The sudden appearance of a musty, earthy aroma in the kitchen often becomes an unpleasant surprise for any home cook. This is a sure sign that a fungus has settled inside the chamber, which requires immediate intervention. Ignoring the problem not only spoils the taste of stored products, but also creates a dangerous environment for the health of all household members.
Mold can penetrate hard-to-reach places, including seals and ventilation systems. To eliminate the smell, it is not enough to simply wipe the shelves with a damp cloth. It is necessary to carry out a comprehensive procedure, including defrosting, mechanical cleaning and chemical treatment of surfaces.
In this article we will analyze in detail how to clean a refrigerator from the smell of mold available means. You will learn about proven disinfection methods and preventive measures that will help avoid the reappearance of fungus in the future.
Causes of mold in the refrigerator
The main reason for the spread of fungal spores is high humidity combined with the heat that occurs when rare use of the device or system malfunction No Frost. When moisture stagnates in drainage holes or under containers, ideal conditions are created for the proliferation of microorganisms.
Often the source of the problem is spoiled food left on shelves for too long. Even microscopic particles from rotting vegetables or spilled milk can start the fermentation process. Mold spores are incredibly volatile and quickly spread throughout the entire volume of the chamber.
There is another hidden reason - pollution drainage system. If the condensation drain hole is clogged with crumbs or slime, water will begin to accumulate at the bottom, causing the plastic to turn black. It is this stagnant body of water that often becomes the epicenter of an unpleasant odor.
Breaking the tightness of the door also allows the penetration of warm air, which leads to the formation of abundant condensation. A rubber seal that does not fit tightly, is constantly wet and dirty, becomes a breeding ground for black mold.
Preparation for general cleaning and defrosting
Before you begin an active fight against fungus, it is necessary to completely empty the internal space. Remove all shelves, vegetable drawers and removable parts. It is better to wash them separately in the bathtub or under the shower using hot water.
Be sure to unplug the device from the power supply. This is a critical safety step, as working with water and electrical appliances are incompatible. Leave the doors open for at least 2-3 hours to completely defrost the evaporator.
During this time, the ice build-up will have time to melt and the water will drain. Do not try to chip the ice with a knife or sharp objects, as you can damage evaporator pipelinewhich will lead to freon leakage and expensive repairs.
While the defrosting process is in progress, inspect the products. Ruthlessly throw away anything that shows signs of spoilage, bulging packaging or a questionable odor. Even if the product looks normal, but lies next to a source of mold, it is better not to risk eating it.
⚠️ Attention: Never use a hairdryer or other heating devices to defrost. A sharp temperature change can lead to cracks in the plastic case or damage to the internal coating of the chamber.
Choice of effective cleaning products
The household chemicals market offers many specialized sprays, but folk remedies often turn out to be no less effective and safer. The main requirement for a cleaning agent is the ability to destroy fungal spores, and not just mask the odor.
One of the most accessible and powerful agents is baking soda. It perfectly absorbs odors and has a mild abrasive effect. To prepare the solution, dilute 2 tablespoons of soda in a liter of warm water.
Acetic acid has also proven to be excellent. antiseptic. Table vinegar 9%, diluted with water in a 1:1 ratio, can dissolve fatty deposits and kill bacteria. However, you should be aware of its pungent odor during processing.
Hydrogen peroxide is another powerful oxidizing agent that effectively fights mold. It is safe for food surfaces and leaves no toxic residue. You can use a ready-made pharmaceutical solution or a spray based on it.
If you prefer professional chemicals, choose products labeled “antibacterial” or “anti-mold”. Avoid aggressive chlorine-containing solutions on rubber parts, as chlorine can destroy the structure of the seal.
Is it possible to use bleach?
It is not recommended to use pure chlorine (White) on the inner walls of the refrigerator. Chlorine fumes can be absorbed into plastic and then transferred to food. If the situation is critical, use a highly diluted solution (1 capful per 5 liters of water) and only for initial treatment, then rinse thoroughly with water.
Step-by-step instructions: how to clean a refrigerator
The washing process should be systematic. Start by treating the top shelves and gradually work your way down. This will prevent re-contamination of already clean surfaces by flowing dirty water.
