How to get rid of the smell in the refrigerator and freezer: proven methods and life hacks

An unpleasant smell in the refrigerator is a problem that almost everyone faces. He appears suddenly: either because of a fish forgotten on the back shelf, or after a power outage, or simply “on his own.” But if you can still quickly deal with aromas in the main chamber, then odor in the freezer often becomes a real test. Ice absorbs foreign molecules, and low temperatures preserve them for months.

In this article we will analyze all possible reasons the occurrence of odors - from bacterial decomposition to chemical reactions of plastic with products. We will give step-by-step instructions elimination methods, including emergency methods for strong “amber” and delicate methods for sensitive surfaces (for example No Frost). We’ll also tell you how to prevent the reappearance of the smell, using both improvised means and professional absorbers.

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

To effectively eliminate the smell, you need to understand it source. The most common culprits are:

• 🍳 Spoiled food - even a small piece of meat or sauce, “lost” behind a drawer, can become a breeding ground for bacteria.
• 🧊 Ice in the freezer - absorbs odors like a sponge, especially if you store fish, onions or spices there.
• 🦠 Mold and mildew —appear in the sealing gum, on the back wall or in the drainage hole.
• 🧴 Chemical reactions —new plastic containers or packaging may “smell” in the first weeks.
• 🔌 Power outage —even short-term leads to defrosting and spoilage of food.
• 🚰 Water stagnation —in the pan under the refrigerator or in the system No Frost liquid with organic residues accumulates.
• 🐭 Rodents or insects —rarely, but it happens that mice or ants die in the ventilation holes.

Particularly insidious odors in the freezer with the No Frost system —they circulate in a closed circuit and “eat” into the plastic. If the cause is not eliminated, even after cleaning, the aroma will return in 1-2 weeks.

Preparing the refrigerator for cleaning: what needs to be done BEFORE removing the smell

Before taking on soda solutions or vinegar prepare the refrigerator correctly:

1. Unplug - this is mandatory for safety and so that the ice in the freezer does not melt during cleaning.
2. Take out all the food - check the expiration dates, throw away anything suspicious. Place food from the freezer in a cooler bag or wrap it in newspaper.
3. Remove all removable elements —shelves, drawers, racks. They need to be washed separately.
4. Let the ice thaw —if there is ice in the freezer, do not try to scrape it off with a knife! Place a bowl of hot water inside and close the door for 20-30 minutes.

To speed up the process, you can use a hair dryer (at minimum power!) or special ice scraper (for example, from Bosch or Electrolux). But under no circumstances use metal objects - they will damage the coating.

⚠️ Attention: If your refrigerator has a system No Frost, do not use abrasive detergents - they will damage the antibacterial coating. Limit yourself to soft gels or specialized sprays (for example, Topperr 3104).

Top 5 folk remedies for odor removal: what really works

Do not rush to the store for expensive absorbers. Often improved means they cope with odors are no worse:

For freezers it is better to combine methods: first vinegar (for disinfection), then soda (to neutralize the odor. If the aroma persists, repeat the procedure after 12 hours.

Professional odor absorbers: when traditional methods do not help

If the smell is persistent (for example, from rotten meat or chemical leaks), folk remedies may not cope. In such cases, use:

• 🧪 Ozonizers — devices that destroy odor molecules (for example, AirComfort XJ-2100). Suitable for strong ambers, but require ventilation after use.
• 🧲 Ionizers - clean the air and kill bacteria (models Panasonic F-VXH50 or Xiaomi Mi Air Purifier).
• 🧂 Absorbers with zeolite - a mineral that absorbs odors at the molecular level (for example, Bork K704).
• 🧴 Special gels - for example, OdorGone or FreshBox. Valid for up to 3 months.

For refrigerators with No Frost it is better to choose absorbers without strong flavors - they can mix with the circulating air and give an unpleasant “cocktail.” The best option is carbon filters or UV lamps (built-in, for example, in models Samsung RB37J5240SA).

⚠️ Attention: If the smell appears after defrosting a refrigerator with freon, immediately ventilate the room and call a technician. This could be a refrigerant leak - it is dangerous to health!

How to remove the smell from the freezer: step-by-step instructions

The freezer is the most problematic place. Here, odors “eat into” the ice and plastic, and low temperatures preserve them. To get rid of the aroma:

1. Defrost the freezer completely —no “half-hearted” measures! Use warm water or a hairdryer (keep at a distance of 30 cm).
2. Remove all remaining ice - even small pieces can retain the smell.
3. Rinse the walls with the solution:
   • For greasy odors (fish, meat): vinegar + soda (1:1).
   • For chemical (plastic, paint): water + ammonia (1 tbsp. per 1 l).
   • For mold: chlorhexidine (0.05% solution).

Dry the freezer — leave the door open for 1-2 hours or use fan.

Treat with an absorber - put activated carbon or special gel for 12-24 hours.

If the smell remains, repeat the procedure, but at the washing stage add in water 1 tsp. hydrogen peroxide - it destroys organic molecules.

