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

751 views

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

I scrolled a few comments deep and didn’t see any mention of the fact that you may be filling it with tap water which has a trace amount of chlorine in it. Water in your municipal water system not only has to treat the water from the source, but it also has to keep it treated until it reaches its destination through all the pipes it travels. Refilling your bottle introduces clean chlorinated water to your bottle and helps to keep the growth of algae and mildew at bay.
