The smell of plastic in the refrigerator: why it appears and how to eliminate it forever

A new refrigerator is always a joy, but it is often overshadowed by the persistent chemical smell of plastic, which can last for weeks. Even if the equipment is not new, an unpleasant “aroma” may appear after defrosting, cleaning or replacing internal parts. Unlike the smell of spoiled food, the plastic “smell” does not disappear by itself - it needs to be removed purposefully.

In this article we will analyze causes of odor, tell you what materials manufacturers use (and why some refrigerators smell stronger than others), and also give step-by-step instructions how to eliminate the problem - from folk methods to professional remedies. You'll learn what to do if the odor returns and how to prevent it from happening in the future.

Important: Some methods can damage the interior lining of the refrigerator if used incorrectly. We will note critical nuanceswhich you should pay attention to in order not to spoil the equipment.

Why a new refrigerator smells like plastic: 5 main reasons

The smell of plastic in a refrigerator is not a defect, but a consequence of technological processes. Even premium models from Liebherr or Samsung can emit a chemical aroma in the first days after purchase. Here are the main reasons:

• 🔹 Emission of volatile organic compounds (VOCs). New polymer parts (shelves, containers, seals) contain residual substances from production that evaporate at room temperature. This is especially noticeable in refrigerators with ABS plastic - it is cheaper, but less stable.
• 🔹 Heating during transportation. If the refrigerator was stored in a warehouse without ventilation or transported in hot weather, the plastic “sweats” and begins to smell stronger.
• 🔹 Low quality materials. Budget models (for example Indesit or Beko the basic line) are often equipped with plastic with a high styrene content - it takes longer to weather.
• 🔹 Remains of packaging materials. Polystyrene foam, film or cardboard in contact with internal surfaces can impregnate them with odor.
• 🔹 Reaction to detergents. If aggressive chemicals (for example, chlorine-containing ones) were used during the first wash, they react with the plastic and increase the odor.

Interesting fact: refrigerators with a system No Frost may smell stronger due to forced air circulation, which “spreads” volatile compounds throughout compartments In models with drip defrosting, the smell is often localized only in the freezer compartment.

⚠️ Attention: If the smell of plastic is accompanied burnt or pungent chemical aroma, this may indicate overheating of the compressor or damage to the insulation. In this case, immediately disconnect the refrigerator from the network and contact the service center.

How long does it take for the smell of plastic to disappear: norms and deviations

In most cases, the smell of plastic in a new refrigerator disappears on its own after 3–7 days with proper use. However, there are nuances:

If the smell does not disappear longer 2 weeks, this is a reason to think about defect of materials or violation of the rules of operation. For example, some users leave packaging film on the shelves, which blocks weathering.

Tip: To speed up the process, leave the refrigerator open. 1–2 hours a day (unplugged!). This will help ventilate the chambers. But do not forget that leaving the door open for a long time can lead to the formation of condensation on the seal.

How to get rid of plastic smell: 10 working methods

If you don’t have time or patience to wait until the smell disappears on its own, use these methods. We have divided them into folk (available and cheap) and professional (more). effective, but expensive). To enhance the effect, you can wipe the walls with juice.

Folk remedies (without chemicals)

• 🍋 Lemon or citrus peels. Cut the lemon in half and place the halves on each shelf for 12 to 24 hours. The acid neutralizes volatile compounds. To enhance the effect, you can wipe the walls with juice.
• ☕ Natural coffeePlace an open pack of ground coffee (or beans in gauze) in the refrigerator for a day. Coffee absorbs odors well, but can leave its aroma.
• 🧂 Soda or activated charcoal. Place a glass of soda on each shelf (2 tablespoons per 200 ml of water) or place charcoal tablets in gauze bags. Change every 12 hours.
• 🌿 Herbs and spices. the bag will help to eliminate the smell of plastic. The main thing is not to place them next to the food so as not to pick up the aroma.
• 🧊 Freezing with vinegar. Wipe all surfaces with a solution of vinegar (1:1 with water), then turn on the refrigerator at maximum cold for 2-3 hours. The vinegar will evaporate, taking some of it with it. odor.

Professional methods

• 🧴 Special odor absorbers. Products such as OdorGone or Fridge Fresh contain activated carbon and minerals that neutralize VOCs. after 6–8 hours.
• 💨 Air ozonizers. Devices like Xiaomi Mi Air Purifier with the ozonation function destroy odor molecules. 30-40 minutes of operation in an empty refrigerator is enough.
• 🧽 Detergents for refrigerators. Use specialized cleaners (for example, Topperr 3101 or Sano Fridge Cleaner). They not only remove the odor, but also form a protective film.
• 🔄 UV lamps. (for example, Philips TUV) destroy organic compounds that cause odor. Suitable for models with the function UV-Clean.
• 🛠️ Replacing plastic parts. In extreme cases, you can replace the shelves or containers with new ones (if the smell comes from them). data-i="148">Replacing plastic partsSamsung FlexZone).

Warning: Do not use bleach, ammonia or alcohol to clean the refrigerator - they can react with the plastic and increase the smell. Also avoid aromatic fresheners (such as Air Wick), as they only mask the problem, but do not solve it.

