If a surface required cleaning was not cleaned properly before disinfection, what should you do?

• A. Immediately reapply a stronger disinfectant without cleaning.
• B. Re-clean the surface to remove soil, then reapply disinfectant with proper contact time.
• C. Skip disinfection altogether.
• D. Wipe with water only and dry.

Answer: (B)

Cleaning must come before disinfection because soil and organic matter can shield microorganisms and prevent the disinfectant from working effectively. If you find that cleaning wasn’t done properly, re-clean the surface to remove soil and debris, then reapply the disinfectant and allow the proper contact time as stated on the product label. Simply increasing strength or trying to disinfect a dirty surface doesn’t reliably kill pathogens and can be unsafe or ineffective. Wiping with water only won’t disinfect, and skipping disinfection isn’t appropriate for routine salon sanitation. Re-cleaning first ensures the disinfectant can contact and inactivate microbes properly.
