Answer:
+ Deodorize

Salt has the ability to absorb odors quite well, and placing a bowl of salt in the refrigerator can help remove unpleasant odors from foods. This makes the space in the refrigerator more fragrant and pleasant.

+ Absorb moisture

Salt also has the ability to absorb moisture, reduce humidity in the refrigerator compartment and prevent water condensation, helping to preserve food better and limit the growth of bacteria and mold.

+ Support food preservation

Placing a bowl of salt in the refrigerator can also help preserve food better. The ability of salt to absorb water helps reduce humidity in the air, thereby keeping food fresh and avoiding water condensation in the bag.

+ Defrosting ice in the freezer

When you adjust the refrigerator temperature too low and maintain it for a long time, a layer of ice will form, closing around the refrigerator wall, reducing the efficiency of cooling and preserving food. If you use a sharp object to pry off this layer of frost, you may cause the refrigerator to explode, which is very dangerous.

You can sprinkle salt directly on the frozen layer of frost in the refrigerator. Salt has the ability to absorb water, so it will effectively reduce the time it takes to defrost the frost in the refrigerator. When the frost has melted, use a clean towel to dry the freezer.

+ Save electricity

Salt can help reduce the formation of frost on the refrigerator wall, thereby helping to maintain cooling efficiency and save energy. By keeping a bowl of salt in the refrigerator for a long time, you can reduce your electricity bill and extend the life of the refrigerator.
