I didn't know about the bacteria issue. Never thought about it really, I wash the food dishes everynight and rinse out the water ones a couple times a day and then run everything through the dishwasher at least once a week.
I don't think I would use bleach either.. I'm sure if you rinse real well it's ok, but I don't know. I'm also real leary of simple green, my experience is that it's really harsh. I had a friend who used to use it to clean things around her house. She started getting sick and the doc said it gone through her skin (no gloves) and tore at her stomach lining or something like that.