What to do if the freezer smells like “plastic”?

This smell often appears in new refrigerators (for example, Indesit ITS 5180 W or ATLANT MXM 2835-90). It is associated with the release of volatile compounds from the seal or inner coating. To eliminate:

1. Rinse the freezer with water and lemon juice (1:1).

2. Place a bowl of rice on the shelf - it will absorb chemical fumes.

3. Ventilate the refrigerator for 2-3 days with the door open.

If the smell does not go away after a week, contact a service center - the materials may be defective.

What NOT to do when removing odor: 5 dangerous mistakes

Some “tips” from the Internet can only aggravate the problem. Avoid:

• 🧴 Use of aggressive chemicals — Domestos, White or acetone destroys plastic and rubber seals. For disinfection, take only food grade products (for example, Sano Refrigerator Cleaner).
• ❄️ Scraping ice with a knife —scratches on the walls will become a breeding ground for bacteria. Use a plastic scraper or a wooden spatula.
• 🔥 Heating the freezer with hot water from a kettle —a sudden temperature change can damage the system No Frost.
• 🧼 Using scented detergents —they mask the smell, but do not remove its cause. After such “cleaning,” the aroma will return in a few days.
• 🚪 Closing the refrigerator immediately. after washing —moisture inside will lead to new mold. Dry for at least 1 hour!

Be especially careful with refrigerators with a display (for example, LG InstaView or Samsung Family Hub). When washing such models, unplug them and avoid direct contact with water on the panel.

Prevention of odors: how to maintain freshness for a long time

In order not to deal with odors every 2-3 months, follow simple rules:

• 📅 Defrost the freezer every 3 months - even if you have No Frost. Ice still forms, albeit in smaller quantities.
• 🧺 Use). covers for shelves - silicone or bamboo (for example, from IKEAThey are easier to clean and they protect the plastic.
• 🧂 Place an odor absorber - even an ordinary pack of soda on the middle shelf will reduce the risk of “amber” by 70%.
• 🍎 Store food correctly:
  • Meat and fish - in airtight containers containers (for example Tupperware or Lock&Lock).
  • Cheeses - in parchment paper, not in polyethylene.
  • Onions and garlic - in mesh bags, not in bags.
• 🧽 Wash the refrigerator once a month - even if there is no visible contamination. Use a soft sponge and a vinegar solution (1 tbsp per 1 liter of water).

If your refrigerator has a function Vacation Mode (for example, in models Liebherr), turn it on when you leave for a long time. temperature +15°C, preventing the formation of mold.

FAQ: answers to frequently asked questions

Can a steam generator be used for cleaning the refrigerator?

Yes, but with caution. The steam generator perfectly removes grease and disinfects, but:

• Do not direct the steam jet at sealing rubber - it may become deformed.
• For No Frost use the minimum power so as not to damage the ventilation ducts.
• After treatment, wipe the surfaces with a dry cloth.

It is better to choose models with temperature control (for example, Karcher SC 3).

Why does there be a smell after cleaning with vinegar became even worse?

This happens if:

• You did not rinse the surfaces with clean water after using vinegar.
• You used undiluted vinegar for plastic parts (it can “burn” the coating).
• There were products with a strong aroma left in the refrigerator (for example, smoked fish) that reacted with vinegar.

Solution: rinse the refrigerator with water and soda (1 tbsp per 1 liter) and ventilate for 2-3 hours.

How to remove the smell from a new refrigerator?

New refrigerators (especially models Haier, Hisense or Beko) often smell like plastic or paint. To eliminate:

1. Wipe all surfaces with a solution of water and lemon juice (1:1).
2. Put bowls of rice or activated carbon on the shelves for 2-3 days.
3. Ventilate the refrigerator with the door open for 12-24 hours.
4. If the smell remains, repeat the procedure by adding 1-2 drops of eucalyptus essential oil to the water.

Usually the “factory” smell disappears after 1-2 weeks of regular use.

Do refrigerator fragrances help?

Flavors (for example, Air Wick or Glade) mask the smell, but do not remove its cause. Moreover:

• They can mix with the original smell and give an even more unpleasant “amber.”
• Strong fragrances permeate foods (especially butter, cheese, bread).
• Some flavors contain alcohol, which spoils plastic.

It is better to use absorbers (soda, coal, zeolite), not masking agents.

What to do if the smell comes from the drainage hole?

The drainage hole (usually located on the back wall of the refrigerator) is often clogged with organic residues, which leads to a putrid odor. To clean:

1. Unplug the refrigerator.
2. Find the hole (in some models, for example ATLANT, it is hidden behind the panel).
3. Clean it with a cotton swab or with a special brush (comes with some refrigerators).
4. Rinse the hole with a soda solution (1 teaspoon per glass of water) using a syringe without a needle.
5. Dry with a hairdryer (cold air!) or a napkin.

If the hole is too strong clogged, use wire with a diameter of 2-3 mm, but act carefully so as not to damage the tube.
