Effective handwashing involves several key steps to ensure the removal of germs:
Wet hands with clean, running water (warm or cold). Apply soap and lather by rubbing hands together, covering all surfaces (backs of hands, between fingers, under nails). Scrub for at least 20 seconds, about the time it takes to hum the "Happy Birthday" song twice. Rinse hands thoroughly under running water. Dry hands using a clean towel or air dryer. Use a towel to turn off the faucet if available.
