Before applying EPA disinfectants to surfaces, the surface should be what?

• A. Precleaned
• B. Rinsed
• C. Dampened
• D. Dry

Answer: (A)

Precleaning is essential because EPA disinfectants work best on surfaces free of visible soil and organic matter. Dirt, oils, and hair products can shield germs and can even interfere with the disinfectant’s chemistry, making it less effective. In a salon, you wipe away debris with soap or a cleaning solution first, then apply the EPA-registered disinfectant and follow the label for contact time. That sequence—clean first, then disinfect—ensures the disinfectant can actually kill germs. Rinsing before disinfection, dampening the surface, or disinfecting a dry surface do not guarantee effective disinfection, which is why precleaned is the best choice when done properly and per product instructions.
