Disclosed are pressurized surface treatment compositions which impart a microbicidal benefit to treated surfaces which compositions comprise (or in certain preferred embodiments may consist essentially of, or may consist of): a zinc ion source material which releases zinc ions into the treatment composition, preferably a source of Zn++ ions, at least lower alkyl aliphatic monohydric alcohol which independently of other constituents present exhibits a microbicidal effect, a propellant; and, water. The compositions may further optionally include one or more further optional constituents such as a detersive surfactant and/or minor amounts of one or more constituents which impart one or more advantageous technical or aesthetic benefits to the compositions, including one or more detersive surfactants wherein the compositions have pH of at least 5. The compositions exhibit a microbicidal or germicidal or antimicrobial effect on treated inanimate surfaces and are characterized in exhibiting a microbicidal benefit when tested against one or more challenge microorganisms, preferably against poliovirus type 1 (Sabin) [“PV1”], according to one or more of the following standardized test protocols: ASTM E1052 Standard Test Method for Efficacy of Antimicrobial Agents against Viruses in Suspension, or ASTM E1053 Standard Test Method to Assess Virucidal Activity of Chemicals Intended for Disinfection of Inanimate, Nonporous Environmental Surfaces, or European Standard Surface Test, EN13697, or AOAC Germicidal Spray Products as Disinfectant Test Method, AOAC Index, 17th Ed. (2000).
