What is the correct procedure for disinfecting a brush?

• A. Remove hair, wash with soap and water, then immerse in disinfectant.
• B. Soak the brush in disinfectant without cleaning.
• C. Rinse with hot water only.
• D. Air dry the brush before cleaning.

Answer: (A)

Cleaning first is essential for effective disinfection. Removing hair and built-up residue creates clean surfaces so the disinfectant can reach and kill microorganisms rather than being blocked by dirt.

Begin by removing any hair, then wash the brush with soap and water, scrubbing to lift and flush away debris. Rinse well to remove soap and loosened material. After thorough cleaning, fully immerse the brush in an appropriate disinfectant for the contact time specified on the product label, making sure every part of the bristles and base is covered.

Rinse as directed after disinfection and let the brush air-dry completely before using or storing it. This sequence ensures the disinfectant can work effectively and that the brush dries clean and ready for use.

Soaking without cleaning leaves debris that can shield microbes and reduce disinfectant efficacy. Rinsing with hot water alone doesn’t kill microorganisms. Air-drying before cleaning delays disinfection and allows contaminants to persist.
