How to remove an unpleasant odor from the refrigerator quickly and efficiently: 12 working methods

An unpleasant smell in the refrigerator is a problem that every second home cook faces. It appears suddenly, penetrates into food and spoils your appetite, and getting rid of it is sometimes more difficult than it seems. In most cases, not only expired products are to blame, but also improper operation of equipment, accumulation of condensate or even bacterial contamination seals.

In this article we will analyze unique methods of eliminating odors for refrigerators with the No Frost system, drip defrosting and old models with manual defrostingand also tell you how to prevent their occurrence in future. All methods have been tested in practice and do not require the purchase of expensive products - we only use what is at hand.

Important: if the smell appeared after a power outage or a long period of inactivity of the refrigerator, the reasons and solutions will be different - read about this in a separate section section.

Why an unpleasant odor appears in the refrigerator: 5 main reasons

Before dealing with the effect, you need to understand the cause. In 90% of cases, the following are to blame:

• 🍎 Expired or improperly stored products —especially fish, meat, dairy products and fruits with a high sugar content (bananas, apples).
• 💧 Accumulation of condensate in the drainage hole or on the back wall (relevant for models with a drip system, for example, Indesit or Atlant).
• 🦠 Bacteria and mold on sealing rubber, shelves or in hard-to-reach places (a common problem in refrigerators Samsung with system Twin Cooling).
• 🧊 Improper defrosting - if the ice thawed at room temperature and not in a cool place.
• 🔌 Power outage - even 2-3 hours without cold is enough for food to begin to spoil.

Curious fact: in refrigerators with a system No Frost (for example, LG or Bosch) the smell appears less often, but if it occurs, it is more difficult to get rid of it due to the closed air circulation system. Special methods will be required here, which we will discuss below.

⚠️ Attention: If the smell is similar. on burning or chemicals, immediately unplug the refrigerator! This may indicate a compressor malfunction or a freon leak. In this case, professional diagnostics are needed.

What to do if the smell remains after cleaning?

If after deep cleaning the smell is still it is felt that the problem may be in:

1. Drainage system —clean the tube with a wire or rinse with a solution of soda and citric acid (1:1).

2. Compressor —if it smells like burning, you need diagnostics at a service center.

3. Plastic parts —some types of plastic (especially in older models) absorb odors. In this case, only replacing shelves or drawers will help.

How to remove specific odors: fish, onions, chemicals, burning

Some odors require a special approach. Here are proven solutions for the most difficult cases:

🐟 The smell of fish or seafood

The fish smell penetrates deeper than others due to the high content of amines. To eliminate it:

• Wipe all surfaces with a solution of vinegar (1:1 with water) or citric acid (2 tablespoons per 1 liter of water).
• Place on shelves crusts orange or grapefruit -citrus fruits neutralize the fishy aroma.
• Place an open jar of tomato juice tomato juice on the bottom shelf for 12 hours.

🧅 Smell of onion or garlic

Onions and garlic contain sulfur compounds, which remain in the refrigerator for a long time. Ways to combat:

• Wipe the shelves with a solution salt and vinegar (1 tbsp. salt + 1 tbsp. vinegar per 1 liter of water).
• Put on the shelves dry tea bags (black tea without additives) for 2-3 days.
• Use coffee grounds - it absorbs sulfur compounds.

🔥 Smell of burning or chemicals

If the refrigerator smells of burning, this may be a sign of a malfunction. But if the smell appears after washing with aggressive detergents, do the following:

• Rinse all surfaces soda solution (3 tablespoons per 1 liter of water) 2-3 times.
• Put on shelves activated carbon or charcoal (sold in pet stores) for 12 hours.
• Ventilate the refrigerator with the door open throughout the day.

⚠️ Attention: If a burning smell appears for no apparent reason (you did not wash the refrigerator with chemicals or cook fried food nearby), do not turn on the equipment before checking the electrical system. There may be problems with the compressor or wiring.

