The situation when after purchase or defrosting An obsessive chemical aroma appears in the refrigerator compartment, familiar to many. Most often, the source of trouble is the polymer base of the internal shelves or insulating materials. This is a natural process for new technology, but it requires intervention so that the products are not saturated with foreign odors.
The first thing that needs to be done is to thoroughly in primary washing all surfaces. Many users ignore this stage, relying on factory cleanliness, which is a serious mistake. Preservatives used during transportation and residues from production processes when heated give a persistent odor.
Do not panic if the aroma persists for several days. In most cases, the problem is solved by ventilation and the use of simple absorbents. The main thing is not to load the chamber with products until the “chemistry” has completely disappeared.
Causes of the appearance of a chemical smell
The main culprit is polystyrene other types of plastic from which the internal drawers and shelves are made. During production, many components are used that, upon contact with air or when the compressor is turned on for the first time, begin to actively evaporate volatile substances. This is especially noticeable in models of the budget segment.
The second reason may be overheating. If capacitor (the grill at the back) touches the wall or furniture, the temperature inside the case increases. The plastic begins to “phon” more than usual. The smell may also come from new wiring or motor insulation during the first hours of operation.
⚠️ Attention: If the smell of plastic is accompanied by smoke or a burning smell, immediately unplug the device. This may indicate a short circuit or overheating of the electric motor.
Sometimes the source is not the refrigerator itself, but the packaging. Cardboard, Styrofoam and tape left inside when first started will emit a pungent aroma when heated. Always check the camera for the presence of shipping materials before turning it on. It is worth noting that some models may have a more pronounced odor due to the characteristics of the raw materials used. This is not a defect, but a technological feature that requires time to air out.
It is worth noting that some models Indesit or Atlant may have a more pronounced odor due to the characteristics of the raw materials used. This is not a defect, but a technological feature that requires time to weather.
Express methods for eliminating odor
The fastest method is mechanical cleaning using an acidic environment. A solution of citric acid or vinegar perfectly neutralizes the alkaline components of plastic. You will need warm water and any of these products in a ratio of 1 tablespoon per liter.
Wipe all surfaces thoroughly, paying special attention to corners and joints. Don't forget to remove all removable elements - shelves, drawers, egg containers. It is better to wash them separately in the bathroom or under the tap.
- 🍋 Citric acid solution is a mild remedy for delicate plastic.
- 🧼 Laundry soap - effectively removes grease film and preservatives.
- 🌿 Chamomile decoction is a natural antiseptic with a pleasant aroma.
After wet cleaning, be sure to wipe the surfaces dry with a clean rag. The remaining moisture can increase the growth of bacteria, which will also add mustiness to the smell of plastic.
Folk remedies for absorbing aroma
If simple washing does not help, absorbents come into play. These substances have a porous structure that draws odor molecules from the air. Place the selected sorbent on the shelves and leave the refrigerator open or turned off for several hours.
One of the most effective means is activated carbon. It is enough to crumble 10-15 tablets and scatter them on saucers. Charcoal works as a professional filter, purifying the air from volatile compounds.

| Method | Method of application | Action time |
|---|---|---|
| Activated carbon | Crumble into plates | 24-48 hours |
| Baking soda | Open can | 3-4 days |
| Coffee beans | Spread over the surface | 2-3 days |
| Silica gel | Until the smell disappears |
Soda has also worked well. An open pack left on the top shelf will gradually absorb all foreign odors. You need to change the soda every three days until the result is complete.
Professional chemistry and ozonation
When traditional methods are powerless, you have to resort to “heavy artillery”. Specialized sprays for removing odors from cars or household appliances contain enzymes that break down odor molecules. They are more effective than simple flavors.
Ozonation is a powerful method that is often used by service centers. Ozone is a strong oxidizing agent and destroys any organic and inorganic odors. You can use a household one ozonator, leaving it inside a closed chamber for 20-30 minutes.
⚠️ Attention: Ozone is toxic to humans in high concentrations. During the procedure, there should be no people or animals in the room, and after treatment, the chamber must be thoroughly ventilated.
It is important not to confuse odor removal with masking it. Using air fresheners or strong-smelling detergents will only temporarily hide the problem by mixing the smell of plastic with a chemical fragrance.
☑️ Algorithm for dealing with odor
How long does it take for the smell to disappear
The time required for the aroma to completely disappear depends on the quality of the plastic and operating conditions. On average, a new refrigerator stops smelling after 3-7 days of active use. If the equipment Liebherr or Bosch, the process can go faster thanks to high-quality materials.
Frequent opening of the door and through ventilation of the room helps speed up the process. If you leave the refrigerator turned off with the door open for 2-3 days, the smell will go away almost completely.
There is a misconception that the smell should go away on its own after a month. This is wrong. If the situation has not changed after a week of intensive ventilation and washing, perhaps the problem is deeper than just the surface layer of plastic.
Why does the smell return after defrosting?
When defrosting, the ice melts and water can penetrate microcracks in the plastic or insulation. With subsequent freezing and heating, preserved odors come to the surface again. Repeated deep drying and treatment with absorbents is required.
When to worry: dangerous symptoms
There is a fine line between the smell of new plastic and the smell of scorched insulation. If the odor resembles burnt rubber or burnt wiring, this is a sign of a malfunction. This often happens when the network is overloaded or there is a malfunction start relay.
Also, the appearance of a smell along with a hum or vibration that was not there before should alert you. In this case, you need to call a technician to diagnose the electrical part. Self-repair in such a situation is dangerous.
Pay attention to the condition of the sealing gum. Cheap rubber, when aging or exposed to detergents, can emit a specific “rubber” smell, which can easily be confused with the plastic of the body.
Prevention of odors
In order not to encounter a similar problem in the future, you should follow the operating rules. Do not place hot products in the chamber - a sharp temperature change provokes the release of volatile substances from the plastic shelves.
Clean your refrigerator regularly using mild, non-abrasive products. Aggressive chemistry can damage the protective layer of plastic, making it porous and susceptible to odors.
- 🧊 Do not store food without packaging - fats and juices are absorbed into the plastic.
- 🌬️ Once a month, ventilate the chamber, leaving the door open for 15 minutes.
- 🧽 Use special wipes for household appliances to wipe the shelves.
Following these simple recommendations will extend the life of your appliances and maintain food freshness. Remember that proper care of the refrigerator is the key to the health of the whole family.
Is it possible to use bleach to remove odors?
The use of chlorine-containing products (for example, “Whiteness”) is highly not recommended. Chlorine can react with plastic, changing its color and texture, and leaving a lingering odor that is difficult to remove. In addition, chlorine vapor can get on food.
Will an ozonizer help remove odor forever?
An ozonizer effectively removes odor, but not always forever. If the source of the odor is the plastic material itself, which continues to release substances, the odor may return. It is better to use an ozonizer as a finishing treatment after washing and airing.
What to do if an odor appears in an old refrigerator?
The sudden appearance of a plastic smell in old appliances is an alarming sign. This may indicate melted wiring, overheating of the compressor, or deterioration of insulating materials. It is urgent to check the technical condition of the device.
