How do you demonstrate the recommended method for hand washing?

To demonstrate the recommended method for hand washing, first wet your hands with clean, running water and apply soap. Rub your hands together to create a lather, ensuring you scrub all surfaces, including the back of your hands, between your fingers, and under your nails, for at least 20 seconds. Rinse your hands thoroughly under clean running water to remove all soap and dirt. Finally, dry your hands with a clean towel or air dry them.
