A refrigerator is not just a household appliance, but a real “keeper of the freshness” of your products. But even the most modern model Samsung RB37A5200SA or LG GA-B459SLGL over time accumulates persistent odors, greasy stains and bacterial plaque. Many housewives prefer aggressive household chemicals, not suspecting that baking soda it copes with pollution no worse - it is absolutely safe for health and does not leave toxic fumes.
In this article we will look at why soda has become No. 1 in caring for refrigerators (including models with a system No Frost), how to properly prepare a solution for different types of dirt, and what to do with stubborn stains from sauces or fish. And also - a unique deodorizing method with soda and activated carbon, which is used by professional cleaning services.
Why soda: 5 scientific facts about its properties
Baking soda (sodium bicarbonate, NaHCO₃) is not easy a folk remedy, and a substance with proven effectiveness against:
- 🦠 Bacteria (including Salmonella and E. coli - research from the University of Georgia, 2018)
- 🧂 Mineral deposits (dissolves limescale better vinegar)
- 🧪 Acidic contamination (neutralizes odors of fish, onions, spices)
- 🛡️ Mold (prevents the proliferation of spores on seals)
The key advantage of soda over chemistry is its pH-neutrality (level 8.1). This means that it does not corrode rubber seals (unlike vinegar) and does not leave scratches on stainless steel (like abrasive powders). And soda is 3 times cheaper than specialized products like Topperr 3101 or Sano Refrigerator Cleaner.
Preparation of the refrigerator: what needs to be done BEFORE washing
The mistake of 80% of users is to start cleaning with a wet rag without preparing the equipment. This leads to short circuits (if water gets on thermostat) or food spoilage. Follow the checklist:
Turn off the power (unplug!)
Remove all food (use a cooler bag)
Remove shelves and drawers (wash them separately)
Check the drain hole on the back wall
Place towels under the bottom (to collect condensation)-->
Pay special attention sealing rubber. Up to 70% of all bacteria accumulate in its folds (data from microbiologists from Journal of Food Protection). If the rubber is covered with black dots, this is mold, and it needs to be treated with a slurry of soda and hydrogen peroxide (proportions 2:1).
⚠️ Attention: If your refrigerator is equipped with a system Total No Frost (for example Bosch KAN92VI30R), DO NOT use hot water to clean the back wall - this may damage the evaporator. Optimum solution temperature: 30–35°C.
Recipes for soda solutions for different types of contamination
There is no universal recipe: different proportions are needed for grease, limescale and mold. The table below contains proven combinations for refrigerators of any brands (Indesit, Atlant, Liebherr etc.):
| Type of contamination | Solution recipe | Exposure time | Additional ingredients |
|---|---|---|---|
| Fatty stains (from meat, sauces) | 3 tbsp. l. soda + 1 liter of warm water | 5–7 minutes | 1 tsp. dishwashing detergent |
| Smell of fish/onion | 2 tbsp. l. soda + 0.5 l of water + 5 drops of lemon juice | 10–15 minutes (cover with a towel) | Lemon zest (for aroma) |
| Mold on the seal | Soda slurry (soda + water 1:1) | 20 minutes | Toothbrush for cleaning folds |
| Limescale (on glass shelves) | 1 tbsp. l. soda + 1 tbsp. l. vinegar + 200 ml of water | 3–5 minutes (rinse off immediately!) | Microfiber cloth |
For models with air ionizer (for example, Panasonic NR-B57V1) after cleaning with soda, you must turn on function Eco Navi for 2-3 hours - this will speed up the neutralization of residual odors.
Step-by-step instructions: how to clean a refrigerator with soda
The cleaning algorithm depends on the type of refrigerator. For classic models (Birusa 130, Stinol 102) and inverter (Hitachi R-B400P7MS) the procedure will be different. Let's consider a universal method:
- Applying the solution: Soak a soft sponge in a soda solution (see table above) and wipe all surfaces, starting with the top shelves. For vertical walls, use a sprayer.
