Use soap and warm (running, if available) water. Wet hands and add soap. Rub wet hands strongly with soap outside running water more than 10 seconds. Rub all parts of the hands again and again. Clean all dirt under fingernails. Then rub hands under running water again and again to take off all soap. Dry hands using a clean cloth or paper. Use moisturizing lotion so hands do not dry if the hands are being washed many times every day.