Prevention: how to prevent odors from appearing in the refrigerator

The best way to deal with odors is to prevent them from appearing. Here are 8 rules that will help keep things fresh:

• 🥩 Store food in containers. This is especially true for meat, fish, cheeses and fruits. Use containers with silicone gaskets - they are more airtight.
• 🧊 Regularly defrost the refrigerator. For models with No Frost - once every 6 months, for drip models - once every 3 months.
• 🧽 Wash the shelves and drawers every month with a solution of soda or vinegar.
• 🍋 Use natural odor absorbers: lemon slices, orange peel or bags of rice.
• 🌡️ Control the temperature. Optimal: +2…+4°C in the refrigerator and -18°C in the freezer. At higher temperatures, food spoils faster.
• 🚫 Do not store in the refrigerator onions, garlic, bananas, bread (except rye) and open canned food.
• 🔄 Check expiration dates once a week. Expired foods are the main cause of odors.
• 💨 Ventilate the refrigerator once a month: leave the door open for 10-15 minutes (after unplugging).

For For refrigerators with a function Air Filter (for example, Samsung RB37J5240SA) it is enough to change the carbon filter once every 3 months - it automatically absorbs odors. In models without this function, you can install magnetic odor absorber (sold in hardware stores).

Common mistakes when eliminating odor (and how to avoid them)

Many housewives make mistakes that only aggravate the problem. Here's what you can't do:

• 🧴 Use air flavors. They mask the smell, but do not remove its cause. After a while, the smell will return with a vengeance.
• 🧼 Wash the refrigerator with bleach or bleach. They leave a toxic odor and can damage the plastic.
• ☀️ Dry the refrigerator in direct sunlight. This leads to deformation of the seal and yellowing of the plastic.
• ❄️ Put hot foods in the refrigerator. Steam promotes the formation of condensation and the spread of odors.
• 🔌 Turn on the refrigerator immediately after washing. Let it dry for at least 30 minutes, otherwise moisture will cause mold.

Another common mistake is to ignore drainage hole. If it is clogged, water accumulates at the bottom of the refrigerator, which leads to mold and a persistent damp smell. Clean it at least once a month!

FAQ: Answers to frequently asked questions

Can I use perfume or perfume to eliminate odor?

No! Perfumes contain alcohol and synthetic fragrances, which can react with plastic and leave an even more persistent odor. In addition, the aroma of perfume will mix with the smell from the refrigerator, and you will get an unpleasant “chemical” mixture.

Why does the smell return after cleaning after a couple of days?

This means that the source of the smell has not been eliminated. The most common culprits are:

• Mold in the drainage hole or on the back wall.
• Dirty seal (it needs to be removed and soaked in a soda solution).
• Products that have already begun to deteriorate, but this is not visible from the outside (for example, cheeses or sausages in a vacuum packaging).

Repeat cleaning, paying special attention to these areas.

How to remove the smell from the freezer?

The freezer is cleaned using the same methods, but there are nuances:

1. Thaw it completely (at least 6-8 hours).
2. Wipe all surfaces with a solution of vinegar or alcohol (they do not freeze at low temperatures).
3. Use gel odor absorbers (for example, Topperr or Bork) - they work even at sub-zero temperatures temperatures.
4. Store food in double bags (for example, meat first in cling film, then in a zip bag).

Help Are there store-bought odor absorbers (for example, “Cinderella”)?

Yes, but their effectiveness depends on the type:

• Carbon absorbers (for example, "Cinderella") - they remove odors well, but require monthly replacement.
• Ionizers (for example, Xiaomi Viomi) - kill bacteria, but cannot cope with strong odors of fish or onions.
• Gel absorbers (for example, Topperr) - universal, but more expensive.

For the best effect, combine them with regular cleaning.

What to do if odors penetrate into plastic containers?

Plastic absorbs odors more strongly than other materials. To eliminate them:

1. Soak the containers in a solution of soda (4 tablespoons per 1 liter of water) for 12 hours.
2. Wipe the internal surfaces paste of soda and hydrogen peroxide (1:1).
3. Rinse with vinegar (1:1 with water) and dry in the sun (UV rays kill bacteria).
4. If the smell remains, it is better to throw away the container, especially if it is old (plastic deteriorates over time and releases toxins).
