An unpleasant aroma in the refrigerator can ruin your appetite and mood to any home cook. Often the problem arises suddenly: the products seem to be fresh, the shelves are wiped clean, and the persistent odor persists. This could be the result of a forgotten piece of meat, spilled milk, or the specific properties of new plastic.
Before running to the store for expensive chemicals, it is worth turning to time-tested methods. Folk remedies they are often more effective than aggressive sprays, since they do not just mask, but absorb or neutralize odor molecules. In this article we will look at how to save the situation using what is at hand.
The main rule is to act quickly. The longer the source of aroma is in a confined space, the deeper it is absorbed into rubber seals and plastic panels. Long-term ignoring problems can lead to the fact that even after eliminating the cause, the smell will remain.
Finding and eliminating the source of the problem
Any fight against the consequences is pointless without eliminating the cause. The first step should always be a complete audit of the contents of the cells. Take a close look at every corner, including door shelves and crisper drawers. Sometimes a spoiled product is hidden behind other packages.
Pay special attention to places where juice from defrosted meat or spilled milk could leak. Liquid could get into technical openings or under removable structural elements. Careful inspection helps to identify hidden pockets of contamination, which are the main culprits.
⚠️ Attention: If the smell of burning or scorched plastic appears suddenly and is accompanied by heating of the housing, immediately disconnect the device from network and call a technician. This may indicate a faulty wiring or compressor.
Once the source is located, it must be disposed of immediately. Do not try to save the product if there is even the slightest doubt about its freshness. Health is more valuable than the cost of damaged packaging.
General defrosting and washing
If a visual inspection does not produce results or the source has already been eliminated, but the aroma remains, complete defrosting is required. Modern models with the system No Frost also require periodic shutdown for hygienic processing, although ice does not accumulate in them.
The washing process requires consistency. First, wipe the defrosted chamber with a damp cloth, removing visible dirt. Then use a cleaning solution. It is important not to use abrasive sponges, which can scratch the plastic, making it more susceptible to absorbing odors in the future.
☑️ Refrigerator washing algorithm
Removable parts - shelves, drawers, grates - it is better to wash them separately in bath or shower. Use warm water and a mild detergent. Rinse them thoroughly so that there is no chemical film left on the surface, which itself can give off an unpleasant chemical odor.
Soda: a universal absorber
Baking soda is perhaps the most well-known and accessible remedy for combating odors. Its alkaline environment effectively neutralizes acidic odor components. To achieve the result, you can sprinkle the powder on the bottom of the chamber or wipe the surface with a solution (1 tablespoon per liter of water).
However, the dry adsorption method is more effective. Place the baking soda in a shallow bowl or leave the packet open and place it on a shelf. The soda crystals will absorb odor molecules from the air. This “trap” should be changed once a month for prevention.
The effectiveness of soda has been tested for decades. It is safe for products and non-toxic. If after treatment with the solution the smell does not go away completely, leave the containers with the powder inside the closed refrigerator for 2-3 days.
Vinegar and citric acid
Acetic acid does an excellent job of removing bacterial plaque and mold, which are often the hidden cause of odor. The solution is prepared in a 1:1 ratio with water. Wiping the inner walls with this solution disinfects the surface.
Citric acid or fresh lemon act similarly, but leave a more pleasant citrus aftertaste. You can place lemon slices on saucers in the chambers or wipe the plastic with a solution of citric acid. Organic acids break down fatty stains, which can also smell.
After treating with vinegar or lemon, the refrigerator must be ventilated. The pungent smell of vinegar disappears on its own within a few hours, taking other aromas with it. The lemon smell can remain longer, which is often perceived as a pleasant bonus.
| Medicum | Proportion | Method of application | Action time |
|---|---|---|---|
| Table vinegar (9%) | 1:1 with water | Wipe with a damp cloth | Until drying + airing |
| Citric acid | 1 sachet per 1 liter | Solution for wiping | Immediately after drying |
| Fresh lemon | 1 pcs. | Cut into slices, spread out | 24-48 hours |
| Ammonia | 1 tbsp. l. per 1 l | Wipe (with caution) | Requires long ventilation |
Activated carbon and natural sorbents
Activated carbon is a powerful adsorbent, used even in industrial filters. For the refrigerator, it is enough to crush 10-20 tablets and scatter the powder into containers. You can also use ready-made charcoal for barbecues (in small granules), having previously washed it from dust.
Natural sorbents work no worse than chemicals. Rice, coffee beans, silica gel balls (from bags that are placed in shoes) perfectly absorb moisture and odors. Dry rice left in an open jar on a shelf works wonders on stale air.
Ground coffee is also an excellent freshener. It not only removes extraneous odors, but also fills the chamber with a subtle coffee aroma. The main thing is to use a ground product, since it has a larger contact area with air.
The secret of activated carbon
Coal works due to the huge porous surface area. One granule of coal has a surface area comparable to a football field, which allows it to capture a huge number of odor molecules.
Specialized products and tea
Black tea without additives is another affordable option. Brew strong tea, cool it and wipe the walls of the refrigerator. The tannins contained in the tea leaves have a deodorizing effect. Used tea bags can also be placed inside, but only if they are completely cooled and do not leak.
If traditional methods seem too troublesome, special odor absorbers are sold in hardware stores. They come in the form of gel beads, carbon filters or electronic ozonizers. Electronic neutralizers they are battery operated and emit ions that kill bacteria.
⚠️ Attention: Do not use chlorine-containing products (for example, “Whiteness”) for washing the refrigerator. Chlorine vapor can be absorbed into plastic and rubber seals and then slowly released, poisoning food.
When choosing between tea and store-bought chemicals, assess the scale of the problem. Tea is good for easy prevention and elimination of mild odors, while for complex cases, specialized sprays or gels with enzymes are better suited.
Prevention of odors
In order not to constantly return to the issue of cleaning, it is important to follow the operating rules. All products with a strong odor (fish, smoked meats, garlic) should be stored in airtight containers. This is an axiom that cannot be violated.
Check expiration dates regularly. Get into the habit of inspecting your shelves once a week. Even one moldy piece of cheese can “flavor” the entire volume of the chamber.
Also keep the door seals clean. The folds of rubber often accumulate food debris and dirt, which begin to rot over time. Wipe the seals with a damp cloth every time you clean the kitchen.
Is it possible to wash the refrigerator with dishwashing detergent?
Yes, you can. Regular dishwashing detergent works well to degrease surfaces. The main thing is to rinse the foam very thoroughly with clean water several times so that the detergent does not get on the food.
How long should you ventilate the refrigerator after washing?
The optimal ventilation time is from 2 to 4 hours with the doors open. If vinegar or ammonia was used, it is better to increase the time to 6-8 hours or leave it overnight.
Why does the smell return after some time?
If the smell returns, it means the source has not been eliminated. Liquid may have leaked into the drain hole or under the plastic casing. Also, the reason may be in the old, porous seal, which has absorbed odors over the years of service.
How to remove the smell from a new refrigerator?
The smell of new plastic is normal. It is enough to wash the camera with water and soda or lemon and let it stand with the door open for 1-2 days. The use of chemical flavors in a new appliance is undesirable.
