Are stainless steel water bottles safe?
Let’s just get straight to the point: yes, stainless steel water bottles are completely safe! This is due to the material they’re made of: 304 (also known as 18/8) stainless steel, which is food grade. This material is corrosion-resistant as it’s made from chromium and nickel.

Can you freeze water in stainless steel bottles?
Yes, they can be refrigerated and even frozen. Just make sure that the bottle is not full since water (and most juices) will expand on freezing.
What should you not drink with stainless steel?
Dry ice, carbonated beverages, etc. (These may increase the pressure, causing the contents to blow out.) Milk, dairy-based drinks, fruit juice, etc. (These beverages may spoil, emitting gas that may cause the stopper to break or explode.)
