An unpleasant odor in the refrigerator is a problem that sooner or later every owner of household appliances faces. Sometimes the aroma is barely perceptible, and in other cases it can spoil the taste of even hermetically packaged products. The main reason lies in the growth of bacteria, food debris or spoiled products that could be lost in the far corners of the chamber.
Before running for chemistry, it is necessary to carry out an audit content. Often the source of the stench is a forgotten piece of cheese or spilled milk that has flowed under the drawers. If the products are in order, but the smell remains, then it’s time for general cleaning the unit. In this article, we will look at how to effectively clean the inside of the refrigerator from odor and how to prevent its occurrence in the future.
There are many ways to refresh the interior space, from time-tested folk remedies to modern household chemicals. The method you choose depends on how persistent the aroma is and what material your refrigerator shelves are made of. It is important to act carefully so as not to damage the plastic and rubber seals.
Why does an unpleasant odor appear?
Understanding the nature of the odor helps you choose the right product to eliminate it. Most often, the culprits are bacteria that actively multiply in a warm and humid environment. Even a short-term power outage could lead to spoilage of food, the smell of which was absorbed into the plastic walls chambers.
Another common reason is a clogged drainage hole. Water generated during defrosting or condensation should drain into a special tray. If the channel is clogged with crumbs or mold, the liquid stagnates and begins to rot, emitting a heavy aroma. Also, the source of problems may be a new refrigeratorwhich has not yet “caught its breath” after the factory, or an old unit that requires replacement of seals.
⚠️ Attention: If a burning or chemical smell suddenly appears in a working refrigerator, immediately unplug it and check the wiring or compressor. This may be a sign of a malfunction, and not just contamination.
Sometimes the smell comes not from the inside, but from the outside. For example, if there is a trash can next to the refrigerator or there are rotten vegetables. In such cases, a simple wash will not help until the external source is eliminated. It is also worth checking the expiration date of all spices and sauces stored on the door.
Preparing for washing the refrigerator
High-quality cleaning is impossible without proper preparation. The first step is to completely empty the chambers of food. All contents must be removed, sorted and damaged. If the products are good, but they smell, it is also better to temporarily transfer them to a cool place or wash the packaging.
Next, you need to disconnect the refrigerator from the power supply. This is a safety requirement and a condition for proper defrosting. Even if you have a system No Frost, letting the unit stand turned off for 15-20 minutes before washing will be useful to stabilize the pressure in the system. All removable elements - shelves, drawers, trays - need to be removed.
☑️ Preparing for washing
Removable parts are best washed separately in a bathtub or large basin. Plastic and glass can crack due to sudden changes in temperature, so use warm rather than hot water. While the parts are soaking, you can work on the inner walls of the case.
Folk remedies for odor removal
Many housewives prefer to use time-tested home remedies that are found in every kitchen. They are safe, cheap and often more effective than aggressive chemicals. One of the leaders is ordinary baking soda. It perfectly absorbs odors and degreases surfaces.
To prepare the solution, dilute 2 tablespoons of soda in a liter of warm water. With this solution you need to wipe all the walls, bottom and ceiling of the chamber. Baking soda is non-toxic, so it is suitable for cleaning refrigerators where food for children is stored. After treatment, the surfaces do not require thorough rinsing, just wipe them with a clean damp cloth.
Another powerful tool is acetic acid. It kills bacteria and neutralizes odors. Mix water and 9% table vinegar in a 1:1 ratio. Wipe all surfaces with this solution. The only negative is the pungent smell of vinegar, which, however, quickly disappears.
- 🍋 Lemon juice is a natural antiseptic that leaves a fresh citrus aroma. Wipe the walls with a slice of lemon or a solution of juice and water.
- ☕ Coffee grounds are an excellent absorbent. Dry grounds can be placed in saucers inside the refrigerator after washing.
- 🧂 Ammonia - helps remove very persistent, old odors. Wear gloves and ventilate the room.
- 🌿 Laundry soap - washes grease well, but requires careful rinsing so that no sticky residue remains.
Household chemicals and specialized products
If traditional methods seem insufficient to you or you prefer ready-made solutions, the market offers wide selection of household chemicals. It is important to choose products designed specifically for kitchen surfaces or refrigerators. They, as a rule, do not contain chlorine and aggressive solvents that can damage plastic.
