> I don't think there's a way of killing microbiota that creates no pressure for resistance, that's just evolution. In order for evolution to function[1], there needs to be differential survival. That is to say, some variants of bacteria must survive at greater or lesser rates than other variants. For something as strong as bleach, given sufficient concentration and working time, it's not clear to me that that effect exists. My understanding is that it's so powerful and it's means of action is so robust that is just kills everything equally. --- 1. Yes, technically evolution never stops and always functions. I guess a more precise way to word that is: in order for there to be an observable evolutionary effect.
