How to clean the newly bought thermos cup

1. After buying a thermos cup, read the instruction manual first. Generally, there will be instructions on it, but many people don’t read it, so many people can’t use it correctly, and the heat preservation effect is not good. Open the lid of the thermos cup, and there is a plastic water bottle stopper inside, which is mainly for sealing and the key to heat preservation. Rinse with some cold water first, then press the button to let the water run out of the cork. This will remove some of the dust inside.

2. Some thermos cups may contain polishing powder. Therefore, after the first wash, add an appropriate amount of neutral detergent to wash with warm water, and rinse with clean water after washing.

3. As you can see, there is a rubber ring inside the lid similar to a bottle stopper, which can be removed. If there is a smell, you can soak it in warm water for a while. (Remember: do not cook in a pot); there is a silicone ring that seals water inside, it is recommended to take it out and clean it, as there is usually thick dust on it.

4.Do not use hard objects to wipe the surface of the thermos cup, which will damage the silk screen or transfer printing on the surface. Do not soak for cleaning. When using it, put a small amount of boiling water first, then pour it out, and then put it in boiling water for a better heat preservation effect. Putting it in ice water can still maintain the original cold effect within 12 hours. Plastic parts and silicone rings cannot be scalded with boiling water.
