Some people love hydrogen peroxide but I am not a big fan. It has never done much for me. Also, some of the research on hydrogen peroxide involves much stronger pharmaceutical mixtures, not the 75 cent brown bottle kind. heh. Even so, I have tried that stuff on a few outbreaks and it seemed to actually make them worse. :-0
I think something like lemon juice would probably be more effective as a pre-contact rinse than hydrogen peroxide.
