Modern systems No Frost have saved us from the need to deal with ice coats and chip away at frostbite on a weekly basis with an axe, but this does not mean that the equipment does not need to be maintained. Many owners mistakenly believe that the absence of visible ice guarantees sterility, forgetting that air circulation only spreads bacteria and odors throughout all shelves. Regular hygienic treatment is necessary to prevent the appearance of mold in hidden channels and extend the life of the compressor.
The cleaning process of units with automatic defrosting has its own technological nuances, ignoring which can lead to breakdown of sensors or failure of fans. Unlike older models, you cannot use aggressive chemicals here or pour water directly onto the back wall. Proper care requires a delicate approach to plastic elements and knowledge of the location of drainage holes.
In this article we will look at the best way to wash internal surfaces, how often you need to do general cleaning and what products really effective against bacteria. You will learn why LG refrigerator or Bosch can emit an unpleasant odor even when working properly and how to fix this problem without calling a technician. Following simple rules will help maintain food freshness and the neat appearance of your kitchen.
Preparing for washing: safety and defrosting
The first and most important step is to completely disconnect the appliance from the power supply. Although the system No Frost assumes operation without ice formation, there is still a small amount of moisture in the evaporator that must drain. Unplug the plug from the socket and let the equipment stand turned off for at least 30-40 minutes so that the temperature inside the chambers becomes equal to room temperature.
While the unit is cooling, it is necessary to free up the internal space. Remove all products, check their condition and discard spoiled items. It is better to remove glass shelves and plastic containers immediately and take them to the bathroom for a separate wash under running water using your usual dish soap.
⚠️ Attention: Never use a knife, screwdriver or other sharp objects to remove dirt or ice. The plastic in models Indesit and Atlant is quite fragile, and one awkward movement can break through the channels of the cooling system, which will lead to freon leakage and expensive repairs.
Pay special attention to the drainage hole, which is usually located on the back wall of the refrigerator compartment. It is through it that the condensate flows into a special container above the compressor. If this channel is clogged with crumbs or mucus, water will begin to accumulate inside, which will provoke the growth of bacteria. You can clean it using a special brush or a regular cotton swab dipped in warm water.
☑️ Checklist for preparing for washing
Choice of detergents: chemistry or traditional methods
The choice of cleaning agent directly affects the durability of plastic elements and the safety of stored products. Aggressive solvents, acetone or chlorine-containing powders can damage the structure of the plastic, making it cloudy or brittle. In addition, strong chemical odors can be absorbed into the seals and bother you for a long time when opening the door.
Gentle homemade compounds are great for daily or routine cleaning. A solution of baking soda (one tablespoon per liter of warm water) effectively removes grease stains and neutralizes unpleasant odors. Acetic acid in low concentration helps fight scale and disinfects surfaces, killing most types of bacteria.
If you prefer ready-made solutions, choose specialized sprays marked “for refrigerators” or “antibacterial.” They generally do not require rinsing and are safe for food contact once dry. Avoid using abrasive sponges that leave micro-scratches - dirt will accumulate in them much faster.
| Type of product | Efficacy | Safety for plastic | Odor removal |
|---|---|---|---|
| Soda solution | Medium | High | High |
| Vinegar 3-5% | High | Average | Average |
| Special. spray | High | High | Medium |
| Soap solution | Low | High | Low |
Technology for washing internal chambers
The washing process should start from the top, gradually working your way down. This will avoid re-contamination of already clean surfaces with dirty water flowing down. Thoroughly wipe the ceiling of the chamber, side walls and shelves, paying special attention to the corners where dust and mold deposits most often accumulate.
Door seals require special attention. The rubber cuff is an ideal place for the growth of microorganisms due to constant humidity and contact with food. Carefully bend the folds of rubber and wipe them with a cotton swab dipped in a disinfectant solution. If the cutting has become harsh, you can lubricate it with a small amount of glycerin to restore elasticity.
After wet processing, all surfaces must be wiped dry with a clean microfiber or cotton cloth. Remaining moisture in the system No Frost can freeze when turned on, putting extra strain on the fans, or causing puddles on the kitchen floor. Make sure that the drainage hole is free and dry.
⚠️ Attention: It is strictly forbidden to pour water into the chamber using a stream from a bottle or ladle. Liquid may get on electrical contacts, light bulbs, or air ducts, causing short circuits or corrosion of metal parts.
