Modern cooling systems have greatly simplified the life of housewives, eliminating the need for regular manual defrosting, but the question of how to wash the inside of the No Frost refrigerator remains relevant to maintain hygienic cleanliness. Many users mistakenly believe that the absence of ice on the walls means complete sterility, but this is not the case, because bacteria and mold can actively multiply in hard-to-reach places and on shelves.
Improper care No Frost system can lead to the appearance of an unpleasant odor, which over time is absorbed into the products, as well as a decrease in the energy efficiency of the device. In this article, we will analyze in detail all the stages of wet cleaning, explain why aggressive chemicals cannot be used, and give answers to the most frequently asked questions of owners of modern equipment.
Design features of the No Frost system
To understand how to properly wash the inside of a No Frost refrigerator, you must first understand the principle of it work, which is radically different from older models with a drip system. In such devices, the evaporator is hidden behind the back panel, and cold air is circulated forcibly using fans, which eliminates the formation of frost on products.
The main difficulty when cleaning is the presence of a complex system air ducts and drainage holes where dirt and food debris can get in. If you ignore these areas, over time, a bacterial coating will form there, which will be constantly carried by air currents throughout the chamber.
Any damage to the surface can become a hotbed for the development of microbes, which will then be extremely difficult to get rid of without the use of strong chemicals.
How the cycle works defrosting?
In the No Frost system, defrosting occurs automatically: the heating element is turned on several times a day, which melts the frost on a hidden evaporator. The water flows into the drain pan and evaporates naturally. That is why there is no need to wash the evaporator itself, but it is important to monitor the cleanliness of the chamber where the air is supplied.
Preparation for wet cleaning
Before you start washing the No Frost refrigerator inside, you need to carry out thorough preparation, which will take about 15-20 minutes of your time. The first step is to completely empty the chambers of products, sorting them: it is better to take out what can be left at room temperature, and temporarily place perishable goods in an ice bag or in a bowl of cold water.
Next you need to remove all removable elements: shelves, drawers for vegetables, containers on the door and bottle holders. It is more convenient to wash these parts separately in a bathtub or large basin, using warm water and a mild detergent, since in the limited space of the refrigerator it will not be possible to clean them properly.
Be sure to disconnect the device from the power supply by unplugging the plug from the socket to avoid a short circuit if moisture gets on the electrical contacts or sensors. If you plan to use a large amount of water for rinsing, you can carefully pull out the refrigerator, but try not to bend or jerk the hoses sharply if the model is connected to a water supply.
☑️ Preparing for washing
Choosing safe detergents
The choice of chemistry is a critical moment, since The internal surfaces of the refrigerator come into contact with food, and residues of aggressive substances can be hazardous to health. It is strictly forbidden to use chlorine-containing bleaches, acetone, gasoline or hard abrasive powders, which can damage the plastic coating and break the tightness of the seals.
The best choice would be specialized sprays for household appliances or proven folk remedies, such as a solution of baking soda or acetic acid in a weak concentration. These substances effectively remove grease and odors without leaving a toxic film and without requiring repeated rinsing with large amounts of water.
For disinfection, you can use hydrogen peroxide, which is applied to a rag, but after treatment, be sure to wipe the surface with a damp, clean cloth. Don’t forget that even safe products can leave an odor, so the chamber must be completely dry and ventilated before loading food.
Step-by-step instructions: how wash the inside of the Know Frost refrigerator
The washing process should start from the top shelves, gradually moving down so that dirty water does not drip onto already clean surfaces. Dampen a soft sponge or rag in the prepared solution, wring it out thoroughly and wipe the walls, ceiling and floor of the chamber in a circular motion, paying special attention to the corners and joints of the panels.
Pay special attention sealing rubber bands to the doors, as mold and mildew often accumulate in their folds. crumbs. Carefully bend the cuff and wipe the hidden areas with a cotton swab dipped in peroxide or vinegar solution, then wipe dry with a dry cloth.
After treating all surfaces with clean water, rinse the refrigerator to remove any remaining detergent and wipe everything dry with a towel. Do not rush to close the door right away - leave the refrigerator open for 15-20 minutes to completely ventilate moisture and foreign odors.
| Element | What to wash | What to dry |
|---|---|---|
| Plastic walls | Soda solution (1 tbsp per 1 liter) | Microfiber |
| Glass shelves | Glass cleaner or vinegar | Paper towel |
| Rubber seal | Hydrogen peroxide | Dry cotton swab |
| Metal grids | Dishing gel | Dry fabric |
Cleaning the ventilation and drainage system
In systems No Frost it is critical to keep the ventilation holes located on the back wall of the chamber clean, as cold air circulates through them. If these openings become clogged with crumbs or ice crust, cooling efficiency will decrease and the compressor will work overload, which will shorten its service life.
