Hand sanitizers are alcohol-based products designed to reduce germs on the skin. They typically contain at least 60% alcohol, which helps kill bacteria and viruses. Hand sanitizers are convenient for use when soap and water are not available, making them popular in public places like hospitals, schools, and offices. These products come in various forms, including gels, foams, and wipes. While hand sanitizers are effective for many germs, they may not eliminate all types of pathogens, such as certain viruses or spores. Therefore, washing hands with soap and water is still recommended when possible, especially after using the restroom or before eating.
