Regular cleaning of the refrigerator is not just a matter of aesthetics, but a critical procedure for maintaining the health of all family members. The inside of the refrigerator creates an ideal environment for the growth of bacteria, where crumbs, spilled liquids and food vapors settle. If you ignore this process, pathogenic microflora begins to actively spread, spoiling the freshness of even those products that were hermetically packaged.
Many housewives and owners are wondering what is the best way to wash the inside of the refrigerator, so as not to harm the coating and effectively destroy odors. Store-bought chemicals often contain aggressive components that can be absorbed into plastic shelves or rubber seals and then end up in food. That is why folk remedies remain the most popular and safe choice for delicate but thorough cleaning.
In this article we will look in detail at what available ingredients can be found in every home and will help bring your equipment into perfect condition. You will learn how to properly prepare the unit for washing, what proportions to follow for preparing cleaning solutions and how to avoid common mistakes that can lead to equipment breakdown.
Preparing the refrigerator for general cleaning
Before you start directly rubbing the shelves and walls, you need to perform a number of preparatory steps. The most common mistake is trying to wash away dirt while the equipment is connected to the network. This is not only unsafe due to the risk of a short circuit when moisture enters, but also ineffective, since warm water on cold surfaces it instantly cools, forming condensation.
The first step should always be to completely disconnect the device from the power supply. After this, you need to remove all products. If you are planning a quick cleaning, you can take the food out to the balcony or other cool place, covering it with a blanket. For general cleaning, it is better to take care of the cold elements in advance or simply wait until the temperature inside the chambers is equal to room temperature.
⚠️ Attention: Never use sharp objects (knives, screwdrivers) to chip ice in the freezer before washing. Damage to the evaporator will lead to a freon leak and costly repairs that cannot be performed on your own.
Removable elements such as glass shelves, plastic containers, vegetable drawers and bottle holders must be removed completely. It is more convenient to wash them separately in a bathtub or large basin, where more active mechanical action and copious rinsing can be used. It is not necessary to free the inner walls of the chamber from unnecessary objects, but access to them should be maximum.
☑️ Action plan before washing
Why soda is the best way to remove grease and odor
Baking soda (sodium bicarbonate) is deservedly considered the king among popular kitchen cleaning products. Its main advantages are a mild abrasive effect, the ability to neutralize acids (sources of unpleasant odors) and absolute safety for food products. Unlike synthetic powders, soda does not scratch glossy plastic and does not leave a toxic film.
To prepare a universal cleaning solution, simply dissolve two tablespoons of powder in a liter of warm water. The resulting mixture is applied to a sponge or soft cloth and wiped all internal surfaces. If there are dried grease stains or traces of berries on the walls, you can make a paste of soda and a small amount of water, apply it to the dirt and leave for 10-15 minutes.
After treating with a soda solution, the surfaces can be easily washed with clean water. It is important to thoroughly rinse the rag several times to remove all residual product. White plaquewhich sometimes remains after the soda has dried can be easily removed by repeated wiping with a damp rag. This method is ideal for annual prevention.
When cleaning with soda, special attention should be paid to the rubber seals on the doors. It is in the folds of rubber that mold most often settles and dirt accumulates. Wipe the seal with a cotton swab dipped in a concentrated soda solution to clean hard-to-reach places without damaging the rubber structure.
Acetic acid: disinfection and mold control
If your goal is not just cleanliness, but complete sterility, then table vinegar (9%) will become an indispensable assistant. An acidic environment is detrimental to most types of bacteria and mold spores that can appear in the refrigerator due to high humidity. In addition, vinegar perfectly dissolves mineral deposits (scale) that can form on the bottom of the chamber or on the condensate tray.
It is not recommended to use vinegar in its pure form, since the pungent odor can take a long time to dissipate, and a high concentration of acid can theoretically damage some types of cheap plastic with prolonged contact. The optimal proportion for the spray is one part vinegar to two parts water. Pour the solution into a spray bottle for ease of application.
Treat the inner walls, ceiling and floor of the chamber with the resulting spray. Leave the product to act for 5-10 minutes, then wipe the surfaces clean. Vinegar is also great for cleaning the outer surface of the refrigerator, especially if you have a model made of stainless steel (although it is better to use special polishes for it, vinegar will help remove greasy fingerprints).
| Remedy | Main action | Solution proportions | Exposure time |
|---|---|---|---|
| Soda | Abrasive, odor removal | 2 tbsp. l. per 1 liter of water | 10-15 min (for stains) |
| Vinegar 9% | Disinfection, descaling | 1:2 with water | 5-10 min |
| Lemon juice | Refreshment, light anti-grease | 1:1 with water | No waiting |
| Ammonia | Removal of persistent odor, grease | 1 tbsp. l. for 1 liter of water | 5 minutes |
After using vinegar, it is recommended to ventilate the room well. Although acetic acid vapors in such concentrations are not dangerous for humans, they can irritate the mucous membranes of the respiratory tract. An open refrigerator door will help you quickly get rid of a specific aroma.
Lemon and essential oils for freshness
Citric acid or natural lemon juice is a great option for those who cannot stand the smell of vinegar or soda. Lemon has natural antiseptic properties and leaves behind a subtle, pleasant citrus aroma that is associated with freshness. This product is especially suitable for washing refrigerators where products with strong odors (fish, garlic, smoked meats) were stored.
