Buying a new refrigerator is always a joyful event, marking the renewal of household appliances in the kitchen. However, immediately after the unit is delivered to the apartment, a natural and important question arises about how to clean the inside of the new refrigerator before turning it on for the first time. Manufacturing processes leave traces: from technical grease and factory dust to the specific smell of new plastic, which can be transferred to products.
Ignoring the primary processing step can lead to even the freshest products quickly absorbing unpleasant aromas or chemicals. Properly selected cleaning products and compliance with washing technology guarantees not only hygiene, but also an extension of the service life of internal coatings. In this article, we will look at which solutions are safe for different types of surfaces and how to avoid common mistakes.
Modern models, whether budget Indesit or premium Liebherr, require a delicate approach. Aggressive chemistry can damage antibacterial coatings or change the color of plastic. Therefore, before taking active steps, you need to clearly understand which components are acceptable and which ones it is better to refrain from for the safety of your family.
Why is primary processing necessary before use
Many owners mistakenly believe that a new device is sterile, since it has just come off the assembly line and was packaged in polyethylene. In fact, inside the chamber there may be microscopic particles of metal shavings, dust from packaging and residues of lubricants used in assembling mechanisms. In addition, the plastic case is often treated with special compounds to protect against scratches during transportation, which are not intended for contact with food.
The second important reason is the elimination of the so-called “factory smell”. New plastics and rubber seals may release volatile organic compounds when first heated. If a thorough wet cleaning is not carried out, these odors can persist for weeks, spoiling the taste of milk, meat and vegetables. Disinfection This stage is also important, since warehouse premises do not always meet sanitary standards for food production.
⚠️ Attention: Never use a new refrigerator to store food until a complete wet cleaning has been carried out and ventilation. Contact of food with factory preservative lubricant can cause food poisoning.
The preparation process also allows you to visually inspect the interior for microcracks or defects that may have formed during delivery. If you notice damage to the plastic now, while the unit is not yet full, it will be easier to fix them or exchange the product under warranty. The cleanliness of the chambers is the foundation for the correct operation of the system No Frost or drip defrosting in the future.
Choosing safe detergents
The main rule when choosing chemicals is the absence of abrasive particles and aggressive solvents. Plastics used in cold stores are sensitive to acetone, gasoline and high concentrations of chlorine bleach. The optimal solution is soft neutral detergents, which are easily washed off with water and do not leave a film.
For those who prefer traditional methods or are prone to allergies, natural acids and alkalis are excellent. Baking soda and acetic acid effectively break down grease and neutralize odors without leaving any toxic residue. It is only important to maintain the correct proportions so as not to create a solution that is too concentrated, which can damage glossy surfaces.
Below is a table that helps compare the effectiveness of different products for different types of stains:
| Type of product | Efficacy against grease | Removal odor | Safety for plastic |
|---|---|---|---|
| Soap solution (laundry soap) | Medium | Low | High |
| Soda solution (2 tbsp per liter) | High | High | High |
| Vinegar water (1:1) | Average | Very high | High |
| Specialized spray for refrigerators | Very high | High | Depends on the brand |
When using specialized sprays, such as Top House or Electrolux, read the label carefully. Some of them require mandatory rinsing with water, while others are positioned as indelible antiseptics. For a new refrigerator, it is better to play it safe and wash off any product with clean water to eliminate the risk of a chemical reaction with the first products put in.
Step-by-step instructions: how to wash correctly
The washing process should be systematic and consistent. First you need to dismantle all removable elements: shelves, vegetable drawers, egg trays and door containers. It is more convenient to wash them separately in a bathtub or large basin using warm water and the selected detergent. This will allow you to clean hard-to-reach places that are hidden under the guides.
After removing the insides, proceed to the main chamber. Movements should be smooth, from top to bottom. Pay special attention to the corners and joints of the panels where dust could accumulate. To wash, use a soft sponge or microfiber cloth, avoiding hard brushes that can leave micro-scratches. Bacteria will subsequently multiply in the scratches.
