Suddenly appearing or persistent unpleasant odor in the refrigerator is not just discomfort, but a signal that that bacteria or mold have settled inside. Housewives often try to mask the aroma with air fresheners, but this is only a temporary solution that does not eliminate the root of the problem. In order to forget about the stench once and for all, it is necessary to carry out general cleaning following certain rules and sequence of actions.
Before grabbing a rag, it is important to understand the nature of the pollution. The source could be spilled milk that has flowed under the tray, or a spoiled piece of meat forgotten in the freezer. Porous surfaces Plastic and rubber seals instantly absorb aromas, so ordinary ventilation will not help here. You will need an integrated approach, including defrosting, disinfection and proper drying.
In this article we will analyze proven methods that will help revive even the most neglected unit. You will find out which household products really work and which ones can damage the camera coating. Following the instructions will restore freshness to the equipment and protect products from re-infection with pathogenic microflora.
Initial preparation and defrosting
Any high-quality cleaning begins with the complete release of the internal space. Remove all shelves, crisper drawers and containers. If your model removable plastic elements, it is better to wash them separately under running water using dishwashing detergent. This will allow you to reach every corner of the main chamber.
The next critical step is defrosting. Even if you have a modern system No Frostthat does not require manual defrosting of ice, to eliminate the smell you need to unplug the device. Leave the doors open for at least 2-3 hours. During this time, volatile compounds will have time to evaporate, and the inner walls will warm up, which will facilitate the removal of contaminants.
⚠️ Attention: Never use sharp objects (knives, screwdrivers) to chip ice. Damage to the evaporator or internal circuit will lead to a refrigerant leak and expensive repairs, which are often not economically feasible.
While the unit is defrosting, inspect the products. Ruthlessly throw away anything that is in doubt about its freshness. Pay special attention to sauces, open cans and processed meats. They are the ones who most often become the source sulfur compoundsthat creates that very rotten smell.
Effective folk remedies for eliminating odor
When the chamber is emptied and dried, it is time to treat the surfaces. Chemical sprays often leave their own pungent aroma, which is then transferred to products. Folk methods In this regard, they win because they are safe, environmentally friendly and do not require rinsing with large amounts of water.
The leader among home cleaners is ordinary table vinegar. The acidic environment perfectly neutralizes alkaline odors and kills bacteria. Dissolve vinegar and water in a 1:1 ratio, pour into a spray bottle and thoroughly treat all walls. After this, wipe the surface with a clean damp cloth. To enhance the effect, you can add a few drops of lemon or mint. or old oil.burning odorsTo wash glass shelves, use a solution of ammonia (1 tablespoon per liter of water) - it will add shine to the glass and disinfect the surface better than any chemistry.Professional household chemicals and specialized productsIf traditional methods do not seem effective enough to you or the smell is too persistent, the modern chemical industry will come to the rescue.

Another powerful remedy is baking soda. It works as a soft abrasive and an excellent adsorbent.

Baking soda is ideal for removing fatty deposits, which can also store burning odors or old oil.

☑️ Checklist for proper washing
Cleaning hard-to-reach places and drainage system
It often happens like this: everything seems to be washed, the shelves are shining, but the smell remains. In 90% of cases, the problem lies where the hand or eye cannot reach. The first suspicion falls on drainage hole. It is located on the back wall of the refrigerator compartment and serves to drain condensate. If it becomes clogged with mucus or crumbs, rotting begins there.
To clean the channel, use a special brush (often included) or a cotton swab twisted into a rope. Carefully work your way inside the hole, being careful not to pierce the wall of the canal. Then fill a syringe without a needle with warm water and vinegar and flush the system under pressure. Water should flow freely into the pan.
⚠️ Attention: The design of the drainage system in different models Bosch, LG or Indesit may differ. Before aggressive cleaning, check the instructions so as not to damage the sensitive elements of the water drainage system.
The second place that everyone forgets is rubber seal on the door. Dirt and mold accumulate in the folds of corrugated rubber. Wipe the seal with a cotton swab dipped in hydrogen peroxide or vinegar. If the rubber has turned black and does not rub off, it may need to be replaced, since fungus has already settled in the structure of the material.
What to do if the smell is absorbed into the plastic?
If after a thorough washing the plastic still smells, try putting an open pack inside for a day soda, activated carbon or a cup of ground coffee. These adsorbents will draw out the remaining odor from the pores of the material.
How to eliminate the smell after defrosting and turning it off
The situation when the refrigerator has been turned off for a long time (for example, when moving or repairing) requires a special approach. The musty smell of stagnant air penetrates very deeply. Simply washing the walls with water will not be enough; long-term drying is necessary. disinfection and long drying.
Use a solution of potassium permanganate (light pink) or chlorhexidine from the pharmacy. These antiseptics will kill bacteria that have grown in a damp, cold environment. Thoroughly wipe down all surfaces, including the ceiling of the chamber. After treatment, leave the doors open for a day, ensuring a draft in the room.
If the smell persists, you can resort to “heavy artillery” - treatment with a steam generator. Hot steam under pressure penetrates the micropores of the plastic and kills any organic matter. However, be careful: not all types of plastic are designed for high temperatures high temperatures, so keep the nozzle at least 10 cm away from the wall.
Prevention of unpleasant odors
So that the question “how to clean the refrigerator” does not arise too often, it is important to follow the operating instructions. The main enemy of freshness is storing food in open containers. Use airtight containers or cling film. This will prevent the mixing of odors and the spread of bacteria.
Inspect your inventory regularly, at least once a month. Throw away expired products. Wipe the shelves with a damp cloth, even if there is no visible dirt. To maintain freshness, you can use special odor absorbers based on zeolite or silica gel.
Also monitor the temperature regime. If the chamber is too warm, food will spoil faster. Check the thermostat settings. For the refrigerator compartment, the optimal temperature is +2...+4°C, for the freezer - -18°C and lower.
Is it possible to use bleach (White) to clean the refrigerator?
You can use chlorine-containing products only in extreme cases, for example, when mold is detected. However, chlorine is very toxic and takes a long time to dissipate. After treating with bleach, the refrigerator must be washed with clean water several times and ventilated for at least a day, otherwise the food may absorb harmful fumes.
Why does the smell return a week after cleaning?
Most likely, the source of the smell has not been eliminated. Check the drain hole, the space behind the rear panel (if accessible) and the rubber seal. Also, the smell may come from the rear of the engine compartment if liquid or a rodent has gotten in there.
How often do you need to defrost the refrigerator for cleaning?
Models with manual defrosting require turning off every 3-4 months. It is enough to defrost and wash No Frost systems 1-2 times a year, but preventive cleaning of shelves should be carried out monthly.
What is the best way to wash glass shelves?
It is best to use warm water with the addition of ammonia or window cleaner. They do not leave streaks and dry quickly. Avoid abrasive powders, which can scratch the glass.
