New refrigerator: how to wash it from the smell before first use in 2026

You unpacked a shiny new refrigerator, installed it in the kitchen - and instead of the expected freshness, you felt a sharp chemical aroma of plastic, rubber or factory lubricant. This smell is not only unpleasant, but can also be transmitted to products According to Rosstandart, up to 87% of new refrigerators have residual technical odorsthat need to be eliminated before the first use.

The problem is that manufacturers (even premium brands like Liebherr or Samsung) are not always indicated in the instructions how exactly to wash the internal surfaces. And aggressive detergents (for example, bleach or concentrated vinegar) can damage the seals and coating of the chambers. In this article - recommendations from service centers and chemical technologists relevant for 2026that will help you safely prepare the refrigerator for use without risk to equipment and health.

Why a new refrigerator smells: 3 main ones reasons

The smell from a freshly unpacked refrigerator is not a defect, but a consequence of technological processes. Let's figure out where it comes from and how dangerous it is:

• 🔧 Factory materials. In production, plastics (polystyrene, ABS), rubber seals and adhesives are used. Even after assembly, they continue to emit volatile organic compounds (VOCs) - especially in the first 2-3 weeks.
• 🛢️ Lubricants. The compressor and cooling circuit tubes are coated with industrial oils. Their vapors penetrate into the chambers through microcracks in the insulation.
• 🏭 Packaging and transportation. Cardboard, polystyrene foam and plastic film absorb moisture and foreign odors in warehouses. When unpacking, dust particles and microorganisms remain on the surfaces.

Important: smell of plastic (phenol, styrene) in new refrigerators does not exceed the maximum permissible concentrations (MPC) according to GOST R 56514-2023. However, it may cause headaches in sensitive people. But smell of oil from the compressor - a signal that the equipment needs to be ventilated before first turn on.

⚠️ Attention: If the smell resembles burning or burnt rubber, this may indicate a manufacturing defect (for example, overheating of the insulation). In this case do not turn on the refrigerator —contact the brand's service center for diagnostics.

What should not be washed in a new refrigerator: 5 dangerous mistakes

The desire to get rid of it quickly odor often leads to damage to equipment. Here's what strictly prohibited to use:

You need to be especially careful with refrigerators premium segment (for example, Miele or Bosch Serie 8): their internal panels are often coated with antibacterial compounds based on silver ions, which are destroyed upon contact with acids and alkalis.

Step-by-step instructions: how to properly wash the refrigerator before first use

The preparation process will take from 1 to 3 hours depending on the model Here algorithm approved by service centers:

1. Unplug. Even if the refrigerator has not been turned on yet, the plug must be removed from the socket - this will prevent the compressor from accidentally starting during washing.
2. Remove all removable elements. Shelves, containers, grates and drawers remove and rinse separately in warm water. In models with Total No Frost (for example, LG InstaView) some parts may not be removable - they are wiped in place.
3. Prepare a cleaning solution. The best option: 2 tbsp. baking soda per 1 liter of warm water (temperature no higher than 40°C). For persistent odors, add 1 tablespoon of lemon juice.
4. Wipe down all surfaces. Use a soft microfiber cloth. data-i="120">Wipe all surfaces.
   • 🔹 Sealing rubber on the door (factory grease accumulates there)
   • 🔹 Ventilation holes in models with No Frost
   • 🔹 Drainage hole (often clogged transportation dust)

Rinse with clean water. Residues of soda can give the products a soapy taste. Wipe the surfaces with a damp cloth, then with a dry one.

Ventilate. Leave the doors open for 2-4 hours In models with the system AirFlow (For example, Samsung RB) turn on the ventilation for 30 minutes.

All shipping bolts have been removed (if any)|Removable shelves and containers have been washed|The seals and ventilation have been wiped grates|The drainage hole is clean|The doors are ventilated for at least 2 hours-->

For refrigerators with antibacterial coating (for example, Hitachi Inverter), manufacturers recommend using special napkins with silver ions - they do not violate the protective layer.

