Buying new household appliances is always a joyful event that often overshadows the importance of properly preparing the device for operation. Many owners make the mistake of believing that the factory packaging guarantees perfect cleanliness of the internal surfaces. In fact, the process of production, storage and transportation leaves on the walls of the chamber a specific smell of plastic, factory dust and microscopic particles of lubricants.
Ignoring the primary processing stage can lead to the fact that the first portions of products quickly absorb foreign aromas and become unsuitable for consumption. Technical smell - this is not just discomfort, it is a signal of the presence of volatile organic compounds, which are best removed before active use. In addition, wet cleaning allows you to identify possible mechanical defects, scratches or dents that may have appeared during delivery.
In this article we will analyze in detail which products are safe for food surfaces, and which can cause irreparable damage to the internal coating. You will learn about the correct algorithm of actions that will help extend the life of the unit and ensure hygienic safety for your family.
⚠️ Attention: Before starting any manipulations, make sure that the transport bolts and fixing tapes are removed. An attempt to wash the unit without removing the compressor clamps can lead to damage to the system when it is turned on again.
Why is primary treatment necessary
A new refrigerator, just taken out of the box, looks sterile, but this is only a visual illusion. During the assembly process at the factory, various technical liquids are used, and the dust that settles on parts during storage in warehouses contains allergens and bacteria. Primary washing solves the problem of not only visual cleanliness, but also sanitary processing.
Particular attention should be paid to removing the so-called “technical” smell." Plastic used for interior shelves and drawers, as well as door seals, begin to actively release volatile substances upon first contact with air. If not carefully treated, this odor will persist for a long time, transferring to highly absorbent products such as butter, milk or open confectionery.
In addition, a damp cloth helps check the quality of the assembly. When wiping down surfaces, you may find loose parts or sharp plastic edges that could damage product packaging or injure your hands in the future. This is also an excellent time to check the operation of the backlight lamps and the tightness of the door seals.
Preparing for washing: tools and means
Before starting water procedures, it is necessary to prepare an arsenal of cleaning products. The main rule is the safety of materials. The internal surfaces of modern refrigerators are made of impact-resistant plastic and are often covered with an antibacterial layer Anti-Bacteria or Ion Shield. Harsh chemicals can destroy this coating, making the plastic porous and susceptible to mold in the future.
For proper cleaning, you will need soft sponges, microfiber and cotton napkins. Abrasive scrapers, hard brushes and steel wool are strictly prohibited as they leave microscopic scratches. Bacteria will subsequently accumulate in these scratches, which will be extremely difficult to wash.
- 🧼 Laundry soap: classic solid soap without fragrances is an ideal option for degreasing and disinfection.
- 🍋 Citric acid or juice: a natural remedy for eliminating odors and easy disinfection.
- 🌿 Baking soda: a soft abrasive that does an excellent job of removing dirt and neutralizing unpleasant odors.
- 💧 Vinegar solution: a mixture of water and vinegar in a 1:1 ratio effectively kills germs and gives shine.
It is also important to prepare a container with warm water. The water temperature should not exceed 40 degrees Celsius so as not to deform the plastic elements. If you use store-bought products, make sure the packaging is labeled “for food surfaces” or “refrigerator safe.”
What absolutely should not be washed in a new refrigerator
When choosing a cleaning agent, it is easy to make a mistake, guided by the principle “the stronger, the better.” However, in the case of food technology, this approach is disastrous. There are a number of substances that can irreversibly damage the external and internal appearance of the unit, as well as make it hazardous to health.
First of all, avoid chlorine-containing products such as “Whiteness” or various bleaches. Chlorine attacks plastic aggressively, making it yellow and brittle. In addition, chlorine vapors remaining in the confined space of the chamber, upon contact with products, can form toxic compounds.
- 🚫 Acetone and solvents: instantly melt the plastic and destroy the structure of the sealing rubber bands, making them leaky.
- 🚫 Washing powders: contain enzymes and fragrances, which are very are poorly washed and can cause allergies upon contact with food.
- 🚫 Melamine sponges: act as a fine abrasive and can leave microparticles of melamine resin on surfaces, which is unsafe when in contact with products.
- 🚫 Hot water: Boiling water or water with a temperature above 50 degrees can deform thin plastic shelves and drawers.
⚠️ Attention: Do not use dishwashing detergents with strong flavors (lemon, mint, pine). The smell of detergent can be absorbed into the plastic and persistently transferred to food products, distorting their taste.
You should also refrain from using ammonia-based glass sprays to clean internal glass shelves if they have a special coating. Ammonia may react with materials and cause cloudiness. It is best to use specialized products for household appliances or proven folk methods.
Step-by-step instructions for cleaning the refrigerator compartment
The washing process should begin only after the refrigerator is installed in a permanent place and leveled. This is important so that the water used during cleaning does not flow out of the chamber and does not get on the floor or electrical components.
