Plastic smell in the refrigerator: causes and 12 proven methods of getting rid of it

A new refrigerator is a joy for housewives, but it is often overshadowed by the persistent chemical aroma of plastic, which penetrates into the food and spoils the appetite. This smell appears due to emission of volatile organic compounds (VOC) from polymer materials, which is especially intense in the first weeks of operation. Even after thorough washing, an unpleasant “chemical” odor can persist for months if no action is taken.

In this article we will analyze reasons for the appearance of odor, compare the effectiveness of folk and professional methods for eliminating it, and also give step-by-step instructions for different types of refrigerators (No Frost, drip, with system Total No Frost). We will pay special attention to safety: what products cannot be used so as not to damage the seals and coating of the chamber.

Spoiler: the fastest way is a combination activated carbon and ozonizer, but it is not suitable for everyone. But a soda solution with citric acid works in 95% of cases within 12 hours. Read on to choose the optimal method for your model.

Why a new refrigerator smells like plastic: 3 scientific reasons

The smell does not appear just like that - it is the result of chemical processes in the materials. Here are the main culprits:

• 🧪 Emission of styrene and formaldehyde. Most refrigerator interior panels are made from ABS plastic (acrylonitrile butadiene styrene), which slowly evaporates monomers at room temperature. This is especially noticeable in models Indesit, Atlant and budget LG with thin walls.
• 🔥 Residual production products. When molding plastic parts, lubricants, antistatic agents and dyes are used, which are not always completely removed at the factory. For example, in refrigerators Samsung RB** there is often a smell of “burnt” plastic due to process oils.
• ☀️ Reaction to heat and moisture. When first turned on, the compressor heats the rear wall, accelerating the evaporation of the BOC. In systems No Frost the process is aggravated by air circulation - the smell spreads faster.

Interesting fact: in European Union there is a norm EN 71-9limiting the release of harmful substances from household plastics technology. But in budget models (especially those made in Asia), these standards are often violated. If the smell is pungent and causes a headache, this is a reason to check the safety certificates with the seller.

⚠️ Attention: If the plastic smell is accompanied metallic taste or resembles “burning”, immediately turn off the refrigerator and check the serviceability of the compressor. This could be a sign of overheating or a refrigerant leak (especially in models with inverter compressor).

Preparation of the refrigerator: what to do BEFORE turning it on for the first time

Many skip this stage, but in vain: proper preparation reduces the time for the odor to disappear from 2-3 weeks up to 2-3 days. Follow this algorithm: Remove all protective films, remove shelves and containers. Place them in a well-ventilated area (balcony, street) for 6-12 hours. In models with

1. Unpack and ventilate. Use a warm solution of baking soda (2 tablespoons per 1 liter of water) or specialized products like. Remove all protective films, remove shelves and containers. Place them in a well-ventilated area (balcony, street) for 6-12 hours. In models Liebeherr With BioFresh-zones, be sure to remove the door seals. - they often smell the strongest.
2. Rinse all surfaces. Use a warm solution of baking soda (2 tablespoons per 1 liter of water) or specialized products such as Topperr 3101. Avoid chlorine-containing cleaners - they react with plastic and increase the smell.
3. Wipe with vinegar solution. Mix water and 9% vinegar in a 3:1 ratio, wipe the inner walls. Vinegar neutralizes up to 70% of volatile compounds. For refrigerators with ionic silver (for example Panasonic NR-B**) vinegar is replaced with citric acid (1 tsp. 0.5 l of water).

Important: do not turn on the refrigerator immediately after washing. Let it dry for 2-3 hours with the door open. data-i="98">(for example, electronically controlled (For example, Bosch KGE36**) before the first start, reset the settings through the menu Settings → Factory Reset - this will eliminate possible sensor errors that can increase the odor.

Top 6 folk remedies: what really works

Folk methods are good because they are accessible, but their effectiveness varies depending on the material of the refrigerator. We tested 12. methods and selected the best:

Life hack for systems No Frost: put the activated coal in ventilation holes (usually located on the back wall). This will speed up the cleaning of the circulating air. In refrigerators Samsung coal is placed in both compartments - for the freezer and refrigerator compartments. Twin Cooling Plus Coal is placed in both compartments - for the freezer and refrigerator compartments.

