Is the most important step in washing your hands scrubbing with friction?

The assertion that scrubbing with friction is the most important step in washing your hands is accurate. When washing hands, using friction to scrub helps to effectively remove dirt, bacteria, and viruses from the surface of the skin. This mechanical action dislodges pathogens that may be present, ensuring that they are washed away with soap and water.

Friction enhances the effectiveness of soap by creating a lather that helps to lift and trap these contaminants, making it easier to rinse them away. The Centers for Disease Control and Prevention (CDC) emphasizes that handwashing should include vigorous scrubbing for at least 20 seconds to maximize cleanliness.

Thus, the practice of scrubbing with friction is critical in the handwashing process, significantly contributing to the prevention of infection and the spread of illnesses.
