– Why is it bad to use my water bottle for multiple days without washing it?

Question

I either drink it all or I dump it and put fresh water in. What are the risks if I don’t wash it? It’s just me drinking out of it. I’m talking days and days like why ever wash it if it’s just me?

Edit: Clarified the amount of time without washing

If you’re cycling through the water every day, then not a big deal. But you don’t want it to sit stagnant for any length of time.

I just got back from 2 weeks vacation and left my water bottle about half full on my desk. When I opened it made the “pssht” sound of releasing gas and smelled like death. It’s currently getting sterilized with bleach. And that was just filtered tap water in it, nothing else.
