My od doc used to recommend to use it for the first cleaning and not agin unless it was a deep puncture wound. If it was he wanted it cleaned twice a day with it so it would heal form the bottom. Worked great on some severe dog bites down to the bone.Lucky_P":168ta8ie said:Val,
In general, H2O2 is for flushing/cleaning fresh, or contaminated wounds - not older, clean, healing wounds.
A good rule of thumb, with regard to not impeding wound healing is that you should not put anything in/on a healing wound that you wouldn't want to put in your own eye. In other words, if it burns or hurts, it's not good.
