How to clean the refrigerator from odors: a complete guide with photos and expert advice

Even the most modern refrigerator can begin to smell unpleasant over time. The reasons are varied: from spilled milk to food spoilage in the far corner. But regardless of the source, eliminate the smell from the refrigerator you can do it yourself - without calling a specialist and without expensive means. The main thing is to act systematically: first remove the source, then carry out deep cleaning, and finally, prevent the reappearance of odors.

In this article you will find step-by-step instructions for different types of odors (rotten, fishy, chemical, mold), a list of proven remedies - from those at hand (soda, vinegar, coffee) to professional (OdorGone, Smeg), as well as compatibility table refrigerator materials with cleaning compounds. A special section is dedicated to know-how 2026 - the use of UV lamps for disinfection chamberswhich removes odors at the molecular level.

Important: if the smell appears after a power outage or defrosting, first check whether this is due to technical malfunction (for example, a freon leak). In such cases, cleaning will not help - diagnostics of the compressor or seal is required.

1. Preparation: what to do BEFORE cleaning the refrigerator

Start with complete release of the chambers. Remove all food, shelves, containers and drawers. Check expiration dates - often the source of the smell lies in expired yogurt on the door or a forgotten jar of sauce. Pay special attention to:

• 🧀 Dairy products —cottage cheese, sour cream, cheeses “hide” the smell of rot under the crust.
• 🥩 Meat and fish —even in vacuum packaging, decomposition processes can begin.
• 🍎 Fruits/vegetables in boxes - rotten apples or onions emit ethylene, which accelerates the spoilage of other products.
• 🧴 Open sauces and marinades - vinegar and spices mask the rotten smell.

Unplug the refrigerator and let it 1–2 hours stand with the door open - this will reduce the concentration of odor. If the model has a system No Frost, it is enough 30–40 minutes. To speed up the process, you can use a fan directed into the chamber.

⚠️ Attention: Do not use to clean the refrigerator chlorine-containing products (type White) - they react with plastic and metal, forming toxic compounds. Also avoid abrasive powders: they scratch the surface, and bacteria accumulate in microcrackslater.

2. Folk remedies: what is in the kitchen to combat odor

Home remedies not only save the budget, but are also safe for health. Their main advantage is that it can be absorbed into products. Let's consider the top 5 options: no chemical aftertaste, which can be absorbed into food. Let's look at the top 5 options:

For persistent odors (for example, after defrosting with rotten products) combine remedies. For example:

1. Rinse the refrigerator soda solution.
2. Wipe the seal and corners vinegar.
3. Place on the shelf coffee or charcoal for 12 hours.

3. Professional remedies: when traditional methods do not help

If the smell lasts for more than a week or persists chemical nature (for example, after washing with aggressive detergents), it’s time to move on to specialized formulations. They are divided into 3 types:

• 🧪 Enzyme cleaners (for example, OdorGone, Bio-Mist) - break down organic odor molecules.
• 🔬 Ionizers (sprays AirComfort, X-Mist) - neutralize odors due to positive ions.
• 🦠 Antibacterial (Smeg Cleaner, Dr. Beckmann) - kill bacteria that cause a putrid odor.

For models with antibacterial coating (for example, LG DoorCooling+ or Samsung Twin Cooling) are only suitable acid-free products marked "for stainless steel". Use them according to the instructions:

1. Spray at a distance of 20 cm from the surface.
2. Leave for 5-7 minutes (do not let it dry!).
3. Wipe with a microfiber cloth.
4. Repeat if necessary after 24 hours.

For plastic odor (typical for new refrigerators) use car interior polish (for example, Sonax Plastic Cleaner). Apply to cotton wool, wipe the inner walls and seal - this will remove the “chemical” odor in 1 application.

4. Cleaning hard-to-reach places: seals, drainage, ventilation

Even thorough washing of the chambers does not guarantee complete removal of the odor, unless treated hidden areas:

Sealing rubber accumulate dirt and mold. To clean it:

1. Moisten a toothbrush in a soda solution (1 tablespoon per glass of water).
2. Gently wipe all folds of the seal.
3. Use for disinfection hydrogen peroxide 3% (do not dilute!).
4. Lubricate the rubber silicone grease (sold in car dealerships) to prevent cracking.