To clean, use a long brush or cotton swab, carefully removing dirt from the air duct grille. Under no circumstances try to pick the holes with a knife or sharp objects, so as not to damage the evaporator elements or sensor wiring hidden under the plastic.
Also check the drainage hole, if it is visible in your model (usually located at the bottom of the rear wall), and clean it with a special flexible wire or a cotton swab. A clogged drain can cause water to accumulate at the bottom of the refrigerator and freeze, forming an ice “coat.”
Elimination of unpleasant odors
Even after thorough washing, an unpleasant odor may persist in the No Frost refrigerator, especially if spoiled food had been stored there for a long time. To neutralize the aroma, you can use natural absorbers, such as activated carbon, coffee beans or an open pack of soda, which are placed on the shelves for a day.
If the odor is very persistent, wipe the internal surfaces with a weak solution of citric acid or place a lemon cut in half on the shelf. It is better not to use chemical air fresheners, as their aroma can mix with the smell of food and spoil the taste of the products.
If the smell is emitted by the plastic itself or rubber parts after a long period of inactivity, airing for 24 hours with the door open in a well-ventilated area will help. Sometimes it is necessary to repeat the washing procedure using enzyme agents that break down organic matter.
Common mistakes when caring for a refrigerator
Many users make typical mistakes that not only do not help clean the refrigerator, but can also damage the equipment. One of the most common mistakes is using hot water to defrost ice or wash, which can lead to cracks in plastic parts due to sudden temperature changes.
Another mistake is ignoring the manufacturer's instructions regarding cleaning products. Some aggressive solvents can make the plastic cloudy or sticky, and no polishes can restore its original appearance.
⚠️ Attention: Never use steam cleaners to clean the interior chambers of a No Frost refrigerator. The high temperature of the steam can melt thin plastic ducts and damage the insulation, and excess moisture will short-circuit the electronics.
Also, do not wash the refrigerator while it is running, or turn it on immediately after washing without allowing it to dry. Moisture in electrical contacts or temperature sensors can cause the controller to malfunction, and the device will no longer correctly maintain the temperature.
Prevention and regular care
So that the question of how to wash the inside of a Know Frost refrigerator does not arise too often, it is important to follow the rules for storing food. All liquids should be covered, and meat and fish should be stored in airtight containers to prevent juices from spreading and odors from spreading.
Once a week, do a quick inspection of the shelves, removing crumbs and stains before they dry out and become a favorable environment for bacteria. Regular light care takes 5 minutes, but eliminates the need for general cleaning with complete defrosting.
Monitor the condition of the door: if it does not close tightly, warm, moist air will enter the chamber, which will lead to increased condensation and quicker contamination. Regularly check the tightness of the seal and, if necessary, adjust the legs of the refrigerator.
⚠️ Attention: Specifications and maintenance requirements may vary depending on the specific model and year of manufacture. Always check the official user manual for your brand of refrigerator before using new cleaning products.
Is it possible to wash a refrigerator without unplugging it?
It is strictly not recommended to wash a running refrigerator, especially by wetting the surfaces excessively. Water may get on electrical contacts, sensors, or vents, causing a short circuit or damage to the electronics. In addition, when the door is open, the running compressor will try to generate cold, consuming excess electricity.
How often should you wash a No Frost system refrigerator?
General cleaning with complete emptying of the chambers is recommended once every 3-4 months. However, it is worth wiping the shelves weekly and checking the expiration dates of products to avoid the appearance of persistent odors and bacteria.
What is the best way to remove greasy stains from plastic?
A solution of laundry soap, baking soda or special dishwashing gels are best suited for removing greasy stains. It is important to thoroughly rinse off any product with clean water so that the chemical does not get on the products.
What to do if a whistle or noise appears after washing?
If noise appears after washing, check whether water has got into the fan area or on the back wall. Allow the refrigerator to dry completely for several hours before turning it on. If the noise persists after drying, it is possible that water has got into the mechanism, and you need to call a technician.