Wash interior glass shelves and plastic drawers separately in the sink. To remove stubborn berry or sauce stains, use a soft sponge. After washing, let the parts dry completely at room temperature before putting them back.
The secret to keeping drawers clean
Soak plastic containers in warm water with dishwasher tablets for 15 minutes. This will help dissolve grease deposits and remove yellowness, which is difficult to wipe off with a sponge.
Maintenance of the external surface and ventilation grilles
The appearance of the equipment also requires maintenance, especially if the refrigerator is in a kitchen with a gas stove, where grease hangs in the air. For stainless steel cases, use special polishes that create a protective film and hide fingerprints. Movements with the sponge should be strictly along the fibers of the metal so as not to leave unsightly scratches.
Painted metal or plastic surfaces can be simply wiped with a damp cloth and a drop of mild detergent. Avoid using scrapers to remove dried-on stains - it is better to soak the dirt with warm water. Pay special attention to the handles, as they are the main source of bacteria.
An important element of the system No Frost are the ventilation grilles located inside the chambers and often on the rear outer wall. Dust settling on them impairs heat transfer and makes the compressor work harder. Gently vacuum the grates with a soft bristle attachment or blow them with compressed air.
Elimination of unpleasant odors
The appearance of a musty or specific odor in the refrigerator No Frost often indicates that bacteria have settled in hard-to-reach places in the air circulation system. Before using odor absorbers, it is necessary to find and eliminate the source - spoiled product in the seal or stagnant water in the pan.
If the smell persists after thorough washing, try using natural absorbents. Activated carbon, ground coffee, baking soda in an open container, or special absorbent balls effectively neutralize odors. Place them on the shelves for 24-48 hours with the refrigerator turned off but open.
In cases where the smell is very persistent and resembles the smell of sewage or rot, the problem may lie in a clogged drain tube or condensate pan, which is located above the compressor at the back. To clean the tube, you can use a long brush or a medical bulb, rinsing the channel with warm water and a disinfectant.
⚠️ Attention: If after all the cleaning procedures the unpleasant odor persists and is accompanied by a strange hum or ineffective cooling, this may indicate a technical malfunction, for example, a violation of the tightness of the circuit. In this case, diagnostics by a specialist is necessary.
To prevent the appearance of aromas in the future, do not place hot foods in the chamber and always cover the food with a lid or film. Regular inventory revision will help avoid a situation where a forgotten vegetable begins to rot in the far corner of the drawer.
Maintenance frequency and typical errors
The optimal frequency of general cleaning of a refrigerator with a system No Frost is once every 3-4 months. However, during intensive use or spillage of liquids, the procedure should be carried out as soon as it becomes dirty. Regularly wiping your shelves with a damp cloth once a week will help keep them clean without much effort.
One of the most common mistakes is using hot water to defrost or wash. Sudden temperature changes can cause deformation of plastic parts and cracks in glass. All procedures should be carried out at a water temperature no higher than 30-40 degrees.
Also, owners often forget to ventilate the chamber after washing. Leave the doors open for 1-2 hours so that any remaining moisture completely evaporates and the smell of the cleaning product disappears. Only after this can you load food and turn on the appliance.
Ignoring cleaning the external radiator grille (if there is one at the back) or the space around the compressor also reduces the efficiency of the equipment. A dust “carpet” on the heat exchanger causes the motor to overheat, which reduces its service life.
Is it possible to wash a refrigerator without unplugging it?
Theoretically, a quick wipe of the shelves can be done with the compressor running, but a full-fledged wash involving removing drawers and using water is strictly not recommended. This is dangerous for electrics and can lead to false readings from temperature sensors.
How often do you need to defrost a No Frost refrigerator?
The system No Frost does not require regular defrosting to remove ice, as it does it automatically. However, once a year it is recommended to carry out a complete defrost for 24 hours for hygienic treatment and rest of the compressor.
What cannot be used to wash plastic parts of the refrigerator?
It is prohibited to use abrasive powders, pure chlorine, solvents (acetone, gasoline) and hard metal brushes. These substances destroy the structure of the plastic, making it brittle and porous.
What to do if the refrigerator does not turn on after washing?
If after cleaning the equipment does not respond to turning on, check whether the contacts are completely dry and whether water has entered the connectors. Let the device remain turned off for a few more hours. If the problem persists, call a technician.
Why does the refrigerator smell like plastic after purchase?
A new plastic smell is normal. It disappears in 2-3 days. Washing the internal surfaces with a weak soda solution and ventilating with the doors open will help speed up the process.