- Processing the seal: Apply soda slurry to the gum, rub with a toothbrush and leave for 10 minutes. This will remove up to 95% of bacteria.
- Cleaning the drain: Pour 50 ml of soda solution (1 tbsp per 100 ml of water) into the drain hole and rinse with a syringe.
- Washing the shelves: Soak the removable elements in a bowl of soda (2 tablespoons per 5 liters of water) for 15 minutes, then wipe with a microfiber cloth.
- Drying: Wipe all surfaces dry (humidity over 40% promotes the growth of bacteria). Use paper towels for hard-to-reach places.
For refrigerators with water dispenser (for example, Samsung RF23HCEDBSR) additionally rinse the supply tube: pass 1 liter of soda solution through it (1 tsp per 1 liter of water), then 2 liters of clean water.
What to do if the soda did not cope with the smell?
If the smell remains after cleaning with soda, the reason may be:
1) Contamination of the drainage system (deep cleaning is needed tubes)
2) Mold under the plastic panels (disassembly required)
3) Old filter (in models with carbon filters, for example, Whirlpool ART 9810)
In these cases, contact a service center or use an ozonizer (rental costs ~500 rubles/day).
What NOT to do when cleaning with soda
Even such a harmless product as soda can cause harm if used incorrectly. Here are top 3 critical mistakes:
⚠️ Attention: Never mix soda with chlorine-containing products. means (for example, White) - this releases toxic gas chloraminewhich damages the lungs. Symptoms of poisoning: coughing, burning in the eyes.
- 🚫 Use aluminum dishes to prepare the solution - soda reacts with aluminum, forming dark spots.
- 🚫 Leaving the soda slurry on the stainless steel for longer than 10 minutes - this can cause tarnishing of the surface (relevant for models Liebherr CNef 4815 with metal facades).
- 🚫 Wash the freezer with soda at temperatures above +10°C this will speed up the melting of the ice and can lead to leaks.
If your refrigerator has a system Twin Cooling Plus (as in Samsung RB34T602CSR), after cleaning with soda, be sure to run the function CoolSelect Zone on the mode Soft Freezing - this will restore the optimal microclimate in the chambers.
How often to wash a refrigerator with soda: care schedule
The frequency of cleaning depends on the intensity of use and the type of refrigerator. Here are the manufacturers' recommendations:
- 📅 Families with children (the refrigerator opens 20+ times a day): once every 3-4 weeks.
- 📅 For refrigerators s
No Frost: once every 2 months (due to air circulation, contaminants accumulate faster). - 📅 If a lot of fish/meat is stored: once every 2 weeks (using a soda-lemon solution).
- 📅 For office refrigerators (Midea MRF-49N): weekly (due to frequent opening of the door).
For models with antibacterial coating (for example, Hisense RB-390N4WB1), it is enough to wipe the shelves with a soda solution once a month - the coating itself suppresses up to 99.9% of bacteria.
Alternative cleaning methods: when soda does not help
Although soda copes with 90% of contaminants, there are cases when other means are needed:
| Problem | Alternative to soda | Example of application |
|---|---|---|
| Old fat (more than 6 months) | Dishwashing gel Fairy Platinum + soda (1:1) | Apply for 30 minutes, rinse with hot water |
| Mold in the drainage hole | Hydrogen peroxide 3% + soda (gruel) | Apply for 1 hour, clean brush |
| Rust on metal shelves | Citric acid (2 tablespoons per 1 liter of water) | Wipe, rinse after 5 minutes |
| Burning smell (after overheating) | Activated carbon (5 tablets per shelf) | Leave for 48 hours |
For refrigerators with plasma air purification (Sharp SJ-FX720V-SL) after using alternative means, you must start the mode Plasmacluster Ion for 60 minutes - this neutralizes chemicals leftovers.
FAQ: Answers to frequently asked questions about cleaning the refrigerator with soda
