What is a key technique for effective handwashing?

Lathering with soap for at least 20 seconds and rinsing with clean water is essential to effective handwashing because it ensures that dirt, bacteria, and viruses are thoroughly removed from the hands. The mechanical action of rubbing hands together while lathering creates friction that helps to dislodge pathogens from the skin. The CDC recommends 20 seconds as a guideline based on studies that show this duration is sufficient to reduce microbial counts effectively. Additionally, rinsing with clean water helps to wash away the loosened germs and soap, which is crucial for maintaining hand hygiene.

While using antibacterial soap, wiping hands with a towel, and using hand sanitizer have their roles in hand hygiene, they do not replace the importance of thorough handwashing. Antibacterial soap can be effective, but regular soap and water are sufficient if used correctly. Wiping hands with a towel does not ensure all pathogens are removed, and hand sanitizer is less effective when hands are visibly soiled. Therefore, the key technique of lathering with soap for at least 20 seconds and rinsing properly is foundational for effective handwashing.
