My conculusion was that I'm safe so long as I don't try to drink boiling water from my Lexan bottle. <img src="/images/graemlins/wink.gif" alt="" />

I don't even using very hot water for cleaning my Lexan bottles, instead I wash them with warm soapy water and rinse them out. Then I sanitize them using water with just a "blip" of chlorine bleach. I transfer the bleach water from bottle to bottle giving each some time to sit.
