Buying a new refrigerator is always a joyful event, promising freshness of food and ease of storage. However, the joy is often overshadowed by an obsessive chemical aroma that emanates from the interior walls, shelves and drawers. This peculiar odor, often referred to as “new smell,” is caused by volatile organic compounds emitted by plastic parts and rubber seals during the manufacturing and packaging processes.
This problem cannot be ignored, as foreign aromas can be absorbed into foods, especially dairy products, butter and open drinks, changing their taste. In addition, prolonged inhalation of styrene or phenol vapors, which may be contained in low-quality plastic, is undesirable for health. Therefore elimination of odor becomes a priority before the first load of products.
In this article we will analyze time-tested and practice-tested methods that will help you neutralize chemical aroma. You will learn which absorbents work best, how to properly carry out the initial wash and why it is important not to rush to connect the equipment to the power supply immediately after unpacking.
Reasons for the appearance of a persistent chemical odor
The main source of the unpleasant odor is the polymer materials from which the internal elements of the chamber are made. During production, various types of plastic, foam and rubber are used, which accumulate volatile substances in the closed space of the container. Even if the refrigerator had been in the warehouse for months, the sealed packaging prevented these substances from evaporating.
The intensity of the odor directly depends on the quality of the materials and the ambient temperature. In a hot room, the process of evaporation of chemical compounds occurs faster and more intensely. This is why new modelss delivered in the summer often smell stronger. It is important to understand that completely inert materials practically do not exist in the mass production of household appliances.
There is also a risk of manufacturing defects when low-grade plastic with a high content of harmful impurities was used. In such cases, the smell can be not just unpleasant, but pungent and pungent. If after all the cleaning procedures the aroma does not disappear within two weeks, this is a reason to contact a service center to check the quality of the components.
⚠️ Attention: If the smell of plastic is accompanied by the smell of burnt wiring or rubber after the first turn on, immediately unplug the device and call a technician. This may indicate a malfunction of the compressor or electrical part.
It is also worth considering that some manufacturers use special antibacterial coatings or impregnations for seals, which have their own aroma, distinguishable from simple plastic. It is usually less intrusive and disappears on its own within a few days of active use.
Primary preparation and wet cleaning
The first and most important step is a thorough wet treatment of all internal surfaces. Simply wiping the dust with a dry cloth will not be enough, since it is necessary to wash off the thin film of factory grease and preservatives that are often applied to plastic to protect it during transportation.
First, you need to remove all removable elements: shelves, drawers, egg trays and containers on the door. It is best to wash them separately in the bath or shower using warm water and a mild detergent. Do not use abrasive sponges, as micro-scratches on the plastic will accumulate dirt and odors in the future.
☑️ Primary treatment of the refrigerator
Wash the main chamber carefully, trying not to fill the ventilation holes and the No Frost system with water, if it is provided for in the design. An ideal solution for cleaning is baking soda or a weak vinegar solution, which not only cleans, but also begins the process of neutralizing odors. After washing, thoroughly wipe all surfaces dry.
Pay special attention to the rubber seal on the door. Industrial dust and technical liquids often accumulate in its folds. Wipe the seal with a cotton pad soaked in lemon juice or a weak solution of vinegar to remove sticky residue.
Effective folk remedies-absorbents
After the refrigerator is washed and dried, the stage of using absorbents begins. These substances are capable of absorbing molecules of odorous gases from the air circulating inside the chamber. Folk wisdom offers many options, and many of them are really effective due to their physico-chemical properties.
One of the most accessible means is activated carbon. This is a classic adsorbent with a porous structure that perfectly retains organic molecules. It is enough to crush 10-15 tablets of ordinary pharmaceutical charcoal, put them in small containers and place them on the shelves of the refrigerator. This “tablet” needs to be changed every few days.
Other popular products that can be found in any kitchen:
- 🍞 Black bread - cut several slices of black rye bread and place them on saucers throughout the chamber; bread perfectly absorbs extraneous aromas.
- 🍚 Rice or oatmeal - raw cereal, poured into an open container, works as a natural filter, absorbing moisture and odors.
- ☕ Ground coffee - freshly ground coffee has a powerful aroma that can overpower the smell of plastic, but use this method with caution so that the refrigerator itself did not smell like a coffee shop.
- 🧂 Salt or soda - an open pack of baking soda or a bowl of coarse soda are inexpensive and effective absorbers.
They themselves can become a source of unpleasant odor or mold if they are not replaced in time. The optimal period of use is 2-3 days, after which the product must be disposed of.
Use of specialized tools and equipment
If traditional methods do not seem effective enough to you or you prefer modern solutions, the market offers many specialized products for eliminating odors. They were developed by the chemical industry specifically to combat volatile organic compounds in household conditions.
In hardware stores you can find spray neutralizers that do not mask the odor, but break down the molecules of odorous substances. Also popular are gel odor absorbers that work gradually over several months. They often contain silver ions or other antibacterial components.
