Proper handwashing is essential for maintaining hygiene and preventing the spread of illness. The step of drying hands with a cloth towel may not be the most hygienic method as it can lead to cross-contamination, especially in environments where bacteria can easily thrive. Instead, using single-use paper towels or air dryers is often recommended because these methods minimize the risk of transferring bacteria back onto the hands after washing. In contrast, the other steps involved in handwashing—wetting hands with hot water, washing with soap for 10-15 seconds, and rinsing with warm water—are considered best practices. The focus during these steps is to effectively remove dirt, bacteria, and viruses from the skin. Hot water helps dissolve grease and aids in the removal of pathogens, while soap is crucial for breaking down oils and suspending them in water. Rinsing with warm water ensures that all soap and contaminants are fully washed away, contributing to effective hand hygiene.
