An unpleasant smell in the refrigerator can ruin the taste of any dishes and create a feeling of discomfort in the kitchen. The most common source of the problem is spoiled food, especially meat, fish or dairy products that have spilled liquid on the shelves. Ignoring the problem can lead to the appearance of mold in hard-to-reach places and even failure of the air circulation system.
To eliminate odor forever, it is not enough just to wash the shelves with water. It is necessary to carry out comprehensive cleaning using disinfectants and odor absorbers. In this article, we will analyze proven methods that will help restore freshness to your equipment without calling a specialist.
The first step should always be complete defrosting if you have a drip system, or simply disconnecting from the network for models with No Frost. This will allow you to safely remove all removable elements and get to hidden contaminants, which are often the cause of persistent “stench”.
Primary processing and search for the source
Before grabbing rags and detergents, it is necessary to find and eliminate the very cause of the stench. Often, spoiled product can roll into the far corner or leak under the vegetable drawer. Carefully inspect all shelves, door pockets and seals.
If the odor comes from spilled liquid, it could have flowed into the technical openings. In models with automatic defrosting, water flows into a special tray above the compressor. If organic matter gets there, the smell will persist for years until you get to this node.
⚠️ Attention: When searching for the source of the smell, do not turn on the equipment until you are sure that all surfaces are completely dry. Moisture on electrical contacts can cause a short circuit.
Use a flashlight to detect hidden stains. Light at an angle will help you see old grease stains or dried food remains on the walls and ceiling of the chamber, which are not noticeable under normal lighting.
Dismantling and washing removable elements
The most effective way how to get rid of the smellis to wash everything that can be removed. Shelves, drawers, egg cups and bottle holders must be removed from the chamber and moved to the bathroom or outside.
Plastic parts and glass cannot be washed with hot water if they have been in the cold, since a sharp temperature change can cause the glass to crack. Allow parts to warm to room temperature for 15-20 minutes before water procedures.
For washing, use a sponge with a soft abrasive side and a high-quality detergent. Pay special attention to the corners of the drawers and the joints of plastic, where plaque most often accumulates.
- 🧼 Soak strong-smelling plastic containers in a soda solution for 30 minutes.
- 🚿 Rinse the parts with plenty of running water to wash off any remaining chemicals.
- 🌬️ Thoroughly dry all the elements before installing them back so as not to create dampness.
☑️ Preparing for washing
Do not forget about the rubber seals on the door. They need to be wiped especially carefully, pushing the folds apart, since this is where mold and food debris often hide.
How to clean the inside of the refrigerator from the smell
The choice of detergent plays a key role. Harsh chemicals can damage the plastic or leave their own lingering aroma that mingles with the food. It is better to use proven home recipes or specialized sprays.
Baking soda solution is a classic remedy that not only removes grease, but also neutralizes acidic odors. Two tablespoons of powder per liter of warm water is enough. It is safe abrasivethat does not scratch surfaces.
Acetic acid also works well against bacteria and fungi. Mix water and 9% table vinegar in a 1:1 ratio. After treatment with this solution, the room must be well ventilated so that the pungent smell of vinegar goes away, which, however, quickly disappears.
| Remedial | Proportion | Efficiency | Smell after treatment |
|---|---|---|---|
| Baking soda | 2 tbsp. l. per 1 liter of water | High | Absent |
| Table vinegar | 1:1 with water | Very high | Sharp, fast erodes |
| Citric acid | 1 sachet per 1 liter | Medium | Pleasant citrus |
| Laundry soap | Shavings solution | Average | Specific |
If you prefer household chemicals, choose products marked “for food surfaces” or “antibacterial.” Avoid chlorine-containing products, as their vapors can be dangerous when in contact with products.
Folk methods and natural absorbers
After wet cleaning, a subtle but unpleasant odor often remains. In this case, natural sorbents come to the rescue. They absorb odor molecules from the air and from surfaces.
