Wet your hands with warm running water and apply a small amount of soap.
Rub your hands together to create a lather with the soap. Cover all of your hands and your wrists with the lather. Rub your hands together for 15 to 20 seconds (try counting slowly to 20 if you don't have a clock nearby).
Rinse your hands in warm, running water.
Use a paper towel or air dryer to dry your hands. Avoid cloth towels that have been used by several people.
Use a paper towel to turn off the faucet and open the door to a public restroom so you avoid contact with an unclean surface.
