Which methods can be used to sanitize surfaces?

• A. Cold Water
• B. Hot Water or Approved Chemical Solutions
• C. Soap and Water Only
• D. Dry Heat

Answer: (B)

Sanitizing surfaces means lowering any remaining germs to safe levels so they won’t cause illness. The reliable ways to achieve this are moist heat with hot water at a high enough temperature for a required contact time, or using an approved chemical sanitizer at the correct concentration and dwell time. Hot water transfers heat to kill many pathogens, while chemical sanitizers chemically inactivate germs; both are proven, regulated means to reach sanitization when used as directed. Cold water by itself can’t sanitize because it doesn’t inactivate most pathogens to safe levels. Soap and water is excellent for cleaning and removing soils, but sanitization specifically requires either heat or a chemical sanitizer after cleaning. Dry heat can sanitize in some contexts, but for routine surface sanitizing in many settings, hot water or approved chemical solutions are the standard methods.
