An unpleasant odor in the refrigerator can spoil the mood of any owner and cause damage products. We often notice that even fresh dishes acquire a strange taste, and inside the chamber there is a persistent odor of spoiled food or mold. This problem is familiar to many, but not everyone knows how to properly and safely eliminate the source of aroma.
Before grabbing aggressive household chemicals, you need to understand the nature of the odor. Porous surfaces The plastic from which the internal shelves and walls are made absorbs odors perfectly. If you do not react in time to spilled milk or a forgotten piece of cheese, the aroma molecules will penetrate deeply into the structure of the material, and simple ventilation will not help here.
In this article we will analyze effective methods how to clean the refrigerator from the smell, using both improvised means and specialized cleaners. You will learn why you cannot use some popular solutions and how to prevent problems in the future, keeping the equipment in perfect condition.
Primary preparation and defrosting
Any quality cleaning begins with completely emptying the refrigerator compartment. You need to remove absolutely all products, remove removable shelves, vegetable drawers and egg containers. Only after gaining access to all surfaces can you count on deep cleaning hard-to-reach places where bacteria often accumulate.
If your refrigerator is not equipped with a system No Frost, complete defrosting will be a mandatory step. Ice crust not only reduces the efficiency of the compressor, but also hides many bacteria and sources of unpleasant odors. Leave the doors open for at least 5-6 hours, placing towels underneath to collect melted water.
⚠️ Attention: Never use sharp objects, knives or ice picks to chip ice. Damage to the evaporator will lead to a freon leak and expensive repairs, which can cost as much as half a new refrigerator.
While the defrosting process is in progress, take care of the removable elements. It is best to wash them in a bathtub or large basin with warm water. For plastic parts, soaking is ideal, as it will soften dried-on dirt. Don't forget to check the rubber seals on the doors - this is where black moldmost often hides, emitting a musty odor.
Folk remedies for removing odors
There are many available methods how to clean refrigerator odor, without resorting to expensive store-bought products. Baking soda is traditionally considered the leader here. It is an excellent absorbent and soft abrasive that does not scratch plastic. Dissolve 2 tablespoons of baking soda in a liter of warm water, thoroughly wipe all surfaces with a sponge, and then rinse with clean water.
Acetic acid also works wonders, especially if you need to eliminate the smell of fish or garlic. Mix table vinegar (9%) with water in a 1:1 ratio. Wipe the inner walls with this solution. Acetic acid It perfectly disinfects and neutralizes volatile aromatic compounds. After processing, be sure to ventilate the chamber, since the smell of vinegar itself is quite pungent, although it disappears quickly.
- 🍋 Lemon juice is a natural antiseptic that not only removes odors, but also leaves a fresh citrus aroma.
- ☕ Ground coffee - perfectly absorbs extraneous odors if you scatter it on saucers and leave it in the chamber overnight.
- 🍞 Black bread - a slice of black bread, left in an open plate on a shelf, works as a natural absorber of aroma.
Use ammonium alcohol with extreme caution and only in well ventilated area. It is effective against the most persistent odors, for example, if rotten fish has been lying in the refrigerator for a long time. However, its vapors are toxic, so after treating with ammonia, the refrigerator must dry with the doors open for at least a day.
Professional household chemicals
If traditional methods do not seem effective enough to you or you want to save time, household chemicals will come to the rescue. Modern products are designed taking into account the materials used in the manufacture of refrigerators. They contain antibacterial componentsthat kill microbes that cause odor, rather than simply masking them.
When choosing a product, pay attention to the mark “for food surfaces” or “safe for children and animals.” Harsh chlorine solutions can damage plastic, making it yellow and brittle, and leave a chemical odor that transfers to food. Sprays with a dispenser are more convenient to use, as they allow you to treat hard-to-reach corners.
There are also special wet wipes for household appliances. They are convenient for express cleaning, but they may not be enough to remove old odors. In this case, it is better to use cleaning sprays that are applied to the surface, left for 5-10 minutes to act, and then washed off or wiped with a dry cloth.
Comparison table cleaning methods
To make it easier for you to choose how to clean a refrigerator from odor in your specific case, we have prepared a comparison table of popular methods. It will help evaluate the effectiveness, safety and labor costs of each method.
| Method | Efficiency | Safety for plastic | Odor resistance after |
|---|---|---|---|
| Baking soda | Medium | High | None |
| Vinegar 9% | High | High | Sharp (weathers) |
| Ammonia | Very high | Medium | Sharp (takes a long time to erode) |
| Special. sprays | High | Depends on the composition | Chemical/Fragrance |
| Citric acid | Medium | High | Citrus |
As can be seen from the table, the most versatile and safe option is baking soda, however, for complex cases, a more powerful effect may be required.
