Refrigerators with a system No Frost have long become a standard for modern kitchens, saving users from the need for regular manual defrosting. However, many owners mistakenly believe that such units do not require maintenance of the internal chamber at all. In fact, air circulation inside the chamber contributes to the spread of odors, and over time, an invisible coating of bacteria and mold forms on the walls, which must be removed.
General cleaning refrigerator compartment is necessary not only for aesthetics, but also for food safety. Unlike a drip system, where moisture accumulates at the bottom, in No Frost the water evaporates, but microparticles of food can clog the ventilation holes. It is critically important not to use sharp objects to clean ice on the evaporator, since puncturing the freon tube will lead to expensive repairs. The correct approach to cleaning will extend the life of the compressor and maintain food freshness.
Before taking active steps, it is worth understanding the structure of your model. Some manufacturers, such as LG or Samsungmay have specific requirements for the care of plastic panels. We will consider a universal algorithm that is suitable for most brands, including Indesit, Atlant and Bosch.
Preparing for washing and turning off the power
The first and most important stage is the correct shutdown of the equipment. Many people ignore this step when starting to wash a running unit, which is strictly prohibited. First you need to remove all the products, emptying the shelves and drawers. If it’s winter outside, you can take the contents out to the balcony, otherwise, use cooler bags or simply place the food in a cool place.
After emptying the chambers, you should disconnect the device from the power supply. Unplug the plug from the socket. This will protect you from electric shock when coming into contact with water and will prevent accidental starting of the compressor during cleaning. Leave the doors open for at least 15-20 minutes to allow the inside temperature to reach room temperature.
⚠️ Attention: Do not try to speed up the process of defrosting residual ice by using a hair dryer or hot water directly on the plastic elements. A sharp temperature change can cause deformation of the plastic or cracks in the evaporator housing.
While the equipment is cooling, prepare your equipment. You will need soft sponges, microfiber and water containers. Hard brushes and abrasive scrapers cannot be used - they will leave micro-scratches on the plastic, in which bacteria will subsequently multiply. It is also worth preparing a basin for soaking removable parts.
Dismantling and cleaning removable elements
When the internal space is freed, it is necessary to remove all removable parts: glass shelves, plastic containers, bottle holders and shelves on the door. Glass becomes brittle at low temperatures, so allow shelves to warm to room temperature before washing to prevent them from breaking when exposed to warm water.
Soak plastic parts in warm water and a mild detergent. You can use baking soda to remove stubborn stains from berries or sauces. Rinse each part thoroughly, paying attention to corners and joints where dirt often accumulates. After washing, be sure to wipe the elements dry.
☑️ Checklist for preparing for washing
The inner walls of the chamber where the shelves stood also require attention. Wipe the guides and fastening points. Often it is in these hidden areas that a sticky coating forms. Use a damp cloth, wrung out well, so that excess moisture does not get into the technical openings of the system No Frost.
What to wash inside: choosing safe products
Choosing a cleaning agent - a key point, since foods that can absorb extraneous odors are stored in the refrigerator. Aggressive chemicals with chlorine or strong fragrances will not work here. The ideal solution would be a weak solution of baking soda (1 tablespoon per liter of warm water) or vinegar water in a ratio of 1 to 10.
To remove greasy stains typical for storing meat products or oil, you can use a weak solution of dishwashing detergent. The main thing is to thoroughly rinse the surface with clean water afterward so that no soap film remains. Specialized sprays for refrigerators are also effective, but require checking for the safety of the plastic.
| Type of contamination | Recommended product | What to avoid |
|---|---|---|
| Greasey coating | Soda solution or detergent dishes | Acetone, gasoline |
| Berry stains | Citric acid or vinegar | Chlorine bleaches |
| Mold | Hydrogen peroxide or special agent | Metal brushes |
| Unpleasant odor | Ammonia solution (ventilate!) | Sharp objects |
If you If you use traditional methods, be careful with concentration. Vinegar that is too strong can damage rubber seals, making them hard and brittle. After treating with any product, be sure to wipe the surfaces with clean water and dry with a soft cloth.
Removing odors and fighting mold
Sometimes, even after thorough washing, an unpleasant aroma remains in the chamber. This is a signal that bacteria have penetrated into hard-to-reach places or have been absorbed into the plastic. In such cases, disinfection is required. A hydrogen peroxide solution works well against mold and does not leave an odor after drying.
To prevent the appearance of odors, you can use natural absorbers. Activated charcoal, an open bag of baking soda, or a special odor-absorbing capsule placed on the shelf will help maintain freshness. Change such “filters” once every 1-2 months.
⚠️ Attention: If the smell of rot comes from the drainage hole, simply wiping the walls will not do. It is necessary to clean the condensate drainage channel using a special brush or soft wire to eliminate the source of the problem.
In cases of severe mold contamination, when simple methods do not help, you can use a weak solution of ammonia. However, after such treatment, the refrigerator must be ventilated with the doors open for at least 2-3 hours so that the vapors completely disappear before adding food.
Why does the smell return after a week?
If after cleaning the smell appears again, most likely the source is located outside the visible chamber - in the compressor area or in the air circulation system. A technician is required to disassemble the rear panel.
Cleaning the ventilation and drainage system
The main difference between the system No Frost is the presence of ventilation ducts and holes for condensate drainage. These items must be kept clean. A clogged drain hole causes water to pool at the bottom of the compartment or, worse, leak out under the refrigerator.
Locate the hole on the back wall (usually at the bottom). Clean it carefully with a cotton swab or a special soft brush. You can also use a douche bulb to flush the canal with warm water. Make sure that water flows freely into the pan.
The ventilation grilles located on the back wall of the chamber also need to be cleaned of dust and lint. Use a vacuum cleaner with a narrow attachment at minimum power or a dry, soft brush. Dust on the evaporator impairs heat transfer and makes the compressor work harder.
Drying, assembly and first start-up
After wet cleaning, all surfaces should be perfect dry. Humidity is the enemy of the system No Frostas excess water will instantly turn into an ice crust on the evaporator when turned on. Wipe all corners and joints with paper towels.
Return dry shelves and drawers to their place. Make sure they fit tightly and correctly. Now you can plug in the refrigerator. Let it run empty for 1-2 hours to reach operating temperature. Only after this, load the products.
Regular maintenance of the refrigerator does not take much time, but significantly extends the life of the appliance. If you follow these recommendations, your No Frost will enjoy quiet operation and ideal food preservation for many years.
Is it possible to wash a refrigerator with a steam generator?
Using steam cleaners is risky for electronics and plastic parts. Steam can damage thermal sensors and deform thin plastic, so it is better to limit yourself to wet cleaning.
Frequently asked questions (FAQ)
Is it possible to wash a refrigerator without defrosting it completely?
No, for high-quality cleaning and the safety of electronics, the refrigerator must be unplugged. Washing a working appliance is dangerous and ineffective, since plaque cannot be completely removed, and water can cause a short circuit.
How often should you wash a No Frost refrigerator?
It is recommended to carry out general cleaning once every 3-4 months. If you spill liquid or scatter food, you need to clean up immediately, without waiting for the scheduled date.
How to remove yellow deposits on plastic?
Yellowishness can be easily removed by a paste of soda and water or a weak solution of citric acid. Apply the product to a sponge, gently rub the dirt and rinse thoroughly with clean water.
What to do if after washing the refrigerator makes a loud noise?
Check whether the refrigerator is level and does not touch the walls of the cabinet or furniture. Also make sure that all removable parts (shelves, drawers) are inserted until they click and do not vibrate when the compressor is running.