To prepare the solution, you can use the juice of half a lemon diluted in a liter of water, or 1 teaspoon of citric acid for the same volume. Wipe all shelves and walls with this mixture. Citric acid also helps fight the yellowness of plastic, returning it to its original snow-white appearance, which often happens with equipment that has been in use for many years.
Essential oils (mint, eucalyptus, orange) can be added to the water for the final rinse. 2-3 drops per liter of water is enough. This will create a thin aromatic film that will neutralize new odors for several days after cleaning. However, you should be careful with the dosage: too concentrated oil can leave greasy stains on the plastic.
⚠️ Attention: Do not use undiluted essential oils or aggressive citrus extracts on rubber seals. Oils can cause the rubber to dry out and crack, which will compromise the seal of the chamber.
The combination of lemon and soda produces an interesting chemical effect (neutralization reaction with effervescence) that helps mechanically lift dirt away from porous surfaces. Pour a little baking soda onto a sponge, add a drop of lemon juice and immediately wipe the problem area. This “fizzy drink” works like a soft scrub.
How to eliminate persistent odors using folk methods
Sometimes, even after a thorough wash, an unpleasant “smell” remains in the refrigerator. It could be the smell of rotten meat, spilled milk, or the specific aroma of new plastic. If a standard washing with soda and vinegar does not help completely, you need to use absorbents - substances that absorb odor molecules from the air.
The most affordable absorbent is activated carbon. Grind 10-15 tablets into powder, scatter into small containers and place on the shelves of a closed refrigerator for a day. Coal has a huge porous surface and effectively absorbs odors. Silica gel (shoe bags) and clay-based cat litter have a similar effect.
Folk wisdom also advises using:
- 🍞 Brown bread: cut the loaf into slices and place on shelves for 2-3 days.
- 🍚 Rice: raw cereal in an open bowl perfectly absorbs moisture and odors.
- ☕ Ground coffee: freshly ground coffee not only absorbs odors, but also flavors the chamber.
- 🧂 Salt: an open pack with a wide neck works as a natural absorbent.
If the smell is caused by liquid that has gotten inside the refrigerator (for example, leaked meat juice into a gap under the shelf), you may have to remove the back panel inside the chamber (if the design allows) and rinse hard-to-reach areas with a syringe with a vinegar solution. In cases where the smell is emitted by foamed insulation (due to a manufacturing defect or aging), folk remedies may be useless, and consultation with a specialist will be required.
What to do if the smell does not go away?
If after thorough washing and using absorbents the smell persists for more than a week, check the drainage hole. It is located on the back wall at the bottom of the camera. A clogged drain is a common cause of a musty smell as water and mucus accumulate there. You can clean it using a special flexible brush or a long wire with cotton wool at the end.
What you should absolutely not use when cleaning
The desire to wash the refrigerator “until it squeaks” sometimes leads to the use of inappropriate products that can irreversibly damage the equipment. The plastic used in modern refrigerators (ABS plastic, polystyrene) is sensitive to a number of chemical compounds. Aggressive solvents can make the plastic cloudy, sticky, or even dissolve its surface layer.
First of all, forget about chlorine-containing products (such as "Whiteness" in its pure form). Chlorine is not only toxic in confined spaces, but it also breaks down the structure of plastic, making it brittle. Also prohibited are acetone, gasoline, paint thinners and any products with abrasive particles (hard powders for cleaning bathtubs). They will leave micro-scratches in which dirt will accumulate even faster.
It is not recommended to use hot water. Sudden changes in temperature can cause cracks in glass shelves or deformation of thin plastic. The water should be warm and comfortable for your hands. Also avoid using steam cleaners inside the chamber - steam can damage electrical contacts and the thermal insulation layer.
Frequently asked questions about cleaning the refrigerator (FAQ)
How often should you wash the inside of the refrigerator?
The optimal frequency of complete defrosting and washing is once every 3-4 months. However, if you notice food spills or foreign odors, cleaning should be done immediately, without waiting for the scheduled date. It is recommended to wipe the external surfaces and handles with a disinfectant weekly.
Is it possible to wash a refrigerator without defrosting it?
It is better to carry out full general cleaning using water only after defrosting. If your model has a No Frost system and there is no ice, you can carry out express cleaning with a damp cloth and soda, being careful not to wet the ventilation holes on the back wall. But the quality of such cleaning will be lower.
How to remove yellowness from the plastic of a refrigerator?
Hydrogen peroxide removes yellowness well (you can use a hair spray containing peroxide or just a pharmacy solution) or a mixture of soda and vinegar. Apply the product, leave for 30-60 minutes (to enhance the effect, you can cover with film) and then rinse. For persistent yellowness, the procedure will have to be repeated several times.
Is it safe to wash the refrigerator with laundry soap?
Yes, ordinary brown laundry soap (72%) is an excellent and safe product. It degreases well and is washed off with water. However, it has a specific odor that can be absorbed into food, so after washing you need to rinse the surfaces very thoroughly and ventilate the chamber. Liquid laundry soap is more convenient in this regard.
What to do if there is mold in the refrigerator?
Mold is dangerous to health. If it is detected, you must immediately remove all products. Wash the camera with a solution of vinegar or hydrogen peroxide. Rubber seals, where mold often hides in micropores, can be treated with alcohol. If mold has penetrated deep into the plastic or insulation, parts may need to be replaced.
