Bleach is corrosive.
I just find it funny people will worry about reusing a plastic water bottle but they will probably drink a steamy hot Starbucks coffee from a paper cup that's covered in WAX. I wonder how long until the people who sell reusable coffee mugs latch onto that one and start that urban myth?
Bleach isn't a suitable solvent for most plastics, especially plastics that they use to make water bottles out of. Bleach may attack the surface and cause stress cracking, but it's not going to dissolve the plastic and allow it to go into the water.
As far as the wax used to line paper cups, it is food grade and safe to eat. If you buy apples and eat them without a significant scrubbing first, you're eating wax. There's even wax in some chocolate candy.
