I have this water bottle that I use at home which I use constantly. I refill it with tap water frequently but every time I open the cap, I see this white residue gathered . What is that and is it safe for me to use that bottle again?

It’s probably just your water being too hard. That means that it has a lot of calcium and magnesium. When it precipitates out it leaves those behind. It’s safe to drink.
