How should we wash our hands? Firstly, wet our hands with clean, running water, turn off the tap, and apply soap. Next, lather our hands by rubbing them together with the soap. Lather the backs of your hands, between your fingers, and under your nails. Scrub our hands for at least 20 seconds. Next, rinse our hands well under clean, running water. Lastly, dry our hands using a clean towel or air dry them.
