An unpleasant aroma inside the refrigerator compartment can ruin the taste of even the highest quality products and turn the cooking process into a test. Often, owners are faced with a situation where, it would seem, the shelves are washed, but persistent odor does not disappear anywhere, exuding the aromas of spilled milk or a forgotten piece of meat. The problem cannot be ignored, since bacteria actively multiply in the warm environment of the compressor compartment and on the walls.
Before looking, how to clear the smell in the refrigeratorit is necessary to understand the nature of its occurrence. Sometimes it is enough to simply defrost the system No Frost or replace the carbon filter, but in other cases, deep disinfection of the entire internal surface is required. In this article, we will look at proven methods that will help restore freshness to your appliance.
The very first action you should take is to audit the contents. Throw away any expired food, check containers for seals, and clean up spills. Only after complete unloading and initial cleaning can you begin to use special neutralization products.
Causes of persistent odors
Understanding the source of the problem is half the success in the fight for freshness. Most often, the culprits are spoiled products that have been in the chamber for a long time without control. As bacteria multiply, they release gases that are absorbed into plastic walls and rubber seals, creating an unpleasant odor.
The second common cause is a clogged drainage hole. The water, which should flow into a special tray above the compressor, stagnates inside the tube. There the process of rotting begins, and the air from the drainage enters back into the chamber, carrying with it a musty aroma.
- 🦠 Mold proliferation in hard-to-reach corners of the chamber.
- 🥛 Spilled liquids (milk, juice, broth) that have fallen under removable shelves.
- 🔌 Malfunction of the ventilation system or carbon filter.
⚠️ Attention: If the smell appears suddenly and resembles the smell of burning or chemicals, immediately unplug the device. This may indicate overheating of the wiring or a refrigerant leak, which requires the intervention of a technician.
It is also worth considering that new devices may have a specific technical smell of plastic. In this case, aggressive chemicals are not needed, just wipe the surfaces with a soda solution and let the refrigerator “ventilate” while turned off.
Preparation for cleaning and defrosting
Effective cleaning is impossible without proper preparation. You need to completely empty the refrigerator of food and remove all removable elements: shelves, drawers, egg trays and bottle holders. It is better to wash these parts separately in warm water using dish soap.
If you have a model with a drip defrosting system, leave the doors open for at least 2-3 hours. The ice should completely melt and the water should drain. To speed up the process, you can use a hairdryer, but you need to be careful when directing hot air onto the plastic so as not to deform it.
☑️ Preparation checklist
After defrosting, carefully inspect the rubber seal around the perimeter of the door. It is in its folds that dirt and mold most often accumulate, which are the source musty smell. Wipe the seal with a cotton swab dipped in hydrogen peroxide or vinegar.
It is important not to forget about the drainage hole. It can be cleaned using a special brush or soft wire wrapped in cloth. Carefully pour some warm water into it to check the patency of the canal.
Folk remedies for eliminating odor
There are many ways how to clear the smell in the refrigeratorusing available means. They are safe, cheap and often more effective than aggressive chemicals. One of the most popular methods is the use of baking soda.
Soda is an excellent absorbent. Dissolve 2 tablespoons of powder in a liter of warm water and wipe all internal surfaces with this solution. To enhance the effect, you can leave an open container with dry soda on the shelf for a day.
- 🍋 Citric acid or lemon juice: perfectly breaks down fat and interrupts extraneous aromas.
- ☕ Ground coffee: absorbs odors, can be used both in dry form and in the form of a solution.
- 🍞 Black bread: a slice of fresh bread left in the chamber overnight absorbs unpleasant odors.
⚠️ Attention: Do not use chlorine-containing products (for example, “Beliznaya”) to wash internal plastic surfaces. Chlorine can react with plastic and increase the smell, as well as ruin the color of the shelves.
Acetic acid has also proven to be a powerful disinfectant. Mix table vinegar with water in a 1:1 ratio. This solution will not only remove the odor, but also destroy bacteria. However, after processing, be sure to ventilate the chamber to get rid of the sharp vinegar aroma.
