Refrigerator - the only household appliance that works without interruption 24/7, accumulating inside not only food, but also persistent odors, greasy stains, and sometimes even mold. Baking soda - a cheap, safe and universal product that will cope with pollution no worse than expensive household chemicals. But how to use it correctly so as not to damage the seals, not to scratch the surface and to ensure that all contaminants are eliminated?
This article contains detailed instructions for cleaning No Frost, drip and old Soviet refrigerators using soda, including hidden areas (drainage hole, rubber seals, back wall). And also - a list of mistakes due to which, after cleaning, stains remain or corrosion appears on metal parts.
Why soda is better than household chemicals for the refrigerator
Gels and sprays for cleaning refrigerators often contain aggressive surfactants (surfactants) that corrode rubber sealants and leave a toxic coating on surfaces. Baking soda (NaHCO₃) is free from these disadvantages:
- 🧪 Safe for health - even if soda particles remain on the walls, they will not harm the products.
- 💧 Dissolves grease and limescale due to the alkaline reaction (pH ~8.1).
- 🦠 Kills 80% of bacteria (including E. coli i Salmonella) at a concentration of 2 tbsp. spoons per 1 liter of water.
- 🚫 Does not leave scratches on stainless steel, plastic and glass.
- 💰 It costs 10–15 times less specialized products (a pack of soda - from 30 ₽).
In addition, soda neutralizes odors at the molecular level, and does not mask them like flavoring agents. This is especially important for refrigerators with a No Frostsystem, where air circulation can carry unpleasant “odors” across all shelves.
⚠️ Attention: Do not confuse baking soda (NaHCO₃) with soda ash (Na₂CO₃) or caustic (NaOH)! The last two have a pH of 11–14 and can damage enamel and plastic.
Preparing the refrigerator for cleaning: 5 mandatory steps
Before you start cleaning, the refrigerator must be properly prepared. Skipping any of these steps may result in short circuits, food spoilage, or ineffective cleaning:
Unplug the appliance (unplug the appliance)
Remove all food and shelves (use a cooler bag or bowl of ice)
Check the expiration dates of products - throw out expired ones
Remove all removable elements (drawers, racks, lids)
Prepare the tools: sponges, rags, spray bottle, toothbrush-->
If there is system No Frost, after disconnecting from the network, wait 10-15 minutes until the ice on the evaporator melts naturally. Do not try to scrape it off with a knife or other sharp objects - this may damage the freon tubes.
For models with a drip system (Indesit, Atlant, Biryusa), prepare an additional container to collect melt water from the drainage hole. In some refrigerators (for example Samsung RB30J3000WW), this hole is located under the “crying” wall and can become clogged with food particles.

3 recipes for soda solutions for different types of contamination
The concentration of soda in the solution depends on the degree of contamination and surface material. For daily cleaning, a weak solution is sufficient, but for old stains of grease or mold, a more aggressive composition will be required.
| Type of contamination | Solution recipe | How to use | Exposure time |
|---|---|---|---|
| Light dirt, fresh stains | 1 tbsp. spoon of soda per 1 liter of warm water | Apply with a sponge or spray, wipe with a soft cloth | 2–3 minutes |
| Greasy deposits, sticky spots | 3 tbsp. spoons of soda + 1 liter of water + 1 tbsp. spoon of vinegar (9%) | Apply for 5 minutes, clean with the hard side of the sponge | 5-7 minutes |
| Mold, persistent odors | 4 tbsp. spoons of soda + 1 liter of hot water + 5 drops of tea tree essential oil | Spray, leave for 10 minutes, rinse with clean water | 10-15 minutes |
| Smell of fish/onions/spices | 2 tbsp. spoons of soda + 1 liter of water + juice of ½ lemon | Wipe all surfaces, leave open for 1 hour | 30–60 minutes |
For cleaning rubber seals use a solution of 1 teaspoon of soda per 200 ml of water - a more concentrated composition can dry out the rubber and cause cracking. For stainless steel (external surfaces of refrigerators Liebherr, Bosch) add 1 tbsp to the solution. a spoonful of olive oil - this will prevent streaks.
Step-by-step instructions: how to clean the inside of a refrigerator with soda
Start with the top shelves and gradually work your way down. This way, dirt and drops of solution will not flow onto already cleaned surfaces. For hard-to-reach places (corners, joints), use cotton swabs or a toothbrush.
-
Removable elements: Wash drawers, shelves and grates in the sink with a soda solution (1 tablespoon per 1 liter of water). For plastic parts, you can use the hard side of the sponge, for glass - only a soft rag.
-
Walls and bottom: Spray the solution (3 tablespoons of soda per 1 liter of water) on the surface, wait 5 minutes, then wipe with a microfiber cloth. For old stains, use a paste of soda and water (the consistency of toothpaste).
-
Sealing rubber: Wipe with the solution (1 teaspoon per 200 ml of water) using a cotton pad. Pay special attention to the folds - this is where the most dirt and mold accumulate.
-
Drainage hole: Pour 2-3 tbsp into it. spoons of soda solution (without vinegar!) using a syringe or syringe. Then rinse with clean water.
What will happen if you do not clean the drainage hole?
A clogged hole leads to water accumulation under the vegetable boxes. Moisture becomes a source of mold and unpleasant odors, and can also cause corrosion of metal parts of the compressor.
