An unpleasant smell in the refrigerator is a problem that every home cook faces. Even with regular cleaning, the aroma of sour milk, rotten meat or mustiness may suddenly appear. The reasons are varied: from spoiled food to bacterial plaque on the seal. The main thing is not to mask the smell, but eliminate its source and prevent its reappearance.
In this article we have collected 15 effective methodshow to get rid of the smell in the refrigerator quickly - from improvised means (soda, vinegar, coffee) to professional absorbers. Let's consider methods for different situations: fresh smell, old "aroma", mold and specific cases (for example, after defrosting or a power outage). All recommendations have been tested in practice and are safe for equipment Samsung, LG, Indesit and other popular brands.
We will pay special attention three critical mistakesthat 90% of users use when dealing with odors: ignoring the drainage hole, improperly washing the rubber seal and the use of harsh chemicals. These nuances can not only return the smell in a week, but also damage the refrigerator.
Why an unpleasant odor appears in the refrigerator: 7 main reasons
Before looking, how to remove the smell from the refrigeratorit is important to understand its source. In 80% of cases, the problem lies not in the products themselves, but in the microclimate of the chamber. Here are the key reasons:
- 🥛 Spoiled food - even a small piece of moldy cheese or sour milk can “aromatize” the entire refrigerator in a day.
- 🦠 Bacteria and fungus - multiply on the walls, shelves and seal, especially if temperature above +5°C.
- 💧 Clogged drainage hole —leads to stagnation of water and a putrid odor (relevant for models with a system No Frost and drip defrosting).
- 🧽 Improper cleaning — use of detergents with fragrances or insufficient drying after washing.
- 🔌 Power outage —if the refrigerator has been left turned off for more than 4 hours, food begins to deteriorate even in a closed chamber.
- 🧊 Ice and condensation — ice with odors accumulates in the freezer, which, when defrosted, spreads throughout the entire volume.
- 📦 New plastic containers - can emit a chemical odor for the first 1-2 weeks (especially cheap models from polystyrene).
Interesting fact: in refrigerators with a system Total No Frost (for example, Bosch Serie 8 or Liebherr Premium) odors spread faster due to active air circulation. At the same time, models with a freshness zone (Fresh Zone) maintain a neutral microclimate longer.
⚠️ Attention: If the smell appeared after purchasing a new refrigerator, do not rush to use absorbers. In the first 3-5 days, the “factory” aroma of plastic and compressor grease may be felt. It is enough to ventilate the chamber with the door open for 12-24 hours. data-i="82">Attention:
How to remove the smell from the refrigerator in 1 hour: express methods
If the smell is fresh (appeared less than 2 days ago), it can be eliminated quickly and without defrosting. Here 5 waysthat work in 95% of cases:

How to get rid of old odors: deep cleaning
If the smell lasts in the refrigerator for more than a week, conventional methods may not work. Here you need complex processing, including defrosting, disinfection and eliminating the source. Follow the algorithm:
- Defrosting. products. In models with No Frost 2-3 hours are enough, in drip models - 6-8 hours.
- Washing with disinfection. Use specialized products:
- 🧴 Sanita Gel for refrigerators (destroys 99.9% bacteria).
- 🧽 Topperr 3101 - professional cleaner for equipment.
- 💊 Chlorhexidine 0.05% - pharmaceutical antiseptic (dilute 1:1 with water).
- 🍋 Citrus zest (orange, grapefruit) - keep for 3-5 days.
- 🧂 Salt in bags - change once a week.
- 🌿 Essential oils (tea tree, lavender) - 2-3 drops on a cotton pad.
For models with a system Twin Cooling (for example, Samsung RB37J5230SA), be sure to clean second evaporator in the freezer compartment - ice with absorbed odors often accumulates there. Access to it is usually opened after removing the back panel of the freezer (see instructions). to your model).
⚠️ Attention: Never use bleach, acetone or abrasive powdersto clean the refrigerator. They damage the plastic and leave toxic fumes that are absorbed into the food. For stubborn mold stains, use only baking soda or hydrogen peroxide 3%.
What to do if the smell returns after a week?
If after deep cleaning the smell appears again, the problem lies in hidden sources:
1. Check ventilation grilles (in models with No Frost) - dirt may accumulate there.
2. Inspect compressor compartment (bottom back) - sometimes crumbs or liquid get there and rot.
3. Replace charcoal filter (if your model has it, for example, in Liebherr ICBN 3366).
4. Check door tightness - if the seal is worn out, warm air penetrates inside, accelerating food spoilage.

