Best Candle to Remove Tuna Smell: Why Your Fix Failed and What Works Now

October 26, 2026 by MBur Candle Co.

Tuna smell comes from a gas called trimethylamine, and chemically it acts as a base, the opposite of the lemon juice cooks have squeezed over fish for centuries. Your nose can pick it up at very small amounts, far smaller than most kitchen smells need before you notice them. That is how a sandwich made at noon can still greet you at the front door at six.

That one detail also explains why the usual fixes keep letting you down. A spray of air freshener lays perfume over the gas while the gas keeps lifting off whatever it touched. What works is a short sequence that starts with plain kitchen chemistry and finishes with a clean flame, and that last step is where our pure beeswax candles, which burn with no paraffin soot and no toxic fragrance, earn their spot, keeping a cleaned room smelling fresh instead of covering what was left behind.

The smell starts inside the fish, long before you open the can

Ocean fish carry a compound called trimethylamine oxide, or TMAO, in their muscle. It helps them hold water in balance against the salt around them. On its own, TMAO has almost no smell.

Once the fish is caught, bacteria and the fish's own enzymes start turning TMAO into trimethylamine, which we will call TMA. TMA is the fishy smell itself. The longer the gap between the catch and your plate, the more of it builds up.

Canning cooks the tuna and seals that TMA in with the oil or water. Peel back the lid and it floods out at once. Drain the can over the sink and you have spread it across the basin and into the air above it.

So the smell you are fighting arrived fully formed, packed in with your lunch. The real question is why it stays so long after the can is in the trash.

Why ten minutes of tuna can outlast the whole afternoon

TMA is light, and it moves easily through the air. It also sticks. The molecule clings to porous things like a damp sponge or a cotton dish towel, then lets go slowly over hours.

Tuna oil makes this worse. When you mix tuna with mayo and wipe the fork on a towel, you leave a thin film of fish oil behind. Fats hold smells and release them slowly, so a towel hanging on the oven door can keep scenting the room long after the bowl is clean.

Because your nose senses TMA at such low levels, a small leftover source is enough to keep the smell alive. You can scrub the counter well and still catch tuna from one spot you missed. That is the gap the most common fix falls into.

The fix you already tried, and why it faded

Most people reach for one of two things. They open a window, or they bring out something sweet, like a plug-in or a vanilla candle from the hall closet.

The open window helps while it is open. Fresh air carries off the TMA floating in the room. Close it, though, and the towel and sponge go right back to releasing what they soaked up, and within the hour the smell is back.

The sweet scent fails in a different way. Perfume does nothing to the TMA itself, so your nose gets both smells at once. Vanilla or sugary bakery notes laid over fish read like a bakery next door to a fish market, and most people find that mix worse than the tuna alone.

The candle in the closet adds a problem of its own

Think about what that drugstore candle is made of. Crude oil goes to a refinery, where it is split into fuels like gasoline and diesel. A waxy residue is left near the bottom of that process. Refiners strip the oil out of it and bleach it white.

That residue is paraffin. It is petroleum waste, sold back to you in a jar.

Paraffin often burns incompletely, and the leftover carbon rises as black soot. That soot settles on walls and cabinets as a greasy film. Research has also shown that burning paraffin releases benzene, toluene, and formaldehyde into the room you are trying to freshen.

Many of these candles also use toxic fragrance containing phthalates, chemicals added to make a scent cling longer. In a kitchen, a soot film gives fish smell one more oily surface to hold onto. So the closet candle covers the tuna for an hour and leaves behind a surface ready for the next smell.

Now picture a different evening. The bowl is washed, the window was open while you made lunch, and all that remains is a faint trace you only catch when you walk back in. A candle made from one clean wax, with a scent that belongs in a kitchen, is the right tool for that moment, and it is the moment we had in mind for our Adi citrus beeswax candle: bright fruit over a flame that leaves no paraffin soot behind.

The answer: treat the gas, move the air, then light a clean flame

You can probably see where this is going. TMA is a base, so an acid takes it apart. When TMA meets the acid in lemon juice or white vinegar, the two react and form a salt.

That salt does not drift into the air the way TMA does. It stays put on the surface, and a rinse carries it away. This is the reason restaurants serve fish with a lemon wedge on the side, since the acid ties up the TMA before it reaches your nose.

