An unpleasant aroma in the kitchen is often the result of a persistent smell of spoiled food in the refrigerator compartment. The source of the problem could be an accidentally spilled soup, a forgotten piece of fish, or simply unwashed shelves that have absorbed the aromas of various dishes. The use of chemical cleaning products with aggressive fragrances is not always effective, since they only mask the problem, and sometimes they themselves become a source of chemical odor.
Baking soda is a time-tested and safe product that helps not only remove visible dirt, but also neutralize odor molecules at a deep level. Unlike vinegar, which can irritate the mucous membranes, or chlorine-containing preparations, soda acts gently without damaging plastic parts and rubber seals. In this article, we will look at how to properly prepare equipment for cleaning, what proportions of the solution to use, and what to do if the smell has ingrained itself too deeply.
Before starting active actions, it is important to understand the nature of the occurrence persistent aromas. They are most often caused by bacteria growing in hard-to-reach places, such as a drain hole or drainage channel. Mechanical washing with abrasive soda particles allows you to physically remove plaque in which microbes hide, and the alkaline environment of the substance destroys organic compounds that cause “aroma.” This makes the method ideal for regular preventive maintenance.
Preparing the refrigerator for general cleaning
The effectiveness of cleaning directly depends on the quality of the preliminary preparation. You cannot simply spray the solution on the shelves while there is food inside. The first step will be to completely empty the cameras of their contents. All perishable foods should be temporarily moved to a cool place or to a thermal bag if the process takes longer. Defrosting —a critical step for older models with a drip system, since the ice crust can hide sources of odor.
After defrosting, you need to remove all removable elements: glass shelves, plastic containers for vegetables, freezer drawers and bottle holders. It is more convenient to wash them separately in a bathtub or large basin, where you can use warmer water and scrub more intensively with a brush. The inner walls of the chamber also need to be inspected: sometimes the smell comes from a piece of food that has rolled behind the back panel or into the joints of the plastic.
⚠️ Attention: Never use sharp metal objects (knives, screwdrivers) to chip ice or scrub off dried-in dirt. The plastic of modern refrigerators is very fragile, and one careless movement can lead to the formation of microcracks, in which mold will subsequently settle.
While the removable parts are soaking, start freeing up space. Remove all cans, bottles and packaging. Wipe loose debris from the bottom of the chamber with a dry cloth. Only after the equipment is completely defrosted and free, you can start preparing the cleaning agent. Surface temperature It should be close to room temperature so that the soda solution works as efficiently as possible and does not form condensation immediately.
Preparation of cleaning solution and tools
In order to Clean your refrigerator from odors with baking soda, no need to buy expensive imported products. Regular baking soda (sodium bicarbonate), which is found in every kitchen, will cope with the task better than specialized chemicals. There are two main methods of use: creating a liquid solution for washing large areas and preparing a thick slurry to remove complex stains.
For the main solution, dilute 2 tablespoons of soda in 1 liter of warm water. Warm water helps the substance dissolve faster, but make sure it is not boiling water to avoid damaging the plastic parts. To create abrasive paste mix soda with a small amount of water in a 2:1 ratio until it becomes thick sour cream. This mixture is ideal for cleaning rubber seals and removing yellow deposits from plastic.
- 🧽 Soft sponges —necessary for washing glass shelves and smooth chamber walls to avoid leaving scratches.
- 🪥 Toothbrush —an indispensable tool for cleaning hard-to-reach places, plastic joints and drainage holes.
- 🧣 Microfiber —best for final polishing and collecting moisture without leaving lint.
- 🧤 Rubber gloves —although baking soda is safe, long-term exposure to alkaline environment can dry out the skin of your hands.
It is important to prepare a sufficient amount of clean water for rinsing. Residues of soda on the surface, when dried, can leave a whitish coating that will look untidy. If you have a model No Frost, pay attention to the ventilation system: no water or foam should get there, so you need to wring out the sponge well. Also prepare a separate container for rinsing rags so as not to spread dirt across a clean surface.
Step-by-step instructions: how to wash the internal chambers
The washing process should start from the top shelves and move down so that dirty water does not drip onto already washed areas. Soak the sponge in the prepared soda solution and thoroughly wipe all internal surfaces: ceiling, side walls and rear panel. Pay special attention to the places where the shelves are attached and the guides, where sticky deposits most often accumulate.
The rubber seal around the perimeter of the door is a magnet for odors and mold. Fold it with your fingers to open the folds, and go through it with a toothbrush dipped in soda paste. Don't be afraid to rub, the rubber is resistant to mild abrasives. After treating the entire surface, leave the baking soda for 10-15 minutes to react, and then rinse with clean water. Wipe dry using dry rags.
☑️ Algorithm for washing the chambers
The drainage hole, usually located on the back wall closer to the bottom, requires special attention. This is where water often stagnates and food remains rot. Gently clean it with a cotton swab or a special brush soaked in a soda solution. You can also pour a little solution into it using a syringe without a needle to flush the channel, but this must be done carefully so as not to pour water into the compressor pan.
⚠️ Attention: When cleaning the inside, try not to wet electrical elements, light bulbs and thermostats. Water and electricity are a dangerous combination that can lead to a short circuit or equipment failure.
Cleaning removable elements and accessories
While the internal chambers are drying, let's take care of the shelves and drawers. Glass and plastic can be washed well in the bathroom. Soak them in a warm soda solution for 20 minutes - this will soften dried-on dirt. For boxes made of colored plastic, use only the soft side of the sponge so as not to make the surface matte and rough, since roughness will absorb the smell faster.
