Is it safe to drink water in a stainless steel cup?
There is no harm in making cups out of stainless steel. This kind of cup usually has good fall resistance and safety, and the heat preservation effect is usually good, so we have no problem drinking water with this kind of cup.
However, it should be noted that when we usually use stainless steel cups, it is best not to use them to hold coffee, fruit juice, carbonated drinks and so on. To prevent some substances in stainless steel from being harmful to the body because of the precipitation of these drinks.
At the same time, when we buy stainless steel cups, we should choose cups made by regular manufacturers, and we can't clean them with bleaching powder and soda, because these things may react with substances in stainless steel.
