– 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

Be sure to let it dry out completely every so often. And remove the rubber o-ring in the cap and clean it. That’s where gunk starts.
