What is the first stage in the cleaning and sanitizing process?

• A. Wash the surface with hot water and detergent
• B. Remove loose dirt
• C. Rinse with clean water
• D. Use a sanitizer

Answer: (B)

Removing loose dirt is the first stage in cleaning and sanitizing because it clears away the largest soil particles before any wet cleaning steps. This pre-cleaning reduces the amount of soil that could smear or trap bacteria and allows the detergent and water to work more effectively on the remaining soil. After this initial step, you wash with hot water and detergent to lift soils, rinse with clean water to remove soap and loosened dirt, and finally apply a sanitizer to kill any lingering microorganisms on a clean surface. Skipping this initial dirt removal can let soil shield bacteria and make the subsequent cleaning and sanitizing less effective.
