How to get rid of the smell of mold in the refrigerator at home

Unpleasant a musty aroma in the kitchen often becomes a surprise, which is discovered at the most inopportune moment. The smell of mold in the refrigerator not just disgusting, it signals the proliferation of dangerous microorganisms, the spores of which can penetrate into food. This problem cannot be ignored, since the fungus can settle on rubber seals and inside the ventilation ducts, making the air inside the chamber toxic.

Many housewives try to mask the problem with air fresheners or simply put an open pack of soda, but this is only a temporary solution. In order to permanently eliminate the smell of dampnessit is necessary to find the source of infection and carry out a comprehensive sanitation of all surfaces. In this article, we will analyze an algorithm of actions that will help restore freshness to your unit even in the most advanced cases.

The cleaning process requires patience and consistency, but the result is worth it. Properly carried out disinfection will extend the life of equipment and protect the health of your family from allergens. Let's figure out which products really work and how not to damage plastic parts when cleaning.

Finding the source of the unpleasant odor

Before grabbing a rag and detergent, you need to conduct a thorough inspection of the contents and structural elements. Often source of odor hides not in plain sight, but in hard-to-reach places where we rarely look during normal cleaning. Carefully inspect every corner, including the bottom of the vegetable drawers and the space behind the back wall.

Particular attention should be paid to products with a long shelf life that may have been “forgotten” in the depths of the freezer or on the top shelves. Even one moldy piece of cheese or a jar of pickles, the lid of which is not tightly closed, can spoil the atmosphere in the entire volume. Fungal spores they are quickly carried by air currents of the No Frost system, settling on clean surfaces.

If the food supply is clean, the problem may hide in technical units. Moisture that accumulates in the drainage system is an ideal environment for the development of bacteria. It is also worth checking the rubber seal the doors: it is in their folds that black mold most often settles, which is difficult to notice during a quick inspection.

Stages of complete defrosting and washing

The most effective way to defeat fungus is to completely defrost the unit. Unplug the appliance, remove all food and shelves, leaving the doors open for at least 24 hours. During this time ice crust it will melt, and along with it part of the pathogenic microflora, which cannot survive without cold and moisture, will go away.

While the equipment is thawing, take care of the removable elements. It is better to wash shelves, drawers and containers in the bath or shower using hot water. For plastic parts, laundry soap or a solution of baking soda is ideal, which do not leave a chemical odor and are safe for contact with food.

The inner walls of the chamber should be wiped dry after defrosting. Do not use abrasive sponges, as micro-scratches on plastic will become a new home for bacteria. Hygienic treatment should be gentle but thorough, covering every centimeter of the surface.

Folk remedies for removing fungus

Home recipes are often more effective than aggressive chemicals, especially when it comes to food chambers. Table vinegar is rightfully considered the leader: a solution in a 1:1 ratio with water perfectly breaks down fatty deposits and kills mold spores. After treatment with vinegar, it is necessary to ventilate the chamber well so that the specific aroma of the acid disappears.

Hydrogen peroxide is another powerful weapon against biological contaminants. It not only disinfects, but also whitens surfaces, removing dark stains from fungus. It is enough to apply a 3% solution on a napkin and wipe the problem areas, paying special attention to joints and corners. Citric acid or fresh lemon juice will help not only disinfect, but also give the interior a pleasant citrus aroma. However, you should be careful with the concentration so as not to damage the plastic. joints and corners.

Citric acid or fresh lemon juice will help not only disinfect, but also give the interior a pleasant citrus aroma. However, you should be careful with the concentration so as not to damage the plastic. Natural antiseptics safe for children and animals, which makes them the preferred choice for many families.

Professional chemistry and antiseptics

If traditional methods do not seem powerful enough, you can turn to specialized means. There are many sprays and gels on the market designed specifically for kitchen appliances. When choosing, it is important to pay attention to the label “for food surfaces” and the absence of chlorine in the composition, since its vapors can be dangerous.

Silver-based antiseptics create a thin protective film on the surface that prevents the re-growth of bacteria for a long time. Such products are often used in premium models with the function antibacterial coating, but can also be applied manually.

