Hygiene of the refrigerator compartment is not just a matter of aesthetics, but a necessary condition for maintaining the freshness of products and the health of your family. An ideal environment for the growth of bacteria, mold and fungi is created inside the device, especially if spilled liquids or spoiled food are not cleaned up in a timely manner. Regular wet cleaning helps prevent the appearance of unpleasant odors, which are then extremely difficult to get rid of, and extends the life of seals and internal shelves.
Many owners of household appliances make the mistake of using aggressive household chemicals that are not intended for contact with food. The plastic of modern cameras, although it has antibacterial properties, is sensitive to strong solvents, acids and abrasives. An incorrectly selected product can change the structure of the material, make it porous or even toxic, which will subsequently lead to the absorption of odors and spoilage of the products stored there.
In this article we will analyze in detail which substances are truly safe and effective for cleaning internal surfaces. You will learn how to properly prepare equipment for washing, which tools are best to use, and which should be strictly avoided in order not to damage the coating.
Preparation for the washing process
Before you begin the actual washing, you need to perform a number of preparatory actions that will ensure the safety of the process and the efficiency of cleaning. The first and most important step is to completely disconnect the device from the electrical outlet. This safety requirement is dictated not only by the risk of electric shock when water comes into contact with electrical components, but also by the need for defrosting if your model is not equipped with a system No Frost.
After disconnecting, you need to empty the chambers of all products. It is advisable to plan the cleaning in advance so that food supplies are minimal at this time, or prepare cooler bags and coolants for temporary storage. All removable elements - shelves, drawers, egg trays and bottle holders - must be removed. It is more convenient to wash them separately in a bathtub or large basin using warm water.
Let the equipment stand open for at least 30-40 minutes. This time is necessary for the ice crust (if there is one) to begin to melt, and for the temperature inside to equalize with room temperature. Sudden temperature changes when washing with hot water can lead to the appearance of microcracks in plastic or even chips on glass shelves.
☑️ Preparing for washing
While the equipment is cooling, you can inspect the contents and throw away expired products. Often, it is a forgotten piece of cheese or a burst package of yogurt that becomes the source of a persistent, unpleasant odor that cannot be removed by ordinary ventilation.
Folk remedies for safe cleaning
Homemade cleaning recipes are often more effective and safer than store-bought chemicals, since they do not contain chlorine, phosphates and aggressive fragrances. The most popular and affordable remedy is baking soda. It has a mild abrasive effect, perfectly breaks down fat and, most importantly, is a powerful adsorbent that absorbs foreign odors.
To prepare the solution, dilute 2 tablespoons of soda in a liter of warm water. This composition is ideal for washing plastic walls, rubber seals and glass shelves. Soda is not toxic, so even if traces of it remain on surfaces, it will not lead to poisoning. However, it is worth remembering that the soda solution must be thoroughly rinsed off with clean water to avoid the appearance of a whitish coating after drying.
Another time-tested remedy is table vinegar (9%). The acidic environment of vinegar perfectly dissolves limescale that can form from hard water and kills most types of bacteria. The proportions for the solution are simple: one part vinegar to two parts water. It is important to use table vinegar, and not vinegar essence, which has not been previously diluted to the required concentration, since high concentration acid can damage the plastic.
⚠️ Attention: Never mix vinegar and chlorine-containing products (for example, "Whiteness"). As a result of the chemical reaction, chlorine gas is released, which is hazardous to breathing and can cause burns to mucous membranes.
You can also use mustard powder to remove greasy stains and disinfect. It works as a natural emulsifier, binding fats and allowing them to be easily washed off with water. Mustard is especially well suited for washing boxes where meat or butter was stored.
Professional household chemicals
If you prefer ready-made solutions, the market offers a wide range of specialized products for caring for kitchen appliances. When choosing, it is important to pay attention to the “for food surfaces” or “food safe” labeling. Such products undergo stricter control and do not emit harmful vapors at low temperatures.
Sprays based on surfactants (surfactants) do an excellent job of removing old stains and sticky marks from labels. They often contain antibacterial additives, such as silver ions, which prevent germs from reproducing immediately after cleaning. However, after using such sprays, very careful repeated rinsing with water is required.
There are also special wet wipes for household appliances. They are convenient for express cleaning or removing small dirt, but for general cleaning of the entire volume of the refrigerator you will need too many of them, which is not economically viable.
Can you wash with dishwashing detergent?
