Unpleasant smell in the refrigerator - a problem that every home cook faces. Even with regular cleaning, persistent odors from fish, cheese or spoiled food can penetrate plastic, rubber seals and be absorbed into surfaces. Eliminate the smell once and for all This is only possible with an integrated approach: proper washing, disinfection and prevention.
In this article you you will find proven methodshow to clean the refrigerator from odors at home - from available folk remedies (soda, vinegar, coffee) to professional chemicals. We will analyze step-by-step cleaning technology for refrigerators with the No Frost system and drip defrostingand also tell you how to prevent the appearance of unpleasant odors in the future. All methods are safe for equipment and do not require special skills.
Why there is a smell in the refrigerator: 5 main reasons
Before you start cleaning, it is important to understand the source problems. Most often, an unpleasant odor occurs due to:
- 🍎 Spoiled products - even a small piece of moldy cheese or sour milk can become a source of persistent ammonia or sour aroma.
- 🧊 Improper defrosting - in models with a drip system (Indesit, Atlant, Turk) with infrequent cleaning, dirt and bacteria accumulate in the drainage hole.
- 🧽 Dirty seals —rubber gaskets on the door absorb odors and require separate processing.
- 🦠 Mold and mildew —appear in refrigerators with high humidity (especially in the area for vegetables).
- 🔌 Ventilation system malfunctions —in models No Frost (Samsung, LG, Bosch) when the fan breaks down, odors stagnate.
If the smell appears suddenly, first check temperature mode - if the thermostat breaks down, the food may thaw and spoil faster. In refrigerators with electronically controlled (Liebert, Electrolux), the error can be seen on the display (codes E1, F2 etc.).
⚠️ Attention: If there is a smell accompanied ice flakes on the back wall (in models without No Frost), this is a sign of a clogged drainage system. You need to rinse it with a special brush or tube so as not to damage the capillaries.
Preparing the refrigerator for cleaning: 7 mandatory steps
To effectively wash the refrigerator from odors, it must be properly prepared. Follow this algorithm:
- Turn off the power - remove the plug from the socket or turn off the machine on the panel (if the refrigerator is connected directly).
- Take out all products - put them in a cooler bag or a bowl of ice. Do not leave perishable foods out of the refrigerator for more than 2 hours.
- Remove all removable elements —shelves, drawers, wire racks, egg trays. They need to be washed separately.
- Take out the drain pan (if any) - usually it is located at the back or under the freezer.
- Wipe off the condensation - remove moisture from the inner walls with a dry cloth or paper towels.
- Check the seals - if the rubber is cracked or deformed, it will have to be replaced (spare seals are sold for most models Samsung, Indesit, Atlant).
- Prepare tools - you will need: sponges, soft rags, toothbrush (for hard-to-reach places), spray bottle, rubber gloves.
For models with No Frost (Bosch, LG, Samsung, be sure to wait for complete thawing - this usually takes 4-6 hours. In refrigerators with a drip system (Atlant, Biryusa), 1-2 hours are enough.

How to clean the refrigerator from odor: top 10 products
The choice of product depends from odor intensity and the material of the internal surfaces. For plastic, gentle compositions are suitable, but for persistent aromas (fish, garlic, rotten eggs) more aggressive solutions will be needed.
| Remedies | For what odors | How to use | Pros | Cons |
|---|---|---|---|---|
| Baking soda | Weak odors, prevention | 2 tbsp. l. for 1 liter of water, wipe the surfaces | Safe, cheap, removes grease | Cannot cope with persistent aromas |
| Vinegar 9% | Sour smell, mold | 1:1 with water, spray, rinse after 10 minutes | Disinfects, kills bacteria | Pungent odor, can damage rubber |
| Lemon juice | Fish, onion smell | Juice of 1 lemon per 0.5 liter of water | Refreshes, removes fat | May leave stains on stainless steel |
| Ammonia | Ammonia smell, animal urine | 1 tsp. per 1 liter of water, wipe, ventilate | Effective against persistent odors | Toxic, requires ventilation |
| Activated carbon | Absorption of odors after cleaning | Place the tablets in bowls on the shelves | Natural absorbent | Acts slowly (needs 2-3 days) |
For refrigerators with ionic silver (Panasonic, Hitachi) it is not recommended to use chlorine-containing products - they can cause damage antibacterial coating. In such models, it is better to use specialized compounds, for example Topperr 3101 or Clean Home for refrigerators.