- 🍄 Mold/mustiness:
Treat the walls and seal hydrogen peroxide 3% or chlorhexidine. hairdryer (cold air!) for 10–15 minutes.
- 🥩 Smell of meat/sausage:
Place on shelves apple pieces —they absorb animal fats and aromas. Change every 4-6 hours.
For refrigerators with a function Air Flow (for example, LG Instaview Door-in-Door) after processing, turn on the mode Odor Filter (if any) - it will increase air circulation through the filter.
Prevention: how to prevent the occurrence. odor
The best way to combat odors is prevent their occurrence. Follow these rules:
- Product control:
- 📅 Inspect once a week - throw away expired.
- 🥫 Store opened canned food in airtight containers.
- 🍖 Place meat and fish on the bottom shelf (the coldest place).
- Space organization:
- 🧊 Use vacuum containers for cheeses, sausages, herbs.
- 🍎 Store fruits and vegetables in special boxes with controlled humidity.
- 🥛 Keep dairy products in closed packages on medium shelf.
- Care of equipment:
- 🧽 Once a month, wash the refrigerator with a soda solution.

- 🔄 Defrost the freezer when layered ice more than 5 mm.
- ☕ Keep on the door an open pack of soda in a fabric bag.
- 🌿 Once every For 2 weeks, place coffee beans or citrus zest.
- Defrosting. Unplug the refrigerator and leave the door open. In models with No Frost ice melts in 2-3 hours, in regular models - up to 12 hours.
- Removing ice. Do not scrape with a knife - use plastic scraper or warm water in a spray bottle.
- Washing. Wipe the walls with a solution ammonia alcohol. After washing, place: air). (1 tbsp per 1 liter of water) - it removes even old odors.
- Absorbers. After washing, place:
- ❄️ Silica gel sachets (absorb moisture and odors).
- 🧊 Ice cubes with lemon juice (refreshes the air).
- Drying. Before turning on, dry the chamber with a towel and ventilate for 1-2 hours.
In refrigerators with freshness zone (for example, Samsung Family Hub or Bosch VitaFresh) maintain the temperature 0°C–+1°C - this slows down the growth of bacteria and prolongs the freshness of products.
⚠️ Attention: If your refrigerator has a function Antibacteria (for example, in models Sharp or Hitachi), do not turn it off - it suppresses the growth of bacteria by 90%. Also, avoid placing perishable foods on the top shelf (the warmest).
What to do if there is a smell in the freezer
The freezer requires a separate approach. Here, odors are “absorbed” into the ice and can persist for years. Cleaning algorithm: Turn off the refrigerator, leave the door open. models with
For freezers with a system Frost Free (for example, Electrolux ENF3854AOX) after defrosting, turn on the mode Fast Freeze for 24 hours - this will help “seal” possible residual odors under a layer of new ice.
FAQ: Frequently asked questions about odors in the refrigerator
Is it possible to use an air freshener for refrigerator?
No, this is a temporary solution. Fresheners (for example, Air Wick or Glade) only mask the smell, but do not eliminate its cause. Moreover, their aromas can be absorbed into foods. Use only absorbers (charcoal, soda, coffee) that neutralize odor molecules.
Why does the smell return after a few days after washing?
Most likely, you missed it hidden source:
- Mold under the rubber seal.
- Dirt in the drainage hole.
- Spoiled product in the far corner (for example, sauce under the egg tray).
- Dirty fan in models with No Frost.
Check these areas and repeat cleaning.
How to remove the smell of plastic in a new refrigerator?
This is normal for the first days of operation. To speed up weathering:
- Rinse the chamber with a soda solution (2 tablespoons per 1 liter of water).
- Wipe the walls vegetable oil (with a thin layer on a napkin) - it will bind chemical vapors.
- Ventilate the refrigerator with the door open for 24–48 hours.
- Place inside bags with activated carbon or orange peels.
Avoid aggressive detergents - they can react with plastic and increase the smell.
Does an ozonizer for a refrigerator help?
Yes, but with reservations. Ozonizers (for example, Timberk TOS-O05) destroy bacteria and decompose odor molecules, but:
- They cannot be used when there is food in the refrigerator (ozone is toxic).
- After treatment, the chamber must be ventilated for 1-2 hours.
- Not suitable for models with air ionizer (may fail).
Optimal use: 1 time every 3 months for deep disinfection.
How to wash the inside of the refrigerator so that there is no smell?
Safe and effective products:
- Food soda (2-4 tbsp per 1 liter of water) - removes fat and neutralizes odors.
- Vinegar 9% (1:1 with water) - disinfects, but can leave its own aroma (ventilate after use).
- Laundry soap (only natural, no fragrances) - suitable for plastic and glass.
- Hydrogen peroxide 3% - kills mold and bacteria (do not dilute!).
- Special products: Topperr 3101, Sanita Gel, Ecover (eco-option).
