How to Remove a Fish Smell from a Refrigerator

Co-authored by James Sears

Last Updated: May 24, 2024 Fact Checked

The key to getting rid of a fish smell in the refrigerator is to empty the fridge and clean everything thoroughly. Then, use deodorizing products like baking soda, fresh coffee grounds, and crumpled newspaper to absorb leftover smells and get rid of the bad odors. Preventing fish smells is always the easiest approach, however, and you can do this by keeping all containers and bags tightly sealed, and by using ingredients before they go bad.

- Store it in coolers with ice packs
- Transfer it to a friend’s or neighbor’s fridge
- Leave it outside if it’s cold enough
2
Throw out tainted or rotten food. To ensure that the fish smell, or some other bad smell, doesn’t come back when the fridge is clean, locate the source of the smell and throw it out. While you're at it, throw out any food that’s gone bad, moldy, or rotten.^{[2]

- Smell every morsel of food in the fridge to check for fish smell as well. Items that weren't sealed and stored properly could have picked up the odor. Throw out anything that smells like fish.

Our Expert Agrees: Completely empty the fridge of all food. Throw away what you don't need, and see if you can identify the source of the smell.

Unplug the fridge. Getting rid of a fish smell in a refrigerator means some serious cleaning and airing out, and you don’t want to waste electricity while you do this. The best way to conserve electricity is to unplug your fridge once all the food is out.^{[3]

- Once you turn the fridge off, make sure you leave the doors open until it has completely defrosted, otherwise you could get mold.
4
Remove the drawers, shelves, and racks. Fish smell could have permeated the entire fridge, and the best way to get rid of it is to clean every surface. Fridge drawers, shelves, and racks are removable, and they’ll be much easier to clean if they're out of the refrigerator.^{[4]

- To keep these items out of the way, place them on the counter or on top of the fridge until you're ready to tackle them; try to stay organised and separate the ones you have cleaned by putting them back in the fridge.

1
Clean the refrigerator with soap and water. Fill a bucket with hot water. As the water is running, add about five drops of a liquid dish detergent. Swish the water around so suds form. Dip a sponge or cloth into the soap and water. Wring out the excess, and clean every inch of the interior surface of the fridge and freezer with the soap and water solution.^{[5]

- Re-soak and wring out the sponge frequently as you clean.
- When you're finished, fill a bucket with plain water. Use a clean sponge to wipe down the surfaces with the clean water.

Mix a disinfectant cleaning solution. There are a number of cleaning solutions you can use to clean your refrigerator, and most of them are basic household cleaning products. Depending on what you have available and your preferences, you can mix in a bucket:^{[6]

Disinfect the refrigerator and freezer. Dip a sponge or cloth into your cleaning solution. Wring out the excess. Inside the fridge and freezer, wipe the sides, top, bottom, and any shelving, trays, and other surfaces. Dip the sponge back into the cleaning solution frequently to keep it saturated.^{[7]

Expert Trick: If you've cleaned the refridgerator thoroughly and there's still a smell, generously apply white vinegar to any surfaces inside of the fridge.
Use a dry microfiber cloth, rag, or towel to wipe down all the interior surfaces of the refrigerator and freezer. This will help prevent water spots from forming, and speed up the air-drying process.
5
Air out the fridge and freezer. When the fridge and freezer have been thoroughly cleaned and wiped with water, leave the doors open and let them air out. You may need to tie the doors to something nearby to secure them in the open position. Air out the fridge and freezer for at least two hours, and as long as two days if you can.^{[8]

- When the doors are open, don’t leave children and pets unattended in the room to prevent them from getting stuck.
6
Clean and disinfect the drawers, shelves, and racks. Follow the same process for the drawers, shelves, and racks that you used for the rest of the fridge. Start by cleaning the surfaces with a soap and water mixture, and then wipe them with water. Wipe the surfaces with the disinfectant solution, followed by water. Finally, rinse the components under running water.^{[9]

- When you're finished, set the drawers, shelves, and racks aside to air dry. Leave them out of the fridge while it airs out.

Absorbing Excess Odors

1
Assemble and plug in the refrigerator. When the refrigerator and freezer have had sufficient time to air out, return the drawers, shelves, and racks to their original positions. Plug the appliance back in and let it cool down.
- Most refrigerators will need about six hours before they're at the correct operating temperature, and up to 24 hours before they're ready for food.
2
Place an odor-absorbing material in the fridge and freezer. An odor absorber will help remove any traces of fish smell that may still be lingering. Place the odor absorber in the fridge as soon as you turn it back on. Close the doors and leave the odor-absorber inside for 24 hours before replacing the food. Odor-absorbers you can use include:^{[10]

- Baking soda sprinkled on two large plates. Place one plate in the fridge and one in the freezer.
- Two bowls filled with fresh coffee grounds. Place a bowl in the fridge and in the freezer.
- Newspaper sheets crumpled up and stuffed into the open spaces of the fridge and freezer.
- Bowls filled with lighter-fluid free charcoal. Place one bowl in the fridge and one in the freezer.
3
Return foods to the chilled fridge and freezer. After 24 hours, pull the odor absorber out of the refrigerator and freezer. Return the food you’ve had stored to the fridge. Once the fridge is organized, you can put a bowl or plate of baking soda or coffee grounds back into the fridge.
- If you continue to use baking soda or coffee grounds as odor absorbers in the fridge, replace the odor absorber with a fresh batch every month.
4
Prevent future smells. There are a few ways you can keep your fridge clean and odor-free, and one of the most important is to clean spills immediately. You should also use foods before they go bad, and throw out foods as soon as they start to go off. Another important element in fighting fridge odors is storing foods properly:^{[11]

Question

What if I did all of this and I still have a fish smell?

Community Answer

I had this problem and tried all of the above without success. Eventually found that the plastic strips clipped onto the edges of the glass shelves were hiding dirt that I hadn't got to. I removed all the plastic and recleaned. No more smells.
