I've been bouncing back and forth between my "No BPA" plastic water bottle and stainless steel. I like the steel a lot -- I can trust it -- and it keeps water so cold! :)
Sometimes if I leave it closed for a while, it smells like mildew. Obviously because no light or sun gets in. I'm sure this happens to everyone. How do you clean it? Just hot water? Swish a bit of salt, hydrogen peroxide, baking soda?
Let me know what you do.