First, remove all removable elements: shelves, vegetable drawers, egg trays, bottle holders. It is more convenient to wash them separately in the bathroom or sink under running water. Wipe the main chamber from top to bottom so that dirty water does not flow through already cleaned areas.
☑️ Checklist for preparing for washing
Start from the ceiling of the refrigerator compartment, then move to the side walls and rear end. Pay special attention to corners and joints where industrial dust may accumulate. Door shelves also require careful treatment, as they often come into contact with product packaging.
| Cleaning area | Recommended product | Tools | Features |
|---|---|---|---|
| Plastic walls | Soda solution (1 tbsp per liter) | Microfiber | Do not rub too hard to avoid damaging the antibacterial layer |
| Glass shelves | Warm water and soap | Sponge | Allow to warm to room temperature before washing |
| Rubber seal | Vinegar solution (1:1) | Cotton swab/rag | Carefully clean the folds without stretching the rubber |
| Vegetable boxes | Laundry soap | Brush with a soft bristles | Rinse thoroughly so that no soap film remains |
After wet cleaning, be sure to wipe all surfaces dry with a clean cotton cloth. Residual moisture may cause ice or mold to form when the compressor is first started. Allow the chamber to dry completely, leaving the door open for 15-20 minutes.
Processing the freezer and No Frost system
The freezer compartment of a new refrigerator also requires attention, although to a lesser extent than the refrigerator compartment. Here it is important to remove any remaining factory grease from the evaporator, if visible, and dust from the system vents No Frost.
In systems with automatic defrosting, air circulates through special channels. If production dust remains in these channels, during the first start it will scatter throughout the chamber and settle on the products. Wipe the accessible parts of the evaporator and the walls of the chamber with a damp, well-wrung cloth.
For freezer drawers, use the same solution as for the main chamber. Plastic becomes more brittle in cold temperatures, so it is important to make sure it is completely dry and free of cracks before freezing. Any crack in the cold can expand and the box will burst.
Features of washing the Fresh Zone
Some models have a “zero temperature” or “freshness” zone. It needs to be wiped especially carefully, since perishable products (meat, fish) are stored there. Use only food-grade disinfectants.
Pay attention to the drainage hole in the freezer (if it is designed to drain melt water). Make sure it is not clogged with packing material or dust. Gently clean it with a cotton swab dipped in warm water.
Eliminating technical odors after washing
Even after thorough washing, the smell of new plastic may persist. This is normal, but you need to get rid of it before loading the products. There are proven methods for absorbing unpleasant odors that work more efficiently than chemical neutralizers.
One of the most effective methods is the use of activated carbon. Mash 10-15 charcoal tablets, pour the powder into a shallow container and place inside a closed refrigerator for a day. Coal is a powerful adsorbent that will absorb odor molecules.
- ☕ Natural coffee: a cup of freshly ground coffee beans or ground coffee perfectly absorbs odors and leaves a light pleasant aroma.
- 🍞 Black bread: a piece of black bread left in an open container on a shelf works like natural coffee absorber.
- 🍋 Citrus zest: lemon, orange or grapefruit peels not only eliminate the smell of plastic, but also disinfect the air.
You can also use a vinegar solution. Dampen a rag in it, wring it out well and wipe the inside walls again, then leave the door open to air for several hours. A draft will help air out volatile substances faster.
⚠️ Attention: Do not use aerosol air fresheners to eliminate odors. Their chemical composition can settle on the walls and, upon contact with food, cause a chemical reaction or change in the taste of the food.
FAQ: Frequently asked questions
Is it possible to wash a new refrigerator with tap water?
Yes, you can, if the water is not too hard. However, for the final rinse it is better to use boiled or filtered water so that there is no limescale left on the walls, which will appear as white spots over time.
Is it necessary to remove the protective film from the internal walls?
There should be no protective films inside the refrigerator. If you find film on internal plastic parts or shelves, be sure to remove it. It is intended only for protection during transportation and interferes with normal heat exchange and hygiene.
How long after washing can you turn on the refrigerator?
You can turn on the unit immediately after you make sure that all surfaces are completely dry. However, it is recommended to load food after 2-4 hours of operation of the empty refrigerator, when it reaches the desired temperature.
What to do if there is a rubber smell left after washing?
The smell of rubber from seals is the most persistent. Wipe the seals with a solution of citric acid or place cotton pads soaked in vanilla or mint essential oil inside. The smell will completely go away after 1-2 weeks of use.
Is it dangerous to use wet wipes for cleaning?
You cannot use ordinary wet wipes for hands or household chemicals because of fragrances and alcohol. There are special antibacterial wipes for household appliances and kitchens - you can use them, but after using them it is still advisable to wipe the surface with water.
