As someone who washes my (steel) water bottle at most 1x a week, and drinks ~10-14L of water a week, I've never gotten sick from drinking out of my bottle before.

You can usually tell if the water in your bottle is going bad / filled w bacteria..

Same, except I wash it like once in a blue moon lol.

I have to at least rub the area where I drink otherwise it will smell within less 2 days

I don't usually touch the bottle with my mouth, so I guess that allows for a bit more leeway.
