Follow these six steps every time:

1. Wet hands. Use clean, warm, running water.

2. Use soap and make it bubbly. Apply soap and lather your hands by rubbing them together with the soap. Lather the backs of your hands, between your fingers, and under your nails. Don’t forget your thumbs.

3. Scrub your hands for 20 seconds. Need a timer? Hum the “Happy Birthday” song from beginning to end twice.

4. Rinse your hands. Get all the soap and bubbles off under clean, running water.

5. Dry your hands. Use a clean towel or air dry them.

6. Turn off the water with a paper towel and throw it away.
