The correct way to use the thermos cup that we ignore

How to use the thermos cup correctly?
Cleaning
After buying the thermos cup, I suggest you read the instructions and use the thermos cup correctly. The cup will last a long time.

1. Friends, if you buy a thermos cup that can be completely disassembled, it is recommended to wash it all with warm water first, and finally pour boiling water into it and wash it again.
2. For cup stoppers, etc., if they are plastic parts and silicone rings, do not use boiling water to scald them. It is recommended to sprinkle them with warm water.
3. For those who are worried, you can put one or two drops of vinegar in warm water, pour it into a cup, leave it uncovered for half an hour, and then wipe it with a soft cloth.

If there are many stains in the thermos cup, friends may want to squeeze some toothpaste and wipe it back and forth on the inner wall of the vacuum, or use potato peels dipped in toothpaste to wipe.

Note: If it is a stainless steel thermos cup, do not use detergent, salt, etc. to clean it, otherwise the inner tank of the thermos cup will be damaged by detergent and salt. Because the liner of the thermos cup has been sandblasted and electrolyzed, the electrolyzed liner can avoid physical reactions caused by direct contact between water and stainless steel, and salt and detergent may cause damage to it.
When cleaning the liner, you need to wipe it with a soft sponge and soft brush, and keep the liner dry after wiping.

Usage
1. Filling too little or too much water will affect the insulation effect. The best insulation effect is when the water is filled 1-2CM below the bottleneck.
2. The thermos cup can be used to keep warm or cold. When keeping warm, it is best to add a little hot water first, pour it out after a few minutes, and then add boiling water. In this way, the heat preservation effect will be better and the time will be longer.
3. If you want to keep it cold, you can add some ice cubes, so the effect will be better.
