How to remove a bad smell from a refrigerator: 10 working methods and prevention

An unpleasant odor in the refrigerator is a problem that almost everyone faces. Even with regular cleaning, the aromas of spoiled food, fish or spices can be absorbed into plastic, rubber seals and remain for a long time. But why does the smell appear even in a clean refrigerator? The fact is that bacteria and mold develop not only on visible surfaces, but also in hard-to-reach places: under vegetable drawers, in the drainage hole or on the back wall.

In this article we will look 10 proven methodshow to remove odor from the refrigerator - from improvised means to professional absorbers. You will learn which methods are suitable for No Frost and drip systems, how to properly wash the rubber seal and what to do if the smell returns after a week. And at the end - a prevention checklist that will help avoid problems in the future.

Causes of unpleasant odor

Before dealing with the smell, it is important to understand its source. The most common culprits are:

• 🍎 Spoiled food —even a small piece of moldy cheese or sour milk can become a source of odor.
• 🧽 Contaminated drainage hole —if it is clogged, the water stagnates and a musty aroma appears.
• 🧼 Improper cleaning —the use of aggressive detergents (for example, bleach) can react with the plastic and increase the smell.
• 🔄 Violation air circulation —if the refrigerator is full of food or is located close to the wall, the moisture does not evaporate and dampness appears.

Refrigerators with the system No Frostare especially vulnerable: in them the smell can spread through the air ducts. And in models with a drip system (for example Atlant or Biryusa) drainage often suffers - it needs to be cleaned every 2-3 months.

Preparing the refrigerator for cleaning: 5 mandatory steps

Before eliminating the smell, the refrigerator must be properly prepared. Skip this step - and all efforts may go down the drain.

1. Unplug and take out all the products. If the refrigerator No Frost, wait 1-2 hours until the ice melts naturally.
2. Remove all removable elements: shelves, drawers, grilles. They need to be washed separately in warm water with soda or vinegar.
3. Check the drainage hole (usually located on the back wall). If it is clogged, clean it with a cotton swab or a special brush.
4. Remove visible mold with a dry cloth, then treat these places with hydrogen peroxide or alcohol.
5. Wipe the sealing gum —namely This is where most bacteria accumulate. Use a toothbrush with soda solution.

Important: never wash the refrigerator with hot water - this can deform the plastic and damage the thermostat. The water temperature should not exceed 40°C.

Top 5 folk remedies for eliminating odor

If the smell is fresh and not too persistent, you can get by with improvised means. They are safe for health and do not require large expenses.

To enhance the effect, you can combine products. For example, first wash with vinegar, then wipe with soda and leave activated carbon overnight.

Professional odor absorbers: what to choose?

If traditional methods do not help, you should turn to specialized products. They come in three types:

• 🧴 Gels and liquids (for example, OdorGone or SmellOff) - applied to surfaces and neutralize odor at the chemical level.
• 📦 Insert absorbers (for example, Bork K700 or Topperr 3104) - are installed inside the refrigerator and work for up to 3 months.
• 🔋 Ultraviolet and ozonizers (for example, Xiaomi Deodorizer) - kill bacteria and viruses, but require connection to electricity.

When choosing, pay attention to:

• Validity period (from 1 month to a year).
• Compatibility with your refrigerator model (some products are not suitable for No Frost).
• The presence of fragrances - they can mask the smell rather than eliminate it.

Lifehack: if you don’t want to spend money on professional products, buy silica gel (the same bags that are put in shoe boxes). It perfectly absorbs moisture and odors. The main thing is to dry it in the oven regularly.

Why is an ozonizer dangerous for a refrigerator?

Ozonators really kill bacteria and eliminate odors, but if used incorrectly they can:

- Damage rubber sealants (ozone oxidizes rubber).

- Leave a metallic taste in food if you do not ventilate the refrigerator after processing.

- Cause headaches when inhaling high concentrations of ozone.

Use them only in an empty refrigerator and strictly according to instructions!

How to get rid of persistent odors (fish, garlic, mold)?

Some odors - for example, from fish, garlic or sour meat - eat into plastic and rubber so much that ordinary cleaning does not help. In such cases, an integrated approach is needed:

1. Deep. cleaning with disassembly:
   • Remove the entire back panel (in models with a drip system) and rinse the drainage tube.
   • Remove fan (in No Frost) and clean the blades with a cotton swab dipped in alcohol.
   • Wipe condenser (grid at the back of the refrigerator) - dust accumulates there, which intensifies the smell.
2. Disinfection:
   • Use chlorhexidine (0.05%) or miramistin for processing plastic.
   • Suitable for rubber sealant ammonia (1 tsp per glass of water).
3. Long-term treatment:
   • After cleaning, leave the refrigerator open for 12–24 hours with a packet of soda or charcoal.
   • If the smell remains, repeat the procedure with hydrogen peroxide (3%) - it decomposes organic compounds.

