How to get rid of the unpleasant smell in the refrigerator: step-by-step instructions

An unpleasant odor in the refrigerator is a problem that almost everyone faces. Even with regular cleaning, odors from spoiled food, mold or plastic can linger for a long time on shelves, seals and ventilation grilles. But why does this happen, and how eliminate the smell in the refrigerator once and for all?

In this article we will analyze reasons for occurrence persistent “amber”, from rotten fish to the chemical taste of a new unit, and also give step-by-step instructions on cleaning - from quick methods with soda until thoroughly disinfected. We will pay special attention hidden sources of odor that are often forgotten (for example, a drainage hole or the back wall of No Frost). You will also learn how to prevent the problem from recurring using simple food storage rules.

Spoiler: in In 90% of cases, a combination of general cleaning, the correct placement of odor absorbers and humidity control is sufficient. But if the refrigerator “smells” even after washing, a breakdown is most likely to blame (more on this in the last section).

Why an unpleasant smell appears in the refrigerator: 7 main reasons

Before fighting the investigation, you need to find the source. Odor rarely occurs on its own; it is usually triggered by specific factors. Here are the most common:

• 🍳 Spoiled products. Even one rancid piece of meat or an open jar of sauce can “flavor” the entire refrigerator. Dairy products, fish and eggs are especially dangerous - they spoil faster than others.
• 🧊 Ice and mold. In models with a drip system (Indesit, Atlant), condensation accumulates on the back wall, which over time begins to smell damp. In systems No Frost mold can grow in the drainage hole.
• 🧽 Dirty shelves and containers. Juice stains, greasy stains, crumbs - all this becomes a breeding ground for bacteria. Plastic boxes for vegetables often absorb odors.
• 🔌 Faults. If the refrigerator does not freeze well (temperature above +5°C), food spoils faster. Also, the smell may come from burnt wiring or a freon leak (smells like “chemicals”).
• 🧴 Detergents. Aggressive chemistry (Domestos, Whiteness) leaves a persistent pungent odor that mixes with products.
• 🌡️ Impaired air circulation. If the refrigerator is packed to capacity, air does not circulate and odors “stagnate.” The same happens when products are incorrectly arranged (for example, open dishes on the top shelf).
• 🆕 New refrigerator. Plastic, polyurethane foam and rubber seals in the first weeks can emit a specific “technical” smell.

Interesting fact: in refrigerators with a system No Frost the smell spreads faster due to forced ventilation. And in models with Low Frost (for example, Liebherr) the problem is less common due to the uniform distribution of cold.

Preparation for cleaning: what needs to be done before cleaning

Before you grab the sponge, follow a few mandatory steps. This will save time and make cleaning more efficient.

1. Unplug the refrigerator. Simply unplug the plug from the socket - this way you will avoid the risk of electric shock and will be able to freely wash the back wall.
2. Take out all the products. Check expiration dates and throw away anything suspicious. Pack products that can be saved (cheeses, sausages) in airtight containers and place them in a cooler bag or on the balcony (if it’s cool outside).
3. Remove all removable elements: shelves, drawers, wire racks, egg tray. They need to be washed separately.
4. Prepare tools:
   • 🧽 Soft sponges and microfiber rags (abrasive sponges scratch plastic).
   • 🧴 Washing agent (soda, vinegar, a special spray for refrigerators are suitable).
   • 🧤 Rubber gloves (will protect the skin from chemicals and bacteria).
   • 🔦 Flashlight (to inspect the drainage hole and the back wall).

If there is ice in the refrigerator, let it melt naturally (do not chip it knife!). In models with No Frost defrosting is not required, but they also need to be washed at least once every 3 months.

⚠️ Attention: If the refrigerator makes a humming or crackling noise when turned off, do not try to disassemble it yourself. This may be a sign of a compressor malfunction - contact a service center.

How to remove the smell in the refrigerator: 5 effective ways

Now let's move on to the main thing - elimination of odor. Methods depend on the degree of "aroma" and its cause. Let's start with the simplest and safest.

1. Washing with soda solution (universal method)

Baking soda neutralizes sour and alkaline odors, kills bacteria and does not leave behind a chemical taste. Suitable for all types of refrigerators, including Samsung those with an ionic cleaning system.

Instructions:

1. Prepare a solution: 2 tbsp. spoons of soda per 1 liter of warm water.
2. Wipe all surfaces (walls, shelves, seal) with a soft sponge soaked in the solution.
3. For severe stains (grease, dried smudges), make a paste of soda and water, apply for 10 minutes, then rinse.
4. Wipe the refrigerator dry with a clean cloth.

2. Vinegar against persistent odors

Vinegar (9%) copes with mold, limescale and the smell of rotten meat. But you need to use it carefully - it can damage the rubber seals with frequent use.

How to use:

• Mix vinegar with water in a 1:1 ratio.
• Wipe all surfaces with the solution, paying attention to the corners and drainage hole.
• After 5 minutes, rinse with clean water and wipe dry.

For disinfection, you can leave a saucer with vinegar (undiluted) in the refrigerator for 12 hours. But don’t forget: the vinegar smell itself is persistent, so ventilate the refrigerator after the procedure.

3. Lemon juice for freshness

Lemon not only masks odors, but also kills bacteria thanks to its acid. Suitable for new refrigerators with a “plastic” aroma.

Method of application:

• Squeeze the juice from 1 lemon, mix with 200 ml of water.
• Wipe the shelves and door with the solution.
• Put lemon slices on a saucer and leave in the refrigerator for a day.

4. Activated carbon (odor absorber)

Charcoal absorbs odor molecules like a sponge. This is a temporary solution, but it will help you “survive” the time until general cleaning.

