How long can you keep water in a stainless steel bottle? Week-old water is safe to drink as long as the bottle is clean and sealed properly, and stored in an area where there is no direct sunlight. Moreover, you can also store water in a tightly sealed stainless steel bottle for up to 6 months.
What can you not put in a stainless steel bottle? Stainless steel water bottles are versatile when it comes to temperature but there are some drinks that you should not put in them. Three of those drinks are lemonade, hot tea, and hot milk. These drinks can either damage your water bottle or cause bacterial buildup inside.
Can stainless steel water bottles get mold? This is because mould and mineral deposits collect on any surface and they have decided the inside of your bottle is a pretty cool place. This is perfectly normal and no reason to fret – stainless steel is non-porous so there is nowhere for bacterial or fungus to grow, it simply needs to be removed.
Is week old water safe to drink? Once again the answer is yes, according to Krogh. “The taste may be a bit flat but it isn’t harmful,” he says. Even without being capped, water is potable for weeks or months as long as it hasn’t been polluted by dirty fingers or spit which is full of bacteria.
