What water bottles are completely free from the problem of weird chipping/shavings of the material which could put material in the water, even when dropping it or when using Bottle Bright tablets?

if you're worried about microplastics, consider a stainless steel bottle. Clean Canteen is a solid brand that doesn't put plastic films on the inside.

but I've only had a 'problem' with rather old bottles cracking (crazing, technically,) from age. Bottle Bright might be more harsh and prematurely aging your bottle if you consistently have a problem. I just use warm water and a scrubby somewhat regularly.

I have a stainless steel bottle, 40oz. I have never seen what you are asking.

Metal, glass or ceramics are all fine as long as you fill them yourself with tap water. Bottled water from the store often contains microplastics that got in there during the filling process so the container material isn't the only thing to consider.

Been using them for 15 years; the bottles get a few dents in them, but I’ve even been able to hammer most of those out.

Haven’t used a plastic water bottle since the early 90s.

Any bottles that are not plastic. So glass or metal.

What about Glass Bottles?
