Which disinfectant is effective against Clostridioides difficile spores?

Disinfectants that kill Clostridioides difficile spores must be sporicidal and used exactly as labeled. C. difficile forms hardy spores that survive ordinary cleaners, so only products with a sporicidal claim (often a bleach-based option or an EPA-registered sporicidal disinfectant) can reliably inactivate those spores when the surface remains wet for the required contact time. The key is letting the product stay on the surface for the labeled duration so the spores are fully inactivated. Regular quaternary ammonium cleaners are not reliably sporicidal, so they may reduce some dirt or microbes but won’t consistently kill spores. Water and soap remove soil and some organisms but do not destroy spores. The idea that any surface cleaner will kill spores instantly isn’t accurate; sporicidal products must be used with the proper contact time to be effective.
