Sanitizing is the process of reducing the number of germs and bacteria on surfaces to a safe level, as determined by public health standards. This is often done using chemical agents, such as disinfectants, or through physical methods like heat. Sanitizing is commonly applied in places like kitchens, hospitals, and schools to help prevent the spread of illnesses. It is important to note that sanitizing does not eliminate all microorganisms but lowers their numbers to minimize the risk of infection. Regular sanitizing practices are essential for maintaining hygiene in everyday environments, especially during outbreaks of diseases like COVID-19.
