How to get rid of the smell in a refrigerator: step-by-step instructions with proven means

An unpleasant odor in the refrigerator is a problem that almost every home cook faces. Even with regular cleaning, aromas from spoiled food, fish or spices can be absorbed into plastic, rubber seals and remain for a long time. But do not rush to throw away the equipment or spend money on expensive services of specialists: you can eliminate the smell yourself with the help of improvised means and the correct cleaning technology.

In this article we will analyze not only the classic methods (soda, vinegar, lemon), but also less known, but no less effective methods - from coffee grains to hydrogen peroxide. You will learn what mistakes lead to the reappearance of the smellhow to properly wash shelves and seals, and also receive a checklist for prevention. We will pay special attention safetyto: which products cannot be mixed and which are ideal for refrigerators with a system No Frost.

If you have already tried a soda solution, but the smell returned after a week - do not despair. You may have missed a key step, which we will discuss below. And for owners of refrigerators with antibacterial coating (for example, models Samsung RB30A3200SA or LG GA-B409SLGL), we have prepared separate recommendations.

Why does an unpleasant smell appear in the refrigerator?

Before you start cleaning, it is important to understand the source of the problem. The smell rarely occurs on its own - it is usually the result of a combination of factors:

• 🍳 Spoiled products - even a small piece of meat or fish forgotten on the back shelf can become a breeding ground for bacteria. It is especially dangerous if the product “drips” - the liquid is absorbed into the plastic.
• 🧽 Untimely cleaning - drops from juice, milk or sauces, if not wiped off immediately, oxidize and begin to “smell.”
• 🧊 Ice and condensation - in In refrigerators without No Frost ice accumulates odors, and when defrosting they are released.
• 🦠 Mold and bacteria - most often accumulate in the sealing rubber, on the back wall or in the drainage hole.
• 🧴 Chemical reactions —for example, if you store onions and apples nearby, they emit gases that accelerate each other's spoilage.

Interesting fact: in refrigerators with ion filters (for example, Panasonic NR-BN30A1) the smell appears less often, but even they require periodic cleaning. But models with carbon filters (like Bosch KAN92VI30R) can themselves become a source of aroma if the filter is not changed on time.

Preparing the refrigerator for cleaning: 5 mandatory steps

You can't just take a sponge and wipe the shelves - improper preparation will negate all efforts. Follow this algorithm:

1. Unplug the refrigerator and get all the products. If it's hot outside, put perishable foods in a cooler bag or a bowl of ice.
2. Remove all removable elements: shelves, drawers, racks, egg tray. They need to be washed separately.
3. Allow the refrigerator to thaw (if there is ice). Do not use a hairdryer or hot water - this may damage the seal.
4. Check the drainage hole (usually located on the back wall). If it is clogged, the smell will return. Clean it with a cotton swab or a special brush.
5. Get access to the back wall —dust and mold often accumulate there, which can also be a source of odor.

⚠️ Attention: If your refrigerator has a system No Frost, do not try to mechanically remove frost from the back wall - this may damage the evaporator. Simply wipe it with a soft cloth.

Top 7 folk remedies for eliminating odor

Homemade remedies often work no worse than professional ones, but it is important to know concentration and exposure time. Below are proven recipes with explanations of when to use them.

💡 Tip: To enhance the effect, combine products. For example, first wash the refrigerator with a soda solution, then place a saucer with charcoal and lemon slices on the shelf.

Professional remedies: when traditional methods do not help

If the smell is persistent (for example, from rotten fish or spilled milk), and home methods did not work, it’s time to move on to “heavy artillery.” Professional products are divided into 3 types:

• 🧴 Gels and sprays - convenient for quick processing. Examples: OdorGone, Fresh GelApply for 10-15 minutes, then wash off.
• 🧽 Foams and mousses - suitable for deep cleaning. For example, Sano Refrigerator Cleaner forms foam that penetrates microcracks in plastic.
• 🔬 Antibacterial wipes - are impregnated with a special composition that kills up to 99% of bacteria. Brands: Clorox, Lysol.

⚠️ Attention: Do not use products with chlorine (for example, Whiteness) to clean the refrigerator! Chlorine can:

• Corrode plastic and rubber parts;
• React with food residues and release toxic gases;
• Leave a persistent chemical odor that will be absorbed into food.

For refrigerators with silver coating (for example, Liebherr CBPes 4056) select products marked for antibacterial surfaces. Aggressive chemicals can damage the protective layer.

What to do if the smell remains after cleaning?

If after general cleaning the smell returns after 1-2 days, the problem lies hidden deeper:

1. Check drainage tube - rot often accumulates there. Clean it with wire and rinse with soda solution.

2. Inspect the back wall for the presence of mold (especially if the refrigerator is in a damp room).

3. Perhaps the smell comes from evaporator - in this case, only professional cleaning or replacement of the part will help.

How to wash the rubber seal: step-by-step instructions

The seal is the “dirtiest” place in the refrigerator. Crumbs, grease and bacteria accumulate here, which cannot be removed with a regular sponge. You need to clean the rubber band separately:

1. Moisten a rag in a warm soapy solution (or with a 1:1 vinegar solution) and thoroughly wipe all the folds of the seal. For hard-to-reach places, use cotton swabs.
2. Apply baking soda paste (mix baking soda with water to the consistency of toothpaste) on the elastic band, leave for 10 minutes.
3. Wipe with a brush with soft bristles (for example, a toothbrush), paying attention to the joints.
4. Rinse with clean water and wipe dry. It is important to remove all remaining soda - it can dry out and begin to crumble.
5. Apply silicone grease (for example, WD-40 Specialist) on a dry rubber band - this will prevent cracking and extend the service life.

