Query: Good to keep on hand incase of emergency

I read that before surgery to use Hibiclens Skin Cleanser on the said area everyday for a week before hand. Hibiclens has proven effective in fighting MRSA, it also fights other types of staph infections, the flu and other viruses. Apparently, it provides protection for up to six hours after use and is not diluted by blood, water or sweat. I would totally recommend.
