I just ordered two Klean Kanteens and I think they'll be great, as they're stainless steel and lightweight. Not that mold won't grow in SS, but I like the fact that there's no plastic.

Bleach them. I have terrible mold allergies so I avoid it like the plague. My understanding is that it's not that good for anyone and besides it looks gross!
