The compositions provide good germicidal efficacy against both Gram positive and Gram negative bacteria on hard surfaces and the like. Processes for the sanitization of hard surfaces wherein the presence of Gram positive and/or Gram negative bacteria is suspected are also disclosed. ## Claims ### Claim 1 An aqueous hard surface cleaning and/or sanitizing composition which comprises: an anionic surfactant; an alkali metal hydroxide; soap; solvent selected from alcohol, glycol ether, or mixture thereof; and water. ### Claim 2 (depends on 1) The composition according to claim 1 wherein the surfactant is present in an amount of from about 0.01 to about 20 wt. %. ### Claim 3 (depends on 1) The composition according to claim 1 wherein the alkali metal hydroxide is present in an amount of from about 0.01 to about 2 wt. %. ### Claim 4 (depends on 1) The composition according to claim 1 wherein the soap is present in an amount of from about 0 to about 20 wt. %. ### Claim 5 (depends on 1) The composition according to claim 1 wherein the solvent is present in an amount of from about 0.1 to about 10 wt. %. ### Claim 6 (depends on 1) The composition according to claim 1 whererin the solvent is an alcohol or glycol ether. ### Claim 7 (canceled) ### Claim 8 (depends on 1) The composition according to claim 1 wherein the solvent is a mixture of alcohol and glycol ether. ### Claim 9 An aqueous hard surface cleaning and/or sanitizing composition which comprises: 0.01-20 wt. % of an anionic surfactant; 0.01-2 wt. % of an alkali metal hydroxide; 0-20 wt % soap; 0.1-10 wt % of a solvent selected from alcohol, glycol ether, or mixture thereof; and water to 100 wt %. ### Claim 10 (depends on 9) The composition according to claim 9, further comprising 0.1-20 wt % soap. ### Claim 11 (depends on 10) The composition according to claim 10, wherein the solvent is an alcohol. ### Claim 12 (depends on 10) The composition according to claim 10 wherein the alcohol is benzyl alcohol. ### Claim 13 (depends on 10) The composition according to claim 10 wherein the solvent is a glycol ether. ### Claim 14 (depends on 10) The composition according to claim 10 wherein the glycol ether is propylene glycol phenyl ether. ### Claim 15 (depends on 10) The composition according to claim 10 whererin the solvent is a mixture of alcohol and glycol ether. ### Claim 16 (canceled) ### Claim 17 (canceled) ### Claim 18 (canceled) ### Claim 19 (depends on 1) A process for the sanitization of hard surfaces and articles wherein the presence of bacteria is suspected which comprises the process step of: contacting the surface with a disinfecting effective amount of a composition according to claim 1 for a sufficient time to sanitize said surface. ### Claim 20 (depends on 9) A process for the sanitization of surfaces and articles wherein the presence of bacteria is suspected which comprises the process step of: contacting the surface with a disinfecting effective amount of a composition according to claim 9 for a sufficient time to sanitize said surface. ### Claim 21 (depends on 1) A composition according to claim 1 characterized in that: the compositions exhibit germicidal efficacy against Gram positive bacteria on hard surfaces. ### Claim 22 (depends on 1) A composition according to claim 1 characterized in that: the compositions exhibit germicidal efficacy against Gram negative bacteria on hard surfaces. ### Claim 23 (depends on 1) The composition according to claim 1 characterized in that: the compositions provide at least a 2 log10 reduction of Salmonella choleraesuis using a Biomek assay at a 15 second contact time. ### Claim 24 (canceled) ### Claim 25 (depends on 1) A composition according to claim 1 characterized in that: the compositions exhibit blooming when diluted in water at a ratio of 1 part of the composition to 10 to 100 parts of water.
