How could we disinfect a nail clipper/cutter if exposed to hepatitis c virus.

Scrub soap and water: The best approach is to have separate personal items that are not shared. Very important for toothbrush and razors- place somewhere so they can't be accidentally used by others. If nail clippers get shared, soak in soapy hot water. If there was obvious blood can also leave in bleach ( one part to ten parts water). Razors have crevices that are hard to sterilize.
