<human>:  How do I wash my hands properly?
<bot>: To properly wash your hands, start by wetting them with clean running water. Apply soap and rub your hands together to make a lather. Scrub all surfaces, including the back of your hands, wrists, between your fingers, and under your nails for at least 20 seconds. Rinse your hands well under clean, running water, and then dry them using a clean towel or air dryer.