Ozone air purifiers are a modern gadget that can be placed inside during downtime. Ozone actively oxidizes organic pollutants and completely destroys odors, penetrating even into the pores of plastic. This is an expensive but extremely effective method for complex cases.

⚠️ Attention: When using chemical sprays, be sure to wear gloves and a respirator. After treatment, thoroughly rinse all surfaces with clean water several times to prevent chemicals from getting on the products.

Cleaning the drainage system and seals

One ​​of the most common reasons for the return of odor is a clogged drainage hole. It is located on the back wall of the refrigerator compartment and drains condensate into a special container above the compressor. If water stagnates there, the process of rotting begins, and the smell returns a few days after cleaning.

To clean the channel, you can use a special brush, which is often included, or an ordinary wire with cotton wool wound. Carefully push the tool inside, trying not to damage the tube, and pour in a warm soda solution or a special pipe cleaner (in small quantities).

The rubber door seal requires a special approach. It needs to be folded back and the folds wiped with a cotton swab dipped in vinegar or peroxide. If a black coating has already formed on the rubber and cannot be wiped off, it may be necessary replacing the sealas the fungus could penetrate deep into the structure of the material.

What to do if the drainage is clogged with ice?

If the drainage hole is frozen, do not try to pierce it with a knife or sharp objects. Turn on the quick defrost mode or simply leave the refrigerator turned off with the doors open for a longer period. The ice will melt on its own, and the water will leave by gravity.

Comparison of cleaning methods and their effectiveness

The choice of method depends on the degree of contamination and the type of your refrigerator. For regular care, simple remedies are sufficient, while long-standing problems require radical measures. Below is a table to help you choose the best option for your situation.

You should not rely on just one method. A combination of mechanical cleaning, chemical treatment and subsequent drying gives the best results. Remember that prevention it is always cheaper and easier than dealing with the consequences.

Regularly check the expiration dates of products and immediately dispose of spoiled ones. Even if it seems that the product is “nothing yet,” it is better not to risk it. Mold begins to release mycotoxins long before a visible fluffy coating appears.

⚠️ Attention: If after complete defrosting and processing the smell returns within 2-3 days, the problem may be technical (for example, burnt wiring or freon leakage from characteristic odor). In this case, you need to call a specialist for diagnostics.

Prevention of mold

To ensure that the question “how to get rid of the smell of mold in the refrigerator” no longer bothers you, it is important to follow simple operating rules. First and foremost, store all foods in closed containers. This will prevent the spread of odors and spores even if one of the ingredients is damaged.

Regularly, at least once a month, wipe the shelves with a damp cloth, without waiting for visible dirt. It is also useful to keep odor absorbers inside: activated carbon, special balls or even an activated carbon tablet in a small container. They work as adsorbentsabsorbing excess moisture and aromas.

Watch the temperature. Too high a temperature promotes bacterial growth, while too low a temperature can cause the drain to freeze. The optimal settings are in the range from +2 to +4 degrees for the main chamber. Modern models often have indicators that indicate violation of the regime.

Can I use bleach (White) to clean the refrigerator?

Chlorine-containing products can only be used in extreme cases and in strong dilution, since chlorine aggressively affects plastic and rubber seals, making them brittle. In addition, chlorine vapor can be absorbed into plastic and take a long time to dissipate, giving products a chemical taste. It is better to replace bleach with oxygen bleaches or vinegar.

Why does the smell return immediately after cleaning?

Most often this means that the source of the smell (mold in the drainage, under the sheathing or in the seal) has not been eliminated, but only masked. It is also possible that a new portion of spoiled food got into the chamber, or that the refrigerator was not completely dried before turning on, which created ideal conditions for the rapid growth of bacteria.

How often should you defrost the refrigerator?

Even models with the No Frost system are recommended to be defrosted and washed completely at least once a year. This is necessary to prevent the formation of ice plugs in the drainage and remove dust from the heat exchanger, which can also become a source of an unpleasant odor when the compressor heats up.