🔍 Signs that it is time to change the seal:

• The rubber has become stiff and does not return to its original position after pressing;
• Cracks or tears have appeared on it;
• The refrigerator door closes not tightly (you can check with a sheet of paper - if it falls out easily, the seal is faulty).

Cleaning the drainage hole: why is this important?

The drainage hole is the main “culprit” of persistent odors in 70% of cases. It is needed to drain condensate, but if it gets clogged, water stagnates, and the process of rotting begins. How to clean:

1. Unplug the refrigerator and find the hole (usually at the bottom of the back wall, under the plastic panel).
2. Take a cotton swab or a special brush (included with some models, for example, Samsung RB37J5240SA).
3. Carefully clean the hole by rotating the stick. If the blockage is severe, use a wire (but not metal!).
4. Pour a soda solution into the hole (1 tsp per glass of water) using a syringe or syringe.
5. Rinse with clean water and check if the water leaves (pour a little into the hole - it should drain quickly).

⚠️ Attention: If after cleaning the water still does not drain, the drainage hose may be clogged. In this case, it is better to call a specialist - independent attempts to clean it can damage the system.

💡 Advice for No Frost refrigerators: In such models, the drainage hole is often hidden behind the back panel. To get to it, carefully remove the panel (usually it is secured with latches).

Prevention of odors: how to prevent recurrence

Cleaning the refrigerator is only half the battle. If you don’t change your habits, the smell will return in 1-2 weeks. Here are 8 rules that will help avoid the problem:

• 📅 Regular cleaning - wash the refrigerator at least once a month for daily care, just wipe the shelves with a damp cloth.
• 🥩 Proper food storage —store meat, fish and cheeses in airtight containers. For vegetables, use special boxes with controlled humidity.
• 🧊 Humidity control —if condensation accumulates in the refrigerator, place a moisture absorber. (for example, Silica Gel).
• 🍋 Natural flavors - put a lemon slice, orange peel or bag of coffee beans on the shelf. Change them once a week.
• 🔍 Checking expiration dates - check once a week products. Throw away anything that is in doubt.
• 🧻 Dry shelves —before putting food back, make sure all surfaces are dry. Moisture accelerates the growth of bacteria.
• 🌡️ Temperature conditions —maintain the temperature. +4...+5°C in the main chamber and -18°C in the freezer. At higher values, food spoils faster.
• 🛠️ Maintenance - check the seal and drainage hole every six months If the refrigerator is No Frost, defrost it once a year. prevention.

📌 Useful life hack: Buy cat litter based on zeoliteat the pet store. Pour it into a small bag and place it on the bottom shelf - it perfectly absorbs odors and moisture.

FAQ: Frequently asked questions about odors in the refrigerator

Can I use bleach to clean the refrigerator?

No, bleach (including Whiteness) is not suitable for refrigerators. It can:

• Damage plastic and rubber parts;
• Leave a toxic odor that will be absorbed into food;
• React with food residues and release chlorine gas.

Use instead baking soda or special detergents for refrigerators.

How to remove the smell of plastic in a new refrigerator?

The smell of new plastic (especially strong in models Haier or Vestfrost) usually disappears after 1-2 weeks. To speed up the process:

• Rinse the refrigerator with a solution of vinegar (1:1) and leave the door open for 2-3. hours;
• Place a bowl with activated carbon or coffee beans on the shelf;
• Wipe the surfaces with lemon juice - it neutralizes the chemical odor.

Do not use aggressive detergents - they can damage the new coating.

What what to do if the smell comes from the freezer?

The smell in the freezer is usually associated with:

• Spoiled food - even when frozen they can “smell”;
• Ice - absorbs odors, like sponge;
• Faulty defrosting system (if the freezer No Frost).

What to do:

1. Defreeze the freezer, remove everything products;
2. Rinse the shelves and walls with a solution of soda or vinegar;
3. Check for smudges under the drawers - rot often accumulates there;
4. If the smell remains, put a bag of soda in the freezer for 12 hours.

Do air ionizers for the refrigerator help?

Ionizers (for example, Xiaomi Viomi Mini Fridge Deodorizer) really help fight odors, but:

• They do not replace cleaning only mask odors;
• Effective only with regular use (need to be turned on once every 1-2 days);
• Some models can dry products (for example, greens or fruits).

If you decide to buy, choose devices with UV lamp —they not only ionize, but also kill bacteria.

How often do you need to change the filter in a refrigerator with an air purification system?

Filter service life depends on the model:

• Carbon filters (for example, in Samsung RB30J3000WW) - once every 6 months;
• Antibacterial filters (as in Panasonic NR-BN30A1) - once every year;
• Photocatalytic filters (y Sharp SJ-FP65PVSL) - once every 2 years.

💡 Signs that it is time to change the filter: odor began to appear more often, it formed faster on the walls of the refrigerator condensation, food spoils faster than usual.