For Samsung refrigerators with the system Twin Cooling Plus and LG with DoorCooling+ there is a nuance: the smell can spread through individual air ducts In this case, only complete defrosting (even for No Frost) and cleaning using a steam generator will help.

What should not be done when cleaning the refrigerator?

Some “folk” advice may not only not help, but also aggravate the problem. This is what is strictly prohibited:

⚠️ Attention: Never use products containing pure chlorine to clean the refrigerator. They destroy plastic, leave toxic fumes and can react with food. bleach or pure chlorine products. They break down plastic, leave toxic fumes, and can react with food.

• 🚫 Wash the refrigerator with hot water - this will deform the seal and can damage the thermostat.
• 🚫 Use abrasive sponges —they scratch the surface, and dirt then gets stuck into the microcracks.
• 🚫 Close the refrigerator immediately after cleaning —moisture will not evaporate and dampness will appear.
• 🚫 Place open containers with vinegar or ammonia for a long time — their vapors can damage electronic components.

Also, do not rely on flavors (vanillin, essential oils). They only mask the smell, but do not eliminate its cause. The exception is special absorbers with an antibacterial effect.

Prevention: how to prevent the appearance of odor?

In order not to fight the odor every few months, just follow simple rules:

• 📅 Regular cleaning - wash the refrigerator every 1-2 months (for No Frost - once every 3 months).
• 🥩 Proper storage of food:
  • Keep meat and fish in airtight containers or vacuum bags.
  • Wrap cheeses and sausages in parchment, not in plastic.
  • Store fruits and vegetables in special boxes (do not mix, for example, apples and carrots - they spoil faster together).
• 🌡️ Temperature control —in the main one there should be +2…+5°Cin the camera, and -18°Cin the freezer. At higher values, food spoils faster.
• 🔄 Ventilation —do not place the refrigerator close to the wall (minimum distance - 5 cm) and do not fill it with products to the brim.

For refrigerators with a freshness zone (for example, Liebherr BioFresh or Bosch VitaFresh) there is an additional rule: once a week, wipe this area with a weak solution of vinegar, even if it looks clean. Here the humidity is higher, and bacteria multiply more actively.

FAQ: Frequently asked questions about the smell in the refrigerator

Why does the smell come back a week after cleaning?

Most likely, you have not eliminated the source of the problem. Check:

• Drainage hole - if it is clogged, the water stagnates and the smell appears again.
• Sealing rubber - mold may remain in its folds.
• Food - there may be a spoiled piece lying around somewhere (check the drawers for vegetables and the shelves under them).

If everything is clean, but the smell remains, the reason may be faulty evaporator or dirty fan (for No Frost).

Can a steam generator be used to clean a refrigerator?

Yes, but with caution:

• Do not direct the steam jet at sealing rubber and electronic elements (display, buttons).
• After treatment, wipe all surfaces dry - moisture can cause corrosion of metal parts.
• Do not use the steam generator for refrigerators with metal walls (for example, some models Smeg or Gorenje) - this can lead to rust.

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

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

• Wipe all surfaces with a solution of vinegar (1:1 with water).
• Place inside orange peels or lemon for 2-3 days.
• Use odor absorber (for example, Topperr 3104).

Do not use aggressive detergents - they can react with plastic and increase the smell.

Does the ozonizer help with smell in the refrigerator?

The ozonator is effective, but has limitations:

• ✅ Kills bacteria and mold.
• ✅ Eliminates even persistent odors (fish, garlic).
• ❌ May damage rubber seals when long-term use.
• ❌ Requires ventilation of the refrigerator after treatment (minimum 1 hour).

Use the ozonator no more than once every 3 months and only in an empty refrigerator.

What to do if the smell comes from the freezer?

The smell in the freezer usually appears due to:

• Spoiled food - even when frozen, food spoils (especially fish and meat).
• Ice with bacteria - when defrosting, microbes are activated.
• Faulty fan (in No Frost) - it can spread the smell throughout the chamber.

What do:

1. Defrost the freezer (even if it is No Frost).
2. Rinse all surfaces with a solution of soda or alcohol.
3. Check drain hole - in freezers Atlant i Stinol it often gets clogged.
