A new refrigerator is not only the joy of a new thing, but also an unpleasant surprise in the form of a persistent chemical smell. Even premium models from Samsung, LG or Bosch often smell like plastic, polyurethane foam and factory lubricants in the first weeks after purchase. This aroma is not just annoying - it can penetrate into products, spoil their taste and even cause headaches in sensitive people.
The reason lies in the materials: modern refrigerators are assembled from ABS plastic, polyurethane foam (for thermal insulation) and synthetic seals. All of these components emit volatile organic compounds, especially intensely in the first days after unpacking. Fortunately, you can get rid of the smell without special means, using available methods and the correct sequence of actions.
This article contains proven methods that work for refrigerators of any brand: from budget ones Atlant i Indesit to premium Liebherr i Miele. We’ll also look at why some “folk” advice (like vinegar or bleach) can harm your equipment.
Why does a new refrigerator smell and is it dangerous?
The smell of a new refrigerator is not a defect, but a normal phenomenon associated with emission of volatile organic compounds (VOCs). Main sources:
- 🔹 Polyurethane foam —thermal insulating layer between the walls. Releases formaldehyde and other substances, especially when heated (for example, if the refrigerator was left in the sun during transportation).
- 🔹 ABS plastic is the material of the shelves, drawers and body. Exudes a characteristic “chemical” aroma of styrene.
- 🔹 Lubricants and adhesives —used when assembling the compressor and seals. May smell like machine oil or rubber.
- 🔹 Packaging materials - foam, plastic film and cardboard absorb factory odors and release them back.
According to data Rospotrebnadzor, the concentration of VOCs in new refrigerators usually does not exceed the maximum permissible standards (MAC) for residential premises. However, for people with allergies or asthma, even a faint odor can cause mucous membrane irritation, coughing, or dizziness. In addition, if the source is not eliminated, the aroma may persist up to 6–12 months —especially in models with a system No Frostwhere air circulation distributes the smell throughout all compartments.
⚠️ Attention: If the smell is pungent, reminiscent of burning or ammonia, this may indicate refrigerant leakage (freon). In this case, immediately unplug the refrigerator and contact a service center. Freon in high concentrations is dangerous to health!
Preparation of the refrigerator: what to do before turning it on for the first time
Many users turn on the refrigerator immediately after delivery - and in vain. Proper preparation reduces the time it takes for the odor to dissipate by 2–3 times. Follow this algorithm:
- Unpack the refrigerator completely. Remove all stickers, protective films, foam inserts and cardboard. Pay special attention to the back wall - pieces of packaging often remain there.
- Wipe all surfaces. Use a soft cloth soaked in warm water with baking soda (1 tablespoon per 1 liter of water). This will remove factory dust and some chemical compounds from the plastic.
- Remove and wash the removable elements. Remove shelves, drawers, door balconies and grilles and wash separately with soapy water. For persistent odors, dishwashing detergent is suitable (for example, Fairy or Ecover).
- Check the drainage hole. It is located on the back wall of the refrigerator compartment (usually under the bottom shelf). Clean it with a cotton swab - foam particles and dust.
After preparation, leave the refrigerator with the doors open for 12-24 hours in a ventilated room. If the weather is warm outside (above +15°C), you can take it out to the balcony - this will speed up weathering.
Top 5 folk remedies for plastic smell
If the smell remains after airing, use proven home methods. They are safe for equipment and do not require the purchase of expensive products.
| Remedy | How to use | Time actions | Pros | Cons |
|---|---|---|---|---|
| Activated carbon | Place 10-15 tablets on a saucer in each compartment. Replace every 2-3 days. | 3–7 days | Absorbs chemical compounds, leaves no odor | Needs to be changed frequently |
| Baking soda | Sprinkle baking soda on a baking sheet or in an open container (2-3 tbsp. l. per camera). | 5–10 days | Neutralizes acidic odors, safe for products | Less effective against formaldehyde |
| Lemon or orange | Cut cut the citrus in half and put it on the shelves. Or use the zest. | 2-4 days | Pleasant aroma, antibacterial effect | May leave sticky marks |
| Coffee (beans or grounds) | Spread freshly ground coffee on a paper sheet. | 3–5 days | Absorbs odors, leaves a light coffee aroma | May stain plastic on contact |
| Vinegar (9%) | Wipe the walls with a solution (1:1 with water), then ventilate. | 1–2 days | Kills bacteria, quickly eliminates odor | Pungent odor, can damage rubber seals |
Important: Do not use vinegar for models with air ionizers (for example, Panasonic NR-B or Sharp SJ-X). Acid can damage the antibacterial coating of the internal walls.

Special odor absorbers: what to choose
If traditional methods do not help, it’s time for professional products. They are divided into three types:
- 🧊 Absorbents based on zeolite or activated carbon. Examples: Bork Z100, Topperr 3106. Absorbs odors at the molecular level and lasts up to 6 months.
- 🌿 Ionizers and ozonizers. Devices like Xiaomi Viomi Air Purifier or Philips AC4236 generate ions neutralize VOCs. Suitable for refrigerators with system
No Frost. - 🍃 Gelium and granular absorbers. For example, Fresh Box or Fridge FreshContain natural enzymes that decompose organic compounds.
