How to remove an unpleasant odor in the refrigerator: 12 proven methods and prevention

Even the most modern refrigerator with a system No Frost or Total No Frost can become a source of persistent unpleasant odor. Reasons range from spoiled food to bacteria growing in hidden corners. But regardless of the source, the main thing is to correctly determine how to wash the inside of the refrigeratorin order not only to mask the aroma, but to eliminate it forever.

In this article we will look 12 effective methods - from improvised means (soda, vinegar, coffee) to professional chemicals, and also tell you How to prevent the smell from reappearing. We will place special emphasis on hidden areas of the refrigerator (drainage hole, sealing rubber, back wall), which are often overlooked, but this is where the main dirt accumulates.

Important: if the smell appeared after a power outage or breakdown, first check the functionality of the equipment. In some cases (for example, if there is a freon leak), repairs may be required.

Why an unpleasant odor appears: 5 main reasons

Before you look, how to clean a refrigerator from smellyou need to understand its source. Most often the culprits are:

• 🍎 Spoiled products - even a small piece of meat or fish forgotten on a shelf can become a breeding ground for bacteria. It is especially dangerous if the product begins to rot in a closed container.
• 🧼 Inadequate hygiene - leftover food on the shelves, sticky stains from juices or sauces attract microbes. Even if you wipe down your refrigerator regularly, dirt may accumulate in the drainage hole or under the vegetable drawers.
• 🧊 Mold and mildew is a common problem in refrigerators with a drip defrost system. Moisture condenses on the back wall, creating ideal conditions for the proliferation of spores.
• 🔌 Equipment malfunctions —if the refrigerator does not freeze well (for example, due to a broken thermostat or compressor), food spoils faster. Also, the smell can come from drainage tubeif it is clogged.
• 🧀 Odor absorbers - paradoxically, some “fresheners” (for example, scented wipes) themselves begin to smell over time. The same goes for expired silica gel packets.

🔍 How to quickly determine the source? Unplug the refrigerator, take out all the food and smell every shelf, drawer and rubber seal. Often the smell is concentrated in one place - for example, under the bottom drawer for vegetables or behind a plastic panel on the back wall.

What you should not wash the refrigerator with: 4 dangerous mistakes

Not all detergents are suitable for fridge care. Some can not only make the smell worse, but also damage plastic or rubber parts. Here's what is strictly prohibited to use:

• 🧴 Chlorine-containing bleaches (for example, “Whiteness”) - they have an aggressive effect on plastic, causing microcracks in which bacteria then accumulate. In addition, chlorine itself has a pungent odor, which can be absorbed into the seal.
• 🧽 Abrasive powders (such as Pemolux) - scratch the surface, making it porous. Dirt subsequently gets clogged into these scratches, and the smell returns faster.
• 🌿 Essential oils in their pure form for example, tea tree or lavender oil. They can leave greasy stains and become a source of persistent aroma. Perhaps a few drops can be added to the water for the final rinse.
• 🔥 Hot water - due to a sharp temperature change, the plastic can be deformed, and the sealing gum will lose elasticity. The optimal water temperature for washing is 30–40°C.

⚠️ Attention: If your refrigerator has a display or touch buttons (for example, model Samsung Family Hub or LG InstaView), avoid getting moisture on the electronic panels. To clean them, use dry microfiber or special napkins for equipment.

Professional chemistry: what to choose for difficult cases

If home remedies do not help, it’s time to turn to specialized chemistry. The main thing is to choose products designed specifically for refrigerators, as they:

• 🛡️ Safe for food plastic;
• 🧪 Do not leave toxic residues;
• 🌬️ Neutralize odors rather than mask them.

