Sanitizers are products designed to reduce or eliminate harmful germs and bacteria on surfaces or skin. They come in various forms, including gels, foams, and wipes, and are commonly used in places like homes, schools, and hospitals. The most popular type is hand sanitizer, which often contains alcohol to effectively kill germs when soap and water are not available. Using sanitizers is an important part of maintaining good hygiene, especially during cold and flu seasons or in the wake of outbreaks like COVID-19. Regular use can help prevent the spread of illnesses and keep both individuals and communities healthier. Always check the label to ensure proper usage and effectiveness.
