Spore-forming organisms like C. difficile require a sporicidal disinfectant because their spores resist ordinary cleaners. Alcohol-based sanitizers kill many pathogens but not spores, so they won’t inactivate C. difficile on surfaces. Soap and water helps remove dirt and some spores through scrubbing, but it does not inactivate spores either, so it’s not sporicidal. A hydrogen peroxide spray that isn’t labeled sporicidal isn’t guaranteed to inactivate spores, so it shouldn’t be relied on for C. difficile. Sodium hypochlorite (bleach) at the recommended concentration and contact time is sporicidal and effectively inactivates C. difficile spores on surfaces when used correctly; for example, a 0.1% chlorine solution with adequate dwell time, while also being mindful of surface compatibility and safety.
