An unpleasant smell in the refrigerator is a problem that almost everyone faces. It appears suddenly: either because of a fish forgotten on a shelf, or because of a leaking bag of cheese, or simply “by itself” after long-term use. The main thing is not to ignore this signal. The smell not only spoils the appetite, but may also indicate the growth of bacteria, mold or malfunctions of the ventilation system.
In this article we will analyze causes of odorsfrom simple (expired food) to hidden (pollution of the drainage system). And then - 10 working methods eliminate them: from folk remedies (soda, vinegar, coffee) to professional absorbents and cleaning techniques. All methods have been tested on refrigerators of different brands - from budget ATLANT to premium Liebherr.
We will pay special attention two critical points: how to avoid the reappearance of the smell and when to contact a service center. For example, if an unpleasant “aroma” returns 1-2 days after cleaning, the problem may lie in a compressor failure or a freon leak - and neither soda nor lemon will help here.
Why there is a smell in the refrigerator: 5 main ones reasons
Before starting to eliminate it, it is important to understand the source of the problem. A smell rarely occurs “just like that” - it is usually preceded by one or more reasons:
- 🍎 Expired or improperly stored food. Especially “fragrant” are fish, meat, dairy products and fruits (bananas, apples). Even sealed packaging does not always save: for example, meat can leak odors when damaged. Expired or improperly stored products; vacuum bags; vacuum bags. If the refrigerator is not washed at least once every 1–2 months, a sticky coating of bacteria and food debris will form on the walls and shelves. It becomes a “magnet” for odors. vacuum bags with meat can leak odors when damaged.
- 🧼 Untimely cleaning. If the refrigerator is not washed at least once every 1–2 months, a sticky coating of bacteria and food debris will form on the walls and shelves. It becomes a “magnet” for odors.
- 💧 Clogged drainage system. Water flowing down the rear wall (in models with
No Frost) can stagnate in the drainage hole, causing a putrid odor. A common problem is clogging of the drainage system. Appears in door seals, on rubber gaskets or in hard-to-reach corners (for example, under vegetable drawers). The risk is higher in refrigerators Samsung RB30J3 And Indesit DF 4180. - 🧊 Mold or mildew. Appears in door seals, on rubber gaskets or in hard-to-reach corners (for example, under vegetable drawers). The risk is higher in refrigerators with
Direct Cooldue to high humidity. - ⚙️ Technical faults. If the smell reminds fumes, plastic or chemicals, this may indicate overheating of the compressor, a freon leak, or melted insulation. Requires urgent diagnostics!
Interesting fact: in 80% of cases the products are to blame, but in 20% - the design features of the refrigerator. For example, models with fresh zones (type BioFresh v Liebherr) require more frequent cleaning due to high humidity in the compartments.
Preparing the refrigerator for cleaning: 5 mandatory steps
Before you begin to eliminate the smell, the refrigerator must be properly prepared. By skipping even one of the steps, you risk wasting your time:
- Turn off the power. Remove the plug from the socket or turn off the circuit breaker on the panel. This is important not only for safety, but also for resetting temperature sensors (in models with electronic control type Bosch KAN92VI30).
- Take out all the products. Check expiration dates and throw away anything suspicious. Products in glass jars (jams, pickles) can be left - they rarely become a source of odor.
- Remove all removable elements: shelves, drawers, grates, trays. They need to be washed separately in warm water. Some models (for example, LG GC-B247SLUV) have special grooves - remember their location so as not to break them during assembly.
- Wipe the seals. Rubber gaskets on the door often accumulate dirt and moisture. Use a soft brush or cotton swab dipped in soapy water.
- Let the refrigerator “ventilate”Leave. open the door for 15–20 minutes - this will help remove some of the odors and reduce the humidity inside.
If the refrigerator is equipped with a system No Frost, after turning off the power, water may flow from the drainage hole - this is how condensation is removed. Place it under it. a rag or tray.
☑️ Preparing for cleaning
Top 5 folk remedies for eliminating odor
Folk methods are good for their accessibility and safety (do not contain aggressive chemicals), however, their effectiveness depends on reasons for the smell:
- 🍋 Lemon juice or lemon wedges. Suitable for light food odors. Absorbs (fish, onions, garlic). Cut the lemon in half, place on the shelf and close the refrigerator for 3-4 hours. The acid neutralizes amines - the compounds responsible for the “fishy” smell.
- ☕ Natural coffee (beans or grounds). Absorbs persistent aromas (smoked meats, spices). Place the grounds on a saucer and leave for 12-24 hours. data-i="120">instant coffee is not suitable. freshly ground Instant coffee will not work.
