Health experts say to wash your water bottle every day. I definitely do this, even if I can’t recall the last time I actually washed my water bottle. I must wash it so often, all my water-bottle-washing incidents blend together. It’s involuntary, like breathing. You wouldn’t ask anyone how many times they’ve breathed today, would you?
Just like any other dish, a water bottle needs to be washed. Even if your water bottle looks clean, it’s teeming with mouth bacteria and other particles that need to be vanquished, just like the invisible dirt, sweat, and skin flakes on bedsheets and bras—which I always wash weekly, sometimes.
But even if I didn’t wash my water bottle every day—hypothetically, of course—it only contains water, right? Water is what you use to clean dirty stuff, so in a way, a water bottle is self-cleaning. Like an oven. Or a vagina. For someone who doesn’t ever wash their water bottle (a.k.a. not me), this theory—like a self-cleaning water bottle—would definitely hold water.