Drain hole (located on the back wall of the refrigerator) is often clogged with food particles, which leads to stagnation of water and a putrid odor. Cleaning: Drainage hole data-i="186">Gently push into the hole, then rinse

• 🔧 Take it plastic straw (from a cocktail) or knitting needle.
• Gently push into the hole, then rinse with warm water and vinegar (1:1).
• For prevention, drip into the drain 1-2 drops of tea oil wood once a month - it prevents the growth of bacteria.

Ventilation grilles (in models No Frost) are cleaned with a vacuum cleaner with a narrow attachment. First remove the grille (if provided for by the design) and soak in a soapy solution for 30 minutes.

⚠️ Attention: Never use for cleaning drainage metal objects (wire, knife) - they can damage the plastic tube, which will lead to freon leakage. If the blockage is severe, it is better to call a technician.

5. UV lamps and ozonizers: high-tech methods

The use of UV lamps for disinfection of the refrigerator is a trend in 2026. Ultraviolet light destroys the DNA of bacteria and viruses, eliminating odor at the molecular level. Suitable devices:

• 💡 Philips UV-C TUV PL-L 11W - compact lamp, 15 minutes of exposure is enough.
• 🔦 Xiaomi Mi Portable UV Sterilizer —a portable sterilizer with a timer.
• 🧬 Ozone Generator 5000mg/h —an ozonizer that kills odors in 10 minutes (but requires ventilation after use!).

Instructions for using a UV lamp:

1. Turn off the refrigerator, remove all food.
2. Place the lamp in the center of the chamber for 10–20 minutes (the exact time is indicated in the instructions for the model).
3. After treatment, wipe the surfaces with a damp cloth - dead bacteria may remain in the form of a film.
4. Ventilate the refrigerator 1–2 hours before loading food.

Ozonizers are more aggressive: they not only kill bacteria, but also destroy odor molecules. However, after using them, the refrigerator cannot be opened at least 30 minutes - ozone is toxic to humans. It is better to carry out the treatment on a balcony or in a well-ventilated area.

Can UV lamps be used for refrigerators with an ice maker?

Yes, but with reservations:

1. First remove the ice from the generator and rinse it with water.

2. Direct the lamp away from plastic parts —UV rays can make them brittle

3. After treatment, run the ice cycle 2-3 times to wash away any remaining ozone or bacteria.

6. Prevention: how to prevent odor

Regular care reduces the risk of odor by 90%. Basic rules:

Weekly:

• 🧼 Wipe the shelves and door with a damp cloth with soapy water.
• 🗑️ Check the expiration dates of products (especially in the "zone freshness").
• 🍋 Place on the shelf a slice of lemon or a bag of vanilla sugar —they neutralize light aromas.

Once a month:

• 🧊 Defrost the refrigerator (even if it No Frost —ice may form in hidden places).
• 🧽 Wash containers for vegetables/fruits in soda solution (1 tbsp per 1 liter of water).
• 🔍 Check the drainage hole for blockages.

Once every 3 months:

• 🧴 Apply to the seal silicone grease (prevents cracking).
• 🔋 Clean the ventilation grilles (in models with No Frost).
• 🛡️ Treat the internal surfaces antibacterial spray (for example, Smeg).

For long-term protection use odor absorbers:

• 🧂 Salt tablets (for example, Fridge Fresh) - lasts up to 3 months.
• 🍃 Bamboo charcoal - environmentally friendly, lasts up to 2 years (needs to be “regenerated” in the sun once a month).
• 🧪 Gel absorbers (Air Wick, Ambi Pur) - masks odors aromas.

7. Features of cleaning refrigerators of different brands

The design and materials of refrigerators vary depending on the manufacturer. This influences the choice of cleaning products and methods:

For refrigerators with water dispenser (for example, Samsung RS6HA), additionally clean the water supply pipes every 6 months. Use special tablets for cleaning coffee machines (for example, Durgol):

1. Dissolve 1 tablet in 1 liter of water.
2. Pour the solution through the dispenser.
3. water (3-4 cycles).

⚠️ Attention: In refrigerators with electronic control (for example, LG ThinQ), you cannot use wet cloths to clean the panel - this can cause a short circuit. Use dry microfiber wipes alcohol-based sprays.