Yes, you can, but with caution. Dish gels form a rich foam, which is very difficult to completely rinse out of the pores of the plastic. Remaining foam can give food a chemical taste. If you use a gel, take a minimum amount and rinse the surfaces 3-4 times.
When using any “chemicals”, be sure to work in a ventilated area and use rubber gloves to protect the skin of your hands from drying out and irritation.
Comparison of products: effectiveness table
To make it easier for you to choose the best option for Given your situation, we have prepared a comparison table of different cleaning agents. It will help assess their effectiveness against different types of contaminants and safety for materials.
| Medicine | Efficacy against grease | Odor elimination | Safety for plastic | Necessity rinsing |
|---|---|---|---|---|
| Baking soda | Medium | High | Absolutely safe | Required |
| Vinegar 9% | Low | High | Safe (in solution) | Desirable |
| Special. spray | Very high | Medium (masks) | Safe (with rinsing) | Required |
| Laundry soap | High | Low | Safe | Required |
| Citric acid | Low | Average | Safe | Desirable |
As can be seen from the table, there is no universal remedy. Soap or special spray is better for greasy stains, and baking soda or vinegar is better for removing odors and disinfecting. Combining methods often gives the best result.
What absolutely should not be used to clean a refrigerator
The list of prohibited substances is compiled based on the chemical compatibility of materials used in the production of refrigeration equipment. The plastic from which the internal chambers are made can react with aggressive environments, become brittle, turn yellow or lose its antibacterial properties.
First of all, forget about chlorine-containing bleaches ("Belizna", "Domestos" in their pure form). Chlorine not only leaves a persistent, difficult-to-remove odor that permeates all products, but also destroys the structure of polymers. In addition, chlorine vapors in the confined space of a refrigerator are hazardous to health.
Abrasive powders for cleaning bathtubs and stoves are the second enemy of your refrigerator. Small hard particles scratch the smooth surface of the plastic. These microscopic grooves will subsequently become filled with dirt and bacteria, which will be almost impossible to wash off. The surface will become rough and matte.
⚠️ Attention: Do not use acetone, paint thinners or nail polish remover. They can instantly melt the plastic or leave cloudy stains that cannot be removed.
It is also not recommended to use hot water (above 50-60 degrees). Sharp heating can deform thin plastic elements or lead to cracks in the glass of shelves if they are cold.
Washing technology and odor removal
The washing process should follow a certain pattern: from top to bottom. First you wipe the ceiling of the chamber, then the sides, the back wall and lastly the bottom. This is a classic cleaning rule that prevents re-contamination of already washed areas by flowing dirty water.
Use soft sponges (not the hard side) or microfiber rags. Microfiber is especially good because it collects dirt and bacteria into its structure, rather than spreading it across the surface. For hard-to-reach places, corners and panel joints, it is convenient to use a soft toothbrush or cotton swabs.
After cleaning with detergent, be sure to wipe all surfaces with a clean damp cloth to remove chemical residues. Then dry the cameras with paper towels or dry rags. Moisture inside is a risk of mold and ice forming when you first turn it on.
If the smell still remains after cleaning, use natural absorbents. Place plates of activated carbon, ground coffee, rice or citrus zest on the shelves. Leave the refrigerator open for several hours or overnight.
Don't forget to wash the external surfaces: doors, handles and the top of the case. Dust and grease from kitchen fumes also accumulate there.
FAQ: Frequently asked questions
How often should you wash the inside of the refrigerator?
General cleaning with defrosting is recommended once every 3-4 months. However, local cleaning (wiping shelves and removing spills) should be done immediately when soiled. If you notice an unpleasant odor or stickiness on the shelves, this is a signal for immediate cleaning, without waiting for the scheduled date.
Is it possible to wash the refrigerator with a steam generator?
Use a steam generator for internal plastic surfaces not recommended. Too high a steam temperature can deform thin plastic or damage the factory antibacterial coating. Steam can be carefully used only for rubber seals, and then with caution, keeping the nozzle at a distance.
What to do if there is mold in the refrigerator?
Mold is dangerous. If black or green dots are detected, you need to make a solution of vinegar or hydrogen peroxide (3%). Carefully treat the affected areas, let the solution dry (without rinsing), then wipe with clean water. If mold has penetrated deep into the pores of the seal, it may have to be replaced.
How to wash glass shelves to prevent cracking?
Glass shelves cannot be washed with hot water if they have just been taken out of the cold, and vice versa - you cannot put cold glass under a hot stream. Let them warm to room temperature. Use soft sponges without abrasives. A glass cleaner or vinegar solution is ideal.
