Which statement best describes the proper sequence for cleaning and sanitizing surfaces?

• A. Sanitize, then clean, then dry
• B. Clean, then dry, then sanitize
• C. Clean, then sanitize, and allow to air dry
• D. Air dry first, then sanitize

Answer: (C)

Cleaning first is essential because removing soil and organic matter lets the sanitizer work effectively; dirt can shield microbes and reduce the sanitizer’s ability to kill them. After the surface is clean, applying the sanitizer reduces any remaining microorganisms to safe levels. Finally, allowing the surface to air dry helps the sanitizer stay on the surface for its required contact time and avoids recontamination from wiping or using a cloth. So the sequence that matches best is to clean, then sanitize, and then air dry. Wiping or drying before sanitizing can remove or dilute the sanitizer and reintroduce contaminants, and drying before sanitizing would leave soils on the surface for the sanitizer to contend with. Always follow the sanitizer’s label for exact contact time and drying instructions.
