Using soap and water while scrubbing for at least 20 seconds is the most effective method for handwashing to prevent the spread of infection. This technique allows for the removal of dirt, germs, and microorganisms from the skin. The mechanical action of scrubbing, combined with soap, breaks down oils and debris to ensure that pathogens are effectively rinsed away.

Hand hygiene is a critical component of infection control, particularly in healthcare settings. Proper handwashing helps to significantly reduce the risk of spreading infections, including those caused by resistant bacteria and viruses. While other methods, such as using antimicrobial wipes or hand sanitizer, may help in certain situations, they are not as effective as soap and water in completely eliminating all types of pathogens, especially when hands are visibly dirty or greasy. Rinsing hands under running water without soap does not remove germs effectively, making it an inadequate preventive measure.
