Disinfecting the Home with Bleach

By Dr. Laundry April 2, 2009

Q. I would like to know if your Clorox cleaner with bleach would kill C. Diff (Clostridium difficile)? My mother-in-law was diagnosed with C. Diff, and the family wants to know what to use to clean the house. I have read that only bleach will kill the germs. Could you please advise what product to use?

A. Definitely want to get the mother-in-law’s house cleaned up. Disinfecting bleach can be used. Preclean any surface, then make a disinfecting solution (3/4 cup Clorox® Regular-Bleach1 in a gallon of water). Wash or wipe this solution on all bleachable surfaces, then allow to stand for at least 5 minutes. Rinse and allow to air dry.