Cleaning the No Frost system and drainage
Owners of modern models often wonder why there is a smell in the refrigerator with the system No Frostif it seems to be clean. The answer lies in hidden design elements. In such refrigerators, air circulates through special channels, and if bacteria settles there or liquid gets in, the smell will spread throughout the entire chamber.
Particular attention should be paid to the drainage hole. It is usually located on the back wall inside the camera. It is through this that the condensate flows into the tray above the compressor. If the hole is clogged with crumbs or mold, the water stagnates and begins to smell unpleasant. You can clean it using a special brush or a cotton swab dipped in a disinfectant solution.
⚠️ Attention: The design of refrigerators from different manufacturers may vary. Before disassembling the internal panels to access the fan or evaporator, check the instructions or contact a service center so as not to violate the warranty.
For deep cleaning of the ventilation system, you can use a spray with a long spray tube. Spray the inside of the vents (after covering the food or removing it) so that the product gets onto the fan blades and the walls of the air ducts. This will help eliminate odor, the source of which is not visually visible.
Odor absorbers: working and useless
After general cleaning, it is important to consolidate the result. There are many odor absorbers on the market, but not all of them are equally useful. Activated carbon remains one of the best adsorbents. You can buy special briquettes for the refrigerator or simply crumble a few tablets of ordinary pharmaceutical charcoal and pour them into a container with holes.
Gel absorbers work on the principle of absorbing moisture along with odor molecules. They are convenient because they have an indication: when the gel changes color or decreases in volume, the cartridge needs to be replaced. However, their effectiveness is limited by the small volume of the chamber and strongly depends on humidity.
- 🌿 Natural absorbents (rice, salt, soda in an open container) are cheap, but require frequent replacement (every 1-2 weeks).
- 🔋 Electric ionizers are expensive, but effectively kill bacteria and remove odors ozonation.
- 🍋 Citrus zest gives a pleasant aroma, but after a couple of days it begins to rot and smell itself, requiring replacement.
You should not rely only on flavorings that mask the smell, but do not eliminate its cause. If you smell rot, no “sea freshness” in the form of a spray will help until the source of the problem is found and removed. Adsorption and removing bacteria is the key to success.
☑️ Checklist for perfect cleaning
Prevention of unpleasant odors
The best way to deal with odors is to prevent them. Following food storage rules will help you forget about the problem forever. Always pack food in containers with tight-fitting lids or use plastic wrap. Open pots and plates are the main enemy of cleanliness in the refrigerator.
Regularly audit your inventory. Make it a habit to throw out expired food items once a week. Even one forgotten tomato in the vegetable drawer can create a catastrophic smell after a couple of weeks. Wipe the shelves with a damp cloth immediately if something is spilled or scattered.
What to do if the smell remains after cleaning?
If the smell persists after thorough washing, it may have been absorbed into the rubber seals. Try wiping them with a hydrogen peroxide solution. In the worst case, if the smell has penetrated into the thermal insulation layer (which happens when the housing is damaged), the insulation or even the entire chamber will need to be replaced, which is not economically feasible.
Monitor the temperature conditions. If the refrigerator is too warm, food will spoil faster. The optimal temperature in the main chamber is +2..+4°C, in the freshness zone - 0°C. Use a thermometer for the refrigerator to monitor the operation of the equipment.
Is it possible to wash the refrigerator with soap?
Use regular toilet or laundry soap not recommended. It is poorly washed off from plastic surfaces, leaving a sticky residue and a specific odor that can be transferred to products. It is better to use products intended for washing dishes (they are washed off better) or specialized sprays.
How to remove the smell after defrosting?
If a damp smell appears after defrosting, wipe all surfaces with a solution of vinegar or citric acid. Be sure to leave the doors open until completely dry. You can put a bowl of activated carbon or soda inside for a day for final adsorption.
Is it safe to use bleach (White)?
Chlorine-containing products effectively kill mold, but they are aggressive for plastic and rubber. Bleach can cause shelves to yellow and seals to deteriorate. In addition, the smell of chlorine is very persistent and can be absorbed into food. Use it only in extreme cases and wash it off very carefully.
Why does a new refrigerator have a strange smell?
The smell of plastic in a new refrigerator is normal. It comes from new materials. Before first use, the new unit should be washed with warm water and soda and left with the doors open for 1-2 days. This will allow technical odors to disappear.