Carefully wipe all internal walls, paying special attention to the corners and joints of the panels. It is in these places that plaque most often accumulates. Use a soft sponge or microfiber to avoid scratching the glossy plastic.
Pay special attention rubber seal to the door. Gently bend it around the perimeter and wipe the inner fold with a cotton swab dipped in a disinfectant solution. Black dots of mold are often hidden there.
After the main wash, be sure to rinse all surfaces with clean water to remove any remaining cleaning agent. Then wipe the chamber dry with paper towels or dry rags.

Cleaning the drainage system and hard-to-reach areas places
If the smell persists after general cleaning, the problem lies in the drainage hole. It is usually located on the back wall of the camera, at the bottom. Condensate goes through it into a special container above the compressor.
To clean, use a special brush, soft wire or a long cotton swab. Carefully insert the tool into the hole and make several rotational movements to break through the plug of mucus and dirt.
After mechanical cleaning, pour a small amount of disinfectant solution (for example, soda or peroxide) inside. This will help disinfect the canal from the inside. After 10-15 minutes, you can pour clean water into it to wash away the residue.
Don't forget to check the water collection tray, which is located at the back of the refrigerator, above the compressor. You can get to it by moving the unit away from the wall. Remove the tray, wash it with a brush and return it to its place.
⚠️ Attention: When cleaning the drainage, do not use hard metal objects. By piercing the plastic tube inside the case, you can break the tightness of the system, which will require calling a technician.
Comparison table of cleaning products
To make it easier for you to choose the optimal cleaning product, we have prepared a comparison table. It will help evaluate the effectiveness and safety of various options.
| Medicine | Effectiveness against mold | Safety for products | Odor removal |
|---|---|---|---|
| Food soda | Medium | High | High |
| Table vinegar | High | High | Medium (masks) |
| Hydrogen peroxide | Very high | High | Low |
| Special. sprays | High | Requires washing | High |
As can be seen from the table, hydrogen peroxide is the leader in destroying spores, but soda is better at absorbing odors. Combining these remedies gives the best result.
The use of specialized chemistry is justified in advanced cases when traditional methods have not helped. However, after them, a more thorough rinsing is required.
Prevention of the reappearance of fungus
To ensure that the problem how to clean the refrigerator from the smell of molddoes not arise again, it is important to follow simple operating rules. Regularly check the expiration dates of products and immediately remove spoiled items.
Do not put hot foods in the chamber. This creates an excess amount of steam, which settles on the walls and promotes the growth of bacteria. Allow the food to cool to room temperature before storing.
Once a month, carry out a preventive wipe of the shelves and seals with a weak solution of vinegar or soda. It only takes 5 minutes but will keep the inside of the chamber fresh. Also keep the outside clean by wiping the body from dust.
Check the door for tight fit. If the rubber is worn out or the door is warped, moisture will constantly condense. In this case, it may be necessary to adjust the hinges or replace the seal.
Following these recommendations will allow you to maintain an ideal microclimate inside your refrigerator. Cleanliness and order guarantee the safety of food and a pleasant aroma in your kitchen.
What is the best way to wash a rubber seal so that it does not turn black?
For rubber parts, a solution of laundry soap or a weak solution of vinegar is best. Chlorine-containing products (such as White) should not be used, as they dry out the rubber, making it brittle, and can change the color of the seal. After washing, be sure to wipe the folds dry.
What to do if the smell of mold remains after washing?
If the smell persists, it means that fungal spores have penetrated deep into the plastic or into the ventilation system (for No Frost models). Try treating the inner walls with a solution of hydrogen peroxide and leaving the refrigerator open for a day. In extreme cases, it may be necessary to replace the thermal insulation material, but this is a job for a master.
How often should you wash the refrigerator?
It is recommended to carry out general cleaning with defrosting once every 3-4 months. Preventive wiping of shelves and checking products should be done weekly. If you notice spilled liquid or crumbs, clean them up immediately, without waiting for scheduled cleaning.
Can I use a steam cleaner for a refrigerator?
Using a steam cleaner for interior plastic is not recommended. The high temperature of the steam can deform the thin plastic of the shelves and damage the factory coating of the chambers. A steam cleaner is good for external metal surfaces, but inside it is better to use it manually using soft agents.
