The refrigerator is one of the most essential household appliances in every home, and while we all think there is no wrong way to use it, there are several common mistakes that can affect its efficiency and the safety of the food we store in it. 

I was curious, did some research and gathered some of these mistakes, in case you didn't know them (like me) to correct them!

Overloading: If you overload the refrigerator, think again! This can block the air ducts, restrict airflow, and prevent proper cooling of the entire interior. This can lead to increased energy consumption and food spoilage.

Underloading: On the other hand, having the refrigerator too empty can also be inefficient. Refrigerators need "thermal mass" (i.e. objects inside) to efficiently maintain low temperatures. Completely empty spaces make the refrigerator work harder to cool nothing.

Incorrect temperature settings: Setting the temperature too high can lead to food spoilage, while setting it too low can cause unnecessary energy consumption and freeze items that should not be frozen. The ideal refrigerator temperature is between 3°C to 5°C.

Uncovered food: Leaving food uncovered in the refrigerator can lead to odor transfer and cause faster spoilage due to exposure to air. You should always use airtight containers or plastic wrap to cover it adequately. 

Cleaning: Neglecting regular cleaning of the refrigerator can lead to the accumulation of food residues and bacteria. It is recommended to empty and clean your refrigerator very well at least every 3 to 4 months.

Storing hot food: Placing hot food in the refrigerator can temporarily increase the internal temperature, resulting in more effort needed to bring it to the correct temperature. This causes the refrigerator to work more, thus increasing power consumption. So let the food cool to room temperature before putting it in the refrigerator.

Water filters: For refrigerators with built-in water dispensers and ice makers, replacing the water filter should be done as recommended by the manufacturer to ensure clean water and proper operation.

Storage organization: Incorrect placement of items in the refrigerator can lead to spoiled food and inefficiency in their preservation. For example, milk should not be stored in the door, as the temperature there is higher compared to the main shelves!

Raw and cooked foods: Storing raw meat, poultry, or seafood on shelves above ready-to-eat or cooked foods can cause contamination if they drip liquids. It is good to store raw meats on the lower shelf or in a separate bin.
