The appearance of a new refrigerator in the house is always a joy, promising food freshness and the convenience of storing supplies. However, this euphoria is often overshadowed by a sharp, specific aroma that emanates from the internal surfaces of the chamber. The smell of new plastics, glues and lubricants can be so intense that it permeates even packaged foods, making them unfit for consumption. This problem cannot be ignored, since volatile chemical compounds can be toxic, and a persistent aroma will spoil the taste of any food.
In most cases, such an odor is a natural consequence of the production process. During assembly, various polymers, sealants and adhesives are used, which in the closed space of the container, upon first activation, begin to actively evaporate. Ventilation and time are your main allies, but more active intervention is often required to speed up the weathering process. It is important not to panic and act consistently, using proven methods of cleaning and neutralizing extraneous odors.
Before taking radical measures, it is necessary to understand the nature of the origin of the odor. If the equipment is new, then the interior plastic and polyurethane foam will smell. If the smell suddenly appears on an old unit, this may indicate overheating of components or spoilage of food in hard-to-reach places. In this article we will focus specifically on eliminating the odor of new equipment, since this is the most common request from users who have just purchased a household appliance.
Causes of a specific odor
The main source of unpleasant odor is polymer materials from which the internal walls, shelves and drawers are made. During the manufacturing process, various additives are used to give the plastic flexibility, strength and color. When heated or simply during initial use, these substances begin to release volatile organic compounds. The smell may also come from the technical lubricant of the compressor if it gets on the internal elements, or from the glue used to fix the seals.
Another reason may be improper transportation. If the refrigerator was transported in a lying position, oil from the compressor could get into the refrigerant circulation system or onto the internal walls of the chamber. When first turned on, this oil heats up and gives off a strong chemical smell. In addition, the original packaging, especially if it was not removed immediately or partially, could transfer its aroma to the surfaces.
⚠️ Attention: If the smell resembles scorched rubber or burnt plastic and is accompanied by a humming or sparking sound, immediately unplug the device. This may indicate a faulty electrical wiring or overheating of the engine, which requires specialist intervention.
Do not forget about the hygienic aspect. At the factory, no one carries out deep sanitary treatment of the internal chambers before packaging. There may remain industrial dust, microparticles of lubricant and remnants of packaging materials. That is why primary washing is a mandatory step in preparing equipment for work, and not just a recommendation.
Primary preparation and washing of the refrigerator
The first thing to do after delivering the equipment home and removing the outer packaging is to thoroughly wash all internal surfaces. Do not limit yourself to simply wiping with a damp cloth, since greasy stains from factory lubricant cannot be removed with water. You will need warm water and a mild detergent. A solution of baking soda or a weak solution of vinegar is ideal, which will not only clean, but also help neutralize primary odors.
Remove all removable elements: shelves, drawers, egg trays and door baskets. It is better to wash them separately in the bathroom or under the shower head, using a sponge with a soft abrasive side. Pay special attention to the corners and joints of the plastic where dust could accumulate. After washing, be sure to wipe all surfaces dry with a clean towel to avoid the growth of bacteria in a damp environment.
☑️ Primary processing checklist
Do not use for washing aggressive chemicals with chlorine or strong fragrances. Chlorine can react with plastic and increase the odor, and strong fragrances will simply mask the problem, creating an explosive mixture of aromas. It is best to use natural products or specialized household chemicals for the kitchen with a neutral pH.
Effective methods of ventilation
The simplest and most effective way to get rid of the smell of plastic is long-term ventilation. After cleaning thoroughly, leave the refrigerator and freezer doors completely open. Ideally, the device should stand in this form for at least 24 hours, and better yet, two days. A draft in the room will significantly speed up the process of weathering volatile substances.
If possible, you can use a fan. Direct the air flow into the open compartment of the refrigerator. Air circulation will help quickly remove odor-laden air from hard-to-reach places, such as the No Frost system ducts or the space behind the rear panel. However, you should not direct hot air from the heater, as a sharp temperature change can damage the plastic.
⚠️ Attention: Do not plug in the refrigerator during active ventilation if you do not plan to immediately load food. A running compressor creates vibration, which can interfere with the process of natural evaporation, and most importantly, you risk forgetting to close the door, which will lead to the engine running in vain and possible freezing of the evaporator.
It is important to ensure a flow of fresh air into the room itself where the equipment is located. A closed window and a running refrigerator will create a closed cycle where the smell will only circulate around the room. Open the window wide so that the air is renewed.
Folk methods of odor neutralization
If ventilation does not give immediate results, natural absorbents will come to the rescue. These substances are able to absorb odor molecules from the air, effectively cleaning the chamber space. One of the most popular methods is the use of activated carbon. It is enough to crumble 10-15 tablets and scatter them into saucers that need to be placed on the shelves of the refrigerator.
