Regular cleaning of the refrigerator compartment is not just a matter of aesthetics, but a necessary measure to prevent the growth of bacteria and the appearance of unpleasant odors. Many housewives are wondering how to clean the refrigerator so as not to damage the coating and effectively remove dirt. Incorrectly selected chemistry can spoil plastic, cause corrosion of metal, or leave toxic traces that will subsequently end up in products.
In this article we will look in detail at which cleaning products are suitable for various surfaces, how to safely remove old stains and get rid of ingrained odors. You will learn about proven folk recipes and professional household chemicals that are guaranteed to cope with the task without harm to your equipment.
Keeping the unit clean directly affects the service life of the compressor and the quality of food storage. Greasy deposits on the seals can impair the seal, and crumbs in the drainage hole can cause blockages. Therefore, it is important to know not only what to wash, but also how to organize this process correctly.
Preparing for washing the refrigerator and choosing tools
Before Before you begin the active phase of cleaning, you need to properly prepare the equipment and workspace. First of all, the unit should be completely defrosted, if it is not equipped with a No Frost system, and disconnected from the power supply. This is a critical safety step, as moisture on electrical contacts can cause a short circuit.
For proper cleaning, you will need a set of simple tools. Do not use hard metal brushes or abrasive sponges, which leave micro-scratches. Bacteria will subsequently accumulate in such scratches, and it will be almost impossible to wash them. It is best to prepare soft flannel rags, paper towels and a spray bottle.
Be sure to remove all removable elements: shelves, vegetable drawers, egg trays and containers on the door. It is more convenient to wash them separately in a bathtub or large basin under running water. While they dry, you can easily process the inner walls of the chamber.
☑️ Preparing for washing
Pay special attention temperature conditions water. Do not use boiling water for defrosting or washing, as sudden temperature changes can cause cracks in glass shelves or deformation of plastic parts. The water should be warm, comfortable for your hands.
Folk remedies for safe cleaning
If you prefer environmentally friendly methods or you have run out of household chemicals, time-tested folk remedies will come to the rescue. They are often more effective than aggressive solvents and are absolutely safe for food.
The leader among household cleaners is ordinary baking soda. It has a mild abrasive effect and perfectly neutralizes acidic odors. To prepare the solution, dilute 2 tablespoons of powder in a liter of warm water. This mixture can be used to wipe both the inner walls and the outer surface.
- 🍋 Citric acid or juice: it perfectly dissolves greasy deposits and gives a pleasant fresh aroma. You can use either freshly squeezed juice or a powder solution.
- 🍞 Black bread: an old but effective way to remove the smell of burning or fish. Pieces of bread are laid out in the chamber for several hours.
- ☕ Ground coffee: works as a powerful adsorbent, absorbing foreign aromas. It is enough to place an open bowl of coffee on the shelf.
- 🍶 Vinegar: effective against mold and scale, but requires careful ventilation due to the pungent odor.
Another effective remedy is ammonia alcohol It copes well with grease and disinfects surfaces. However, you need to work with it carefully, be sure to open the windows, since ammonia vapors are toxic when inhaled in high concentrations.
Professional household chemicals for refrigerators
The modern market offers a wide range of specialized products designed to care for kitchen appliances. They often contain antibacterial components and substances that prevent the formation of a film that attracts dust.
When choosing spray or gel pay attention to the labeling “for food surfaces” or “safe for contact with food.” Many all-purpose kitchen products may contain fragrances and chemicals that are not intended for food preservation. Popular brands, such as Domestos, Cif or specialized lines from refrigerator manufacturers (for example, Electrolux, LG), often have suitable options in stock.
⚠️ Attention: Never use chlorine bleaches (type "Whiteness") for washing internal chambers. Chlorine vapor can be absorbed into plastic and rubber seals, after which it will slowly be released, poisoning food.
Foam cleaners are especially convenient for vertical surfaces, since they do not drain immediately and have time to dissolve contaminants. Gel products are better suited for removing stubborn stains, but require more thorough rinsing with water so that there is no sticky layer left.
Removing complex stains: grease, mold and odor
Sometimes standard wiping is not enough, especially if spoiled food has been lying in the refrigerator for a long time or oil has been spilled. In such cases, “heavy artillery” and targeted impact are required.
Greasy stains, especially old ones, respond best to heat and alkali. You can apply a paste of baking soda and water to the stain, leave for 15-20 minutes, and then gently rub with a soft sponge. For external metal surfaces, special polishes for stainless steel are excellent, which remove fingerprints.
