Does antibacterial soap for dishes kill semen on surfaces like the couch or the edge of a door ?

Only live one hour: Outside the body and in the absence of nutritive liquid, sperm live only about an hour. I am not sure that antibacterial soap would shorten this life span.

Yes: The sperm won't live long at all without semen or the body. I imagine that on a hard surface or cloth, they would live minutes, if that So cleaning with detergent certainly will kill sperm and clean up the stains. Not to worry