Baking soda has also proven itself to be excellent. It works as a soft absorbent and neutralizer of acidic odors. Pour baking soda into open containers or onto gauze pads and place them inside. A glass of coffee beans or ground coffee will also help to interrupt and absorb extraneous aromas, filling the chamber with a pleasant coffee spirit.
| Medicum | Method of application | Efficiency | Duration of action |
|---|---|---|---|
| Activated carbon | Crumble into saucers | High | Until replacement (3-5 days) |
| Baking soda | In an open container | Medium | Up to 1 week |
| Lemon zest | Fresh peel | Medium (masking) | 2-3 days |
| Rye bread | Pieces on a saucer | High | Until dry |
Don't forget about black bread. Pieces of rye bread laid out on shelves absorb odors perfectly due to their porous structure. After a couple of days, the bread needs to be replaced with fresh one. This method was used by our grandmothers and remains relevant due to its cheapness and availability.
Is it possible to use vinegar to eliminate odor?
Yes, you can. Wipe the inside walls with a weak solution of table vinegar (1 part vinegar to 3 parts water). However, after such treatment, the refrigerator must be thoroughly ventilated to get rid of the smell of the vinegar itself, which can be absorbed into the food.
Use of modern odor absorbers
The modern chemical industry offers many ready-made solutions to combat unpleasant odors. In household chemical stores you can find special odor absorbers for refrigerators. They are available in the form of gels, granules in containers or egg sachets. Such products often contain activated carbon, silicon dioxide or special chemical neutralizers.
A feature of modern absorbers is their targeted action. Some of them not only mask the smell, but also break down the molecules of odorous substances. For example, gel absorbers with bamboo extract or green tea not only eliminate odor, but also slightly aromatize the chamber, creating a feeling of freshness.
When choosing a product, pay attention to the composition. Safety is the main criterion, since the device will be located in close proximity to food. Avoid products with strong synthetic fragrances, which can transfer their taste to milk or butter. It is better to choose products marked “Food Safe” or “For food refrigerators.”
What you should absolutely not do
In an effort to quickly get rid of the smell of plastic, users sometimes make mistakes that can lead to damage to equipment. Firstly, do not use abrasive cleaning powders or hard metal sponges. They leave micro-scratches on the plastic, into which dirt and bacteria will subsequently become clogged, and it will be impossible to wash them.
Secondly, it is prohibited to use solvents, acetone or gasoline to clean plastic. These substances can melt the top layer of polymer, make it sticky or change color. In addition, solvent vapors themselves are toxic and take a long time to evaporate, creating an even more dangerous mixture.
⚠️ Attention: Never try to “burn out” the smell by leaving the refrigerator on with the door open at maximum cold or heat (if there is such a function). Sudden temperature changes can lead to deformation of plastic parts and disruption of seals.
It is also not recommended to use air fresheners for cars or rooms inside the refrigerator compartment. They contain volatile chemicals that will settle on food. Inhaling vapors from such aerosols along with food may cause an allergic reaction or food poisoning.
Preventing future odors
Once you have managed to overcome the smell of new plastic, it is important to maintain this result. Regular cleaning is the key to freshness. Once a month, it is recommended to wipe the shelves and walls with a weak solution of soda or a special product for caring for kitchen appliances. This will prevent the formation of plaque, which over time may begin to smell unpleasant.
Make sure the food packaging is sealed. Strong-smelling foods such as fish, smoked meats or blue cheese should be stored in tightly sealed containers. Refrigerator plastic has the ability to absorb odors, and if you keep an open herring on the shelf for a long time, it will be more difficult to remove this aroma than the smell of factory plastic.
Periodically check the expiration date of odor absorbers and change them. If you use traditional methods (charcoal, bread, soda), update them once a week. This will create a permanent barrier to any extraneous odors.
How often do you need to defrost the refrigerator to eliminate odors?
If you have a drip or No Frost system, complete defrosting is rarely required (once a year or according to instructions). However, for thorough cleaning and elimination of odors, it is recommended to completely unplug and wash the refrigerator at least once every 3-4 months.
FAQ: Frequently asked questions
How long does it normally take for the smell of a new refrigerator to disappear?
Usually the intense smell of plastic goes away within 3-7 days, provided regular ventilation and washing. The complete disappearance of all nuances of odor can take up to two weeks of active use. If the smell persists for more than a month, it is worth checking whether technical lubricant has got on the products or internal parts.
Is it possible to speed up the process using an ozonizer?
Yes, household ozonizers effectively destroy odors and bacteria. However, they must be used with caution: turn on the device inside a closed refrigerator, unplugged, for a short time (10-15 minutes), after which be sure to ventilate the chamber. Ozone in high concentrations is harmful to rubber seals.
Will washing the refrigerator with hot water help?
Using too hot water (above 40-50 degrees) is not recommended, as the plastic can be deformed. Warm water is quite effective when combined with detergent. The main thing is the mechanical removal of dust and dirt, and not the temperature of the water.
What to do if the smell appears after defrosting the old refrigerator?
This may indicate that stagnant water with bacteria has accumulated in the drainage system or evaporator. In this case, you need to clean the drainage hole (usually located on the back wall inside the chamber) using a brush or a cotton swab dipped in a disinfectant solution.