When choosing, pay attention to:
- 🔄 Service life — from 1 to 12 months.
- 📦 Coverage volume —for refrigerators up to 200 liters, a compact absorber is suitable, for Side-by-Side needs powerful models.
- 🚫 Compatibility with products —some products (for example, with flavorings) can transfer their smell to food.
⚠️ Attention: Ozonizers (Atmos Vita, EcoQuest) are effective, but they cannot be used in the presence of people - ozone in high concentrations is toxic. Treat the refrigerator 1-2 hours before use, then ventilate.
How to check the authenticity of the absorber
The composition must be indicated on the package (for example, “zeolite 80%, activated carbon 20%”).
Original products have a certificate of conformity (can be checked using the QR code).
Fakes often smell like chemicals themselves - this is a sign of low-quality flavors.
What not to do when removing odor
Some “tips” from the Internet can ruin refrigerator or harm your health. Avoid these mistakes:
- ❌ Use bleach or bleach. They destroy plastic, leave toxic fumes and can corrode metal parts.
- ❌ Put scented candles or air fresheners in the refrigerator. They don't work at low temperatures, and wax or alcohol can get on food.
- ❌ Vacuum the internal surfaces. This will damage the antibacterial coating and can suck in small parts (for example, shelf fastenings).
- ❌ Heat the refrigerator to “accelerate weathering.” Overheating deforms the seals and increases emissions VOCs.
- ❌ Use essential oils (lavender, tea tree). They leave greasy stains on the plastic and can change the taste of products.
You need to be especially careful with refrigerators, where which:
- 🔋 Inverter compressor (for example, Samsung Digital Inverter or LG Linear) - harsh chemicals can damage electronic sensors.
- ❄️ System
Total No Frost- aggressive substances disrupt the operation of fans. - 🛡️ Antibacterial coating (for example, BioFresh in models Liebherr) - vinegar or alcohol removes the protective layer.
How to speed up weathering: non-obvious life hacks
If the smell is persistent and there is no time to wait, use these techniques:
- Fan + soda. Install a small fan (for example, Xiaomi Smartmi) opposite the open refrigerator and sprinkle soda on the shelves. The air flow will enhance the absorption of odors.
- Salt + rice Mix rice and salt in equal proportions, scatter on plates. Rice absorbs moisture, and salt absorbs chemical compounds.
- Freezer. If the smell is stronger in the freezer, put a bag of silica gel (those balls from shoe boxes) there for 12 hours.
- UV lamp. A bactericidal lamp (for example, Philips TUV 11W) will kill germs that increase the odor in 30 minutes. Use only in an empty refrigerator!
For models with zones. freshness (for example, Samsung Twin Cooling Plus or Bosch VitaFresh) there is a separate life hack: put them in these compartments for 24 hours. applesThey emit ethylene, which neutralizes chemical vapors.
Prevention: how to prevent the smell from returning
Even after successful removal the smell may return if you do not follow the operating rules. Follow these recommendations:
- 📅 Regular cleaning. Wash the refrigerator every 2-3 months with a solution of soda (1 tablespoon per 1 liter of water). data-i="221">Pack food in airtight containers (for example
No Frostuse special sprays (for example, Topperr 3036). - 🍎 Proper storage of food. Pack food in airtight containers (eg. Tupperware or Lock&LockAvoid open cans and bags.
- 🧊 Humidity control. Excess moisture increases odors. (for example, Silica Gel) or regularly wipe off condensation.
- 🔄 Ventilation. Once a month, leave the refrigerator open for 1-2 hours (after unplugging it).
If you often defrost the refrigerator, after the procedure, wipe the walls citric acid solution (1 tsp per 1 liter of water). This will remove remaining ice and prevent the formation of mold.
⚠️ Attention: In refrigerators with automatic defrosting (Frost Free, Full No Frost) you cannot use mechanical methods for cleaning ice (knives, scrapers). This will damage the defrosting system.
FAQ: answers to frequently asked questions
How long? Does the smell usually last in a new refrigerator?
With proper preparation (ventilation, cleaning, absorbers), the smell goes away 3–7 days. Without treatment, it can persist up to 1-3 months, especially in budget models with a thick layer of polyurethane foam.
Is it possible to use a refrigerator with a smell to store food?
Short-term (1-2 days) - yes, but products need to be sealed. Long-term storage is not recommended: VOCs penetrate the film and spoil the taste of food. odors butter, cheeses, sausages and bread.
Does the ozonator help better than activated carbon?
The ozonator is more effective against bacteria and mold, but does not always cope with chemical odors (for example, styrene from plastic). Coal absorbs VOCs. For the best result, combine both methods: first an ozonator, then coal to consolidate the effect.
Why is the smell stronger in the freezer?
The temperature in the freezer is lower, so volatile compounds condense on the walls and evaporate more slowly. In addition, the freezer seal is often made of more porous rubber, which “gives off” the factory smell longer.
Is it possible to return the refrigerator to the store because of the smell?
According to the Law “On Protection”. consumer rights" (Article 18), you can return the equipment within 14 daysif the smell is manufacturing defect (for example, due to a defective seal or excessive amount of glue). However, the usual “smell of newness” is not considered a defect. To prove a defect, you will need examination (it is paid by the seller if the claim is made). justified).
