What is the proper procedure for contaminated countertops, tools, and equipment?

• A. Disinfected without cleaning.
• B. Thoroughly cleaned and then disinfected for 10 minutes with an EPA registered disinfectant or bleach solution.
• C. Simply rinsed with water.
• D. Sanitized only.

Answer: (B)

Cleaning followed by disinfection is the proper approach for contaminated countertops, tools, and equipment. First, remove visible debris and organic matter by thoroughly cleaning with soap or detergent and water. This step is crucial because soil can shield microorganisms and prevent disinfectants from reaching them. After cleaning, apply an EPA-registered disinfectant (or a properly prepared bleach solution) and keep the surface wet for the labeled contact time, typically about 10 minutes in many salon settings. The labeled time ensures the disinfectant can effectively kill the pathogens present. Once the contact time is complete, allow the surface to air dry (or wipe as directed by the product label). This two-step process—cleaning to remove soil, then disinfection with the correct contact time—is necessary for proper infection control. Disinfecting alone, or sanitizing or rinsing without disinfection, won’t reliably eliminate contaminants on contaminated surfaces.
