Soap and Water
Soap and water are an effective way to clean hands and remove germs, dirt, and oils. Soap contains molecules called surfactants that break down oils and dirt, including some bacteria and viruses, making them easier to wash away. Water helps rinse these contaminants off the skin. The combination of soap and water creates a physical and chemical process that effectively reduces the risk of illness transmission. Proper handwashing for at least 20 seconds ensures thorough cleaning, promoting hygiene and health.
