How to remove the smell from the refrigerator: proven methods and mistakes that aggravate the problem

An unpleasant odor in the refrigerator is a problem that every second person faces home cook. It appears suddenly: either because of a fish forgotten on a shelf, or after a power outage, or simply “on its own.” But getting rid of it is not as easy as it seems. Normal airing or washing the shelves often gives a temporary effect, and after a couple of days the “aroma” returns with renewed vigor.

In this article - 10 working methods eliminate the smell (including emergency and preventive), analysis of the reasons for its appearance, as well as typical mistakesthat only intensify the problem. All methods have been tested on refrigerators of different brands - from Samsung i LG to budget ATLANT i Indesit. No “magic chemistry” - only available means and clear instructions.

Important: if the smell is accompanied mold on the seal or constant moisture inside the chamber, the problem may be deeper - in malfunction of the system No Frost or drainage hole. In this case, after cleaning, be sure to check these components (instructions are in the relevant sections).

Why an unpleasant odor appears in the refrigerator: 5 main reasons

Before dealing with the consequences, Let's figure out the reasons. The smell rarely occurs “just like that” - it is usually preceded by one or more operational errors:

• 🍳 Spoiled products. Even a small piece of meat or fish, forgotten on the back shelf, can become a source of lasting “amber.” It is especially dangerous if the product begins to rot in a closed package - the smell penetrates the plastic and rubber parts.
• 🧊 Improper defrosting. If the refrigerator was defrosted in a hurry (for example, the ice was scraped off with a knife) or was not dried after washing, moisture remains in the cracks and becomes a breeding ground for bacteria.
• 🧽 Contaminated drainage. The condensate drain hole (usually at the bottom of the back wall) becomes clogged with crumbs and grease. The water stagnates, mold appears - and as a result: the smell of dampness.
• 🔄 Impaired air circulation. Too tight packaging of products or improper placement (for example, hot dishes on the top shelves) leads to “stagnation” of air and accumulation of odors.
• 🦠 Bacteria and fungus. If the refrigerator is not washed regularly (at least once every 2-3 months), a biofilm forms on the walls and seal - a thin film of microorganisms, which gives a persistent “rotten” aroma.

Interesting fact: in refrigerators with the system No Frost an odor appears less often, but if it does occur, it is more difficult to eliminate. The fact is that in such models, air circulates through closed channels, and the “aroma” penetrates deeper - into the ventilation grilles and evaporator.

Emergency methods: how to remove the smell in 1-2 hours

If the smell needs to be eliminated urgently (for example, before guests arrive), use one of these methods. They will not solve the problem forever, but will give a temporary respite:

1. Vinegar + soda: classic duet

Mix in equal proportions 9% vinegar and baking soda (2 tablespoons per 1 liter of water). Wipe all surfaces with the solution, including the rubber seal and shelves. Vinegar kills bacteria, and baking soda neutralizes odors. After treatment, wipe the refrigerator with clean water and leave the door open for 30–40 minutes to ventilate.

2. Citric acid for persistent “flavors”

Dilute 2 tbsp. spoons citric acid in 0.5 liters of hot water. Wipe down the walls and shelves with the solution, paying special attention to corners and seams. The acid not only eliminates odor, but also dissolves fatty deposits. Do not use this method if there are aluminum parts in the refrigerator - citric acid can damage them.

3. Activated carbon is a natural absorbent

Place on shelves and door compartments 10-15 tablets of activated carbon (can be crushed into powder). Charcoal will absorb odors in 1–2 hours. To enhance the effect, add a few drops of essential oil (for example, tea tree or lavender).

Unplug the refrigerator

Take out all the products and shelves

Wipe the walls with vinegar or soda solution

Rinse the drainage hole

Spread out the absorbent (charcoal, soda)

Leave the door open for 30-60 minutes-->

Deep cleaning: step-by-step instructions for eliminating odor forever

If emergency measures did not help or the smell returns regularly, it’s time to carry out complete disinfection. This method takes 3-4 hours, but is guaranteed to solve the problem.

Step 1: Preparation

Unplug the refrigerator, remove all food and shelves. If possible, move the cleaning to a balcony or a well-ventilated area - this way you will avoid the smell spreading throughout the kitchen. Prepare:

• 🧴 Washing agent (vinegar, soda, a specialized cleaner like Topperr 3101 or Sano Refrigerator Cleaner)
• 🧽 Soft sponges and rags (do not use hard brushes - they scratch the plastic)
• 🪥 Toothbrush for cleaning drainage and seal
• 🧤 Rubber gloves (some products can corrode the skin)

Step 2: Cleaning internal surfaces

Apply detergent to walls, shelves and doors compartments. Pay special attention to:

• 🔍 Sealing rubber - it must be cleaned on both sides with a toothbrush dipped in vinegar or a common solution (1 teaspoon of common vinegar per 1 liter of water).
• 🕳️ Drainage hole - clean it with a cotton swab or a special one. brush (can be used for this purpose cleaning pipes from a 3D pen).
• 🧊 Back wall - if the refrigerator has a drip system, dirt and mold often accumulate there.