Spray kitchen cleaners with an antibacterial effect are popular. They are easy to apply and often contain fragrances. However, you should be careful with flavorings: a strong chemical smell can be transferred to products, especially butter and milk.
| Mediculer | Efficiency | Safety | Features of use |
|---|---|---|---|
| Soda food | High | Absolutely safe | Requires solution preparation |
| Vinegar 9% | High | Safe | Pungent odor when applied |
| Special. sprays | Average | Requires rinsing | Ease of use |
| Chlorine-containing | Maximum | Dangerous for plastic | Only for severe mold |
When using household chemicals, always read the instructions on the package. Some products require repeated rinsing with water. Never mix different cleaning products, especially those containing chlorine and ammonia, as this can lead to the release of toxic gas.
How to eliminate odor after defrosting
After defrosting, the refrigerator often smells of dampness or stagnant water. This is normal, but requires the correct approach to drying. If you simply close the door, the smell will be preserved and only become stronger. After washing with any of the selected products, be sure to wipe all surfaces dry with clean microfiber or paper towels.
Pay special attention to hard-to-reach places: corners, shelf joints, rubber seals on the door. This is where moisture most often accumulates and mold forms. The seals must be carefully folded back and the folds washed with a cotton swab dipped in hydrogen peroxide or vinegar solution.
⚠️ Attention: Do not use a hair dryer to dry the internal surfaces of the refrigerator. Hot air can deform thin plastic or damage the cooling system.
After the camera has been washed and wiped dry, leave the doors open for at least 2-3 hours, preferably overnight. A draft will help to completely remove any remaining moisture and smell of detergents. If the smell of dampness remains, put an activated carbon tablet inside.
Prevention of odors
The best way to deal with odors is to prevent their occurrence. Regular inspection of products will help avoid situations where something goes bad unnoticed. Try to store liquid and strong-smelling foods in closed containers. This will not only keep the air fresh, but will also extend the shelf life of the products themselves.
Use odor absorbers. These can be special balls that are sold in stores, or homemade products. For example, a bag of rice and a few drops of vanilla, or an open pack of soda covered with gauze.
Secret places for cleaning
Pay attention to the ventilation holes inside the chamber. Dust and fluff often accumulate there, which begin to smell when wet. Gently go over them with a dry soft brush.
- 📦 Store food in closed containers, not in open bags.
- 🗓️ Once a month, do a quick check of expiration dates.
- 🧽 Wipe up spills immediately, not waiting until the end of the week.
- 🌬️ Do not put hot foods in the refrigerator - this provokes the growth of bacteria.
If you store meat or fish, make sure they are securely packaged. Even short-term storage of an open piece can lead to the impregnation of the porous plastic of the chamber with a specific aroma, which is then very difficult to remove. In such cases, freezing helps: put a bowl of water in the chamber, let it freeze, and then defrost - the ice will absorb some of the odors.
FAQ: Frequently Asked Questions
How to quickly remove the smell of fish from the refrigerator?
A solution of vinegar or lemon juice will help best. Wipe all surfaces thoroughly, paying special attention to the shelf where the fish was stored. After this, place cotton pads soaked in vinegar inside and close the door for an hour.
Is it possible to wash the refrigerator with bleach?
You can use bleach (for example, “Whiteness”) only in extreme cases to disinfect mold and only on white surfaces. Chlorine is aggressive to plastic and rubber seals, making them brittle. After treatment with bleach, very careful repeated rinsing is required.
Why does it smell like rotten meat, although all the products are fresh?
Perhaps the source of the smell is outside the unit (underneath, behind it) or in the drainage system. Check the condensate tray (often located above the compressor at the back) - mold or bacteria could have grown there.
How often should you wash the refrigerator?
General washing with defrosting is recommended every 3-4 months. However, you should wipe the shelves weekly with a damp cloth and check for spilled liquids or crumbs.
How to wash a new refrigerator before turning it on for the first time?
A new refrigerator must be washed before use to remove factory dust and industrial odors. Use a weak solution of soda or special dishwashing detergents, then rinse thoroughly with water and wipe dry.