Use of professional absorbers
If traditional methods do not seem effective enough to you or you are looking for a long-term solution, pay attention to industrial odor absorbers. They are sold in hardware stores and supermarkets in the form of gels, balls or tablets.
Such devices operate on the principle of active adsorption. Inside the housing is a substance (often activated carbon or zeolite) that draws in air and traps odor molecules. The validity period of one block is usually from 1 to 3 months.
| Type of absorber | Principle of operation | Service life | Features |
|---|---|---|---|
| Gel | Evaporation of active substances | 2-3 months | Has its own aroma |
| Coal | Adsorption by coal pores | 3-4 months | Odorless, hypoallergenic |
| Electric | Air ionization | 5-7 years (battery) | Requires battery replacement |
| Mineral | Moisture and odor absorption | Up to 1 year | Can be regenerated in the sun |
Electric absorbers powered by batteries are considered the most effective. They not only mask the odor, but destroy bacteria and ethylene, which accelerates the spoilage of vegetables and fruits. This allows products to be stored longer.
Can ozonizers be used?
Yes, household ozonizers effectively kill bacteria and eliminate odors. However, they need to be turned on in an empty refrigerator for 10-15 minutes, since ozone in high concentrations is harmful to humans and can oxidize some types of plastic with prolonged exposure.
Specialized household chemicals
When “heavy artillery” is required, special sprays and foams for cleaning refrigerators come to the rescue. They are designed taking into account the safety of contact with food and the materials from which the cameras are made.
When choosing a product, pay attention to the “food safe” or “environmentally friendly” labeling. Such sprays often contain enzymes that break down organic contaminants at the molecular level, eliminating the very cause of the odor rather than masking it.
You must use chemicals strictly according to the instructions. Typically, the product is applied to the surface, left for a few minutes to react, and then thoroughly washed off with water. Do not allow aggressive components to enter the ventilation system.
Pay special attention to washing the external surfaces and door handles, since they are the ones that come into contact with your hands, where food particles or dirt may remain. Regular treatment with an antiseptic will help maintain hygiene.
Prevention of odors
So the question "how to clear the smell in the refrigerator" did not occur too often, it is important to follow the rules for storing food. All liquids should be covered, and strong-smelling foods (fish, smoked meats, cheese) are best stored in airtight containers.
Regularly audit your supplies. Make it a habit to check the contents of your refrigerator once a week and throw away any food that is starting to spoil. Cleanliness inside the chamber directly depends on your discipline.
- 🧼 Wipe the shelves with a damp cloth immediately after getting dirty.
- 🌡️ Monitor the temperature so that food does not spoil faster.
- 📦 Use food containers instead of plastic ones packages.
⚠️ Attention: Refrigerator manufacturers may change recommendations for the care of specific models of coatings (for example, antibacterial coating Hygiene Fresh+ or Antibacterial Silver). Always check the official instructions for your device before using new cleaning products.
It is also recommended to keep a permanent odor absorber (an open pack of soda, an activated carbon tablet or a special ball) in the refrigerator. This will create background protection against the appearance of unpleasant aromas.
Do not forget about ventilation. If the refrigerator is built into a kitchen unit, make sure there is enough clearance around it for air circulation. Overheating of the back wall can contribute to the appearance of the smell of burnt dust or plastic.
FAQ: Frequently asked questions
How to quickly remove the smell of fish from the refrigerator?
A solution of vinegar or lemon juice will help best. Wipe all surfaces, including seals. You can also use an activated carbon tablet, crushed into powder and scattered on the shelves for several hours.
Why did the smell appear after defrosting?
Perhaps water has accumulated in the drainage system or under the evaporator, in which bacteria have multiplied. When defrosting they became active. The drainage hole must be thoroughly washed and the chamber treated with an antibacterial agent.
Is it possible to wash the refrigerator with soap?
It is not recommended to use ordinary toilet or laundry soap, as it leaves a film and its own smell. It is better to use special products or a solution of baking soda, which are easily washed off and are not absorbed into the plastic.
How often should you wash the refrigerator?
General cleaning with defrosting is recommended every 3-4 months. Wet cleaning of shelves and drawers should be done every 2 weeks or immediately after contamination.