So the best candle to remove tuna smell is the one you light after the source is treated: 100% beeswax, a wooden wick, and a bright citrus or green scent. The acid and fresh air clear the TMA. The candle keeps the clean room smelling fresh, and because it burns without paraffin soot, it adds nothing for the next smell to grab.

Every step before the candle is about finding and treating the source. The tricky part is that the source is rarely where you first look.

Where tuna smell hides, ranked from the spots you check to the one nobody does

This list runs from the places everyone cleans to the place almost nobody thinks about. The ones near the bottom are usually why the smell comes back after you thought you were done.

The can and lid. Even rinsed, a can in the kitchen trash keeps leaking smell. The lid holds oil on its underside, where a quick rinse rarely reaches.
The bowl and fork. Plain water mostly moves fish oil around. A drop of dish soap breaks it up so it actually washes off.
The sink drain. If you drained the can over the sink, tuna water may be sitting in the trap below it.
The sponge. It wiped the counter and the bowl, so it now holds a little of both. A damp sponge is one of the best places in the house for TMA to linger.
The dish towel. Cotton soaks up oil, and a towel on the oven door hangs right in the path of air moving through the room.
The cat's bowl. If the tuna was for the cat, the bowl on the floor keeps scenting the room for as long as it sits there, and a warm room speeds that up.
The range hood filter. If you seared a tuna steak or made a tuna melt, oily air passed through the hood. A greasy filter can send the smell back into the kitchen every time the fan runs.

Six steps that clear it, in the order that works

Order matters here. Clear the sources and the air first, and save the candle for last, once there is nothing left for it to cover.

Start the air moving before the lid comes off. Open a window and turn on the range hood or a fan first. Waiting until afterward gives oily air time to settle into curtains and towels. The EPA's pages on indoor air quality explain how bringing in outdoor air dilutes what builds up inside.
Bag the can and take the trash out. Put the can and lid in a small bag, tie it, and take it outside the same day. Seal and refrigerate any leftover tuna right away, and check the FoodSafety.gov cold food storage chart for how long it keeps.
Wipe with acid. Add a generous splash of white vinegar to warm water, or squeeze a lemon into it. Wipe the counter and sink, then rinse with clean water. The acid turns TMA into a salt that washes away.
Deal with the soft stuff. Put the dish towel in the wash and swap out the sponge. These two hold more smell than any hard surface in the room.
Simmer vinegar if the smell is heavy. Combine half a cup of white vinegar with one cup of water in a small pot. Keep it at a low simmer for about 15 minutes, or up to an hour of gentle steam for a strong smell, and stay in the kitchen while it runs. The acid in the steam meets TMA in the air the same way the wipe met it on the counter.
Light the candle once the room is clean. With the sources gone and the vinegar steam cleared, the candle has a fresh room to work in. If you are cooking a tuna steak, you can also light it as you start and keep it burning through cleanup, set well away from the stove.

What to burn once the room is clean

Scent choice matters as much as the wax. You want notes that read as fresh and sit well in a kitchen, and sharp citrus or green herbal notes do exactly that. Heavy vanilla and sugary notes push the other way, for the bakery and fish market reason above.

Adi, for a bright citrus finish

Think of that lemon wedge on the side of a fish plate. Adi carries the same instinct into the whole room. Its notes are Lemon, Orange, Grapefruit, Mandarin, Tangerine, Lime, Peach, and Agave.

The citrus opens bright and sharp, the way a kitchen smells right after you wipe it down with lemon. The peach and agave round off the edges, so it reads softer and warmer than a cleaning spray.

The wax underneath matters just as much. Adi is 100% beeswax, one wax with nothing blended in, burned on a wooden wick with phthalate-free fragrance and no chemical dye. It is hand poured in New York City. Beeswax has the highest melting point of the common candle waxes, so it melts slowly and the scent carries through a long, steady burn.

That slow melt is what gives a beeswax candle its reach. One customer, reviewing our Wine Down candle, described how far the scent travels:

"Absolutely obsessed with M Bur Candle Co my roommate and I own 6/8 of the scents! They smell up a WHOLE room during the burn & even a while after blowing them out. I won't buy other candles anymore, they're just that good"

Paige

That lingering scent after the flame is out is the part that matters in a kitchen. It keeps the room smelling fresh while you sit down to dinner.

