The rapid development of the vacuum flask market has led to a variety of insulated cups at different prices. Even if you can't tell which stainless steel mug is of poor quality, one thing you remember is that it's cheap and not good. I spent a lot of money to buy a stainless steel mug that I like, how can I get the most out of my energy? As long as consumers can do the following, stainless steel vacuum flasks can generally be used for a long time:

a. Because the cup cover and the middle bolt are plastic parts, do not put them in boiling water to cook or disinfect the cabinet and microwave oven, otherwise it will cause deformation.

b. When the cup is not in use, remember to dry it upside down, or put it in a ventilated place to dry, so that the life of the cup will last for a long time.

c. The vacuum flask is vacuum insulated and has good sealing performance. Bumping and falling will affect its insulation effect.

d. Keep in mind that the milk, Chinese medicine, carbonated drinks, and objects or liquids that are very irritating or corrosive are not allowed. (a, milk, juice, dairy products containing protein, prone to spoilage for a long time; b, soda, carbonated drinks, pressure will rise easily ejected; c, lemon juice, sour plum juice and other acidic drinks, will cause poor insulation).

e. the newly bought cup, first rinse with water, then use a cup brush to clean (the cup brush should be soft, such as a sponge brush, do not use a hard brush to brush the stainless steel liner), then pour 90% into the cup The hot water, cover the lid, soak it for a few hours, then you can use it with confidence.
