The following drinks are not allowed to use thermos vacuum insulated stainless steel water bottles
Acidic drinks. If the inner liner of the vacuum insulated stainless steel water bottle is made of high manganese and low nickel steel, it can not be used for acidic drinks such as fruit juice or carbonated drinks. This material has poor corrosion resistance and is liable to precipitate heavy metals when it is acidic. Long-term acidic drinks may damage human health.

However, acidic substances in dairy products will react with stainless steel, which is not conducive to human health. Milk microorganisms in higher temperatures will also accelerate the reproduction, so that milk spoilage, deterioration, abdominal pain, diarrhea and other discomforts.
Tea. When many middle-aged and old people go out, they like to pour hot tea on their vacuum insulated stainless steel water bottles, which will not get cold in a day.
