Denture cleaning tablets! Why'd I never think of that? That's a winner for sure!

I'm surprised to hear about the issue with freezing metal bottles. I guess since it won't freeze evenly there's that risk, just never thought about it. I might now just put ice in the bottle, then put it back in the freezer... still annoying...
