Cleaning & SanitizingQuestion 141 of 319
After applying a chemical sanitizer to a clean food-contact surface, the worker should:
a.Apply a second coat right away to be extra safe
b.Allow the surface to remain wet for the contact time on the product label, then air dry
c.Wipe it off immediately with a dry towel
d.Rinse the surface with hot water to remove the chemical
Explanation
Chemical sanitizers need a minimum contact time (often 30 seconds to a few minutes, depending on the product label) to kill pathogens. The surface must stay wet for that time, then be allowed to air dry. Wiping or rinsing too soon removes the sanitizer before it can do its job.