Slice of Life, for a green kitchen garden scent

If citrus is not your favorite, go green. Our Slice of Life beeswax candle smells like crushing a sprig of mint over a cutting board. Its notes are Spearmint, Eucalyptus, Tomato Leaf, Anise, and Mint.

The tomato leaf gives it the snapped-stem smell of a summer garden. The mint and eucalyptus feel cool and clean in a warm kitchen, which suits a room where you cook most nights and want the air to smell like fresh herbs on the counter.

Picking the size for your kitchen

Size comes down to the room and how often you plan to light the candle.

The 12 oz size has two wooden wicks and burns 80+ hours. Two flames melt the surface faster and push scent farther, which makes it the right size for an open kitchen that runs into a living or dining area. It is also the one for a kitchen where fish is a weekly meal.

The 5 oz size has one wooden wick and burns 40 hours. It suits a small galley kitchen or a studio where the kitchen is one corner of the room. It also fits a home where tuna night only comes around now and then.

"But I burned a candle last time and the smell came back"

That usually means the candle went on before the sources were gone. A candle lit next to a towel full of fish oil is up against something that keeps releasing smell all evening. Run through the six steps first, and the same flame has a much easier job.

"My kitchen opens onto the living room"

Then the question is size and placement. Choose the 12 oz with two wicks and set it between the kitchen and the sofa, on a stable surface. Keep it away from the open window, since a strong draft pulls scent outside and makes the flame flicker.

"The tuna was for the cat"

Pick up the bowl and wash it as soon as the cat is finished, then wipe the floor around it with the vinegar mix. If you light a candle afterward, put it on a high surface the cat cannot reach. Never leave a lit candle alone in a room with a pet.

Getting the cleanest burn from your candle

A clean flame is the whole point of the last step, so a few habits help it stay that way.

On the first burn, let the melted wax reach the edge of the jar before you blow it out. This sets an even melt for every burn after it.
Trim the wooden wick to about 1/8 inch before each burn. A short wick gives a steady, clean flame.
Burn for no more than 4 hours at a time, then let the candle cool before relighting.
Keep the window open while you clean and simmer, then let the room settle before you light the candle.
Never leave a burning candle unattended.

Questions people ask about fish smell and candles

Why does tuna smell stick around so much longer than other food smells?

Tuna releases TMA, a gas your nose picks up at very low levels. It clings to soft, damp things like sponges and towels and lets go slowly. Treat those sources with acid first, then light a clean-burning beeswax candle to keep the room fresh.

Will a vanilla candle cover the fish smell?

Usually it makes the room smell worse. Sweet notes sit on top of the TMA, and you end up smelling both at once. For a kitchen, a bright citrus scent like Adi fits far better.

What should I burn if I don't like citrus?

Pick a green or tea scent instead. Slice of Life leans minty and garden fresh. Just to Clarify is calmer, with notes of Bergamot, Lemon, Orange, Green Tea, Black Tea, and Sandalwood.

Can I light the candle while I'm still cooking fish?

Yes, as long as it sits well away from the stove and anything that can catch, like paper towels. Light it when you start cooking and keep it going through cleanup. Any candle from our beeswax candle collection works the same way.

How long does a beeswax candle actually burn?

Our 12 oz size burns 80+ hours on two wooden wicks, and the 5 oz size burns 40 hours on one. Beeswax melts at a higher temperature than other candle waxes, so it burns slowly. You can see both sizes on the Adi candle page.

The candle for your kitchen after tuna night

Tuna smell lingers because TMA clings to soft surfaces and your nose catches it at tiny amounts. Clear the sources with acid and fresh air, then let a clean flame keep the room fresh. Done in that order, the smell stops coming back.

For an open kitchen you cook in every week, the 12 oz Adi ($65) is the one to keep on the counter. You walk back in and the room smells like lemon peel instead of lunch, which is the moment you know the cleanup worked. Its notes of Lemon, Orange, Grapefruit, Mandarin, Tangerine, Lime, Peach, and Agave sit cleanly beside a kitchen, and its two wooden wicks carry that scent across the room through 80+ hours of 100% beeswax.