8. When cleaning does not help: possible malfunctions

If the smell does not disappear after deep cleaningthe problem may lie in technical malfunction. Common reasons:

1. Freon leakage

• 🔧 Signs: The refrigerator does not freeze well; rust appears on the back wall, the smell resembles acetone or a sweetish chemical odor.
• 🛠️ Solution: Immediately turn off the refrigerator and call a technician!

2. Capillary tube clogged

• 🔧 Signs: The compressor runs without stopping, the chamber is warmer than usual, smell burnt oil.
• 🛠️ Solution: The system needs to be flushed or replaced tubes.

3. Malfunction of the seal

• 🔧 Symptoms: You can see it on the door condensation, the smell is felt even when the refrigerator is closed, the seal has lost its elasticity.
• 🛠️ Solution: Replacement of sealing rubber (cost - from 1500 to 3000 rubles depending on the model).

4. Mold in the evaporator (typical for models with drip system)

• 🔧 Signs: Smell dampness and rot, black dots on the back wall.
• 🛠️ Solution: Defrosting + evaporator treatment hydrogen peroxide 3% or special antifungal spray.

If the refrigerator newbut smells of plastic or chemicals, this is normal for the first 1–2 weeks operation. The following will help speed up weathering:

• 🍋 Wiping the walls lemon solution acid (1 tsp per 1 liter of water).
• ☀️ Ventilation with the door open during the day.
• 🧊 Loading products only after the smell disappears.

FAQ: Frequently asked questions about odors in the refrigerator

❓ Why does the refrigerator smell after defrosting? rotten meat?

This is due to decomposition of organic residues in the drainage system. During defrosting, water with food particles flows into the pan, where putrefactive processes begin. Solution:

1. Rinse the drainage hole soda solution.
2. Dry the tray (it is usually located at the back of the refrigerator).
3. Treat system hydrogen peroxide.

❓ Is it possible to use refrigerator flavors?

Yes, but with caution. Natural flavors (lemon, coffee, vanilla) are safe. But synthetic fresheners (for example, Air Wick) can:

• Mask the smell of rot rather than eliminate it.
• React with plastic (especially in models Indesit and Atlant).
• Give products a chemical taste.

It is better to use odor absorbers (charcoal, salt), rather than masking agents.

❓ How to remove the smell of fish from the refrigerator?

Fishy smell is one of the most persistent. Algorithm of actions:

1. Rinse all surfaces with a 1:1 vinegar solution.
2. Wipe seal a mixture of soda and peroxide (1:1).
3. Place in the refrigerator orange or grapefruit peel for 12 hours.
4. If the smell remains, use ozonator (for example, Ozone Generator 5000mg/h).

Important: do not store fish in the refrigerator for longer 1-2 days (even in vacuum packaging).

❓ Why does a new refrigerator smell like plastic?

This is normal for the first ones 1-3 weeks - this is how they erode process oils and plasticizersTo speed up the process:

• Wipe the internal surfaces citric acid solution (1 tsp per 1 liter of water).
• Place inside a bag of activated carbon.
• Do not load food until the smell disappears.

If the “chemical” smell lasts longer than a month, this is a reason to contact the service center (the plastic may be defective).

❓ How often should you wash the refrigerator so that it does not odor?

The optimal frequency of cleaning depends on the intensity of use:

• Families with children - once every 1–2 weeks (wipe shelves weekly, once every 2 weeks - general cleaning).
• Lonely people —once every 3–4 weeks.
• Refrigerators with No Frost —once every 2 months (but check the drainage monthly!).
• Freezers - once every 6 months (if there is no ice).

Additional:

• After large purchases (for example, bulk purchases of meat/fish), wash the refrigerator within 24 hours.
• If you stored products with a strong odor (garlic, spices), ventilate the chamber 1–2 hours s open door.