-
Drying: Wipe all surfaces dry with paper towels or a clean rag. Leave the door open for 30–60 minutes for ventilation.
For refrigerators with the function Antibacteria (for example, LG GB-B459SLQZ) after cleaning with soda, it is recommended to turn on the disinfection mode (if provided by the manufacturer). This will enhance the effect and prolong freshness.
⚠️ Attention: Do not use abrasive powders or metal brushes to clean aluminum the back walls (in models Atlant, Stinol). Soda in dry form can scratch soft metal, which will lead to corrosion.
Cleaning external surfaces: stainless steel, plastic, glass
The external panels of the refrigerator also need care - dust, greasy splashes and fingerprints settle on them. For different materials, use different approaches:
- 🔄 Stainless steel (Samsung RS62R5001M9, Liebherr CNef 4815): wipe with a soda solution (1 tablespoon per 1 liter of water) in the direction of the “fibers” of the metal, then polish with dry microfiber.
- 🧴 Glossy plastic (Indesit DF 5200 W, BEKO GNE114620X): use a solution with the addition of 1 tbsp. spoons of liquid soap - this will prevent streaks.
- 🖼️ Glass doors (Gorenje RK 6292 AW: apply soda slurry for 2-3 minutes, then rinse with vinegar solution (1:1 with water) for shine.
- 🔌 Radiator grill (behind the refrigerator): vacuum, then wipe with a damp cloth and baking soda (do not fill with water!).
For displays and touch panels (in models Samsung Family Hub) use a solution of 1 teaspoon of soda per 200 ml of distilled water. Apply it to a rag, not to the screen, to avoid moisture getting inside.
5 mistakes that ruin your refrigerator after cleaning with soda
Even such a harmless product as soda can be harmful if used incorrectly. Here are the most common mistakes and their consequences:
-
Use of hot water (above 50°C) for the solution. This leads to deformation of plastic shelves and rubber seals, especially in refrigerators with thin walls (Minsk, Nord).
-
Leaving soda slurry on metal longer than 10 minutes. Alkali can cause oxidation of aluminum parts (for example, in models Atlant XM-4021-000).
-
Cleaning with soda. chlorine (for example, adding “White”) This combination releases toxic gas that can damage the compressor and leave a persistent chemical odor.
-
Neglect of drying. Wet surfaces become a breeding ground for bacteria, and water in the drainage hole causes rust on the pan.
-
Cleaning the freezer without defrosting. Ice and snow reduce the effectiveness of soda, and attempts to scrape them off with a knife can cause damage. evaporator.
If after cleaning there are white stains on the walls, wipe them with a vinegar solution (1 tablespoon per 1 liter of water). To remove the smell of soda (if you overdo it with the concentration), put an orange peel or a bag of vanilla in the refrigerator for 12 hours. sugar.
How often to clean a refrigerator with soda: cleaning schedule
The frequency of cleaning depends on the intensity of use of the refrigerator, the number of people living in the house and the type of food stored in it. Here is the optimal schedule:
| Type of cleaning | Frequency | What to do |
|---|---|---|
| Weekly | 1 time every 7 days | Wipe the shelves and walls with a weak soda solution (1 teaspoon per 1 liter of water), check expiration dates products. |
| General | 1 time every 3 months | Complete defrosting, cleaning of all removable elements and drainage hole, disinfection of seals. |
| After a leak | As needed | Immediate cleaning with soda and vinegar (3:1), drying for 2-3 hours. |
| Before a long departure | 1-2 days before shutdown | Wash all surfaces, leave the door ajar, put a bag of silica gel inside. |
For families with children or allergy sufferers, it is recommended to carry out general cleaning once every 1–1.5 months. In refrigerators with a system No Frost (Electrolux ENN2853AOW, Haier C2F636CWG), you can reduce the frequency of cleaning the drainage hole to once every 6 months - thanks to automatic defrosting, less accumulation occurs there. dirt.
⚠️ Attention: If there are pets in the house, after cleaning with soda, thoroughly rinse the solution from all surfaces - the remaining alkali can irritate the mucous membranes of pets.
FAQ: Answers to frequently asked questions
Is it possible to clean a refrigerator with soda? an air ionizer (for example Panasonic NR-BN30A1)?
Yes, but after cleaning you need to turn on the ionization mode for 2-3 hours to remove residual soda from the air. Also avoid getting the solution on the ionizer vents.
Will soda help remove the smell of rotten eggs or fish?
Soda neutralizes odors, but for persistent “aromas” it is better to combine it with vinegar or lemon juice. After cleaning, place a plate of ground coffee in the refrigerator for 12 hours - it will absorb the remaining odor molecules.
Is it possible to use soda to clean a refrigerator with a water dispenser (Samsung RF23J9011SG)?
Yes, but avoid contact with soda solution into the water supply system. Wipe the dispenser separately with a damp cloth, then rinse with clean water, passing 1-2 liters through it.
How to replace soda if it is not at hand?
Alternatives: citric acid (1 tablespoon per 1 liter water), ammonia (1 teaspoon per 200 ml of water) or hydrogen peroxide (3%). But these products are less safe for seals and can leave an odor.
Why did a metallic taste appear in the refrigerator after cleaning with soda?
This means that the solution got on the aluminum parts (for example, the back wall) and caused oxidation. Rinse the refrigerator with clean water, then wipe with a solution of vinegar (1 tablespoon per 1 liter of water) and well. dry.
