A new refrigerator is always a joy, but it is often overshadowed by a persistent chemical smell of plastic that can last for weeks. This aroma appears due to technological features of production: polymers, adhesives, sealants and even packaging materials emit volatile organic compounds. Models with system No Frost i inverter compressors, where there are more plastic parts than in classic units, “smell” especially strongly.
The problem is not only discomfort - prolonged inhalation of such fumes can cause headaches or allergic reactions reactions. Luckily, there are several proven ways to neutralize odors without damaging your equipment. In this article we will analyze 7 effective methods (from household to professional), tell you what mistakes lead to an increase in the “aroma”, and give a checklist for safely preparing the refrigerator for the first use.
Why a new refrigerator smells like plastic and is it dangerous
The smell appears due to emission of formaldehyde, styrene and other volatile compounds a side effect of the production of plastic parts. Normally, the concentration of these substances is minimal and does not harm health, but when heated (for example, during transportation under the sun) or in a closed space, their amount may increase.
The following are considered especially “fragrant”:
- 🔹 Budget models with thin plastic walls (for example ATLANT XM 4021-000 or Birusa 101).
- 🔹 Refrigerators with No Frost system - due to the abundance of air ducts and fans.
- 🔹 Equipment stored in a warehouse for more than 6 months (even in packaging).
According to Rospotrebnadzor, in 90% of cases the smell disappears on its own after 1-2 weeks with proper use. However, if it persists longer. or intensifies, this may indicate defective door seal or a violation of the assembly technology. In this case, you should contact the brand’s service center (warranty case!).
Preparation of the refrigerator: what to do BEFORE plugging it in
Many turn on the equipment immediately after delivery - and in vain. Plastic and seals must be “ventilated” in disassembled form for at least 12 hours, otherwise the smell will “cook” into the surface and will disappear for months. Follow this algorithm:
Remove all packaging (film, foam, tape)
Remove all shelves, drawers and trays - wash them with warm water and soda
Wipe the inner walls with a soft cloth soaked in a vinegar solution (1:1)
Leave the door open for 12-24 hours in a ventilated area room
Check the seal for oil stains (a sign of defect)
-->
If the refrigerator was delivered in a horizontal position (for example, Liebeherr CUag 3311), before turning it on, you need to let it stand vertically for at least 4 hours - this will allow the oil in the compressor to drain and avoid damage. check:
- 🔌 Socket: it must be grounded and withstand a load of at least 16A.
- 🌡️ Temperature in the room: optimally 18–22°C (at +30°C the plastic “smells” stronger).
⚠️ Attention: If it was included carbon filter (for example, in models Samsung RB30A3200SA), do not rush to install it immediately. Activate the filter only after the factory smell has completely disappeared - otherwise it will quickly clog.
7 ways to remove the smell of plastic: from folk to professional
Methods are divided into three categories: absorbers (absorb the smell), neutralizers (destroy odor molecules) and maskers (interrupt the aroma). We have selected the most effective and safe for technology.
| Method | Action time | Pros | Cons |
|---|---|---|---|
| Activated carbon | 3–5 days | Cheap, environmentally friendly, leaves no traces | You need a lot of tablets (1 package per 10 liters of volume) |
| Citric acid | 12–24 hours | Kills bacteria, refreshes the air | Can damage the rubber seal at high concentrations |
| Ozonizer | 1–2 hours | Destroys 99% of odors and germs | Expensive, requires caution (harmful for people) |
| Soda + vinegar | 6–12 hours | Quickly neutralizes chemical fumes | You need to rinse thoroughly, otherwise the smell will remain |
1. - the best absorber
Crush 10-15 tablets of coal (at the rate of 1 tablet per 1 liter of refrigerator volume), place on plates and place on each shelf. To enhance the effect, add rice groats - it absorbs moisture, which enhances the smell.
2. Citric acid or juice is a natural neutralizer
Dilute 2 tablespoons of citric acid in 1 liter of water and wipe all internal surfaces. An alternative is to cut the lemon in half and place the halves on the shelves for 12 hours. The acid destroys formaldehyde molecules, but do not use this method more than once a week - it can damage the plastic.
3. Baking soda is a universal remedy
Make a paste of soda and water (the consistency of toothpaste), apply to the walls for 30 minutes, then rinse. For prevention, leave an open box of soda in the refrigerator for 1-2 weeks. Soda not only removes the smell, but also prevents the appearance of mold.
4. Vinegar solution - disinfection + refreshment
Mix 9% vinegar with water in a 1:1 ratio, wipe all surfaces and leave the door open for 6 hours. Vinegar is effective against styrene one of the main sources of “plastic” smell. After treatment, wipe the refrigerator with clean water. to remove the pungent aroma.
⚠️ Attention: Never mix vinegar with bleach or ammonia - this releases toxic chlorine!