The best options in terms of price/quality ratio:

• 🧴 Top House — spray for refrigerators with an antibacterial effect. Suitable for all types of surfaces, including stainless steel. Price: ~300 rub.
• 🧴 Unicum —removes persistent odors (including those from fish and spices), does not require rinsing. Price: ~250 rub.
• 🧴 Sano Refrigerator Cleaner —an environmentally friendly composition based on plant components. Ideal for families with children. Price: ~400 rub.
• 🧴 Dr. Beckmann - professional deep cleaning product, kills 99.9% of bacteria. Price: ~500 rub.

🔍 How to use? Apply the product to the surface, leave for 5-10 minutes (according to the instructions), then rinse with clean water. For the drainage hole, use a cotton swab soaked in the solution.

⚠️ Attention: If you are using a product with chlorine (for example, Domestos), be sure to wash it off after 1-2 minutes and ventilate the refrigerator for at least 3 hours. Chlorine may react with the plastic and increase the odor.

How to remove odor from the drain hole and other hidden areas

Even after thorough cleaning, the odor may remain if you have not treated 3 critical zones:

1. Drainage hole - located on the back wall of the refrigerator (in models with a drip system). Condensation flows there, and if the hole is clogged, the water stagnates, creating an ideal environment for bacteria.
2. Sealing rubber - crumbs, grease and mold accumulate in its folds. Often this is the source of the musty smell.
3. Rear wall - in refrigerators No Frost there is an evaporator that can freeze and “absorb” odors. Dust that gets through the ventilation grilles also accumulates there.

🛠️ How to clean the drainage hole:

1. Turn off the refrigerator and remove all the shelves.
2. Find the hole (usually at the bottom of the back wall) and carefully wash it warm water with soda, using a cotton swab or a soft brush.
3. To disinfect, pour a solution of vinegar (1:1 with water) into the hole and leave for 10 minutes, then rinse with clean water.
4. Check whether the water flows freely - if not, clean the hole with a wire (carefully so as not to damage the plastic).

🧽 How to wash the rubber seal:

• Remove the elastic (if possible according to the instructions for your model) and soak in warm water with soda for 15-20 minutes.
• Wipe the folds with a toothbrush dipped in vinegar or ammonia.
• Rinse thoroughly and dry. If the rubber band is not removable, treat it in place with a cotton pad.

What to do if the smell from the drainage hole returns?

If after cleaning the smell appears again, the problem may be a clogged drain tube (it leads to the condensate container on the back wall of the refrigerator). In this case:

1. Move the refrigerator away from the wall and find a container to collect water (usually a plastic tray above the compressor).

2. Remove it and wash with detergent.

3. Blow out the tube (you can use a bicycle pump or a can of compressed air).

If this does not help, the tube may be damaged - then a replacement will be required (it is better to contact service).

How to get rid of persistent odors: fish, onions, garlic, mold

Some aromas (especially fishy or onion) can be kept in the refrigerator for weeks. In such cases, “heavy artillery” and patience are needed.

1. Fishy smell

• 🐟 Rinse the refrigerator with a solution of vinegar (1:1), then place an open container with activated carbon (10-15 tablets) on the shelf for 12-24 hours.
• 🐟 Alternative - coffee beans (not ground coffee!). Place them on a saucer and leave for a day.

2. Smell of onion or garlic

• 🧄 Wipe all surfaces with a solution of lemon juice (1 lemon per 0.5 liters of water). The acid neutralizes sulfur compounds, which give a pungent aroma.
• 🧄 Place a glass of milk on the shelf - it will absorb the smell in 6-8 hours.

3. Musty smell or mold

• 🍄 Prepare a solution: 1 tbsp. l. hydrogen peroxide (3%) + 1 tbsp. l. vinegar + 1 liter of water. Treat all surfaces, paying special attention to the corners and elastic band.
• 🍄 After washing, wipe the refrigerator with a dry cloth and leave for a day with the door open, putting a bag of silica gel inside (available in boxes with shoes).

