How to get rid of the smell in the refrigerator and freezer at home

An unpleasant odor in the refrigerator is a common problem faced by owners of household appliances, regardless of the brand or model. The appearance of foreign odors can be caused by many factors: from accidentally spilled milk and spoiled food to bacterial growth in hard-to-reach places or clogged drainage systems. Ignoring this problem is unacceptable, since odors can be absorbed into the plastic of internal shelves and rubber seals, being transferred to fresh products and changing their taste.

Before starting an active fight against odors, it is necessary to conduct a thorough audit of the contents of the chambers. Often the source of the problem is a forgotten piece of cheese in the corner of a shelf or a leaking bag of meat that could have flowed into the cracks. In some cases, especially after defrosting, the smell may indicate more serious technical malfunctions, such as failure of the No Frost system or problems with air circulation.

In this article we will analyze in detail the algorithm for eliminating any odors, consider effective folk methods and professional remedies. You will learn how to properly prepare equipment for cleaning, which absorbents work best and how to prevent the problem from reoccurring in the future.

Finding and eliminating the source of the unpleasant odor

The first and most important step is to completely defrosting refrigeration equipment. Even if your model is equipped with a No Frost system, which supposedly does not require defrosting, for high-quality cleaning and elimination of ingrained odors, you need to unplug the device for at least 10-12 hours. At this time, all food should be removed and the doors should be left open for ventilation.

Carefully inspect all shelves, drawers and containers. Often the smell comes not from the walls of the chamber, but from plastic containers that have absorbed the aromas of fish, garlic or smoked meats. Glass and metal is easier to wash, while porous plastic requires special attention. If you find a spoiled product, it must be disposed of immediately, and the place where it was lying should be treated with a disinfectant.

• 🔍 Check the rubber door seal - food debris and mold often accumulate in the folds.
• 🧊 Inspect the drain hole on the back wall - a blockage here causes stagnation of water and a putrid odor.
• 🥫 Make sure that all products are tightly packaged and are not damaged.

⚠️ Attention: If after thorough cleaning and defrosting the smell of burning or chemicals persists, this may indicate a compressor malfunction or a refrigerant leak. In this case, further operation is dangerous.

Particular attention should be paid to the condensate drainage system. In models with drip system water flows into a special tray above the compressor. If the tube is clogged, water will stagnate inside, causing mold and a musty smell. You can clean the hole using a special brush or soft wire wrapped in rags.

Preparing the refrigerator for deep cleaning

After the source has been found and the equipment has been defrosted, the preparation stage for washing begins. It is important to use the correct tools to avoid damaging the interior surfaces. Plastic and painted metals are sensitive to abrasives and aggressive chemicals, so the choice of cleaning agent plays a key role in maintaining the appearance and functionality of the device.

Remove all removable elements: shelves, trays, vegetable drawers and bottle holders. It is best to wash them separately in a bathtub or large basin using warm water and a mild detergent. This will allow you to clean not only the visible surfaces, but also the joints, as well as the guides along which the shelves move. Thoroughly wipe the places where the shelves are attached inside the chamber.

To wash the inner walls, use a soft sponge or microfiber. Hard brushes can leave micro-scratches in which bacteria can subsequently accumulate. Movements should be smooth, without strong pressure, so as not to damage the cooling system hidden behind the plastic panels.

Effective folk remedies for eliminating odor

Folk methods are often more effective than household chemicals, since they are safe for food and do not leave chemical fragrances. One of the most popular remedies is baking soda. It has excellent absorbent properties and is able to neutralize acidic and alkaline odors.

To prepare the solution, dilute 2 tablespoons of soda in 1 liter of warm water. Wipe all interior surfaces with this solution. After drying, the soda does not require rinsing, but for a better effect, you can wipe it with a clean damp cloth. Activated carbon also works great, which needs to be crushed and scattered on saucers, leaving them in the chamber for a day.

• 🍋 Citric acid or lemon juice - perfectly removes fat and refreshes.
• ☕ Ground coffee is a powerful absorbent that eliminates the smell of fish and meat.
• 🍞 Brown bread - helps remove the smell of mold and dampness.

