How should contaminated surfaces be disinfected?

• A. Remove Soil, Apply An EPA-Registered Disinfectant, And Follow The Recommended Contact Time
• B. Wipe With Water Only
• C. Wipe With A Dry Cloth Only
• D. Disinfectant Is Not Necessary

Answer: (A)

Effective disinfection requires three steps: thoroughly cleaning the surface to remove soil and organic matter, applying an EPA-registered disinfectant appropriate for the surface and the pathogens of concern, and allowing the product to stay on the surface for the recommended contact time. Cleaning first matters because dirt and organic material can shield microbes and reduce disinfectant efficacy, so the disinfectant can’t work properly unless the surface is pre-cleaned. Using an EPA-registered product ensures proven effectiveness against the kinds of pathogens you’re targeting. The contact time is crucial: if the surface isn’t kept wet for long enough, the disinfectant may not kill the microbes present. Wiping with water only or with a dry cloth doesn’t reliably kill pathogens, and saying a disinfectant isn’t necessary would leave surfaces inadequately protected.
