I saw an expose on water bottles. I used to keep a 1 gallon water bottle (from walmart) and drink from it everyday. I’d wash it several times a week, with hot water and soap. But apparently that is not good enugh as deadly bacteria can still accumulate. They did tests on different situations and leaving a bottle out and not washing it for a couple days can accumulate sometimes toxic levels of bacteria. Only when they washed it in the dishwasher were the levels acceptable.
Just curious if anyone uses a gallon bottle or how do you clean them? I have since just get a gallon of water from the store and refill it once.
