Which of the following is a proper way to wash hands?

Using soap and water for at least 20 seconds is the proper way to wash hands because it effectively removes dirt, grease, and pathogens from the skin. The act of scrubbing with soap plays a critical role in dislodging harmful microorganisms that may be present. The recommended duration of at least 20 seconds allows sufficient time for the soap to break down any bacteria and viruses effectively.

This method is especially important in food safety, where the potential for cross-contamination is high. Handwashing with soap and water is more effective than using water alone, hand sanitizer alone, or rinsing without soap, all of which may not adequately eliminate pathogens. Hand sanitizer may be a suitable alternative when soap and water are not available, but it should not be relied upon as the primary method since it may not remove all types of germs and doesn’t effectively clean away dirt and grime.