How to use:

• Crush 10 tablets of coal, put in a bowl.
• Place the bowl on the middle shelf of the refrigerator.
• Change coal every 2-3 days.

An alternative to coal is special absorbers (for example, Bork K700 or Topperr 3104). They work for up to 3 months and take up little space.

5. Coffee beans (express method)

Coffee absorbs odors no worse than coal, and also leaves a pleasant aroma. Suitable for refrigerators where a lot of spices or fish are stored.

Instructions:

• Pour fresh coffee beans into a small cup.
• Place on the top shelf (there is stronger air circulation).
• Change the beans once every a week.

Important: use only natural beans, not instant coffee - it will not give an effect.

Deep cleaning: how to get to hidden sources of odor

If the smell remains after washing, the problem lies in hard-to-reach places. They are often overlooked, but this is where the most dirt and bacteria accumulate.

1. Drainage hole

In refrigerators with a drip system (Bosch, Gorenje), condensate flows into the drainage hole on the back wall. If it becomes clogged, the water stagnates and begins to smell.

How to clean:

• Find the hole (usually at the bottom of the back wall).
• Take a cotton swab or cocktail straw, wrap it with a rag soaked in soda solution.
• Carefully clean the hole with rotational movements.
• Rinse with water from a syringe.

2. Sealing rubber

Crumbles, grease and mold accumulate in the folds of the rubber seal. This is one of the main reasons for the persistent odor.

Cleaning:

• Wipe the gum with a toothbrush dipped in vinegar solution.
• For disinfection, use hydrogen peroxide (3%).
• Wipe dry and apply a thin layer of silicone grease (will extend the life of the seal).

3. Ventilation grilles (No Frost)

In refrigerators with a system No Frost (LG, Samsung, air circulates through ventilation grilles on the rear wall. They need to be cleaned at least once every six months.

How to do this:

• Turn off the refrigerator and remove all shelves.
• Remove the protective fan cover (usually secured with latches).
• Vacuum the grilles or wipe them with a damp cloth.
• Make sure that the fan blades rotate freely (if not, lubricate them with equipment oil).

4. Containers for vegetables and fruits

Plastic boxes absorb odors the most. They need to be washed separately.

Method:

• Soak the drawers in warm water with baking soda for 30 minutes.
• Clean with the hard side of the sponge (but not with a steel wool!).
• Rinse vinegar solution for disinfection.
• Dry in air (not in the refrigerator!).

If the drawers are yellowed or covered with cracks, replace them. Microcracks accumulate bacteria that cannot be washed out.

What to do if the smell comes from the freezer?

In the freezer, the smell usually appears due to improper packaging of products (for example, fish in plastic without sealing) or defrosting. To eliminate it:

1. Defrost the chamber (if there is ice).

2. Wash the shelves and walls with a solution of soda and ammonia (1 teaspoon of ammonia per 1 liter of water).

3. Check whether the food in the lower drawers has spoiled (the temperature is higher there).

4. After washing, put a bag of baking soda or activated carbon in the freezer for 12 hours.

What you should not use to clean the refrigerator: 4 prohibited products

Not all detergents are safe for the refrigerator. Some can ruin the plastic, leave a persistent chemical odor, or even cause food poisoning.

Remedy	Why not use	What to replace
Chlorine (Whiteness)	Corrodes plastic, leaves a pungent odor that is absorbed into products. Dangerous for the respiratory tract.	Hydrogen peroxide or soda
Abrasive powders (Pemolux)	They scratch the surface, bacteria accumulate in microcrackslater.	Dishwashing gel or liquid soap
Scented sprays	They mask the smell, but do not remove its cause. They can give products a chemical taste.	Natural absorbents (coffee, coal)
Hot water (>40°C)	Deforms plastic, can damage seal.	Warm water (up to 30°C)

⚠️ Attention: If you use a steam generator to clean the refrigerator, keep the nozzle at least 20 cm from the surface. Hot steam can melt the thin plastic of the shelves (especially in budget models). data-i="215">or Indesit or Birusa).

Expert tip: if you often store fish or seafood in the refrigerator, put a bay leaf at the bottom of the drawer for them - it neutralizes the fishy smell.

When a smell is a sign of a breakdown: what to do?

If you have tried all the methods, but the smell remains, the problem may be technical. Here are the most common malfunctions and their symptoms:

• 🔥 Freon leak. "chemical" or sweetish gas. The refrigerator does not freeze well, the compressor works without stopping.
• 🔌 The compressor winding is burnt out. data-i="244">. Smell of dampness, water under the vegetable drawers, ice on the back wall.. There is a strong burning smell, the refrigerator may turn off or not turn on at all.
• 🌬️ Clogged drainage system. The smell of dampness, water under the vegetable drawers, ice on the back wall.
• 🦠 Mold in the evaporator. Black spots on the back wall (in models No Frost), persistent smell of rot.

What to do:

1. If it smells like burning or chemicals - turn off the refrigerator immediately and call a technician. This is dangerous to health!
2. If the drainage is clogged. try cleaning it yourself (see the section on deep cleaning).
3. If there is mold on the back wall, wash it with hydrogen peroxide and dry it with a hairdryer (at minimum power).
4. If you suspect a freon leak or a compressor breakdown, do not try to repair the refrigerator yourself - contact a service center.

⚠️ Attention: If the refrigerator is used and the smell comes from the inside (for example, from plastic or insulation), it is almost impossible to get rid of it. In such cases, it is easier to replace the unit.

The cost of repair depends on the breakdown. For example, cleaning the drainage will cost 1,000–1,500 rubles, and replacement. compressor - from 5,000 ₽. Check the exact prices in the service centers of your city.
