The smell of herring in the refrigerator is one of the most persistent and unpleasant problems that housewives face. The fishy aroma penetrates plastic, rubber seals and even absorbs into the walls of the chamber, remaining for days and weeks. Moreover, ordinary airing or wiping with a damp cloth is not enough here: targeted actions are needed using proven absorbers and special techniques.
In this article we will analyze 10 effective ways from improvised means (soda, vinegar, coffee) to professional odor neutralizers, and we will also tell you how to prevent the reappearance of fishy “amber.” We will pay special attention know-how to refrigerators with system No Frost and models with carbon filters, where standard methods may not work. If you have already tried to get rid of the smell without success, here you will find solutions that are not written about in typical “advisors”.
Why is the smell of herring so difficult to remove?
Herring aroma belongs to the category lipophilic odors —it easily binds to fats and proteins that remain on the surfaces of the refrigerator even after visually thorough cleaning. Unlike, for example, the smell of onions or garlic, the fish “bouquet” consists of volatile amines (trimethylamine, ammonia) and sulfur-containing compounds, which:
- 🧪 Penetrate into micropores plastic and rubber, especially in the door sealing rubber.
- 🌀 Circulate with air flows in systems No Frost, settling on the evaporator.
- 🕒 Activated when the temperature rises (for example, during defrosting).
In addition, in refrigerators with dynamic cooling (for example, models Samsung Twin Cooling Plus or LG DoorCooling+) the smell spreads faster due to forced ventilation. And if the herring was stored in an open container or poorly packaged, the aroma is absorbed into plastic shelves and egg containerswhich are often overlooked during cleaning.
Preparing the refrigerator: what to do before processing?
Before using odor absorbers, the refrigerator must be properly prepared. Neglecting this stage reduces the effectiveness of all further actions by 60-70%:
- Turn off the power and take everything out products. If the refrigerator is No Frost, it is enough to switch it to mode
Holiday(if there is one) or simply open the door. - Remove all removable elements: shelves, drawers, racks, egg containers. They need to be washed separately in warm water with detergent (for example, Fairy or Somat).
- Wipe the walls and the seal a solution of baking soda (2 tablespoons per 1 liter of water) or vinegar (1:1 with water). For sealant, use toothbrush —the most bacteria accumulate in its bristles.
- Check the drainage hole (usually located at the back, under the bottom shelf). Clogged drainage is a breeding ground for odors. Clean it with a cotton swab. or with a pipe cleaner.
If the refrigerator has one built-in carbon filter (for example, in models Bosch VitaFresh or Liebherr BioFresh), it must be replaced - even if its service life is still has not expired. Fish amines “poison” the carbon, and the filter stops working.
☑️ Preparing the refrigerator for processing
Top 5 available means for neutralization odor
Do not rush to buy expensive absorbers - ordinary products that you have in the kitchen often help. The main rule: the product should not mask, but destroy odor molecules.
| The product | How to use | Exposure time | Efficiency (1–5) |
|---|---|---|---|
| Baking soda | Place in open containers on each shelf (2-3 tablespoons). | 12–24 hours | 4 |
| Vinegar 9% | Wipe the walls with a solution (1:1 with water), then put the open bottle inside. | 6–8 hours | 5 |
| Natural coffee | Scatter the grains or thick on a plate. | 24–48 hours | 3 |
| Activated carbon | Crush 10–15 tablets, scatter on shelves. | 12 hours | 5 |
| Citric acid | Dissolve 1 packet in 1 liter of water, wipe all surfaces. | 4–6 hours | 4 |
Vinegar and soda —leaders in effectiveness, but they have nuances. Vinegar removes odor due to an acidic reaction, but its vapors can be absorbed into the plastic if. over-expose. Soda acts more gently, but takes longer. Coffee i charcoal absorb odors physically, but do not destroy their source - they are best used in combination with other methods.
Professional odor absorbers: what to choose?
If improvised means did not help, It's time to move on to the “heavy artillery.” Modern absorbers work on the basis of:
- 🔬 Photocatalysis (destroy odors under the influence of light, for example, Xiaomi Mi Air Purifier Filter).
- 🧂 Zeolites (minerals with a porous structure, absorb amines, for example, Topperr 3104).
- 🌿 Plant enzymes (decompose organic molecules, for example, Bio-Mist).
For refrigerators are optimal:
- Topperr 3104 —zeolite-based absorber. Works up to 3 months, removes even old odors. Suitable for No Frost.
- Zepter Bio Mite —enzyme spray. Applied to surfaces, decomposes protein compounds.
- Fridge Fresh —gel absorber with activated carbon. Can be attached to the wall with a magnet.
When choosing, pay attention to area coating (indicated on the package). For a refrigerator with a volume of 200–300 liters, you need an absorber with a radius of at least 1.5 m. If the model has freshness zone (for example, Samsung CoolSelect Zone), place an additional mini-absorber there.
How to check the authenticity of the absorber?
Original products (for example, Topperr or Fridge Fresh) have a hologram on the packaging and a certificate of conformity. Counterfeits are often sold without markings or with typos in the name.