After treatment, wipe all surfaces with clean water and dry with paper towels. Do not turn on the refrigerator until it is completely dry! Moisture is the main ally of bacteria.

Step 3: Disinfection and odor neutralization

After washing, use one of the products for final treatment:

After disinfection, spread on the shelves natural absorbents:

• ☕ Ground coffee - absorbs odors and leaves a pleasant aroma (change every 2-3 days).
• 🍋 Citrus zest —lemon or orange peel not only smells pleasant, but also inhibits the growth of bacteria.
• 🌿 Bunches fresh herbs (parsley, mint) is a natural freshener, which is also safe for food.

How to clean the drainage hole: step-by-step instructions

A clogged drainage hole is one of the main reasons for the persistent smell of dampness. Normally, condensation drains through it, but if it is clogged, water accumulates at the bottom of the refrigerator, creating ideal conditions for mold.

To clean the drain:

1. Unplug the refrigerator and remove all shelves.
2. Locate the hole - it is usually located in the center of the back wall (in models with drip system) or under the vegetable drawer (in No Frost).
3. Take a cotton swab, toothpick or special brush and carefully clean the hole by rotating the tool clockwise.
4. Rinse the drainage with warm water and soap, using a syringe or syringe without a needle.
5. Check whether the water flows freely - to do this, pour a little water into the hole. If it drains quickly, the drainage is clear.

If the drainage is heavily clogged (for example, with a plug of fat and crumbs), you can use wire with a diameter of 2-3 mm, but act carefully so as not to damage the tube. In extreme cases, contact a specialist - in some models (Liebeherr, Bosch) the drainage system is complex and can be easily broken.

What to do if there is no drainage hole?

In refrigerators with a system Full No Frost (for example, Samsung RB37J5230there is no drainage hole inside the chamber - moisture evaporates automatically. However, the smell can come from evaporator, which is located behind the back panel. In this case, only professional cleaning or replacing the filter (if provided). design).

Folk remedies vs professional chemistry: which is more effective?

Many housewives prefer to make do with improvised means, but sometimes they cannot do without “heavy artillery” Let’s compare:

Conclusion: for preventive cleaning folk remedies are suitable, but if the smell is persistent (for example, from rotten meat or mold), it is better to use professional chemistry. The best option is Topperr 3101 or Whiteness (diluted 1:10), but after them the refrigerator must be thoroughly washed.

What NOT to do: 5 mistakes that aggravate the problem

Some actions that seem logical are actually only increase the smell or spoil the refrigerator. Avoid these mistakes:

⚠️ Attention! Never use Abrasive powders (type Pemolux) or metal sponges to clean the refrigerator. They scratch the plastic, and bacteria then accumulate in microcracks, increasing the smell.

• 🚫 Close the refrigerator immediately after. washingThe humidity inside is an ideal environment for mold. Always dry the chamber for at least 30 minutes.
• 🚫 Use alcohol-based fragrances. Alcohol can react with plastic, and the smell will become even worse.
• 🚫 Put in the refrigerator. open soda or coalThey absorb not only odors, but also moisture, which leads to the formation of condensation.
• 🚫 Ignore the sealing rubber. It is in its folds that dirt and mold most often accumulate.
• 🚫 Wash the refrigerator with hot water. water. A sharp temperature change can damage the plastic and cause deformation of the shelves.

Another common mistake is use of air fresheners instead of cleaning. Sprays like Glade or Air Wick only mask the smell, but do not eliminate its cause. by force.

Prevention: how to prevent the appearance of odor

The best way to deal with odor is to prevent it from appearing. Just follow these simple rules:

1. Check the products once a weekThrow away everything that begins to deteriorate, even if the expiration date is not yet reached. expired. Please note:
• 🥩 Meat and fish - they spoil the fastest.
• 🧅 Onions and garlic - their pungent smell is absorbed into the plastic.
• 🥛 Dairy products - even a small mold on cheese can spoil the air in the entire refrigerator.

Store food in airtight containers. This is especially true for fish, meat, cheeses and prepared foods. Glass or plastic boxes with silicone gaskets are suitable (for example, Tupperware or Lock&Lock).

Wash the refrigerator regularly. The optimal frequency is once every 1-2 months. Use mild detergents and always dry the camera after washing.

Keep an eye on the drainage. hole. Clean it once every 3 months, even if there is no smell.

Use absorbents. Keep an open pack of soda, charcoal or special odor absorbers in the refrigerator (for example, Fridge Fresh).

Do not put hot food. Wait until the food has cooled to room temperature - this will prevent the formation of condensation.

If your refrigerator has a function Antibacterial protection (for example, in models LG InstaView or Samsung Twin Cooling Plus), do not rely on it completely. This system reduces the rate of bacterial growth, but does not replace the regular one. cleaning.
