Abstract
Abstract A germicidal solution effective for disinfection of solid surfaces to destroy or to inactivate bacteria, microorganisms, protozoa, molds and viruses and the like contaminating said surfaces which comprises a polyvinylpyrrolide-aqueous solution of elemental iodine, a water-soluble iodide, and potassium bromide, said solution containing a sufficiently high concentration of elemental iodine to effect said destruction or inactivation.
