Modern refrigerator is not just a metal box with a motor, but a complex system, requiring regular maintenance. Many owners mistakenly believe that low temperatures automatically kill bacteria, but this is not true. Cold only slows down the proliferation of microorganisms, and some types of mold and psychrophilic bacteria feel great even at sub-zero temperatures.
That is why the question of how to properly wash the inside of a refrigerator remains relevant for everyone who cares about the health of the family. Regular cleaning helps extend the life of the unit, saves energy and prevents unpleasant odors. In this article, we will analyze safe methods for removing contaminants and draw up an action plan for perfect cleanliness.
It is important to understand that the approach to cleaning depends on the type of coating on the internal walls. Glossy plastic, matte surfaces and glass shelves require different care products. The use of aggressive chemicals can lead to the appearance of microcracks in which bacteria will subsequently accumulate.
Preparation for the washing process: safety and defrosting
Before starting any manipulations, it is necessary to ensure the safety of the electrical appliance. Disconnection from the network is the first and mandatory action. Even if you only plan to wipe the shelves, the risk of moisture getting on the electrical contacts or the compressor is too great to neglect.
The next stage is complete defrosting. Even if you have a model with a No Frost system, condensation and ice in the evaporator can interfere with quality cleaning. Leave the doors open for at least 2-3 hours, preferably overnight. This will allow the ice to melt naturally.
⚠️ Attention: Never use a knife or other sharp objects to chip ice. Damage to the evaporator will lead to a refrigerant leak and costly repairs, which are often not economically feasible.
While the unit is defrosting, remove all food. Inspect the contents: throw away spoiled items and use products with expiration dates first. This is the ideal time to wipe the packages free of dust and sticky marks before returning them.
Choice of safe detergents
The household chemicals market offers many sprays, but it is often more effective and safer to use proven ones. folk remedies. They do not leave toxic traces and do not require thorough rinsing with large amounts of water, which is critical for the internal chamber.
One of the best solutions is the usual one baking soda. It perfectly absorbs odors and works as a soft abrasive without scratching surfaces. Dissolve 2 tablespoons of powder in a liter of warm water, and the universal cleaner is ready.
Ideal for disinfecting and removing greasy stains acetic acid. Mix table vinegar with water in a 1:2 ratio. This product kills up to 80% of types of bacteria and mold, while being completely safe for food.
Strictly avoid using chlorine-containing products, acetone, gasoline or abrasive powders. Chlorine can damage rubber seals, making them hard and brittle, and abrasives will leave scratches on the plastic, which will become an ideal habitat for microbes.
Step-by-step instructions: how to wash the inner chambers
You should start washing from the top shelves, gradually moving down. This sequence is due to the laws of physics: dirty water and contaminants flow down, and you do not have to re-wipe already clean areas.
First, wipe the inner walls with a soft sponge soaked in the selected solution. Pay special attention to the corners and joints, where it most often forms mold. If you find black dots, treat them with a cotton swab dipped in hydrogen peroxide or undiluted vinegar.
☑️ Algorithm for washing the camera
After treating all surfaces, thoroughly rinse off the cleaning agent remedy. Use clean water and a well-wrung out cloth. Remains of the cleaning solution can be absorbed into the plastic and subsequently change the taste of stored products.
| Type of contamination | Recommended product | Tools |
|---|---|---|
| Grease stains | Household solution soap | Soft sponge |
| Mold | Table vinegar (9%) | Cotton pad |
| Old stains | Paste of soda and water | Toothbrush |
| Yellowness of plastic | Lemon juice | Microfiber |
The final stage will be drying. Leave the doors open for another 30-40 minutes after wet cleaning. This will allow residual moisture to evaporate from hard-to-reach places and prevent the appearance of a musty smell.
Cleaning removable elements: shelves and drawers
Glass shelves and plastic drawers are more convenient to wash separately, in a bathtub or large basin. This allows you to inspect them from all sides and thoroughly clean the ends and fastenings. However, there is an important nuance related to the temperature regime.
Glass that has been in the cold cannot be immediately placed under hot water. A sudden temperature change tempered glass may burst. Let the shelves warm up to room temperature or wash them with lukewarm water.
How to remove odors from plastic boxes?
Plastic tends to absorb odors. To get rid of them, soak the boxes in a solution of water and activated carbon (10 tablets per 5 liters) for several hours. Wiping the inner surface with a slice of black bread or a cotton pad with ammonia also helps.
For plastic containers, use soft sponges. Hard brushes will leave micro-scratches in which dirt will accumulate, and it will be much more difficult to wash them next time. If there is a sticky residue left on the plastic from berries or jam, use vegetable oil to dissolve it, and then wash it off with a soap solution.
Care for seals and vents
Rubber seal on the door is the weak point of any refrigerator. Dirt, crumbs and moisture often accumulate in the folds of rubber, which leads to the appearance of black mold. If the seal does not fit tightly, cold air will escape, causing the compressor to wear out.
Wipe the rubber with a vinegar solution or a special product for caring for rubber products. You can use a toothbrush to clean hard-to-reach wrinkles. After cleaning, lubricate the seal with glycerin or silicone grease to maintain its elasticity and prevent cracking.
⚠️ Attention: When cleaning the back wall inside the camera, be careful with the ventilation holes. Do not fill them with water or push a rag inside to avoid damaging the air circulation system.
Also check the condensate drainage channels. If you notice water at the bottom of your refrigerator, the drain hole may be clogged. Carefully clean it with a special brush or soft wire, after turning off the device.
Fighting odors and final drying
Even after thorough washing, sometimes a specific smell remains. This is normal, as the odor molecules may have penetrated deep into the structure of the plastic. To neutralize them, use natural absorbents.
Place open containers with activated carbon, ground coffee, soda or citrus zest on the shelves. These substances perfectly absorb foreign odors. You can also use special odor absorbers, which are sold in hardware stores.
Before loading food back, make sure that the refrigerator is completely dry and warmed up to operating temperature. Turning on a unit with wet walls can lead to the formation of an ice crust and increased load on the system.
Is it possible to wash a refrigerator without unplugging it?
Technically, it is possible if you very quickly wipe the shelves with a well-wrung out cloth. However, manufacturers categorically do not recommend doing this due to the risk of a short circuit if water gets on the contacts or thermostat. It is safer to turn off the power to the appliance.
How often should you wash the refrigerator?
It is recommended to carry out general cleaning with defrosting once every 3-4 months. Wiping shelves and inspecting products should be done weekly or as they become dirty. This will prevent the formation of persistent stains and odors.
What should not be used to clean the inside of the refrigerator?
It is prohibited to use boiling water, abrasive powders, chlorine-containing bleaches, solvents (acetone, gasoline) and hard metal brushes. These products destroy plastic, damage the coating and can be toxic to food.
What to do if a chemical smell appears after washing?
It is necessary to re-wipe all surfaces with clean water, adding lemon juice or a few drops of essential oil. Then leave the refrigerator open to air for several hours, placing a bowl of baking soda inside.