Step-by-step instructions: how to clean the refrigerator from odor
Carry out cleaning in well-ventilated area, especially if you use ammonia or vinegar. Follow this algorithm:
1. Washing removable elements
Soak shelves, drawers and trays in warm water with the addition of dishwashing detergent (for example, Fairy or Sorti) for 15–20 minutes. For stubborn stains, use melamine sponge, but without strong friction - it can scratch the plastic. After washing, rinse the elements under running water and wipe dry.
2. Cleaning internal surfaces
Apply the selected product (for example, a solution of soda or vinegar) to the walls of the refrigerator using a sponge or spray bottle. Pay special attention to:
- 🔍 Sealing rubber —wash it with a toothbrush dipped in soapy water.
- 🕳️ Drainage hole —clean it with a cotton swab or a special brush (sold in hardware stores).
- 🥬 Boxes for vegetables —dirt and juice from food often accumulate there.
3. Disinfection
After washing, wipe all surfaces chlorhexidine solution (0.05%) or hydrogen peroxide (3%). These products kill bacteria and prevent mold. Do not use undiluted chlorhexidine - it can leave white streaks on the plastic.
4. Drying and airing
Leave the refrigerator open for 1-2 hours so that the moisture completely evaporates. To speed up the process, you can use a fan. Never turn on the refrigerator when wet - this will lead to a short circuit or corrosion of metal parts..
5. Installing an odor absorber
After cleaning, place on the shelves natural absorbents:
- ☕ Coffee beans - absorb odors and give a light aroma (change once every 2 weeks).
- 🍋 Citrus zest - freshens the air, but does not last long (3-5 days).
- 🧂 Salt in a bag - absorbs moisture and neutralizes odors (change once a month).
How to remove a persistent odor: emergency methods
If the smell remains after standard cleaning, try these enhanced methods:
1. Ozone treatment
Ozonizers (for example, AirComfort XJ-3000C) destroy odor molecules at the chemical level. Connect the device to the mains, place it inside the refrigerator for 15–20 minutes, then ventilate. The method is suitable for refrigerators with No Frostwhere odors are often retained in the ventilation system.
2. Steam cleaning
Use steam cleaner (for example, Karcher SC 2) with a nozzle for hard-to-reach places. Steam kills up to 99% of bacteria and removes odors from microcracks in plastic. The steam temperature should not be higher 100°Cso as not to deform the seals.
3. Ultraviolet lamp
UV lamp (for example, Philips TUV 15W) destroys mold and bacteria - the main sources of unpleasant odors. Place the lamp inside the refrigerator for 10–15 minutes, then wipe the surfaces with a dry cloth. Do not look at the working lamp - this is dangerous for your eyesight!
⚠️ Attention: If the smell appears after defrosting a refrigerator with a No Frost system, check evaporator for ice. Its formation may indicate malfunction of the defrosting heating element or a sensor. In this case, repairs will be required.

| LG (with silver ions) | Does not tolerate acidic and alkaline agents - they destroy the antibacterial coating. | Vinegar, ammonia, bleach | LG Cleaning Kit, soap solution |
| Indesit, Biryusa | Sealants quickly wear out - clean only with soft agents. | Hard brushes, powders | Sanita Antibacterial, soda |
For refrigerators with a water dispenser (Samsung RS62R5001, LG GC-B247SLUV) be sure to rinse the tubes and container for water with a solution of soda (1 tablespoon per 1 liter of water) once every 3 months. Otherwise, there may appear black mold.
How to clean the drainage hole in Atlant and Biryusa refrigerators?
In these models, the hole is often clogged with crumbs and dirt. Take a syringe or syringe without a needle, fill it with warm water and soda (1 teaspoon per glass) and rinse the hole under pressure. If the water does not go away, use a wire with a diameter of 2–3 mm, but act carefully so as not to damage the tube.
Odor prevention: 7 rules for freshness
To prevent the smell from returning, follow these recommendations:
- Check the products once a week —throw away everything with an expired expiration date, even if the product looks normal in appearance.
- Use containers with lids - especially for fish, cheese, onions and garlic. Glass or plastic boxes are suitable (Tupperware, Lock&Lock).
- Wash the seals regularly —wipe them with a damp cloth and soap every 2 weeks.
- Defrost every 3-6 months —even in models No Frost condensation accumulates.
- Ventilate the refrigerator - once a month, leave it open for 10-15 minutes (after turning it off).
- Use odor absorbers —for example, charcoal filters or gel fresheners (Air Wick, Glade).
- Watch the temperature —in the main chamber should be
+2…+5°C, in the freezer --18°C. At higher values, food spoils faster.
If there is freshness zone in your refrigerator (for example, BioFresh in Liebert or FreshZone in Bosch, wash it separately once every 2 weeks with a vinegar solution (1 tablespoon per 1 liter of water). In this zone, the humidity is high, which promotes the growth of bacteria.