- 🧂 Baking sodaA universal remedy for general disinfection. Dissolve 2 tbsp. l. soda in 1 liter of warm water and wipe all surfaces. To enhance the effect, leave an open pack of soda on the shelf for 1-2 days.
- 🍎 Apple cider vinegar. Effective against the smell of mold and mustinessMix vinegar with water in a 1:1 ratio, wipe the walls, then rinse with clean water. Do not use table vinegar -it is too aggressive for plastic.
- 🌿 Activated charcoal. Absorbs chemical and gaseous odors (for example, after defrosting or repair). Crush 10-15 tablets, scatter on a plate and leave for a day.
⚠️ Attention: Do not mix products! For example, soda and vinegar react, forming foam, which can damage plastic parts. Also avoid essential oils (lavender, tea tree) - they leave greasy marks and can be absorbed into. seals.
| Product | Efficacy | Action time | Suitable for |
|---|---|---|---|
| Lemon | ⭐⭐⭐ | 3–4 hours | Light food odors |
| Coffee | ⭐⭐⭐⭐ | 12–24 hours | Persistent aromas (smoked meats, spices) |
| Soda | ⭐⭐⭐⭐⭐ | 1–2 days | General disinfection, mold |
| Vinegar | ⭐⭐⭐ | 1 hour | Mustiness, mold |
| Coal | ⭐⭐⭐⭐ | 24 hours | Chemical odors |
Professional odor absorbers: what to choose
If traditional methods do not help or the smell returns too quickly, you should use it attention to specialized absorbers. They are divided into three types:
- Carbon filters. For example, Filtero FR-H10 or Zepter BioFresh. Absorb odors at the molecular level, suitable for refrigerators with
No Frost. Service life - 3–6 months. - Ionizers. Devices like Soehnle Fresh & Clean generate negatively charged ions that bind odor particles. They are effective against bacteria and mold, but require a connection to the network.
- Gel absorbers. For example, Air Wick Freshmatic or Ambi Pur. They last 4–8 weeks, but can leave their own aroma (lavender, citrus), which not everyone likes.
When choosing, pay attention to:
- 🔄 Term actions (from 1 month to a year).
- 🔌 Power type (from mains, batteries or without connection).
- 📏 Refrigerator size. For models with a volume of >300 liters (for example Samsung RL60T6L4177), an absorber with an increased coverage area is needed.
⚠️ Attention: Some absorbers (especially gel ones) may interact with plasticcausing cloudiness or stickiness. Before use, check the compatibility with your refrigerator model in the instructions.
How to check the authenticity of a carbon filter?
Original filters (for example, for Liebherr) have a holographic sticker and serial number. Counterfeits are often sold without packaging or with blurred markings. Before purchasing, check the article number with the official website of the manufacturer.
How to clean the drainage hole: step-by-step instructions
If there is a smell putrid or mustyand water accumulates at the bottom of the refrigerator, the problem is in the drainage system. In models with No Frost (for example, Indesit ITF 118) the drainage hole is located on the back wall, in drip models (ATLANT MXM 1835-100) - under the bottom shelf.
For cleaning you will need:
- 🧻 Cotton swabs or thin wire.
- 💦 A syringe or syringe with warm water.
- 🧼 Dishwashing liquid or soda.
Step-by-step algorithm:
- Turn off the refrigerator and remove all food.
- Locate the drainage hole (usually in the center of the back wall or under the vegetable drawer).
- Insert a cotton swab, soaked in soapy water and gently scroll. If the blockage is deep, use a wire (not metal!).
- Rinse the hole with warm water from a syringe. Water should flow freely into the tray.
- Wipe dry and leave the refrigerator open for 1 hour to dry.
If after cleaning water continues to accumulate, it may be clogged drainage hose (it goes from the hole to the compressor). In this case, it is better to call a specialist - cleaning the hose yourself can lead to damage to the system.
How to clean a refrigerator: safe detergents
Not all detergents are suitable for refrigerators. Aggressive chemistry (such as Domestos or Whiteness) can:
- 🔥 Damage the plastic (there will be microcracks).
- 🤧 Cause allergies upon contact with products.
- 💨 Leave your own chemical smell.
Safe alternatives:

| Topperr 3101 (spray) | Spray, after 5 minutes wipe with a dry cloth. | Acts quickly, does not require rinsing. | Contains fragrances. |
For stubborn contaminants (for example, yellowness on plastic) you can use paste of soda and hydrogen peroxide (1:1). Apply for 10 minutes, then rinse. Do not use on chrome plated or metal parts!
