Hygiene without running water, food grade H202 diluted to 3%. During hurricane charlie I picked up a super bacteria from the flood waters, due to a hole in my waders. Tropical storm fay came through here, and there was worse flooding than charlie. Canals caved in, and a large amount of water was backed up, once again I had to be out wading in it. This time when I was done I sprayed down with h202, I had no problems. It left me feeling clean, and disinfected. Before a hurricane be sure and do your laundry, it is very hard to tell when the next time you get to wash clothes will be.
