Tips for prolonging the service life of vacuum flask

1. Because the cup lid and middle stopper are plastic parts, do not put them in boiling water or sterilize them in a sterilizer or microwave, otherwise they will cause deformation.

4. Keep in mind that the thermos cup must not be filled with milk, Chinese medicine, carbonated drinks, and irritating or corrosive objects or liquids. (A. Milk, fruit juice, and dairy products contain protein and are easy to decay for a long time; b. Soft drinks and carbonated beverages will increase in pressure and easy to spurt; c. Acidic beverages such as lemon juice and plum juice will cause poor insulation).

5. Rinse the newly purchased cup with clean water, and then clean it with a cup brush (the cup brush should be soft, such as a sponge brush, never use a hard utensil to brush the stainless steel inner container), and then pour 90% into the cup Cover the cup with the hot water, soak it for a few hours and then pour it out, you can use it with confidence.