4. Smell of plastic (in a new refrigerator)

• 🆕 Wipe all surfaces with a solution of soda (2 tablespoons per 1 liter of water), then place a bowl of salt data-i="196">🆕 Air the refrigerator with the door open for 2-3 days before first use. salt on the shelf for 12 hours.
• 🆕 Air the refrigerator with the door open for 2-3 days before first use.

Prevention: how to prevent the appearance of odor

The best way to deal with an unpleasant odor is to prevent its occurrence. It is enough to follow a few rules:

• 📅 Regular cleaning — wash the refrigerator every 1-2 months (even if there is no visible dirt). Use a soda solution or special wipes for equipment.
• 🥩 Proper food storage:
  • Keep meat and fish in airtight containers or vacuum bags.
  • Pack fruits and vegetables in perforated bags or special containers with ventilation.
  • Store spicy foods (onions, garlic, spices) in closed jars.
• 🧊 Humidity control —in refrigerators with a drip system, regularly wipe the back wall from condensation. In models No Frost make sure that the ventilation holes are not blocked by products.
• 🌿 Natural odor absorbers - put on the shelf:
  • Bag with activated carbon (change once a month).
  • Cork lemon or orange (refreshes the air).
  • A bag with salt or soda (absorbs moisture and odors).
• 🔍 Check drainage - wash the drainage hole every 3 months to avoid stagnation of water.

📌 Additional life hack: If condensation often appears in the refrigerator, place a small container with riceon the bottom shelf. It perfectly absorbs excess moisture and prevents mold.

Frequently asked questions about the smell in the refrigerator

Is it possible to wash the refrigerator with laundry soap?

Yes, but with reservations. Laundry soap (72%) disinfects well, but it must be rinsed thoroughly so that no soap residue remains. The best option is to use it to wash removable shelves and drawers in the sink, and not to treat the internal walls. After washing, rinse the parts with water and vinegar (1:1) to neutralize the alkali.

Why does the smell return after a few days after washing?

Most likely, you have not eliminated the source of the problem. Frequent reasons:

• Forgot to wash drainage hole or the condensate container;
• Did not completely dry the refrigerator after cleaning (humidity promotes the growth of bacteria);
• Left a product in the refrigerator that has begun to spoil (check sauces, milk, sausages in vacuum packaging - they can spoil without visible signs).

Repeat cleaning, paying special attention to hidden areas, and use an odor absorber (for example, charcoal or soda).

How to remove the smell from the freezer chambers?

The freezer is washed according to the same principle as the refrigerator, but there are nuances:

1. Turn off the refrigerator and wait until it is completely defrosted.
2. Take out all the products and pack them in a cooler bag or wrap them in newspaper (this way they will not last longer will defrost).
3. Wash the camera with a solution of soda or vinegar (do not use hot water!).
4. To remove persistent odor, place on the shelf pieces of ice with lemon juice for 1-2 hours, then wipe dry.
5. Before turning on, ventilate the chamber for 30-60 minutes.

⚠️ Do not use abrasive products - they can damage the coating of the freezer.

Do air fresheners for the refrigerator help?

Fresheners (for example, "Boss" for the refrigerator or "Air Wick") mask the odor, but do not eliminate its cause. Moreover, their aroma can mix with a musty smell, creating an even more unpleasant “composition.”

Use air fresheners only after thorough cleaning as a temporary measure. It is better to give preference to natural absorbents: coal, soda or coffee beans.

What to do if the odor penetrates into plastic containers?

Plastic easily absorbs odors, but there are ways to eliminate them:

• Soak the containers in a solution of soda (2 tablespoons per 1 liter of water) for 12 hours.
• Wipe the inner walls toothpaste (especially if the smell is from fish or garlic).
• Place in a container newspapercrumpled into a ball and close the lid for a day - the paper will absorb the smell.
• For persistent odors, use hydrogen peroxide (3%) - apply to the walls, leave on 10 minutes, then rinse.

If all else fails, perhaps the plastic has absorbed the odor at the molecular level - in this case, it is better to replace the container.