5. bags
Pour fresh coffee beans into a bowl or place black tea bags on the shelves. Caffeine absorbs odors, and tea essential oils mask them. The method works for 3-5 days, but is only suitable for weak “aromas.”
6. data-i="144">If the smell does not disappear for more than a month, use
If the smell persists for more than a month, use ozonator (for example, AirComfort XJ-3000C). The device generates ozone, which destroys odor molecules. 1-2 hours of operation in a closed refrigerator is enough. Important: after treatment, ventilate the equipment for 3-4 hours, since ozone in high concentrations is harmful.
7. Special odor absorbers
In household chemical stores, absorbers for refrigerators are sold (for example, Topperr 3104 or Bork K700They contain active carbon and ion filter). neutralizes odors at the molecular level. They are more expensive than folk remedies, but last up to 6 months.
What NOT to do: 5 dangerous mistakes
Some “tips” from the Internet may not only not help, but also ruin the refrigerator. Avoid these activities:
- 🚫 Use fragrances with a strong odor (for example, car air fresheners). They will mix with the plastic scent and create an even more toxic mixture.
- 🚫 Wash the refrigerator with bleach or Domestos. Chlorine corrodes plastic and seals, and its vapors are dangerous to health.
- 🚫 Close the refrigerator tightly to “ventilate”. Without air circulation, the smell will only intensify.
- 🚫 Place open containers with ammonia in the refrigerator. It can damage display (in models with electronic control) and leave a persistent chemical odor.
- 🚫 Use acetone or solvents for cleaning. They dissolve the plastic and spoil the coating.
Also, do not turn on the refrigerator at maximum cooling mode in the first days - this will increase the release of volatile compounds from the plastic. Optimal temperature for “breaking in”: +5°C in the refrigerator and -12°C in the freezer.
How to speed up the removal of odor: life hacks
If you need to urgently get rid of the odor (for example, before loading food), use these techniques:
- 💨 Fan opposite the open door. Direct the air flow inside the refrigerator for 2-3 hours - this will speed up the evaporation of volatile compounds.
- ☀️ Ultraviolet lamp. 15-20 minutes of irradiation kills bacteria that increase the odor. Suitable for models without LED backlight.
- ❄️ "Shock freezing". Set the refrigerator to minimum temperature (-24°C) for 1 hour, then turn it off for 2 hours. A sharp drop destroys the odor molecules.
For models with No Frost system (for example, LG GA-B489YGQZ) the "defrost mode" is effective: turn off the power, leave the door open and point at evaporator warm air from a hairdryer (no closer than 30 cm!). This will remove the deposits that hold the odor.
Why can't you use scented candles?
Candles emit soot, which settles on the seal and ventilation grilles. This not only does not remove the smell, but can also cause damage to temperature sensor (in models with electronic control).
When the smell is a sign of malfunction
If after 2-3 weeks of active use the smell has not disappeared or has become similar to fumes, rotten eggs or acetone, this may indicate:
- 🔥 Compressor overheating (often in models Indesit DF 4180 W if installed incorrectly).
- ⚡ Breakdown of wiring insulation (smell of burning plastic).
- 🦠 Bacterial proliferation in the drainage system (smell of hydrogen sulfide).
In such cases:
- Unplug the refrigerator.
- Check the back wall for melting.
- If the smell comes from the freezer, defrost it and inspect evaporator for ice and rust.
- Contact the service center (under warranty, such repairs are free).
⚠️ Attention: If a burning smell is accompanied crackling or sparking, immediately unplug the plug from the socket and do not turn on the refrigerator until the technician arrives! This is a sign of a short circuit.
FAQ: Frequently asked questions about the smell in a new refrigerator
How long should you ventilate the refrigerator before turning it on for the first time?
Minimum 12 hours with an open door in a ventilated area. For models with No Frost (for example, Bosch KGE39AW2AR) it is better to wait 24 hours - they have more plastic parts.
Is it possible to use a refrigerator if it smells like plastic?
Yes, but Do not store food in it for the first 3–5 days. The smell is not toxic in small concentrations, but can be transferred to food (especially cheese, butter, bread). If the aroma is very strong, use absorbers (charcoal, soda).
Does defrosting help remove the smell?
Yes, but only if the reason is not plastic, but stagnant water in the drainage system. For new refrigerators, defrosting is ineffective. It is better to combine it with treatment with vinegar or citric acid.
Which models of refrigerators smell the least?
The equipment with the least smell is antibacterial coating (for example, Panasonic NR-BN30AW1) and glass shelves (Samsung RB37A52N0SA). It is also worth choosing models with carbon filter an air circulation system.
What to do if the smell returns after treatment?
This means that the source of the odor has not been eliminated. Check:
- Door seal for cracks.
- Drain hole for blockage.
- Back wall for melting.
If everything is in order, repeat the treatment ozonizer or vinegar.
