Chemical sanitization is a process that uses chemical agents to reduce the number of microorganisms on surfaces to safe levels. Common sanitizers include chlorine, quaternary ammonium compounds, and hydrogen peroxide. These chemicals are often used in food service, healthcare, and household cleaning to ensure that surfaces are hygienic and safe for use. The effectiveness of chemical sanitization depends on factors such as concentration, contact time, and temperature. Proper application is crucial, as insufficient use may not eliminate harmful pathogens, while excessive use can lead to chemical residues. Following manufacturer guidelines ensures optimal results in maintaining cleanliness and safety.
