Which is the first step in the cleaning process?

• A. Rinse
• B. Wash
• C. Sanitize
• D. Air-dry

Answer: (B)

Washing first removes soil and debris using soap or detergent and some mechanical action. This step is essential because it physically dislodges grime and reduces the amount of material that microbes can cling to. If you start with rinsing or sanitizing without cleaning, dirt can shield microorganisms and interfere with the effectiveness of sanitizers. The typical sequence—wash, rinse, sanitize, then air-dry—works because washing loosens and removes soils, rinsing clears away soap and loosened particles, sanitizing attacks remaining microbes, and air-drying prevents recontamination.
