An unpleasant smell in the refrigerator is a problem, familiar to many, even the most careful housewives. Sometimes it’s enough to forget a piece of spoiled meat on a shelf or spill milk to persistent aroma settle in a cell for weeks. In other cases, the smell may appear after a long power outage or when products with a strong amber are improperly stored. This cannot be ignored, since foreign odors can be absorbed into fresh products, changing their taste.
The first thing that comes to mind is to wash all shelves with soap and water. However, this is often not enough, especially if the source of the odor is the plastic interior lining or hard-to-reach drainage holes. In this article we will look how to effectively clean a refrigeratorwhich means really work and which can harm the equipment. You will learn about proven methods of neutralizing and preventing the appearance of unpleasant odors.
You should not put off solving the problem, hoping that it will “dissipate on its own.” Over time, odor-causing bacteria can multiply, which will require more serious measures, including calling a professional to replace the seal or filter. We have prepared a detailed guide that will help you return freshness to your food storage room quickly and safely.
Preparing for washing: defrosting and removing the contents
Before looking, how to wash a refrigeratoryou need to properly prepare the unit for procedure. The main mistake many people make is trying to wash the chambers while they are on and full of food. This is not only ineffective, but also dangerous for the compressor. Complete defrosting allows you to remove ice in which bacteria accumulate and get to all corners of the chamber.
First, disconnect the device from the power supply. Take out all the products, sorting them: throw away what is spoiled, and put what can be saved in a cool place or in a thermal bag. Remove all removable parts: shelves, vegetable drawers, egg trays and door containers. It is more convenient to wash them separately in a bathtub or large basin using warm water.
⚠️ Attention: Never use sharp objects (knives, screwdrivers) to chip ice inside the chambers. Damage to the evaporator will lead to a refrigerant leak and costly repairs.
Leave the doors open for at least 2-4 hours to allow the ice to completely melt and the water to drain. Prepare rags or sponges to collect melt water. If you have a model with a No Frostsystem, defrosting may take less time, but it is still necessary to check for moisture in the drainage system. Only after the interior space is completely free of ice and water can you begin to select a cleaning agent.
☑️ Preparing the refrigerator for washing
Folk remedies: soda, vinegar and lemon
The most affordable and safest way to wash the inside of the refrigerator from the smell is to use improvised means. They are non-toxic, cheap and often more effective than aggressive chemicals. The leader here is regular baking soda. It has excellent absorbent properties and a mild abrasive effect, which helps remove old stains.
To prepare the solution, dilute 2 tablespoons of soda in 1 liter of warm water. Thoroughly wipe all internal surfaces, including rubber seals, with this solution. After treatment, leave the product for 10-15 minutes, then rinse with clean water and wipe dry. Soda solution Ideal for removing greasy deposits and neutralizing sour odors.
Another powerful remedy is table vinegar (9%). It perfectly disinfects and kills mold fungi, which often cause mustiness. The solution is prepared in a 1:1 ratio with water. When working with vinegar, it is important to ventilate the area well, as the fumes can be harsh. After treatment with vinegar, the smell will quickly disappear, taking with it the unpleasant aroma from the chamber.
- 🍋 Citric acid or fresh lemon juice: adds pleasant freshness and dissolves scale.
- 🧼 Laundry soap: effective against greasy stains, but requires careful rinsing.
- ☕ Dry black tea or coffee: used as odor absorbers after washing.
- 🌿 Ammonia: a powerful remedy, but requires caution and good ventilation.
If you choose lemon, simply cut the citrus in half and wipe the cut side of the refrigerator wall. Or dissolve a packet of citric acid in water. This will not only eliminate the odor, but will also give the camera a light, subtle citrus aroma that will not overwhelm the smell of the food.
Danger of mixing products
Never mix vinegar and chlorine-containing products (for example, Bleach). The reaction releases chlorine gas, which is toxic and harmful to the respiratory tract. Use the products separately.
Professional and specialized products
When traditional methods seem ineffective or the situation is critical (for example, after the death of a rodent or a long period of downtime), household chemicals come to the rescue. The market offers many sprays and gels designed specifically for kitchen appliances. They contain enzymes active components that break down organic matter.
When choosing a product, pay attention to the label “for refrigerators” or “food contact”. This ensures that once dry the surface is safe for storing food. Popular brands, such as Top House, Electrolux, Sano, produce antibacterial sprays that do not require rinsing with water, which greatly simplifies the process.
| Remedy | Type | Action | Is it necessary wash off |
|---|---|---|---|
| Top House Spray | Antibacterial | Eliminates odors, kills 99.9% of bacteria | No |
| Sano Refrigerator Gel | Cleansing | Removes grease, plaque, disinfects | Desirable |
| Electrolux wipes | Wet | Express cleaning, polishing | No |
| Chlorhexidine solution | Antiseptic | Disinfection, mold removal | Yes |
Use of specialized chemicals justified if you need to quickly put your equipment in order before guests arrive or after purchasing a used refrigerator. However, remember that some components can be aggressive to low quality plastic. Always test the product in an inconspicuous area.
