Disclosed are sprayable, pressurized inanimate surface and air liquid 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 copper source material which releases copper ions into the treatment composition, preferably a source of Cu(I) and/or Cu(II) ions at least one quaternary ammonium compound which provides a microbicidal benefit 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 a lower alkyl aliphatic monohydric alcohol in order to impart one or more advantageous technical or aesthetic benefits to the compositions, including one or more detersive surfactants wherein the composition has a pH of at least 5, wherein the treatment compositions 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 -96(2002) Standard Test Method for Efficacy of Antimicrobial Agents against Viruses in Suspension, or ASTM E1053 -11 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) against one or more challenge microorganisms.La présente invention concerne des compositions liquides pulvérisables sous pression de traitement des surfaces inertes et de lair ayant un effet microbicide sur les surfaces traitées, lesdites compositions contenant (ou dans certains modes de réalisation préférés pouvant être essentiellement constituées, ou pouvant être constituées de) : un matériau faisant office de source de cuivre qui libère des ions c
