What is proper hand washing procedure?

The proper handwashing procedure involves washing with soap for at least 20 seconds, rinsing, and then drying with a clean towel. This method is effective because the duration of at least 20 seconds is crucial for removing germs and contaminants from the hands. Handwashing is effective when it includes all these steps: applying soap, properly scrubbing all areas of the hands and under the nails, rinsing off the soap completely, and then drying the hands with a clean towel or air dryer.

By drying your hands, you not only ensure they are free of moisture—which can harbor bacteria—but also enhance the overall cleanliness since clean towels can further remove any residual pathogens. Skipping any part of this procedure, such as hand drying or not washing long enough, compromises the effectiveness of handwashing, leaving the hands still possibly contaminated.
