If the second wet cloth fails for the CV, how long must the certified renovator wait before wiping the surfaces with an electrostatically charged white disposable cleaning cloth?

• A. 30 minutes
• B. 4 hours
• C. 2 hours
• D. 1 hour

Answer: (D)

During cleanup verification after disturbing lead-based paint, you wipe surfaces with wet cloths to check that dust levels meet the standard. If the second wet cloth wipe fails to meet the criterion, the protocol requires waiting one hour before doing the final cleaning pass with an electrostatically charged white disposable cleaning cloth. That waiting period helps reduce re-entrainment and gives any remaining dust a moment to settle, so the subsequent electrostatic wipe can more effectively remove what’s left. After the hour, you perform the final wipe with the electrostatic cloth, which is designed to attract and hold remaining lead dust, providing a more thorough cleanup before you recheck the area.
