Why the refrigerator starts to smell bad: 5 main reasons

- 🍳 Spoiled food - even a small piece of meat or fish lost on the back shelf can become a source of a sickening odor.
- 🦠 Bacteria and mold - a humid environment and food debris create ideal conditions for the proliferation of microorganisms, especially in the drainage hole and on the rubber seal.
- 🧊 Stale water — in models with drip defrosting, liquid can accumulate in the pan and “bloom.”
- 🧀 Products with a strong odor — cheeses, smoked meats, spices and garlic “impregnate” plastic if stored without sealed packaging.
- 🔧 Technical faults —if the smell is similar to burning or chemicals, the problem may be in the compressor or freon leak.

Step-by-step instructions: how to clean the refrigerator from odors
For effective cleaning, follow this algorithm. It is suitable for all types of refrigerators, including Samsung, LG, Indesit and Atlant with systems No Frost and drip defrosting.
☑️ Proper cleaning of the refrigerator
Preparation: Turn off the refrigerator, take out all the food (preferably in a thermal bag) and remove the removable elements (shelves, drawers, racks). If the model has a function
Vacation Mode(for example, y Bosch or Liebherr), activate it - this will speed up defrosting.Defrosting: If there is ice in the refrigerator, wait until the refrigerator is completely frozen. defrosting. You can speed up the process by placing a bowl of hot water (but not boiling water!) in the chamber. In models with No Frost this step can be skipped.
Washing removable parts: Wash the shelves and drawers in warm water with added product (for example, «Sano»). For stubborn stains, use a soft sponge or toothbrush. Wash glass shelves separately, avoiding temperature changes.
Cleaning the internal surfaces: Apply detergent to the walls, bottom and ceiling of the chamber. Pay special attention to:
- 🧲 Sealing rubber —this is where most bacteria accumulate.
- 🕳️ Drainage hole —clean it with a cotton swab dipped in vinegar.
- 🔄 Ventilation grilles (in models No Frost) - dust and grease clog them, impairing air circulation.
Drying and deodorizing: Wipe all surfaces dry with microfiber with a rag. Place absorbents (soda, charcoal, coffee beans) on the shelves for 12–24 hours. Plug in the refrigerator and let it run empty for 1-2 hours.
If the smell remains, repeat the procedure, but use instead of detergent ammonia solution (1 tsp per 1 liter of water). It neutralizes even persistent “aromas” of rotten meat or fish.
How to remove persistent odors: fish, onions, mold

- Put on shelves orange or lemon peels for 2-3 days.
- Use ozonizer (if available) - it decomposes organic molecules that cause odor.
🧅 The smell of onions or garlic
Onions and garlic release sulfur compounds that are absorbed into the plastic. To neutralize them:
- Rinse the refrigerator a solution of soda and hydrogen peroxide (2 tablespoons of soda + 1 tablespoon of peroxide per 1 liter of water).
- Place on shelves an open jar of ground coffee for 12 hours.
- Wipe the walls diluted iodine (5 drops per 1 liter of water) - this will kill bacteria.

Mold not only smells, but is also dangerous to health. You need to fight it radically:
- Remove all visible colonies of mold with a cotton pad soaked in vinegar.
- Treat the surfaces Belizna solution (1:10 with water), then rinse thoroughly.
- Dry the refrigerator hairdryer (cold air!) for 30 minutes.
- Place on shelves sachets with silica gel (those that are put in shoe boxes).
If mold appears again, check drainage hole - most likely it is clogged and water does not go into the pan.
What to do if the smell returns?
If after cleaning the smell appears again, the problem may be a malfunction of the defrosting system or a clogged drain tube. In this case, only professional cleaning or repair will help.

- 🧊 Humidity control: In models without No Frost regularly wipe off condensation. Use desiccants (for example, "Silica gel").
- 🔍 Checking the seal: Once a month, clean the gum with a soda solution and lubricate glycerin (will extend service life).
- 🌡️ Temperature mode: Maintain
+4…+5°Cin the main chamber and-18°Cin the freezer. At higher values, food spoils faster.
