The preferred method for washing hands involves using soap and warm water for at least 20 seconds. This approach is effective because the action of scrubbing with soap not only helps to physically remove dirt and germs, but the soap itself plays a crucial role in breaking down the oils and residues on the skin where pathogens can reside. Warm water helps to activate the soap more effectively than cold water, promoting a better lather and, in turn, improving the overall cleanliness of the hands.

The recommendation of at least 20 seconds aligns with guidelines from health authorities, which suggest that this duration is necessary for thoroughly cleaning hands and reducing the presence of harmful microorganisms. This method is particularly important in food handling environments to prevent foodborne illnesses and ensure safety for both workers and consumers.