How to eliminate the smell after defrosting meat
The most difficult cases are the smell of rotten meat or fish, which has ingrained itself into the plastic, or “aroma” after prolonged defrosting, when mold could have developed in the chamber. In such situations, ordinary water will not help. You will need powerful absorbents and disinfectants.
If the source odor has already been eliminated (the product has been thrown away), but the background remains, try treating the surfaces with a solution of hydrogen peroxide. It oxidizes organic compounds, destroying odor molecules. You can also use a weak solution of potassium permanganate (light pink), which has strong disinfectant properties.
⚠️ Attention: When working with potassium permanganate, be careful not to make the solution too concentrated, otherwise it may color the white plastic pink or brown, which will be difficult to wash.
After wet processing, you must start the process "dry" neutralization. Place open containers with activated carbon (crush 10-15 tablets), ground coffee or salt on the shelves. These substances work like a sponge, absorbing odor molecules from the air. Leave them in the switched off refrigerator with the door open for a day.
In especially severe cases, when the smell does not go away, you can use an ozonizer. If you have a household air purifier, place it inside a closed refrigerator (through a hose or leaving the cord outside) and turn it on for 10 to 15 minutes. Ozone effectively destroys bacteria and odors, but after the procedure the chamber must be well ventilated.
Cleaning hard-to-reach places: drainage and sealants
This often happens: you washed all the shelves and walls, but the smell remains. Most likely, the source is hidden where the hand and sponge cannot reach. First of all, check drainage hole. It is located on the back wall of the refrigerator compartment (usually in the lower center). Condensation flows there, and if the channel is clogged with food crumbs or mucus, rotting begins.
To clean the drainage, use a special brush or soft wire wrapped in cotton wool. Rinse the canal with warm water using a syringe or syringe without a needle. You can pour a little soda solution there, wait and rinse again with clean water.
The second critical place is the rubber seal on the door. Dirt, juice and bacteria accumulate in its folds. Wipe the rubber with a cotton swab dipped in vinegar or alcohol. If the rubber is blackened by mold and does not wipe off, it may need to be replaced, since the porous structure of the rubber is already affected by fungus.
- 🔍 Remove the plastic covers and shelves on the door: mold often hides under them.
- 🌬️ Blow out the ventilation holes: use a vacuum cleaner on minimum power.
- 🧹 Check the space behind the refrigerator: dust on the condenser can also smell when heating.
Do not forget that some refrigerator models (especially those with No Frost) have a water drainage system that goes into a tray above the compressor. If the smell is coming from below, the problem may be there. Getting there is more difficult; you may need to move the refrigerator and remove the bottom panel.
Prevention: how to maintain freshness for a long time
So that the question “what to wash with refrigerator” does not get up every month, it is important to follow the operating rules. Freshness depends not only on cleanliness, but also on proper storage of food. Use airtight containers for prepared foods, fish and cheeses. This will prevent the mixing of flavors and the spread of bacteria.
Inspect the products regularly, at least once a week. Throw away anything that is in doubt. Wipe shelves with a damp cloth immediately after spills. Once every 3-4 months, it is recommended to completely defrost and wash, even if there is no visible dirt.
To maintain a pleasant microclimate, you can use natural odor absorbers that do not require replacement for months. This could be a bag of rice, an open pack of soda (which needs to be changed once a quarter), or special carbon filters for refrigerators.
Compliance with the temperature regime is also important. If the refrigerator does not work properly or the temperature is too high, food will spoil faster. Make sure that the door closes tightly and do not place hot foods inside the chamber.
Life hack with bread
A piece of black stale bread, left in an open plate on the refrigerator shelf overnight, perfectly absorbs foreign odors, acting as a natural sorbent.
Is it possible to wash a refrigerator with bleach or Domestos?
You can use chlorine-containing products (Belizna, Domestos) only in extreme cases for disinfection, for example, after storing meat with an infection. However, chlorine is aggressive to plastic and rubber and can cause them to yellow and deteriorate. In addition, the smell of chlorine is very difficult to remove and can be transferred to products. If you used bleach, thoroughly rinse the surfaces with water 3-4 times and leave the refrigerator open for a day.
Why did the smell appear after washing?
If the smell intensified after washing, you may have used too hot water (accelerated the growth of bacteria in the pores of the plastic) or did not rinse the detergent well enough, which itself has an aroma that mixes with the smell rotting. The cause may also be water that has entered the thermal insulation layer of the housing through cracks or drainage - in this case, drying will be required for several days.
How often do odor absorbers need to be changed?
Natural absorbers (soda, coffee, coal) lose their properties after 1-3 months. Soda and charcoal need to be changed once a quarter, coffee - once a month, as it can become moldy. Special industrial absorbers serve according to the instructions on the packaging, usually from 2 to 6 months.
Is the smell of mold in the refrigerator dangerous?
Yes, mold spores can settle on products, especially on those that are not heat-treated (cheeses, sausages, fruits). Consumption of such products may cause allergies or food poisoning. If mold has affected the seal or plastic parts deeply, it is better to replace them, since it is almost impossible to wash the mycelium out of the porous structure.