Professional odor absorbers: when traditional methods do not help

If the smell of plastic persists for more than a month or is accompanied by irritation of the mucous membranes, it’s time to move on to “heavy” artillery". Professional products are divided into 3 types:

• 🧬 Ion exchange absorbers (for example, AirComfort AC-318). They work on the principle of binding odor molecules at the ionic level. Effective for refrigerators with antibacterial coating (series Hisense Multi-Air Flow). Cost: from 800 ₽.
• 🌬️ Ozonizers (OzonBox Mini). They generate ozone, which oxidizes organic compounds. Suitable for empty refrigerators (products are removed!). Processing time: 30-60 minutes. Important: after ozonation, ventilate the chamber for 2-3 hours.
• 🧴 Helium neutralizers (SmellOff, OdorGone). Contains cyclodextrins - molecules that “capture” odors. One bottle (50 ml) is enough for 3-4 treatments. Particularly effective for refrigerators with plasma air purification (for example, Sharp SJ-X**).

For models with inverter compressor (for example, LG GA-B489) we recommend combining an ozonizer with a gel neutralizer: the first will eliminate the main odor, the second will consolidate the result. Cost of the set: ~2500 ₽, but the effect lasts up to 6 months.

⚠️ Attention: Do not use aromatic fresheners (type Air Wick) in the refrigerator! They mask the odor but do not eliminate the cause, and essential oils can react with the plastic and enhance the “chemical” odor. The exception is specialized refrigerator fresheners based on activated carbon (for example, Fridge Fresh).

What NOT to do: 5 dangerous mistakes

Some "tips" from the Internet can irreversibly damage the refrigerator. Here is what is strictly prohibited:

• 🔥 Use bleach or Domestos. Chlorine destroys door seals and leaves toxic fumes that are absorbed into the plastic. Beko this can lead to corrosion. evaporator. NeoFrost this may lead to corrosion of the evaporator.
• 🧴 Apply essential oils to the walls. Oils (especially citrus fruits) corrode ABS plastic, leaving sticky stains in models with with an antibacterial coating (for example, Haier) layer.
• ❄️ Freeze plastic. Some “experts” advise turning the refrigerator on to maximum cold to “seal in” the smell. In fact, this increases the release of BOC during subsequent thawing.
• 🧽 Clean with abrasive sponges. Metal sponges or hard brushes scratch the surface, creating microcracks in which odors accumulate. In refrigerators with mirror coating (series Gorenje NRK**this leads to clouding walls.
• 🔌 Disconnect the refrigerator for a long time. timeWhen turned off without ventilation, the smell is concentrated. Exception - treatment with an ozonizer (but not longer than 1 hour!).

If you have already made one of these mistakes, do not panic. In most cases, deep cleaning with a steam generator (for example, Karcher SC 1) followed by treatment with a gel neutralizer will help. data-i="192">) before cleaning, turn off the power and cover the electronic unit with film. display (For example, Samsung Family Hub) Before cleaning, turn off the power and cover the electronic unit with film.

What to do if the smell of plastic appears in an old refrigerator?

If there is a plastic smell occurred in a refrigerator older than 5 years, the reason may lie in:

1) Decomposition of the seal on the shelves due to overheating of the compressor. thermostat and ventilation. —over time, the rubber releases sulfur compounds. Solution: replacing the seal (cost ~1500 rubles).

2) Melting of plastic fasteners shelves due to compressor overheating. Solution: Check the thermostat and ventilation.

3) Reactions of plastic with new detergents. Solution: washing with distilled water.

In any case, such a smell is a reason for diagnosis in a service center, especially if refrigerator atmospheric type (for example, ZIL or "Minsk").

Step-by-step instructions for refrigerators with No Frost

Systems No Frost require a special approach due to forced air circulation, which distributes the smell to all corners Follow this algorithm:

1. Disconnect the refrigerator and remove all products. In models with double compressor (for example, ATLANT XM 6025-031) turn off both circuits through the menu Cool Select → Off.
2. Remove the back panel (if there is access to the evaporator). In refrigerators Indesit it is attached to 4 latches. Wipe the evaporator with a solution of citric acid (1 tablespoon per 1 liter of water).
3. Treat the ventilation ducts with. Use OdorGone spray or hydrogen peroxide solution (3%). data-i="222">The channels are located on the sides - they are cleaned with cotton swabs. Electrolux With AirFlow The channels are located on the sides - they are cleaned with cotton swabs.
4. Rinse the drainage hole. In the system No Frost it often becomes clogged, which increases odors. Use pipe cleaner (sold in pet stores) and a soda solution.
5. Install the absorber into the ventilation area. data-i="231">is suitable No Frost will do carbon filter FridgeFresh FF-01 (attached with magnets).
6. Turn on the "Vacation" mode (if available). data-i="236">it is activated through Liebeherr it is activated via Menu → Holiday Mode. This will reduce air circulation and speed up odor neutralization.

