Hygiene in the kitchen is not only the cleanliness of work surfaces, but also maintaining order in household appliances. Many housewives and apartment owners pay attention to the internal chamber of the refrigerator, forgetting about the external part, especially in hard-to-reach places. The rear wall of the unit is the area where the maximum amount of dust, pet hair and grease fumes accumulate, which together creates an ideal environment for the growth of bacteria.
Ignoring this area can lead to serious consequences for the operation of the compressor and cooling system. A dust “carpet” on the radiator and condenser tubes significantly impairs heat dissipation, forcing the motor to work with increased load. In this article we will analyze in detail how to properly and safely to wash the back wall of the refrigeratorwithout damaging the technical elements.
Why is regular cleaning of the back panel necessary
The main function of the back of the refrigeration unit is heat exchange. This is where the compressor (often made in the form of a black metal grill or tubes sealed into the wall) is located. During operation, these elements heat up, releasing heat to the environment. When a dense layer of dust mixed with kitchen fat accumulates on the surface, a kind of heat-insulating “coat” is formed. condenser (often made in the form of a black metal grid or tubes sealed into the wall) and a compressor. During operation, these elements heat up, releasing heat to the environment. When a dense layer of dust mixed with kitchen fat accumulates on the surface, a kind of heat-insulating “fur coat” is formed.
This leads to the fact that the refrigerant cannot cool effectively and turn into a liquid state. The compressor is forced to work longer and harder to achieve the set temperature parameters. The result of such operation is not only an increase in electricity bills, but also accelerated wear and tear of expensive components.
⚠️ Attention: Excessive heating of the compressor due to a dirty radiator can lead to melting of the starting relay or even jamming of the motor, which will require complex and expensive repairs.
In addition to technical aspects, there are also sanitary ones factor. Kitchen air is saturated with microparticles of fat that stick to the dust layer. Over time, this mass begins to emit an unpleasant odor, especially when the engine heats up. Regular cleaning allows you to maintain hygiene and prevent the appearance of foreign odors in the kitchen.
Preparation for the cleaning process: safety and tools
Before taking active steps, it is necessary to properly prepare the workplace and the unit itself. The most important rule is to ensure electrical safety. Any manipulations with the back of the refrigerator, where the electrical components are located, should be carried out only after completely disconnecting the device from the network.
You will need to move the refrigerator away from the wall at a sufficient distance so that you can freely walk around it on all sides. Be careful not to jerk the unit sharply, so as not to damage the floor covering or the legs of the refrigerator itself. If the floor is slippery, it is better to place pieces of thick cardboard or special pads under the legs for moving.
For high-quality cleaning, prepare the following set of tools and products:
- 🧹 A vacuum cleaner with a narrow brush attachment to remove the bulk of dry dust.
- 💧 Spray bottle with warm water and a mild detergent (you can use dishwashing detergent).
- 🧽 Soft sponges (one abrasive for stubborn stains, the other soft for plastic) and microfiber rags.
- 🖌️ A brush with long bristles (painting or special for radiators) for cleaning hard-to-reach places between the tubes.
- 🧤 Rubber gloves to protect the skin of your hands from chemicals and dirt.
It is not recommended to use aggressive household chemicals containing chlorine or strong acids, as they can damage the paint and metal elements of the cooling system. It is also strictly forbidden to use metal scrapers or hard brushes, which can scratch the tubes.
Stages of removing dust and dry dirt
The first stage of cleaning is the removal of dry debris. Trying to immediately wash a dusty surface will result in the dust turning into a dirty slurry, which will be extremely difficult to clean due to the dense radiator grille. Therefore, we always start with “dry” cleaning.
Using a vacuum cleaner, carefully go over the entire back surface. Pay special attention to the space between the radiator tubes and the area around the compressor. If your vacuum cleaner has an air blowing function, you can first gently blow out the dust from the depths of the grille and then collect it. However, this must be done carefully so as not to raise a cloud of dust into the air.
☑️ Preparing for washing
A paint brush or a special long brush is ideal for removing dust from hard-to-reach places. Carefully “sweep” contaminants out of the inter-tube space. If the layer of dust is very thick and compressed, you can use compressed air (a canister for cleaning keyboards), but this should only be done in a well-ventilated area or outdoors.
⚠️ Attention: When cleaning with a brush, be careful not to bend the thin radiator tubes or damage electrical wiring that may run near the compressor.
After the bulk of the dust has been removed, you can proceed to wet processing. This will soften the fatty deposits that are often present in the kitchen.
Removing grease deposits and wet cleaning
Grease deposits are the most difficult enemy of cleanliness in the kitchen. It has high adhesion and firmly binds dust, forming a sticky crust. To remove it, ordinary water will not be enough. You will need a warm solution of water with the addition of dishwashing detergent or a specialized kitchen spray.
Apply the cleaning solution to the dirty areas using a spray bottle or a generously moistened sponge. Let the product work for 5-10 minutes. This time is necessary for the chemical components to dissolve the fatty film. Do not allow the product to dry on the surface; add water if necessary.
To clean the radiator grille itself, it is convenient to use a sponge cut in half or a soft brush. The movements should be directed along the tubes to effectively remove dirt from the gaps. If the contamination is very strong, you can use a toothbrush to locally treat stubborn areas.
How to wash off fat if there are no special products?
If you don’t have household chemicals on hand, you can use a solution of baking soda (2 tablespoons per liter of warm water) or laundry soap. These products break down fat well and are safe for metal, but require more thorough rinsing with clean water.
After treatment with detergent, you must thoroughly rinse off all foam and dirt. Use clean water and a microfiber cloth that absorbs moisture well and does not leave lint. Wipe the surface until the flowing water becomes clear.
Cleaning the tray and compressor area
At the bottom of the rear wall of the refrigerator there is often a compressor and a plastic tray for collecting condensate. This area requires special attention, as not only dust, but also water accumulates here, which can lead to mold or rust.
A plastic tray (dropper) is usually mounted above the compressor. In some models it can be removed, in others it is permanently attached. If the tray is removable, carefully remove it, pour out the water and rinse with warm water and disinfectant. Be sure to wipe it dry before installing it back.
The compressor itself (the metal “barrel”) also needs to be wiped, but this must be done extremely carefully. Do not pour water directly onto the motor or electrical contacts. Wipe the compressor housing with a well-wrung out damp cloth. Make sure that the area of the start relay (the plastic box on the side or back of the compressor) is dry.