If you find mold in the corners or on the seals, you need to act immediately. Mold spores are toxic and spread quickly. The affected area must be treated with a solution of vinegar or hydrogen peroxide. In particularly difficult cases, you can use a weak solution of copper sulfate, but after it the surface must be washed clean several times.
| Type of contamination | Best remedy | Exposure time | Features |
|---|---|---|---|
| Greasy plaque | Soda or dish soap | 10-15 min | Requires warm water |
| Mold | Vinegar or peroxide | 20-30 min | Needs ventilation |
| Yellowness of plastic | Hydrogen peroxide + UV | 2-4 hours | Only for external plastic |
| Scale (drainage) | Citric acid | 30 min | Rinse with a syringe |
For removal odor that does not disappear after washing, use activated carbon. Crush 10-15 tablets, scatter into saucers and leave in a closed refrigerator for a day. Charcoal is a powerful adsorbent that draws odor molecules from the pores of plastic.
Why does plastic turn yellow?
Yellowness on plastic inside the refrigerator often appears due to oxidation of the material under the influence of fats and organic acids contained in products, as well as due to a reaction to certain detergents.
What you should not wash the refrigerator with: list of prohibited products
In order not to turn cleaning into the cause of breakdown of expensive equipment, it is important to know not only what to wash, but also what you should absolutely not do. Modern refrigerators are made of various types of plastic, glass and metal, each of which has its own vulnerability.
Avoid using it in the first place abrasive powders (comifrit, dry pemolux) and hard scrapers. They leave microscopic grooves on the surface. They may not be visible visually, but over time, dirt gets clogged up in them, and it becomes impossible to wash it off. In addition, scratches on plastic make it more fragile.
- 🚫 Acetone and solvents: can melt plastic or remove the glossy layer of coating.
- 🚫 Hot water: above 40-50 degrees can deform thin plastic elements.
- 🚫 Washing powders: they are difficult to wash out and leave a chemical odor, and can also cause allergies upon contact with products.
- 🚫 Melamine sponges: although they are effective, they work like micro-sandpaper and can create a glossy finish matte plastic.
It is also not recommended to use products with a strong odor (for example, for cleaning plumbing fixtures), even if you plan to rinse them thoroughly. The porous structure of some types of plastic can absorb odors, which are then very difficult to get rid of.
Care for seals and the No Frost system
The rubber seal on the door is an element that is most often overlooked, although it is the one that ensures tightness. If it is contaminated with grease or crumbs, the door will not fit tightly, which will lead to ice freezing and increased load on the compressor.
You need to wash the seal with a soft cloth soaked in a soapy solution or a special product for rubber. After washing, it is recommended to wipe it with a dry cloth. Once every six months, you can lubricate the rubber with silicone grease or glycerin so that it does not dry out and crack.
For owners of systems No Frost i Full No Frost the cleanliness of the drainage hole is important. It is located on the back wall inside the camera. If it becomes clogged, condensation will not drain and water or ice will appear inside the refrigerator. You can clean it using a special brush or soft wire, after first pouring in some warm water with citric acid.
⚠️ Attention: When cleaning the back wall inside the refrigerator (where the evaporator is located in No Frost systems), do not use sharp objects to chip ice if it has formed there. You can accidentally puncture the freon circuit, which will lead to expensive repairs.
Do not forget to wipe the external ventilation grilles at the back or bottom of the refrigerator. Dust on them interferes with heat transfer, forcing the motor to work more intensely.
Rules for drying and completing cleaning
The final stage of cleaning is often ignored in the rush to quickly load the products back. However, moisture is the main enemy of a clean refrigerator. The remaining drops of water can become an ideal environment for the development of mold or turn into an ice crust when turned on.
After wet cleaning, be sure to wipe all surfaces dry with a clean cotton or microfiber cloth. Leave the doors open for at least 30-60 minutes to completely ventilate and evaporate moisture from hard-to-reach places. If you used vinegar or chemicals, airing will help remove any remaining odor.
Before turning on the refrigerator, make sure that all removable shelves and drawers are completely dry and in place. Plug in the equipment only after it has reached room temperature, if it has cooled down during washing.
Frequently asked questions (FAQ)
How often should you wash the refrigerator inside?
General cleaning with defrosting is recommended once every 3-4 months. However, you should wipe down shelves and check food for freshness weekly. If accidental contamination occurs (an egg breaks, milk spills), it must be cleaned up immediately.
Is it possible to wash a refrigerator with a steam generator?
Using a steam generator for internal plastic surfaces is not recommended. The high temperature of the steam can deform thin plastic or damage the adhesive joints of the seals. Steam is only suitable for metal external surfaces, and then with caution.
How to remove the smell of fish from the refrigerator?
Adsorbents deal best with the smell of fish: activated carbon, soda, ground coffee or a special odor-absorbing gel. The chamber must first be washed with water with the addition of citric acid or vinegar, as they neutralize the amines contained in fish.
Is it safe to use wet wipes for equipment?
Yes, special wipes for household appliances or alcohol-free hypoallergenic baby wipes can be used for express cleaning of external surfaces and shelves. However, they will not replace a full wash with water if there is serious contamination.