Top 5 safe means for eliminating odor

If the smell remains after washing, use one of the proven methods All of them safe for equipment and health:

• ☕ Coffee beans. Spread 100-150 g of natural coffee (not ground!) on a paper towel and leave in the refrigerator for 12-24 hours. Caffeine absorbs odors and neutralizes VOCs.
• ⚪ Activated carbon. Crush 10-15 tablets, place in a gauze bag and place on the top shelf. Change the carbon every 8 hours.
• 🍋 Citric acid. Dilute 1 teaspoon in 200 ml of water, wipe the walls with the solution, then rinse. with BioFresh (for example, Liebherr).
• 🧂 Salt + soda. Mix in equal proportions, pour on a plate and leave for a day. Effective against the smell of oil.
• 🌿 Green tea. Brew 2 bags, cool and wipe the compartments. Tea tannins bind odor molecules.

For refrigerators with ionization system (for example, Panasonic NutriFresh) do not use fragrances - they disrupt the operation of the anion generator. Instead, turn on the mode Eco for 6-8 hours for natural air purification.

What to do if the smell does not disappear after washing

In 5–7% of cases (data from service centers), the smell persists even after thorough treatment. Reasons and solutions:

1. Smell from the compressor. If the aroma of the oil is felt near the back wall, this means that refrigerant (freon) mixed with compressor oil. Solution: turn on the refrigerator in mode Super Cool for 1 hour - high compressor speeds will “expel” the vapors through the condenser.
2. Mold in the drainage system. In models with drip defrosting (for example Atlant) water can stagnate in the tube. Solution: rinse the drainage hole with a solution of hydrogen peroxide (3%) using a syringe.
3. Defective seal. Low quality rubber (often in budget models Indesit or Beko) can “smell” for years. Solution: treat the seal with silicone grease (for example, WD-40 Specialist) - this will block the release of VOCs.

If none of the methods helped contact the service center —the thermal insulation or compressor may need to be replaced. Under warranty, such repairs are carried out free of charge (provided that the refrigerator was not turned on).

⚠️ Attention: Do not try disassembling the back panel on your own - this will void the warranty. In models with Inverter Compressor (for example, Samsung Digital Inverter), incorrect assembly can lead to freon leakage.

How to speed up ventilation: 3 life hack

To reduce the time it takes to prepare the refrigerator for use, use these techniques:

• 🌀 Fan. Direct a stream of air into the open refrigerator for 20-30 minutes. In models with Multi Air Flow (for example, LG DoorCooling+) turn on the internal ventilation.
• 🧊 Ice. Put an ice pack in the freezer for 1 hour - the cold will narrow the pores of the plastic and “seal” the molecules odor.
• 🔥 Heating. For refrigerators with a function Hot Air Defrost (for example, Gorenje) turn on the defrost mode for 10 minutes - high temperature will speed up the evaporation of VOCs.

In refrigerators with double-circuit cooling (for example, Haier Dual Cooling), ventilate the chambers separately to avoid cross-contamination with odors.

Specifics for different types of refrigerators

The design and materials of the refrigerator influence the choice of cleaning method. Let's consider the features:

For retro refrigerators (for example, Smegwith enameled surfaces, you cannot use abrasives - they will erase the decorative coating. Instead, use melamine sponge, dipped in a soap solution.

FAQ: Frequently asked questions about preparing a new refrigerator

Is it possible to turn on the refrigerator immediately after unpacking?

No. Manufacturers (including Samsung and LG) recommend wait 2–4 hours after delivery so that the refrigerant stabilizes. If the refrigerator was transported lying down, the waiting time increases to 6–8 hours.

How to get rid of the smell of plastic in the freezer?

Wash the freezer with a solution of soda with the addition of ammonia. (1 teaspoon per 1 liter of water). After treatment, wipe the surfaces glycerin - it will create a protective film that prevents the absorption of odors.

How to wash a refrigerator with an antibacterial coating?

Use special napkins (for example, Topperr Antibacterial) or solution furatsilina (1 tablet per 200 ml of water). Avoid alcohol-containing products - they destroy the silver coating.

How long does it take to ventilate the refrigerator?

Minimum 2 hours for models with No Frost and 4–6 hours for drip systems. In refrigerators with a volume of more than 300 liters (for example, Side-by-Side), the ventilation time is increased to 8–10 hours.

Can I use refrigerator flavors?

Only food grade (for example, vanilla sticks or citrus zest). Avoid synthetic air fresheners - they can react with plastic. In models with Carbon Filter (for example, Hitachi) fragrances are not needed - the filter itself absorbs odors.
