Is it better to clean your hands using plain soap and water?
The WHO recommends cleaning your hands by rubbing them with an alcohol-based formulation, like adrop formula, as the preferred means for routine hygienic hand antisepsis if hands are not visibly soiled. It is faster, more effective, and better tolerated by your hands than washing with soap and water. Check this WHO report. However, hand sanitizers are not as effective when hands are visibly dirty or greasy, in that case hand washing with water & soap would be a better solution.
