Hello, Soccerstar3071. The reason why we wash our hands with soap and water when we have a wound is to not transport the amount of bacteria from our hands to the wound. With that being said, there are many antibacterial soaps that can help kill the bacteria on your hands, so the wound will not be infected. If you do not use water, use hydrogen peroxide. Hydrogen peroxide helps bubble and prevent any bacteria from spreading to the wound. Both of these are key for the healing process of the wound to take place. I hope I have helped you!! Have a great day.
