General cleaning of refrigeration equipment often becomes a task that is constantly put off until later until accumulated stains and unpleasant odors become critical. However, regular chamber hygiene is necessary not only for aesthetics, but also to extend the life of the unit and food safety. Many owners do not even suspect that old grease on the shelves can significantly worsen heat transfer and cause the compressor to work with overload.
Modern models, whether Liebherr or budget Indesitrequire a delicate approach to cleaning, since use aggressive chemicals can irreversibly damage plastic surfaces and rubber seals. In this article we will analyze proven methods that will allow you to bring your equipment into perfect condition without harming the materials or your health. The correct algorithm of actions will save you time and effort.
Preparing equipment for washing
Before taking active steps to eliminate contamination, it is necessary to properly prepare the unit for the process. The very first and most important rule is complete disconnection from the power supply. You cannot simply pull out the plug while the compressor is still running inside; it is better to wait for it to stop or set the temperature regulator to the “0” or “Off” position 15–20 minutes before starting work.
After de-energizing, the internal space should be emptied of all products. If you are planning a quick cleanup, you can temporarily put the food in bowls with ice or take it out onto the balcony in winter to prevent it from defrosting. All removable elements, such as glass shelves, plastic vegetable containers and drawers, must be removed from the chamber.
⚠️ Attention: Never place cold glass shelves directly under hot water - a sudden temperature change is guaranteed to cause cracks or complete destruction of the tempered glass.
To defrost the freezer, if your model does not have a system No Frost, it will take time. Do not try to speed up the process by chipping the ice with a knife or other sharp objects, as this may damage the evaporator and leak refrigerant. Leave the doors open and wait until the ice begins to melt naturally.
Choosing safe detergents
The household chemicals market offers many specialized sprays for the kitchen, but they may be too aggressive for the interior of the refrigerator. The plastic from which the internal walls and shelves are made has a porous structure and easily absorbs chemical odors, which will subsequently be transferred to the products. Therefore, experts recommend using proven folk remedies or specialized hypoallergenic chemicals.
One of the most effective and safest remedies is ordinary food vinegar. It perfectly dissolves grease deposits, disinfects surfaces and neutralizes unpleasant odors. To prepare the solution, mix water and 9% vinegar in a 1:1 ratio. Baking soda has also proven to work as a mild abrasive for removing stubborn stains.
If you prefer ready-made solutions, pay attention to the “for food surfaces” or “chlorine-free” labeling. Chlorine-containing substances, such as the popular Domestos or Belize, are strictly prohibited for use inside the refrigerator, as their vapors are toxic and can cause corrosion of metal parts.
Step-by-step instructions for cleaning the chamber
The washing process should be carried out sequentially to avoid re-contamination of already clean surfaces. You should always start from the top shelves and gradually work your way down. This rule is dictated by the laws of physics: dirty water and dust particles will flow down, and if you wash the bottom first, you will have to redo the job.
Apply your chosen cleaning solution to a soft sponge or microfiber. Do not use hard brushes or the abrasive sides of sponges, as they will leave micro-scratches on the plastic, in which dirt will subsequently accumulate and multiply bacterial flora. Wipe each shelf thoroughly, paying special attention to the corners and joints.
☑️ Algorithm for washing the refrigerator
After treating all surfaces with clean water, you must thoroughly wipe them dry. Remaining moisture may cause mold or ice to form when turned on. Pay special attention to the drainage hole, which is usually located on the back wall of the chamber - it can be cleaned with a cotton swab or a special brush.
Removing complex dirt and yellowness
After several years of operation, the white plastic inside the refrigerator may acquire an unsightly yellowish tint. This often happens due to the interaction of plastic with fats contained in food, or due to the oxidation of the material over time. Proven methods will help restore the original whiteness.
To remove yellowness, you can use a paste of soda and water. Apply the mixture to the yellowed areas, leave for 10-15 minutes, and then rinse gently. Another effective method involves using toothpaste (toothpaste) without colored granules - it acts as a mild whitening polish. Apply the paste to a sponge and work the surface in a circular motion.
If there are traces of berry juice, coffee or tomato paste on the shelves that cannot be wiped off in the usual way, try using vegetable oil. Apply a few drops of oil to a cotton pad and wipe the stain, then degrease the surface with soapy water. Oil perfectly dissolves organic dyes.
⚠️ Attention: Do not use acetone, gasoline or solvents to remove stains, as they can melt the plastic and make it sticky, after which it will be impossible to restore the surface.
Fighting unpleasant odors
Even after thorough washing, the inside may persist a specific smell, especially if spoiled food has been in the refrigerator for a long time. Simple ventilation does not always help, so it is necessary to use adsorbents - substances that absorb odors.
