How long should routine hand wash with nonantimicrobial soap last?

The recommended duration for a routine hand wash with nonantimicrobial soap is 15 seconds. This time frame is established based on studies that show effective removal of viruses, bacteria, and other pathogens from the hands relies on thorough cleansing. During this 15 seconds, it's essential to use proper handwashing techniques, which include wetting the hands, applying soap, lathering thoroughly, and making sure to scrub all surfaces, including the backs of hands, between fingers, and under nails.

Handwashing for 15 seconds is generally considered sufficient to achieve an adequate level of cleanliness and reduce the likelihood of transmitting infections in a dental setting. Shorter durations, such as 5 or 10 seconds, may not provide enough time for the mechanical action needed to effectively remove dirt and microbes, thereby not meeting the standards of infection control practices in healthcare environments. The 20 seconds option, while potentially effective, is slightly longer than the recommended period for nonantimicrobial soap when a thorough technique is practiced.
