If a sanitizer label requires a contact time of 60 seconds, what should you do?

• A. Rinse surfaces immediately after cleaning
• B. Wipe surfaces dry before 60 seconds
• C. Use a different sanitizer
• D. Ensure surfaces stay wet for the full 60 seconds

Answer: (D)

Keeping the sanitizer on the surface for the full contact time is essential. The label’s 60-second requirement is what lets the sanitizer work effectively against microbes. If you rinse off early, wipe it off before the time is up, or otherwise remove the solution before 60 seconds, you’ve shortened the exposure and weakened sanitization. If the surface starts to dry, reapply the sanitizer to maintain a wet film for the entire 60 seconds. Once the time has elapsed, you can let it air dry or wipe per the label’s directions.