For refrigerators with Low Frost (for example, Bosch KGV36VW23R) steps 2-3 can be skipped - they do not have forced ventilation, so standard cleaning is sufficient.

How to prevent the return of the smell: prevention

To prevent the plastic smell from returning, follow these rules:

• 📅 Change absorber every 3 months. Even if there is no smell, carbon filters become saturated and stop working. data-i="248">ionic silver ionic silver (For example, Panasonic NR-B**) it is enough to do this once every six months.
• 🧼 Wash the refrigerator once a month with a vinegar solution or a specialized product (Topperr 3101For models with antibacterial coating use soft microfiber napkins.
• 🍎 Store products in containers. Opened fruits, cheeses and sausages absorb plastic odors in refrigerators. Samsung s Metal Cooling it also prevents oxidation of metal surfaces.
• 🌡️ Control the temperature. Optimal mode: +4°C in the refrigerator compartment i -18°C in the freezer. data-i="262">set electronic control configure Super Cool for the first 24 hours after loading the products.

For refrigerators with freshness zones (for example, Liebeherr BioFresh) we additionally recommend:

• Wipe once a week sealants glycerin - this prevents them from cracking and odors.
• Use special napkins for freshness zones (for example, Fridge Fresh), which neutralize ethylene released fruits.

FAQ: Frequently asked questions about the smell of plastic in the refrigerator

How long does it take for the smell of plastic to disappear on its own?

Depending on the model and material:

• Budget refrigerators (ABS plastic): 3-6 weeks with regular ventilation.
• Middle segment (plastic with antibacterial coating): 1-2 weeks.
• Premium models (for example, Liebeherr with BioFresh): 3-5 days.

It will help speed up the process combination of activated carbon and soda (see efficiency table above).

Is it possible to use a refrigerator if it smells like plastic?

Yes, but with reservations:

• If the smell weak does not cause irritation - you can store food in airtight containers.
• If the odor cutting or similar to "burning" - cannotThis may be a sign of a refrigerant leak (especially in models with isobutane R600a).
• For baby food and medications, it is better to wait for the odor to completely disappear (7-10 days).

Does the ozonator help with plastic odor?

Yes, but with nuances:

• Efficiency: eliminates 90-95% of the odor in 1 treatment (30-60 minutes).
• Limitations:
  • Cannot be used in refrigerators with rubber seals older than 5 years - ozone accelerates their destruction.
  • After treatment, you need to ventilate the chamber at least 3 hours.
  • Not suitable for models with plasma air purification (for example, Sharp SJ-X**) - it can damage the ionizer.
• Alternative: for sensitive models use UV lamps (for example, Philips UV-C), but their efficiency is lower (70-80%).

Why did the smell of plastic intensify after cleaning with vinegar?

This is a typical reaction of ABS plastic to acids. Reasons:

• Vinegar dissolves the top layer of plastic, releasing additional monomers.
• In refrigerators with antibacterial coating vinegar destroys the silver layer, which enhances the smell.
• If there was vinegar undilutedit could react with the remainder of the factory lubricant.

What do:

1. Immediately rinse the refrigerator distilled water.
2. Wipe the walls with a solution baking soda (1 tbsp per 1 liter of water).
3. Place in the chamber cyclodextrin-based absorber (for example, OdorGone) for 24 hours.

How to remove the smell of plastic in the freezer?

The freezer requires a special approach due to low temperatures:

1. Defrost the camera (even if it is No Frost). In models with manual defrost (for example, ATLANT MXM 170-03) this will take 6-8 hours.
2. Treat the walls with solution hydrogen peroxide (3%) —it is effective at low temperatures.
3. Use an absorber, designed for frost:
   • Coal tablets (for example, FridgeFresh) - work down to -30°C.
   • Gel absorbers (for example, SmellOff Arctic) - up to -25°C.

Do not turn on the camera immediately - let the absorber work for 12-24 hours at room temperature.

For freezers with quick freezing system (for example, Samsung RZ32M7120) after processing, turn on the mode Power Freeze for 2 hours - this will “seal” the neutralized odor molecules in the ice.