If there is a yellow coating or fishy smell left on the plastic parts, use soda paste. Apply it in a thick layer, rub lightly and leave for half an hour. Soda works like a natural agent, drawing out odor molecules from the pores of the material. After this, rinse the paste thoroughly under running water. Make sure that there is no white residue left in the corners of the containers. Adsorbent, drawing odor molecules from the pores of the material. After this, rinse the paste thoroughly under running water. Make sure there is no white residue left in the corners of the containers.
| Part material | Recommended product | Tool | Features |
|---|---|---|---|
| Tempered glass | Liquid soda solution | Soft sponge | Does not like sudden temperature changes |
| Food-grade plastic | Soda gruel | Sponge or cloth | Absorbs odors, requires thorough rinsing |
| Rubber seal | Concentrated solution | Toothbrush | Prone to mold in folds |
| Metal grates | Soda solution | Hard brush | You can rub more actively, but protect from rust |
After washing, give all accessories a full dry at room temperature. Do not place damp shelves back into the chamber, as excess moisture promotes the growth of bacteria and the appearance of new odors. Check every corner of the containers for any residual detergent. Cleanliness of accessories is the key to the absence of foreign odors in the future.
Elimination of persistent odors and prevention
It happens that the refrigerator is washed, but a slight odor still remains. This often happens after storing foods with a strong aroma (fish, garlic, smoked meats) or after a long power outage. In such cases, simple washing may not be enough, and additional deodorizationis required. Soda here is the main character in dry form.
Take several small open containers (bowls, jar lids) and pour dry baking soda into them. Place them on the refrigerator shelves and close the door overnight or overnight. The powder will actively absorb any remaining odor. To enhance the effect, you can add a few drops of essential oil to the soda, but this is for aromatization, not to remove the smell.
Why does the smell return after a week?
If the smell returns after a thorough wash, check the drain pan behind the back panel (bottom of the refrigerator). Dirty water may have flowed there during washing, and now it is evaporating. The source may also be in the ventilation ducts of the No Frost system, where a piece of product could get stuck.
To prevent the appearance of unpleasant odors, follow the storage rules. All products must be packaged in containers or cling film. Regularly, at least once a month, wipe the shelves with a damp cloth and baking soda, without waiting for general cleaning. It is also useful to keep an open box of soda or activated carbon in the refrigerator at all times - they will work as an odor absorber.
⚠️ Attention: If the smell of rot or sewage does not disappear after complete defrosting, washing with soda and replacing adsorbents, there may be a technical problem. Check the condensate drainage system or contact a specialist, as a blockage may have formed in the system that requires professional cleaning.
Common mistakes when cleaning the refrigerator
Many equipment owners, trying to achieve results faster, make mistakes that reduce their efforts to nothing. The most common one is using hot water to wash plastic boxes. Sudden heat can warp the thin plastic, causing it to become brittle and possibly crack when reinstalled. Wash plastic only with warm or cool water.
Another mistake is using fragrances instead of cleaning. Trying to cover up the smell of spoiled food with the fresh aroma of coffee or citrus fruits, you only create an explosive mixture of odors that takes a very long time to dissipate. First, you need to mechanically remove the source of the odor (bacteria and rot) using soda solution, and only then think about aromatization.
- 🚫 Use bleach - can damage the plastic and leave toxic fumes that are absorbed into the products.
- 🚫 Abundance of water —you cannot fill the chamber with water, moisture must be removed immediately with a dry cloth.
- 🚫 Ignore seal —it is in the folds of rubber that mold most often hides - the main cause of the musty smell.
Do not forget about the outside of the equipment. Grease stains and handprints on the door can also give off an unpleasant odor, especially if fish or meat is being fried in the kitchen. Wipe the outside of the case with a soda solution or a special product for stainless steel, if you have a model Inox. Cleanliness on the outside is not only aesthetics, but also hygiene.
Is it possible to wash a refrigerator with soda if it has not been defrosted?
No, this is ineffective and even harmful. If there is ice in the refrigerator, baking soda will not be able to penetrate the contaminants hidden under the crust of ice. Moreover, trying to scrub dirt off the ice will only result in the dirt smearing. First, complete defrosting is required, otherwise you will simply waste time and money.
How often should you wash the refrigerator with soda for prevention?
General cleaning using soda is recommended once every 3-4 months. However, it is worth wiping the shelves with a damp cloth with a light soda solution once every 1-2 weeks, especially if you store food without packaging or often cook at home.
How to replace soda if you don’t have it at home?
If there is no soda, you can use a weak solution of vinegar (1 tablespoon per liter of water) or citric acid. However, vinegar has its own pungent odor, which will take a long time to dissipate. Laundry soap is also suitable, but it must be washed off very carefully so that no sticky residue remains.
Is baking soda safe for plastic refrigerator drawers?
Absolutely safe. Baking soda is a mild abrasive and does not react aggressively with food-grade plastics used in refrigerators (ABS plastic, polystyrene). It does not corrode the material and does not make it cloudy, unlike some aggressive solvents.
What to do if there is a white residue left after washing?
White coating is dried soda. To remove it, just wipe the surface with a damp, clean cloth. If plaque remains in the folds of the seal, use a toothbrush dipped in water to clean the remaining product from the rubber pores.
