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

Like everyone else says just wash it every few days or so with hot soapy water. Don’t be like u/yoinksboy
