Use any temperature water, it does not have to be hot and whatever type of soap, it does not have to be antibacterial. Scrub your palms, the backs, around your wrists, around your thumbs, in between your fingers and under your fingernails for the recommended 20 seconds. Rinse thoroughly and dry with a clean paper towel or towel, the towel does not have to be sterile, just not soiled. Then use the paper towel to turn off the water.
