Which is NOT a recommended part of handwashing?

Using hot water only is not a recommended part of handwashing because the temperature of the water does not significantly affect the effectiveness of removing germs and dirt. Instead, it is more important to focus on the technique and duration of handwashing. Both cold and warm water are effective when combined with soap, which is what physically removes contaminants from the hands.

The other options are critical components of effective handwashing. Cleaning under the nails helps eliminate hidden bacteria and dirt often overlooked. Scrubbing both the palms and backs of the hands ensures a thorough clean, as both areas can harbor harmful pathogens. Rinsing with clear water is essential to wash away the soap along with any loosened dirt and germs. Proper handwashing techniques improve hygiene and reduce the spread of illnesses.
