What should be used to ensure correct cleaning technique with hands?

Using soap and water is the most effective method for ensuring proper hand cleaning techniques. This approach not only helps to physically remove dirt and debris from the skin's surface but also effectively targets and eliminates bacteria and viruses. The mechanical action of scrubbing with soap and water significantly enhances the removal of pathogens compared to other methods, such as using hand sanitizer alone.

While hot water, hand sanitizer, and air drying may have their roles in hand hygiene, they are not sufficient substitutes for the combination of soap and water. Hot water can sometimes be too harsh on the skin and may not be available in all environments, while air drying alone does not provide the cleansing action needed to eradicate germs. Hand sanitizers are useful in situations where soap and water are not available but are less effective than soap in the presence of certain kinds of soil and grime. Overall, using soap and water is the recommended standard for hand cleaning to ensure optimal hygiene.
