So, i used to have a water bottle with no straw where you just directly drink from it, and i just used to rinse like, weekly, maybe? And wash it once a month or every two months (pls don’t judge me for this, lol) but my gf recently gifted me an owala, and i saw that they are common to grow mold if you don’t take care of them properly, so how often should i be washing it? How often do you guys wash yours? I only drink water from it so why would it be dirty? Omg idk am I disgusting? LOL 😭
