Can hand sanitizer be used as a substitute for handwashing?

Hand sanitizer is not a substitute for handwashing in situations where hands are visibly dirty or greasy, or when there are specific health and safety guidelines that dictate the use of soap and water. Washing hands with soap and water is more effective at removing certain types of germs, dirt, and contaminants, especially when food is being prepared or consumed. The mechanical action of scrubbing hands while washing plays a crucial role in dislodging and removing dirt and potentially harmful pathogens.

While alcohol-based hand sanitizers can effectively reduce the number of germs on hands in the absence of soap and water, they may not eliminate all types of germs and aren't effective when physical debris is present on the skin. Therefore, emphasizing proper handwashing techniques, particularly in critical situations such as food handling, remains essential for maintaining hygiene and preventing the spread of illness.
