How to use soda to get rid of the smell in the refrigerator

The appearance of foreign aroma in in the refrigerator compartment is not just discomfort when opening the door, but also a signal that the hygiene of food storage has been violated. Most often, the source of the problem is spoiled vegetables, spilled liquids or semi-finished products that have been lying around for a long time, which have been absorbed into plastic walls and rubber seals. Ignoring this problem can lead to the fact that even fresh food will begin to acquire an unpleasant taste.

The most effective, safe and affordable remedy for combating this scourge is ordinary baking soda (sodium bicarbonate). Unlike aggressive chemistry, it does not leave toxic traces, is completely washed off with water and has powerful absorbent properties. Baking soda is able to neutralize acidic and alkaline compounds that cause stench, turning them into harmless salts.

Before proceeding to the active phase cleaning, it is necessary to understand the nature of the odor in order to prevent its recurrence in the future. It is important to act consistently, without skipping the preparation steps, since simply sprinkling powder on the shelves will not be enough to deeply clean the ventilation system and hard-to-reach corners.

Causes of persistent odors

A refrigerator is a closed air circulation system where odors spread instantly. The main source of problems is often the human factor: a forgotten piece of cheese, a burst milk carton, or a rotting parsley root that has rolled into a far corner. However, there are also technical reasons, for example, clogging of the drainage hole, where mucus and bacteria accumulate, creating a persistent stench.

The plastic surfaces of the inner walls and drawers have a porous structure that actively absorbs volatile substances. If the smell of fish, onions or garlic gets into the chamber, it can persist for weeks. Rubber seal The door is also an ideal environment for the growth of mold, which gives a specific musty aroma, especially if the door was not tightly closed.

Sometimes the cause is a malfunction of the No Frost system or drip defrosting. If the water does not go into the evaporator pan, but stagnates inside the housing, the process of rotting begins. In such cases, simple washing will not help - defrosting and cleaning the drainage will be required. But even in this case, soda will be the first step to eliminating the consequences.

It should be borne in mind that new refrigerators may smell like plastic or factory grease. This is normal for the first weeks of operation, but if the aroma does not disappear, it can also be neutralized with the help of adsorbents. Activated carbon or soda does an excellent job of the “first start-up” of the equipment.

Preparing the refrigerator for cleaning

The effectiveness of any cleaning directly depends on the quality of the preliminary preparation. You can’t just sprinkle baking soda on top of food or dirt - this will only spread the problem over the surface. The first and most important step is to completely empty the refrigerator compartment of its contents.

You need to remove all shelves, drawers, egg containers and bottle holders. It is better to wash glass and plastic elements separately in the bathtub or sink using detergent. This will allow you to gain access to the guides and the back wall, where bacteria most often accumulate.

If you are using a refrigerator with a system No Frost, it is not necessary to completely defrost it if there is no ice crust on the walls. However, turning off the power during cleaning (15-20 minutes) will protect you and your equipment from accidental short circuits when moisture comes into contact with electrical components.

⚠️ Attention: Never use hot water to wash glass shelves if they have just been removed from the freezer - a sudden temperature change may cause the glass to crack.

Preparing a cleaning solution from soda

Soda is universal, but different types of dirt and tasks require different concentrations of solutions. For routine prevention and removal of light odors, dry powder is sufficient, but for general cleaning you will need liquid formulations. The correct proportion of components guarantees safety for plastic and effectiveness against microbes.

The base solution is prepared at the rate of one tablespoon of sodium bicarbonate per liter of warm water. Warm water speeds up the dissolution reaction, making the mixture smooth. This composition is ideal for wiping interior walls, doors and rubber seals. It does not leave streaks and is easily washed off.

To combat greasy stains or dried-on dirt, you can make a paste. Mix soda with a small amount of water in a 2:1 ratio until it becomes thick sour cream. This mass is applied locally to problem areas, left for 10-15 minutes, and then removed with a damp cloth. The abrasive properties of soda in this form gently polish the surface without scratching it.

Is it possible to mix soda with vinegar?

Mixing soda and vinegar causes a violent chemical reaction with the release of carbon dioxide. This is effective for cleaning pipes, but for cleaning a refrigerator it is less effective than using the components separately, since the reaction neutralizes the cleaning properties of both substances.

It is important to use only fresh soda that has not caked into a hard lump. If the powder has been lying in the kitchen for a long time and has absorbed foreign odors, its cleaning properties may be reduced. For an ideal result, it is better to open a new pack.

Step-by-step instructions for eliminating odor

The cleaning process requires a systematic approach. First we remove visible contaminants, then we work with microflora and odors. Move from top to bottom so that dirty water does not drip onto the already washed lower shelves.