What to do if the smell of plastic returns

Sometimes it seems that the smell has disappeared, but after a few days it returns. This happens for three reasons:

1. Poor ventilation —the smell accumulates in hard-to-reach places (for example, behind the back wall or in the drainage hole).
2. Relapse from plastic parts —some polymers emit VOCs in waves, especially when the temperature changes.
3. Layering of new odors - if products with a strong aroma (fish, onions, spices) were stored in the refrigerator, they mixed with the plastic smell.

In such cases it will help deep cleaning:

1. Remove all removable elements (shelves, drawers, door pockets) and wash them in a solution of soda with the addition of hydrogen peroxide (1 tablespoon per 1 liter of water).
2. Clean the drainage hole (usually located on the back wall) using a cotton swab sticks soaked in vinegar.
3. Check the rubber seal - dirt often accumulates there, which increases the smell. Wipe it with a solution of ammonia (1 teaspoon per 1 liter of water).
4. Use ozonator or UV lamp to treat the empty refrigerator for 1-2 hours.

If the problem recurs regularly, this may indicate material defect. In this case, contact the service center - some manufacturers (for example, LG or Electrolux) replace parts under warranty if the smell does not disappear for more than a month.

⚠️ Attention: Do not try paint or varnish plastic parts of the refrigerator - this will disrupt their properties and can lead to cracks. Also, do not use abrasive sponges, which scratch the surface and create micropores where odors accumulate.

How to prevent the appearance of plastic odors in the future

It is better to take measures in advance than to deal with the consequences later. Here 5 rulesthat will help you avoid the problem:

• 📦 Remove all packaging immediately after purchase. Polystyrene foam, film and cardboard can imbue plastic with odor.
• 🧼 Rinse the refrigerator before first use. Use warm water with soda or a special product for refrigerators.
• 🌬️ Ventilate the refrigerator in the first days. Leave the door open for 10–15 minutes 2 times a day.
• 🍎 Do not store foods with a strong odor in the first weeks. Onions, garlic, fish and spices can be “absorbed” into the plastic.
• 🔧 Check the seal once a month. Dirt and moisture on the elastic accelerate the appearance of unpleasant odors.

If you buy used refrigerator, be sure to ask the seller to demonstrate its operation without products - this way you can assess whether there is a smell of plastic or mold. This is especially true for models older than 5 years, where low-quality polymers could be used.

Tip: When choosing a new refrigerator, give preference to models with antibacterial coating (for example, Samsung BioFresh or Panasonic Ag Clean). It not only prevents odors, but also slows down the growth of bacteria.

Why do some refrigerators smell stronger than others?

The strength of the smell depends on the type of plastic and production technology. For example, cheap models are often made from ABS plastic (acrylonitrile butadiene styrene), which contains styrene, a substance with a pungent chemical odor. Premium brands (Liebherr, Miele) use polypropylene or polycarbonate - they practically do not smell, but are more expensive to produce. The molding method also has an impact: injection molding produces less VOCs than extrusion.

What is the danger of plastic smell in the refrigerator: myths and reality

Many users are worried that the smell of plastic may be harmful to health. Let's figure out where the truth is and where the exaggeration is.

However, if you have asthma, allergies or hypersensitivity to chemical odorsit is better not to take risks and fix the problem as quickly as possible. In rare cases, VOCs can cause headaches or irritation of mucous membranes.

Interesting: The EU and the USA have strict regulations on the content of VOCs in household appliances (standard EN 71-9). Refrigerators certified to this standard emit minimal amounts of volatile substances. When purchasing, pay attention to the labeling Low VOC.

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

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

Yes, you can, but it is better to eliminate the smell before putting in food. If the refrigerator is new, the smell will disappear after a few days. If the equipment is used or the smell is very strong, clean it using one of the described methods. Food in sealed packaging (glass, vacuum) can be stored even if there is an odor.

Why does the smell of plastic increase during defrosting?

During defrosting, the temperature inside the refrigerator increases, which accelerates the evaporation of volatile organic compounds (VOCs) from the plastic. The odor may also increase due to condensation, which “pulls” chemicals out of the material. After defrosting, be sure to rinse the refrigerator with a soda solution and ventilate it.

Does laundry soap help against plastic odors?

Laundry soap is ineffective against plastic odors, since it is designed to remove grease and organic contaminants, not chemical fumes. Moreover, the soap itself can leave a specific smell. It is better to use soda, vinegar or specialized products.

Can the smell of plastic disappear on its own?

Yes, in most cases the smell of plastic in a new refrigerator disappears on its own through 3–14 days (depending on the model and materials). However, if the smell persists for more than a month, this may indicate a defect in the materials or improper operation (for example, storage in an unventilated area).

What to do if the smell of plastic is mixed with the smell of products?

In this case you need deep cleaning:

1. Remove all food and turn off the refrigerator.
2. Rinse all surfaces with a solution of vinegar (1:1 with water).
3. Wipe the sealing gum with ammonia (1 tsp per 1 liter water).
4. Place activated carbon or an ozonizer on the shelves for 12 hours.
5. Repeat the procedure if the smell remains.

If the problem persists, check the drainage hole - dirt often accumulates there.

If none of the methods helped, contact the service center - the refrigerator may use low-quality materials and parts will need to be replaced under warranty.
