions fit the steps above.
Finished? How does it look?
Nice work. Let it dry completely before you use it again.
How to tell it's really done →A faint smell often fades as everything dries and airs out; give it a day before a second round.
Find the guide for your stain →Heavy grime or a lingering smell usually needs a second round once it's fully dry.
See what to do for what you're seeing →When to call a professional →How to tell it's done
The kitchen should smell neutral, with no fishy smell at the stove, the fridge or the cutting board. The hood filter should be fully dry before it goes back in; if it still smells, wash it again and let it dry completely.
If there is a stain too
Related guides
A smell usually has a stain or a spill behind it. These guides cover the cleanup in detail:
What changes for yours
Adjust for where the smell is
Wood cutting board
A wood board soaks up fish flavor and odor, so it needs its own treatment. Rub it with kosher or table salt and a damp sponge, or rub it with lemon or lime quarters and salt, let it sit 2-3 minutes, then wipe it clean with a damp cloth.
Never use cooking oil on a wood board. Oil it every 3-4 weeks depending on use, and consider a protective wood-board cream before you prepare fish.
Ducted range hood
A ducted hood sends air outside, so the main job is keeping its washable metal filters clean. Wash them about every 3 months, and clean the exhaust screen often.
Start the hood before you cook fish and let it run several minutes after cooking ends to clear smoke and odors. Make sure the exhaust vents directly outside, since that is what lets it clear odors from the kitchen.
Recirculating range hood
A recirculating hood sends the air back into the kitchen, so its charcoal filter is what handles the odor. Charcoal filters can't be washed, so replace them about every 6 months with normal use, and clean the grease filter often to avoid grease buildup.
If the kitchen always smells like cooking or grease, a dirty filter may be the cause, so check it before anything else. If the hood doesn't vent outside, open the closest window and use a fan in it to push odors out.
Pans and cookware
Wash any pan that cooked fish in hot soapy water, the same way you would wash utensils that touched raw fish. Pan finishes need care, so check what the pan is made of before you choose a cleaner.
If your pan is stainless steel, keep detergents with bleach or peroxide away from it, since they can damage it. Household ammonia can damage stainless steel too, so skip it there.
Leather and upholstery
Leather and upholstery that isn't water-washable can't take most of the stronger cleaners people reach for. Keep alcohol and oxygen bleach off leather, since they can damage it.
If you don't know what the leather or fabric is made of, don't spray a liquid on it. Air the room out with the hood running and a window open, and test any cleaner on a hidden spot first.
Prevention
Keep the smell from coming back
If your hood has washable metal filters, wash them about every 3 months. If it recirculates, replace the charcoal filter about every 6 months with normal use, since it can't be washed.
Run the hood whenever you cook, starting it before you begin and letting it run several minutes after cooking ends. Store fresh fish in its original wrapper in the coldest part of the refrigerator and use it within one to two days, or freeze it wrapped tightly in cling wrap, then a freezer bag or foil.
Oil the cutting board every 3-4 weeks depending on use, and never use cooking oil on it. Keep the baking soda saucer on the refrigerator shelf to deodorize it.
Vinegar, baking soda, peroxide and more
Do home remedies get rid of the smell?
Many cleaners that work on stains don't help with fish smell at all. Only a couple appear in the steps, and the rest are either unnecessary here or unsafe on pans, leather or fabric.

What makes it worse
Mistakes to avoid
Don't rely on air fresheners
Most commercial air fresheners don't clean the air; they mask odors. Masking leaves the source in place, so the smell returns once the scent fades.
Don't mix vinegar and baking soda
Mixed in equal parts, they neutralize each other and lose their cleaning power. Use each one on its own, with vinegar in saucers or a simmer and baking soda on the fridge shelf.
Don't skip the range hood filter
A dirty hood filter may be the reason the kitchen always smells like cooking or grease. Clean it on schedule, even if the hood seems to be working.
Don't taste fish that smells off
Never taste food that looks or smells strange to check it. Fresh fillets should smell fresh and mild, so trust your nose and throw out anything that smells wrong.
Troubleshooting
If the smell comes back
Pick what you're seeing:
The kitchen smells like cooking days later
Check the range hood filter first, since a dirty one can keep the kitchen smelling of cooking or grease. Make sure the hood vents outside, and if it recirculates, replace its charcoal filter when it's due.
The fridge still smells fishy
Put a partially filled saucer of baking soda on the refrigerator shelf. Then check for fish stored longer than one to two days or wrapped loosely, and throw out anything that smells off.
The smell comes back in the air
Run the hood while you cook and for several minutes after. If the hood doesn't vent outside, open a window and use a fan in it to push odors out.
When to call a professional
If the smell hangs on after you've cleaned the hood, fridge and surfaces, a professional cleaner can check the vent system for a source you can't reach. Ask them to look at the vent and filter work specifically.
Questions
Does lemon juice remove fish odor?
Not for the whole kitchen, since lemon's use here is the wood cutting board with salt. The steps don't need it, and it should stay off marble, limestone and stainless steel finishes.
How do I remove fish odor from a cooler or container?
Wash it with hot soapy water, the same way you would wash utensils that touched raw fish. Let it air out fully before you use it again, and keep fish wrapped tightly so the smell doesn't build up.
How do I get seafood or shrimp smell out of the house?
Use the same steps as for fish, with extra attention to the wood cutting board and any utensils that touched the seafood. Wash those in hot soapy water before using them again, and then air the room out.
Why does my house smell like fish days after cooking?
Often a leftover source is still there, such as a dirty hood filter, a cutting board or fish that was stored too long. Fresh fish has little odor and the fishy smell develops with time, so it tends to show up later.
Can a ceiling fan or A/C help clear the smell?
Not with the hood running, since ceiling fans and A/C registers can create air currents that interfere with hood ventilation. Keep them from blowing across the cooktop, and rely on the hood and an open window instead.
Do I need to replace the range hood filter?
Only if it's a charcoal filter on a recirculating hood, which can't be washed and needs replacing about every 6 months with normal use. Washable metal filters stay in use and need cleaning about every 3 months.
