Hand wash is a liquid soap designed for cleaning hands. It typically contains surfactants that help remove dirt, bacteria, and viruses from the skin. Hand wash is often available in various forms, including foams, gels, and liquids, and may come in scented or unscented options. Regular hand washing is an essential practice for maintaining hygiene and preventing the spread of illnesses. To use hand wash effectively, apply a small amount to wet hands and rub them together for at least 20 seconds, ensuring that all areas, including between fingers and under nails, are cleaned. Rinsing thoroughly with water removes the soap along with any contaminants. Proper hand washing is especially important during times of illness or after being in public spaces.
