1. Wetting hands with clean, running water (warm or cold), turning off the tap, and applying soap. 2. Lathering hands by rubbing them together with the soap, including the back of hands, between fingers, and under nails. 3. Scrubbing hands for at least 20 seconds. 4. Rinsing hands well under clean, running water. 5. Drying hands using a clean towel or air dryer.
Using an alcohol-based hand sanitizer (with at least 60% alcohol) can be an alternative if soap and water are not available.
