method 1: freezing in the refrigerator will consume a lot of electricity, and the cold room will take up a lot of space. At this time, we have to melt the ice in the refrigerator first, and then put a layer of cooking oil on the inner wall of the refrigerator's freezer, which can effectively prevent the freezer from freezing. It is best to use vegetable oil, which has a low freezing point. If you don't use oil, it is also possible to use plastic wrap.

Method 2: Turn off the power supply of the refrigerator, put a large bowl of warm water (don't use boiled water) in the freezer, and change the water after about 1 minutes. This method can melt the ice in the freezer more quickly. This method is relatively slow and takes a long time to take effect, so the effect is not obvious when used.

method 3: after the ice in the refrigerator melts, dry the ice water with a clean cloth. After cleaning, you can stick the plastic film on the inner wall of the refrigerator. Next time we remove the plastic film from the inner wall of the refrigerator, it will be done. Plastic film mainly plays a role in separating food from refrigerator wall.

refrigerator defrosting:

1. The best time to defrost the refrigerator is when there are few things in the refrigerator. At this time, we need to take out the food in the freezer.

2. Unplug the power of the refrigerator, or turn off the power switch of the refrigerator before unplugging the power of the refrigerator.

3. Take out the drawer in the freezer of the refrigerator. At this time, you can also clean the drawer timely.

4. Wipe the frosted parts repeatedly with a wet towel. After wiping off the frost, dry the water in the refrigerator to speed up defrosting, so as to avoid food deterioration. Remember not to defrost forcefully.

5. After defrosting in the freezer of the refrigerator, dry it with a rag.