Start by wiping all surfaces with the prepared soda solution. Use a soft sponge or microfiber, avoiding hard brushes, which can leave micro-scratches on the plastic. Bacteria will subsequently accumulate in the scratches, and the smell will return.

• 🧼 Thoroughly wipe the ceiling of the refrigerator compartment and the upper shelves, where fumes often settle.
• 🚿 Pay special attention to the back wall and the area around the ventilation holes - air circulates there.
• 🔍 Check the rubber seal around the perimeter of the door: push the folds apart and wash them with a cotton swab dipped in soda solution.
• 🥤 Do not forget to rinse the door handles and the outer surface of the case, if it also has an unpleasant odor.

After wet cleaning, be sure to Wipe all surfaces dry with a clean cloth. The remaining moisture is a haven for mold. Let the refrigerator stand open for 15-20 minutes so that the remaining moisture completely evaporates, and the smell of soda (if any remains) disappears.

Soda as a permanent odor absorber

After general cleaning, it is important to consolidate the result and prevent the appearance of new aromas. Here soda acts as an adsorbent. Unlike flavorings, which mask the smell, soda absorbs molecules of odorous substances from the air.

The easiest way is to pour half a glass of dry soda into a small open container (glass, yogurt jar) and place it on one of the shelves. It is recommended to change such an absorber once a month, as its effectiveness decreases over time. To prevent the powder from scattering accidentally, the container can be covered with gauze or cloth.

There are also more aesthetic options for use. You can make a soda sachet by wrapping the powder in a coffee filter or handkerchief, or by making holes in the lid of a plastic jar. Some housewives add a few drops of lemon or mint essential oil to the soda to create a light, fresh aroma, but this is a matter of personal preference.

If the smell is very persistent, you can sprinkle a thin layer of dry soda on the bottom of the refrigerator (on a towel or in a tray) and leave it overnight with the appliance turned off. In the morning, carefully vacuum or sweep away the powder.

What not to do: common mistakes

The desire to quickly get rid of a problem sometimes leads to damage to equipment. There are a number of actions that are strictly not recommended when cleaning the refrigerator with soda or other means. Violation of these rules can lead to damage to plastic parts or corrosion of metal elements.

Never use pure soda in the form of an abrasive powder on glossy plastic surfaces without adding water. Microparticles of soda can leave dull scratches, which subsequently begin to collect dirt even more actively. Always either dissolve the powder or use a soft, damp sponge.

⚠️ Warning: Do not attempt to clean the internal electrical contacts, defrost heaters or fan motor with soda solution. Water and alkali can cause short circuits or corrosion of contacts.

Also, do not mix soda with chlorine-containing products (for example, "White"). Although there will not be a violent reaction like with acid, the effectiveness of such a mixture is questionable, and the risk of damage to rubber seals increases. The rubber may become brittle and crack.

Another mistake is using hot water to defrost or speed up cleaning. The plastic of modern refrigerators can be deformed from high temperatures, which will lead to a violation of the geometry of the shelves or the appearance of cracks.

Preventing the appearance of unpleasant odors

The best way to deal with odors is to prevent them. Following simple food storage rules will allow you to forget about the problem of stench. Regular inspection of the contents of the refrigerator should become a habit.

Use airtight containers to store foods with a strong odor (fish, smoked meats, onions). This will not only preserve the freshness of other products, but also protect the inner walls of the chamber from absorbing aromas. Glass dishes Those with tight lids are best suited for this.

Once a week, conduct a quick inspection of the shelves and throw away products with an expiration date. Wipe the shelves with a damp cloth, even if there is no visible dirt. It takes 2 minutes, but keeps the chamber fresh.

How often should you completely wash the refrigerator?

General cleaning with complete defrosting and washing of all parts is recommended once every 3-4 months. If you have a refrigerator with a No Frost system, once every six months is enough, subject to regular weekly preventive maintenance.

Will soda help if the smell comes from the freezer?

Yes, the principle of operation is the same. However, the freezer must be defrosted before cleaning. After defrosting, wipe the walls with a soda solution, dry and turn on. For prevention, leave an open jar of soda inside.

What to do if the smell does not go away after cleaning?

If all surfaces are washed, but the smell remains, it may have penetrated into the thermal insulation layer through microcracks or clogged in the drainage hole. Try cleaning the drain with a special brush or soft wire. In difficult cases, you may need to call a technician to disassemble the internal panel.

Can you use soda to clean external stainless steel?

Yes, but with caution. The solution must be completely homogeneous, without crystals. Wipe strictly along the grain of the metal. After treatment, be sure to polish the surface with a dry soft cloth to avoid the appearance of white stains.