Activated carbon is one of the most powerful natural filters. It is enough to crumble 10-20 tablets and scatter the powder into saucers that need to be placed on shelves. After a day, the smell should disappear.
Using rice and salt
Coarse table salt and rice also work as excellent adsorbents. Pour them into open containers and leave them in the chamber for 1-2 days. After use, salt and rice cannot be consumed as food; they should be disposed of.
Coffee grounds or ground coffee have a strong aroma of their own, which overpowers foreign odors, and the porous structure of the grains absorbs excess moisture and aromatic molecules.
- ☕ Ground coffee in an open bowl.
- 🍞 A piece of black bread (change every 12 hours).
- 🍚 Raw rice in a fabric bag.
- 🧂 Coarse salt.
Citrus peels also work great. Place fresh lemon, orange or grapefruit peel around the chamber. Essential oils not only mask the odor, but also have a slight antiseptic effect.
Professional products and equipment
If traditional methods do not seem effective enough to you or the situation is critical (for example, rotten fish has been lying in the refrigerator for a long time), you should turn to industrial solutions. Modern ozonizers and special sprays work wonders.
Ozonizers are small devices that produce ozone. This gas oxidizes bacteria and viruses, completely destroying the source of odor. It is enough to turn on the device for 10-15 minutes in a closed chamber to disinfect a volume of up to 300 liters.
⚠️ Attention: Ozone in high concentrations is dangerous to the respiratory tract. While the ozonator is operating, do not be in the kitchen, and after treatment, be sure to ventilate the refrigerator and kitchen for 20-30 minutes.
Odor neutralizer sprays for refrigerators contain enzymes that break down organic odor molecules rather than mask them. They are safe for food and often have a slight aroma or no smell at all.
There are also electronic air purifiers that constantly work inside the chamber, ionizing the air and preventing the growth of bacteria and the appearance of mold.
Prevention and care of the No Frost system
In refrigerators with the system No Frost odor may occur due to clogged drainage holes. The water flowing from the evaporator carries with it food particles and bacteria. If the hole is clogged, the water stagnates and begins to go out.
To clean it, use a special brush - a flexible wire or a cotton swab. Carefully insert the tool into the hole on the back wall (usually it is covered with a plastic plug) and clean the channel.
Regular check of timing product shelf life is the best prevention. Make it a habit to inspect your shelves once a week and throw away products that are past their expiration date.
Store food in closed containers. This will not only prevent the mixing of odors (so that the fish does not smell like strawberries), but will also protect the chamber from accidental spills and crumbs.
Is it possible to use bleach for washing refrigerator?
You can use chlorine-containing products (for example, “Belizna”) only in extreme cases for disinfection in case of severe bacterial contamination. However, chlorine has a very aggressive effect on plastic (it may turn yellow) and rubber seals (they will dry out). In addition, the smell of chlorine is very difficult to remove and can be absorbed into food. It is better to use hydrogen peroxide or vinegar.
How long does it take for the smell to disappear after cleaning?
If the source of the smell is eliminated and high-quality wet cleaning is carried out, followed by the use of sorbents (charcoal, soda), the smell should disappear within 24 hours. If the smell persists longer, it may have penetrated into the thermal insulation layer (polyurethane foam) through microcracks or drainage, which requires deeper cleaning or calling a specialist.
Does an ultraviolet lamp help?
Yes, quartzing the fridge compartment with an ultraviolet lamp (quartzizer) for 10-15 minutes effectively kills bacteria and mold that cause the odor. However, you need to use special lamps for household purposes and strictly follow the instructions so as not to damage the plastic of the camera and not get a burn to your eyes.
What to do if the smell is ingrained in the plastic of the boxes?
The plastic has a porous structure and easily absorbs odors. If regular washing doesn't help, try soaking the boxes in a citric acid solution or putting them in the freezer for a day (if size allows). Treatment with a steam generator also helps if the plastic is heat-resistant.