Features of cleaning refrigerators No Frost and with carbon filters
In refrigerators with a system No Frost (for example, Indesit NBA 18 or ATLANT XM 4021-000) the smell of herring behaves differently due to forced air circulation. ordinary cleaning is ineffective - you need:
- Treat the evaporator (hidden behind the back panel). Wipe it with a vinegar solution or a special product No Frost Cleaner.
- Replace or wash the fan. In models with Multi Air Flow (for example, Samsung RB37J5240SA), the fan blades accumulate grease and odors.
- Use an absorber with forced circulation, for example, Topperr 3108 with a fan.
In refrigerators with carbon filters (series Liebherr BioFresh, Bosch VitaFresh) the herring smell often remains even after replacing the filter. In this case:
- 🔄 Rinse the filter in a soda solution (if it is reusable).
- 🔥 Warm up the zeolite-based filter next to the main one. in the oven at 100°C for 10-15 minutes (only for ceramic filters!).
- 🛠️ Install an additional filter based on zeolite next to the main one.
What should not be done when removing the smell?
Some “folk” tips not only do not help, but can also ruin the refrigerator. Avoid these mistakes:
⚠️ Attention: Never use chlorine-containing products (for example, White) to clean the refrigerator. Chlorine reacts with plastic to form toxic compounds and damage the rubber seal. For disinfection, use only hydrogen peroxide (3% solution).
- ❌ Try to “kill” the smell with fragrances (vanilla, citrus peels). This will only mix the odors, making the “bouquet” even more persistent.
- ❌ Use abrasive sponges to clean plastic - they leave microcracks into which dirt is later absorbed.
- ❌ Close the refrigerator immediately after processing. Let it ventilate for at least 2-3 hours with the door open.
Also, do not:
- 🚫 Place open containers with ammonia - its vapors can damage electronic components (for example, the display in models Samsung Family Hub).
- 🚫 Use a steam generator for cleaning - moisture can get into the electrical contacts.
Prevention: how to store herring so that there is no smell?
The best way to deal with the smell is to prevent its appearance. Follow these rules:
- Pack the herring hermetically:
- 🥫 Glass jar with a screw cap - the best option.
- 📦 Vacuum bag (if there is a vacuum sealer) or a zip-lock with a double clasp.
- 🧊 Food container with a silicone gasket (for example, Tupperware or Lock&Lock).
Fresh Balancer).If the herring is stored longer than 2-3 days, rinse it under running water every 24 hours - this removes surface bacteria that enhance the odor. You can also spray the fish lemon juice solution (1 tablespoon per 200 ml of water) - the acid neutralizes amines.
FAQ: Frequently asked questions about the smell of herring in the refrigerator
Is it possible to use scented candles or air fresheners for the refrigerator?
No, this will only worsen the problem (for example, Air Wick or Glade) mask the odor, but do not remove its source. In addition, their chemical components can react with fish amines, creating a new unpleasant odor. Use only absorbersand not masking agents.
Does ozonizer help remove odor? herring?
Ozonators (for example, Timberk TOS-O707) are effective against odors, but they must be used with caution:
- ✅ Kills bacteria and decomposes organic odor molecules.
- ⚠️ After treatment, the refrigerator must be ventilate at least 4–5 hours —ozone is toxic.
- ❌ Not suitable for refrigerators with air ionizers (for example, Panasonic NR-BN34AW1) - may cause the system to fail building.
It is optimal to use an ozonizer once every 2-3 months for prevention, and not as the main remedy.
How long will it take for the smell of herring to disappear on its own if you do nothing?
It all depends on the model refrigerator and odor intensity:
- 🕒 In ordinary refrigerators (without No Frost) - after 1-2 weeks, but only if the fish was well packaged.
- 🕒 In refrigerators No Frost - up to 1 month, since the smell circulates with the air.
- 🕒 If the herring was stored open, the smell may remain forever, penetrating into the plastic and seals.
Without active action, the smell will not disappear completely - it will simply become less noticeable, but will return when the temperature rises (for example, when defrosting).
Is it possible to wash the inside of the refrigerator with a washing vacuum cleaner (for example, Karcher)?
Technically possible, but with reservations:
- ✅ Suitable for removable shelves and containers - the vacuum cleaner quickly removes grease and food debris.
- ⚠️ Do not direct the water jet on:
- 🔌 Electronic panels (in models with a display, for example, Samsung RF23J9011).
- 🧊 Drainage hole - you can clog it with debris.
- 🔄 Ventilation grilles in No Frost.
- ❌ Do not use hot water - it can deform plastic.
After vacuuming, be sure to wipe the surfaces with a dry cloth and ventilate the refrigerator for 3-4 hours.
Is it true that the smell of herring can spoil other products?
Absolute truth. Fish amines and sulfur-containing compounds:
- 🧀 Absorbed into fats - butter, cheeses, sausages begin to taste like fish.
- 🥛 Spoils dairy products - yoghurts, sour cream will sour faster.
- 🍎 Accelerates the rotting of fruits and vegetables —ethylene (the gas released by fruits) reacts with amines.
If the herring was stored open, throw away all unpackaged foods, especially:
- 🥩 Meat and poultry (absorb the smell in 6-12 hours).
- 🥚 Eggs in the shell (pores let amines through).
- 🍞 Bread and pastries (the porous structure retains the smell).
Products in sealed packaging (vacuum bags, glass jars) can be saved if you rinse the outside of the packaging with a soda solution.
