– 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

Answer 1

I drink out of the same water bottle at work for weeks. I fill and empty it 3-4 a day so the water doesn’t sit any longer than overnight. No problems.