The most affordable and effective adsorbent is activated carbon. Crush 10–15 tablets and scatter the powder into saucers, placing them on the refrigerator shelves for a day. Freshly ground coffee or soda poured into an open container also does an excellent job.
To prevent the appearance of odors, you can use natural flavors. A lemon cut in half or a cotton pad soaked in vanilla extract will give your camera a fresh scent. However, you should not overuse strong odors so that they do not interrupt the natural aroma of the products.
Comparison of cleaning methods: effectiveness table
To make it easier for you to choose the right product for a specific task, we have prepared a comparison table. It will help evaluate the effectiveness of various methods depending on the type of pollution.
| Type of pollution | Recommended product | Exposure time | Safety for plastic |
|---|---|---|---|
| Grease deposits | Vinegar solution (1:1) | 5-10 minutes | High |
| Dried juice stains | Soda slurry | 15 minutes | High |
| Yellowness of plastic | Toothpaste / Peroxide | 20-30 minutes | Medium |
| Mold in the corners | Hydrogen peroxide | No waiting | High |
Care for the No Frost and ventilation system
Owners of modern models with the system No Frost often mistakenly believe that their refrigerators do not need to be washed at all. This is a misconception: although ice does not form in them, dust and bacteria circulate through the ventilation system, settling on the evaporator and fans. This can lead to the appearance of an extraneous hum and deterioration of cooling.
Once every six months, it is recommended to remove the back panel inside the refrigerator compartment (if the design allows) and carefully vacuum the accessible elements of the ventilation system. It is also necessary to clean the drainage channel through which condensate flows into the tray above the compressor. A blockage in this channel is a common cause of puddles appearing under the refrigerator.
How to clean the drainage hole?
To clean it, use a special flexible brush or a piece of soft wire wrapped in cotton wool. Carefully insert the tool into the hole on the back wall, making rotational movements. After mechanical cleaning, pour 50 ml of warm water into it to check the permeability.
Do not forget to wipe the temperature sensors if they protrude into the chamber. A dirty sensor can transmit incorrect data to the control board, causing the refrigerator to operate incorrectly, either undercooling or freezing food.
Frequent cleaning mistakes
The desire to wash the refrigerator “until it squeaks” often leads to mistakes that can cost expensive repairs. One of the most common mistakes is using steam cleaners. Hot steam under pressure can deform the thin plastic of the shelves and damage the adhesive that holds the seals.
Also, do not wash the refrigerator while it is plugged in, even if you do it very quickly. Moisture on the electrical contacts or control board may cause a short circuit. Always follow the rule: first turn off completely, then wash.
⚠️ Attention: If you use glass cleaning sprays, make sure they do not contain ammonia. Ammonia destroys the structure of the plastic, making it cloudy and brittle over time.
Ignoring the external cleanliness of the condenser (the grill at the back of the refrigerator) is also a mistake. A dust “carpet” on the radiator impairs heat transfer, causing the engine to wear out. Wipe the back panel with a dry cloth or vacuum it during each general cleaning.
Frequently asked questions (FAQ)
Is it possible to wash the inside of the refrigerator with dishwashing detergent?
Using regular dishwashing detergent is possible, but highly undesirable. It forms a rich foam, which is very difficult to completely wash off from plastic surfaces. Residues may cause a chemical reaction with food and create an unpleasant aftertaste. If there is no other way out, use a minimal amount of product and thoroughly wipe the surface with a damp cloth 3-4 times.
How often should you carry out general cleaning of the refrigerator?
The optimal frequency of complete defrosting and washing depends on the model. Refrigerators with manual defrosting require attention every 3-4 months. Models with the system No Frost it is enough to wash them once every 6-8 months, unless emergency situations have occurred (for example, leaked milk or a burst can of juice).
How to remove traces of tape or stickers from a shelf?
To remove sticky traces, use vegetable oil, alcohol or a special product "Antiscotch". Apply the substance to a cotton pad, apply it to the sticker for a couple of minutes to soften the glue, and carefully wipe it off. Do not use a blade to avoid scratching the plastic.
Is melamine sponge safe to use?
Melamine sponge is an excellent abrasive, but you need to use it with caution on food surfaces inside the refrigerator. After cleaning with melamine, it is necessary to rinse the surface very thoroughly with water, since microparticles of melamine resin should not enter the body. For food areas, it is better to choose safer alternatives.
What to do if the smell of fish or meat remains after washing?
If the smell does not go away after regular washing, prepare a saturated solution of salt and water and wipe all surfaces with it. Then place Activated charcoal (activated carbon) or special odor absorbers for refrigerators inside. Keep the door open for at least 24 hours in a ventilated room.
