Before you grab for detergents, it is important to understand source of odor. Most often the culprits are:

• 🦠 Bacteria and mold - multiply on the walls, seals and in the drainage hole. Often appear due to leaking packages or forgotten products.
• 🧊 Stale water —liquid accumulates in the tray under the refrigerator or drainage system and begins to rot.
• 🔥 Improper cleaning —if you wash the refrigerator rarely or use aggressive agents (for example, bleach), they destroy the protective layer of plastic, and odors are absorbed more strongly.

Interesting fact: in refrigerators with a system No Frost odor appears less often, but if it does arise, it is more difficult to get rid of it due to hidden air ducts. And in models with drip defrosting (for example Atlant or Biryusa), the main source of “aromas” is the drainage hole, which is often forgotten to clean.

1. Defrosting (for models without No. Frost). If there is ice in the freezer, let it melt. You can speed up the process by placing a pan of hot water inside. Do not break off the ice with a knife - this will damage the evaporator.
2. Removing shelves and drawers. Remove all removable elements and wash them separately in the sink with a soda solution. For glass shelves, you can use glass cleaner.
3. Cleaning the walls and seal. Wipe all internal surfaces with a damp sponge and detergent, paying attention to:
   • Corners and joints;
   • Rubber seal (use a toothbrush);
   • Drainage hole (clean it with a cotton swab dipped in peroxide).