Another proven remedy is table vinegar. It disinfects surfaces and kills bacteria. The solution is prepared in a 1:1 ratio with water. However, it is worth remembering that vinegar has its own pungent odor, so after processing the chamber must be thoroughly ventilated. Do not use vinegar on rubber parts too often, as the acid can dry out the material.

Specialized chemicals and absorbents

If traditional methods do not help or the smell is too persistent, you can resort to using household chemicals. There are many sprays and gels on the market designed specifically for refrigerator care. They not only clean, but also create a protective film that prevents dirt from sticking.

When choosing a product, pay attention to its composition. It is important that it is biodegradable and does not contain chlorine, which can damage the plastic and leave toxic traces. Specialized foam cleaners are convenient because they do not drain and penetrate well into hard-to-reach places.

In addition to cleaning products, there are ready-made odor absorbers that are sold in hardware stores. They can be in the form of granules, gel beads or carbon filters. Such devices work continuously until you replace them, maintaining freshness inside the chamber.

How do carbon filters work?

Coal has a porous structure that physically traps molecules of odorous substances. One filter is enough for 2-4 months of active use, after which it must be replaced.

Features of cleaning the freezer

The freezer requires a special approach, since low temperatures preserve odors, but do not always completely destroy bacteria. If there is an odor in the freezer, for example from defrosted meat or fish, simply washing it out may not help. It is important to reach all corners here, including the space behind and under the containers.

In models with the system No Frost odor may be hidden in the evaporator or air ducts. It’s difficult to get there on your own, but you can try blowing out the system with a hairdryer (cold air only!) or using special sprays that evaporate at low temperatures. If the smell comes from old ice, the chamber must be completely defrosted to a “dry” state.

⚠️ Attention: Never use hot water to speed up the defrosting of the freezer. A sudden change in temperature can lead to cracks in the plastic box or damage to the evaporator tubes.

After washing the freezer, be sure to leave the door open for several hours to remove the smell of detergent and dampness. For prevention, you can put an open pack of soda or a bag of rice in the drawer, which will absorb moisture and extraneous odors during further use.

Prevention of odors and care

To ensure that the question “how to get rid of odors in the refrigerator” no longer arises, you must follow the rules for storing food. All products, especially those with a strong aroma (fish, spices, cheeses), should be stored in closed containers or cling film. This will not only preserve freshness, but also prevent mixing of odors.

Regularly audit your inventory. Make it a habit to check the expiration dates and condition of products at the back of the shelves once a week. Wipe the shelves with a damp cloth even during weekly cleaning, without waiting for visible dirt. Cleanliness is the best prevention of mold and bacteria.

• 🗓️ Once a month, wipe the seals with a soda solution.
• 🌬️ Make sure that the ventilation holes are not covered with food.
• 🧼 Remove any spills immediately liquids.

Also monitor the temperature. If the temperature in the chamber is higher than normal, food spoils faster. Check the thermostat settings and make sure the door closes tightly. A loose seal is a common cause of not only loss of cold, but also the entry of warm air, which promotes the proliferation of microorganisms.

Frequently asked questions (FAQ)

How to quickly remove the smell of fish from the refrigerator?

Lemon juice or a vinegar solution will help best. Wipe all surfaces with a solution (1 tablespoon of vinegar per liter of water), and then leave a saucer with ground coffee or activated carbon in the chamber for 12-24 hours. Be sure to check if fish have gotten into the drain hole.

Why is there a plastic smell in a new refrigerator and how to remove it?

The smell of new plastic is normal, it is caused by production processes. To remove it, wash the refrigerator with warm water and soap, dry thoroughly and leave the doors open for a day. An odor absorber can be used. If the smell is chemical and pungent, contact the service department, it may be defective.

Is it possible to use bleach to clean a refrigerator?

Using chlorine-containing products (for example, “Whiteness”) is highly not recommended. Chlorine is aggressive to plastic and rubber and can cause them to yellow and deteriorate. In addition, chlorine vapor can be absorbed into food. It is better to use specialized products or soda.

What to do if the smell appears after defrosting?

If the smell appears after defrosting, most likely, there is stagnant water with bacteria in the drainage system or pan. You need to find the drain hole, clean it with a brush and rinse it with a warm solution of soda or hydrogen peroxide. Also check the tray under the compressor (bottom back).
