Unpleasant aroma that suddenly appeared in refrigerator, can ruin the taste of even the freshest food and turn the cooking process into torture. Housewives are often faced with a situation where standard washing with warm water does not produce results, and the “odor” returns after a few hours. To effectively eliminate the problem, it is necessary not only to mask the odor, but to destroy its source, which can be bacteria, mold, or aromas absorbed into the plastic.
Before reaching for aggressive chemicals, it is important to understand the nature of the contamination. If milk accidentally leaked in the chamber or meat spoiled while you were away, regular dish spray may not be able to cope with the grease and organic matter. A properly selected product will allow disinfect the surface, without damaging the plastic seals and coating of the shelves.
In this article we will analyze proven cleaning methods, from affordable home recipes to professional solutions. You will learn how to properly prepare equipment for washing, what tools to use and how to prevent the appearance of odors in the future, preserving the performance of your Primary preparation and search for the source of the problem unit for many years
Initial preparation and search for the source of the problem
Effective odor control begins long before before you open a bottle of cleaning product. The first and most important step is to completely defrosting and release the cameras. Even if you have a modern refrigerator with a No Frost system, you need to unplug it for at least a few hours so that the glass and plastic warm up to room temperature.
Warm air helps open the pores of the plastic, which makes it much easier to wash out dirt. While the equipment is thawing, carefully sort through all the products. Often the source of the stench is a small bag of forgotten sauce or a piece of cheese that has rolled into the far corner.
⚠️ Attention: Never try to speed up the defrosting process by scraping off the ice with a knife or placing a bowl of boiling water inside. Sudden changes in temperature can cause the evaporator tubes to rupture, which will require expensive repairs.
After removing all the products, remove all removable elements: shelves, vegetable drawers, bottle holders and egg trays. It is better to wash them separately in a bathtub or large basin using hot water and a sponge. Pay special attention to sealing rubber bands on the doors - it is in their folds that mold and dirt most often accumulate, which give a persistent odor.
While the parts are drying, inspect the inner surface. If you find traces of mold in the form of black dots, regular wiping will not help. Treatment with special agents or concentrated solutions will be required, which we will discuss later. Also check the drainage hole on the back wall of the chamber - its clogging often leads to stagnation of water and the appearance of a musty aroma.
Folk remedies for eliminating odors
If the cause of the unpleasant aroma lies not in rotting, but simply in the mixing of odors of different products, time-tested folk methods do an excellent job. They are safe, cheap and, as a rule, do not require rinsing with large amounts of water. The leader among such products is baking soda.
To prepare a cleaning solution, dilute 2-3 tablespoons of soda in a liter of warm water. Use the resulting liquid to wipe all interior surfaces, shelves and drawers. Soda works as a mild abrasive and excellent absorbentabsorbing foreign odors. After treatment, just wipe the surfaces with a clean, damp cloth.
Why is soda better than vinegar for plastic?
Acetic acid, although it disinfects, with frequent use can make the plastic more dull and rough, which will make it easier for dirt to stick in the future. Soda, on the other hand, acts more gently and does not damage the structure of the polymers, maintaining the smoothness of the walls of the refrigerator.
Another effective remedy is ammonia. It is especially good if spoiled meat or fish has been in the refrigerator for a long time. Dissolve one tablespoon of ammonia in a liter of water, wipe the chambers and be sure to leave the door open for ventilation for 2-3 hours. Ammonia vapor quickly disappears, taking with it an unpleasant odor.
- 🍋 Citric acid - perfectly breaks down fatty deposits and leaves a fresh citrus aroma.
- ☕ Ground coffee - is used as a dry odor absorber, which you just need to pour into a plate and leave in camera.
- 🍞 Black bread - a few slices of black bread, laid out on shelves, can absorb the smell in one night.
- 🧂 Salt - a strong saline solution disinfects and removes odor, but requires careful rinsing to avoid corrosion.
If the smell is deeply ingrained in the plastic, more powerful “heavy artillery” or repeated procedures may be required.
Household chemicals: what to choose for washing
When home recipes do not help, household chemicals come to the rescue chemistry. However, it is important to be careful here: many harsh products can damage the plastic or leave toxic residues that will then end up in your food. Choose products marked “for food surfaces” or “antibacterial.”
Chlorine-based sprays, such as “Belizn” or its analogues, have proven themselves, but they must be used with extreme caution. Chlorine is excellent at killing mold and bacteria, but its vapors are toxic and the smell is very persistent. After treating with a chlorine-containing product, the refrigerator must be washed with clean water at least 2-3 times and ventilated for a long time.
A safer alternative is products with active oxygen. They effectively break down organic contaminants and do not have such a suffocating odor as chlorine. You can also use regular dishwashing detergents, but they need to be rinsed very thoroughly, otherwise the foam will interfere, and the chemical taste may be transferred to the products.
There are specialized sprays for refrigerators, which often contain silver ions. Such products not only clean, but also create a protective film that prevents the growth of bacteria for some time. This is an excellent option for prevention, especially in families with small children.