Deserve special attention ozonators. These are small devices that generate ozone, which oxidizes organic pollutants and kills bacteria. Using an ozonizer is one of the fastest ways to get rid of the smell of plastic, but requires compliance with safety precautions.
| Type of product | Principle of action | Validity period | Features |
|---|---|---|---|
| Carbon filter | Adsorption by pores | up to 3 months | Requires replacement, does not mask odor |
| Gel absorber | Chemical binding | up to 4 months | Safe, often has a fragrance |
| Ozonator | Ozone oxidation | Device operating time | Effective, but requires the absence of people and animals |
| Spray neutralizer | Splitting of molecules | Instantly | Requires re-processing over time |
⚠️ Attention: When using chemical sprays or ozonizer, be sure to remove all products. After treatment, the chamber must be thoroughly ventilated so that any remaining product does not get into the food.
Some modern refrigerator models are already equipped with built-in deodorization systems, for example, activated carbon filters or air ionizers. Check the instructions for your model Samsung, LG or BoschPerhaps you just need to activate this function or replace the standard filter that may have stagnated in the warehouse.
Ventilation and temperature conditions
The simplest, free and often underestimated way to combat the smell of plastic is time and draft. Volatile substances evaporate faster when air moves. After purchasing and unpacking, the refrigerator should be left turned off with the doors open for at least 24 hours, and preferably for 2-3 days.
If possible, place the refrigerator in a well-ventilated area or even on a glazed balcony (if the ambient temperature allows, but not lower than +5°C for most models). Direct sunlight should be excluded, since ultraviolet can damage plastic and rubber parts.
After the initial After ventilating and turning on the refrigerator, you should not immediately load it with food to capacity. Let the equipment run idle for at least a few hours. The circulation of cold air inside the No Frost system will help quickly remove residual volatile substances through the ventilation system.
It is important to observe the temperature regime when ventilating. If you place the refrigerator on the balcony in winter, make sure that the temperature does not fall below the permissible temperature for compressor oil (usually +5°C). Sharp cooling of the plastic can also temporarily change the nature of the odor, but will not eliminate it completely.
What you should absolutely not do
In an effort to quickly get rid of an unpleasant odor, owners of new equipment sometimes make mistakes that can lead to damage to the refrigerator. There are a number of actions that are contraindicated when caring for internal plastic surfaces.
Never use aggressive solvents such as acetone, gasoline or pure chlorine bleaches. They can react with the plastic, destroy its structure or make it more porous, causing the odor to be absorbed even deeper and become irreducible.
It is also not recommended to use steam cleaners to treat the internal chambers of a new refrigerator. The high temperature of the steam can deform the thin plastic of the shelves and disrupt the geometry of the seals, which will lead to loss of tightness in the future.
Why can’t you rub plastic with hard brushes?
Hard brushes leave microscopic grooves on the surface of the plastic. These grooves become filled with dust, bacteria and food particles, which over time begin to rot and emit their own unpleasant odor, which will be much more difficult to remove than the factory scent of plastic.
Do not try to “mask” the smell of plastic with strong fragrances, perfumes or air fresheners sprayed directly into the chamber. The mixture of chemical smell and perfume can become even more nauseating, and the products become saturated with this cocktail of aromas.
When to worry and contact service
In most cases, the smell of plastic is a temporary phenomenon that goes away on its own within 1-2 weeks of use. However, there are situations when a persistent chemical odor indicates problems with the quality of the product or its assembly.
If the odor does not disappear after a month, intensifies when the compressor is running, or has a burnt rubber tint, this may indicate overheating of the wire insulation or engine malfunction. In such cases, operating the device can be dangerous.
Also a reason to contact service is a situation where the smell comes not from plastic, but from freon or oil. Although modern refrigerants are often odorless, an oil leak from a compressor can produce a specific technical aroma that is absorbed into the products.
When purchasing equipment in large chain stores, you have the right to return the product in proper condition. quality within 14 days if you don't like it. However, if the refrigerator was in use, it will be necessary to prove that the smell is a manufacturing defect through an examination. Therefore, checking equipment for the absence of odors is important at the time of delivery, before signing the documents.
FAQ: Frequently asked questions
How long does it normally take for the smell from a new refrigerator to disappear?
Usually the smell disappears on its own within 3-7 days of active ventilation and operation. In some cases, especially when using a large amount of foam in packaging or low room temperatures, the process can take up to 2-3 weeks.
Can vinegar be used to clean a refrigerator?
Yes, a weak solution of table vinegar (9%) with water in a ratio of 1:3 is excellent for washing the internal chambers. It disinfects surfaces and helps neutralize chemical odors. The main thing is to thoroughly wipe all surfaces with clean water after treatment.
Does the material of the shelves affect the intensity of the smell?
Yes, glass shelves have virtually no odor, while plastic lattice shelves and drawers made of transparent plastic can smell stronger. Removable plastic elements can be taken to the balcony for ventilation separately from the refrigerator body.
Will turning on the refrigerator help remove the smell faster?
Turning on itself will not remove the smell, since at low temperatures the evaporation of substances slows down. However, a working ventilation system (in No Frost models) will circulate air through the filters, which, in combination with absorbents, will speed up the cleaning process.
Is it safe to store food while there is a slight smell?
It is possible to store food in a hermetically sealed container. It is better not to put open foods, especially fats, dairy products and baked goods, inside until the smell completely disappears, as they quickly absorb extraneous aromas.