☑️ Checklist for washing the refrigerator
Don’t forget about the rubber seal on the door. This is a critical element that ensures sealing. Industrial lubricant is often hidden in the folds of the seal. Wipe it carefully without stretching it, using a cotton swab for hard-to-reach places. After treatment, the seal can be lubricated with a special compound or glycerin to maintain elasticity, although for a new device this is usually not required in the first month.
⚠️ Attention: It is strictly forbidden to pour water directly onto the walls of the refrigerator or into the refrigerant outlet area (usually the back wall inside the chamber). Water may flow into the thermal insulation layer or damage electrical contacts, which will lead to breakdown of the compressor or corrosion of the housing.
The final step is thorough rinsing. You need to wash your new refrigerator until the water flowing from the sponge becomes completely transparent and free of foam. Soap residue can crystallize and become sticky, attracting dust. After rinsing, all surfaces are wiped dry with a clean cotton cloth.
Eliminating the specific smell of plastic
Even after thorough washing with soap and water, the smell of new plastic may persist. This is a normal reaction of polymers, but it causes discomfort. If simple airing during the day does not help, you should use natural odor absorbers. They are safe and effective, unlike chemical air fresheners, which can be toxic when in contact with food.
One of the most effective methods is the use of activated carbon. It is enough to crumble 10-15 tablets and scatter them into saucers, placing them on the shelves of a closed refrigerator overnight. Coal has a porous structure that adsorbs volatile odor molecules. Ground coffee or freshly brewed but cooled coffee grounds also do an excellent job.
Extreme methods of fighting odor
If the odor is very persistent, you can wipe the inner walls with a solution of citric acid (1 teaspoon per glass of water). Citric acid not only deodorizes, but also gives a light fresh aroma. However, make sure that the plastic of your refrigerator (especially if it is a cheap model) is resistant to acids by testing the product on an inconspicuous area.
Another proven method is to use black bread or slices of fresh apple. Natural products quickly absorb foreign odors, replacing them with neutral or pleasant odors. Such “filters” need to be changed every 12 hours until the problem disappears completely. It is important not to overexpose the apple so that it does not begin to rot, creating a new source of unpleasant amber.
Features of caring for different types of coatings
Modern refrigerators may have an internal chamber made of different materials. The most common type is durable plastic (ABS or polystyrene), but in mid- and high-end models you can find a metal coating with epoxy enamel or even stainless steel inside. Each material dictates its own rules of care.
Plastic cameras are usually white, very forgiving to detergents, but are afraid of scratches. Metal enamel coatings are more resistant to mechanical stress, but can become dull due to frequent use of acids. Stainless steel inside requires the use of special polishes or alcohol solutions to avoid streaks and (fingerprints).
For glass shelves, which often have aluminum surrounds, it is important not to use products that contain ammonia (as in some window cleaners), as it can react with the metal of the surround, causing it to darken. It is best to use a warm vinegar solution or specialized glass cleaners without ammonia. Thorough drying will prevent limescale from hard water.
What absolutely should not be done when washing
There are a number of misconceptions and bad habits that can turn the joy of a new purchase into a headache. First, never use abrasive powders (Comet, PemoLux) or hard steel wool. They leave microscopic grooves on the plastic, into which dirt will inevitably get clogged, and it will be impossible to remove it from there.
Secondly, avoid using hot water (above 40-45 degrees). Sudden temperature changes or prolonged exposure to heat can deform the thin plastic of the shelves or cause cracks in the places where the guides are attached. A refrigerator is a technique that operates at low temperatures, and the materials inside are selected accordingly.
Thirdly, do not try to speed up the drying process with a hairdryer or heater. Forced drying with hot air can cause materials to expand unevenly and cause cracks. Natural drying with the door open is the safest and most reliable method. It is also not recommended to use chlorine-containing bleaches (“Whiteness”), since