Comparison table for cleaning products
To make it easier for you to navigate the variety of methods, we have compiled a comparison table. It will help you choose the optimal solution depending on the type of pollution and available resources.
| Remedial | Effectiveness against odor | Safety for plastic | Necessity of rinsing |
|---|---|---|---|
| Food grade soda | Medium | High | Desirable |
| Vinegar 9% | High | Medium | Required |
| Ammonia | Very high | High | Required |
| Products with chlorine | Maximum | Low (risk of fading) | Required (repeatedly) |
| Special. sprays for refrigerators | High | High | Depends on the instructions |
As can be seen from the table, there is no universal remedy. For easy prevention, it is better to use soda or specialized sprays. If the situation is critical (for example, the power went out and the food spoiled), you will have to resort to stronger compounds like ammonia or chlorine, taking precautions.
When using any chemicals, be sure to wear gloves and ensure a flow of fresh air into the room. Vapors from cleaning products can cause a headache or an allergic reaction, therefore ventilation kitchen cleaning is mandatory.
Cleaning hard-to-reach places and drainage
It often happens like this: the refrigerator is washed until it shines, the shelves shine, but the smell remains. In 90% of cases, a clogged drain hole is to blame. It is located on the back inner wall of the refrigerator compartment, usually in the center. Through it, the condensate flows into a tray above the compressor and evaporates.
If crumbs, mucus or mold get into the hole, the water stagnates and the process of rotting begins. You can clean it with a cotton swab, a long brush or a special flexible cable. Carefully, without fanaticism, push the tool inside the channel, cleaning the walls.
☑️ Checking the drainage system
Also, do not forget about the condensate collection tray, which is located at the back of the refrigerator, above the compressor motor. Water flows there from the drainage channel. The heat from the compressor usually causes the water to evaporate, but if dirt gets in, it turns into a black sludge with a terrible smell. You can get to it by moving the refrigerator away from the wall.
⚠️ Attention: When cleaning the back of the refrigerator, be extremely careful with the heat exchanger (black grille at the back). It is very easy to damage, and repairs in this case will be very expensive. Do not use sharp objects near it.
Another hidden source of odor can be the ventilation holes between the chambers (in models with one compressor). If a smell from the freezer (such as fishy) penetrates into the refrigerator compartment, the problem may be there. Wipe the ventilation grill with a damp cloth with a disinfectant.
How to get rid of the smell of plastic in a new refrigerator
A separate topic is the smell of new plastic, which is present in newly purchased appliances. It is not dangerous, but may give foods an unpleasant aftertaste. Usually it disappears on its own in 3-5 days, but the process can be accelerated.
The first thing to do is to thoroughly wash the new refrigerator with warm water and soap or soda before turning it on for the first time. This will remove factory grease and dust. After this, wipe the surfaces dry and leave the doors open for a day.
If the smell persists after switching on, put a few pieces of black bread, lemon slices or an open jar of salt inside. These products will act as absorbents while the plastic sits. You should not fill a new refrigerator with food right away - let it run empty for at least 2-3 hours.
Some users advise wiping new surfaces with vodka or alcohol. This really helps to degrease the plastic and remove the specific “technical” aroma, but after this procedure the refrigerator must be washed with clean water.
Prevention of unpleasant odors
The best way to deal with odors is to prevent them. Following simple hygiene rules will allow you to forget about the problem forever. First of all, make sure that the food packaging is sealed. Store liquid products, meat and fish only in closed containers or under cling film.
Check your supplies regularly. Make it a habit to check expiration dates once a week and throw away foods that are starting to spoil. Even one forgotten cucumber can become a source of problems in a couple of days.
Use natural odor absorbers on a permanent basis. There are special activated carbon balls on sale that can be recharged in the sun, or regular gel boxes. You can simply put them on the shelf, and they will neutralize aromas.
- 📅 Cleaning schedule — carry out a general cleaning of the refrigerator at least once every 3-4 months, even if there is no visible dirt.
- 🌡️ Temperature control —make sure that the refrigerator operates in the correct mode. Too high a temperature accelerates the spoilage of food.
- 🧼 Dryness —after washing, always wipe surfaces dry. A humid environment is ideal for the growth of bacteria.
Remember that cleanliness in the refrigerator is not only a matter of comfort, but also a matter of the health of your family. Regular care extends the life of equipment and maintains food freshness.
Is it possible to wash a refrigerator with window cleaner?
You can use window cleaners, but with caution. They remove grease well and do not leave streaks on glass shelves. However, they often contain alcohol and fragrances, which can be aggressive to some types of plastic or sealants. It is better to choose products without acetone and chlorine.
How often do you need to defrost the refrigerator for washing?
Refrigerators with manual defrosting require defrosting 1-2 times a year (or when a layer of ice forms 0.5 cm). No Frost systems do not need to be defrosted, but it is also recommended to wash their internal chamber with the mains disconnected 1-2 times a year for disinfection.
What to do if the smell remains after all the procedures?
If thorough washing and ventilation did not help, the smell may have been absorbed into the thermal insulation material of the case (this happens with strong leaks inside body). In this case, ozonizers or professional dry cleaning can help, but sometimes it is necessary to replace the seals or even the internal plastic.