How to prevent odor from appearing: 7 rules of prevention
The best way to deal with odor is to prevent its occurrence. Enough seguir these simple rules:
- 📅 Regular cleaning. Wash the refrigerator every 1-2 months (more often if you have pets or people with allergies). Use a soft sponge and warm water.
- 🥩 Proper food storage. Keep meat and fish in vacuum bags or containers with a lid. Fruits and vegetables - in special boxes (do not mix apples and carrots - they spoil faster together!).
- 🧊 Humidity controlIn models without
No Frostregularly wipe condensation from the walls. Use desiccant (for example, Silica Gel). - 🔍 Checking the seals. Inspect the rubber gaskets on the door every six months. If they are cracked or deformed, replace them (the cost of a new seal for ATLANT —from 800 ₽).
- 🍞 Use odor absorbers. Even if there is no smell, keep a pack of soda or a charcoal filter in the refrigerator.
- 🌡️ Watch the temperature. Optimal mode:
+2…+5°Cin the main chamber and-18°Cin the freezer. At higher values, food spoils faster. - 🚫 Do not store in the refrigerator:
- Onions and garlic (they absorb moisture and spread the smell).
- Bread (stales faster).
- Bananas and tomatoes (they emit ethylene, which accelerates the spoilage of other products).
⚠️ Attention: If the refrigerator is equipped freshness zone (for example, BioFresh in Liebherr or FreshZone in Samsung), pay special attention to it. In such compartments the humidity is higher, so they need to be washed. every 2 weeks.
When it's time to call a specialist: signs of serious problems
If you have tried all the methods, but the smell comes back or is accompanied by other symptoms, the problem may be technical. Contact the service center if:
- 🔥 Smell burning or plastic is a sign of compressor overheating or insulation melting. Particularly dangerous for refrigerators with inverter compressor (For example, LG GA-B489YGGL).
- ❄️ On the back wall ice is forming (in models with
No Frost) - perhaps the evaporator heater or defrost sensor is broken. - 💧 Under the refrigerator a constant puddle of water —a clogged drain hose or a crack in the cooling system.
- 🔊 Refrigerator humming or clicking louder than usual - there may be a freon leak or a fan failure.
- 🦠 Smell ammonia or chemicals - a sign of a leak refrigerant (freon). Dangerous to health!
The average cost of diagnostics in service centers is from 1,500 rubles. Repairs (for example, replacing a compressor or drain hose) will cost 3,000–10,000 rubles, depending on model.
💡 Advice: Before the technician’s visit, take a photo or write down refrigerator model (located on the sticker inside the chamber or on the back wall) and describe the symptoms in as much detail as possible. This will speed up the diagnosis.
FAQ: Frequently asked questions about the smell in the refrigerator
Is it possible to use fragrances (air fresheners) for the refrigerator?
It is possible, but with caution. Gel fresheners (like Air Wick) can leave sticky traces, and sprays can permeate products with their aroma. It is better to choose neutral absorbers (soda, charcoal) or specialized products for refrigerators (for example, Sano Fridge Fresh).
Why does the smell come back a day after cleaning?
Most likely you missed it hidden source:
- Mold under the rubber seals.
- Clog in the drainage hose (water stagnates and rots).
- Expired product in the far corner.
Check these places and repeat cleaning using an antibacterial agent (for example, a solution of vinegar or Topperr 3101).
How to remove the smell of fish if it is absorbed into plastic?
Fish smell is especially persistent due to trimethylamine a substance that penetrates the pores of plastic. To eliminate it:
- Wash the refrigerator with a solution of vinegar (1:1 with water).
- Wipe the plastic surfaces lemon juice (acid neutralizes amines).
- Put on a shelf activated coal or coffee grounds for 24 hours.
- If the smell remains, buy absorber with silver ions (for example, Soehnle Fresh & Clean).
Is it possible to wash the refrigerator steam generator?
It is possible, but only if it is allowed in the instructions for the refrigerator. Steam kills bacteria well, but it can:
- Damage electronic displays (in models type Samsung Family Hub).
- Deform plastic shelves at high temperatures.
- Leave condensation in hard-to-reach places, which will lead to mold.
If you decide to use a steam generator, keep the nozzle at a distance 20–30 cm from the surface and do not direct the stream at the seals.
What is the danger of the smell of freon in the refrigerator?
Freon (refrigerant) in modern refrigerators (R134a, R600a) non-toxic, but its leakage leads to:
- Loss of cooling capacity (the refrigerator stops freezing).
- Increased load on the compressor (risk of burnout).
- The appearance of oil stains on the floor (freon circulates along with the oil).
If you smell sweetish chemical smell immediately turn off the refrigerator and call a technician. Self-repair prohibited (freon is under pressure!).
