Germicidal compositions including a phthalaldehyde and methods of using su ch compositions for killing bacteria, disinfection, or sterilization, are disclosed. In one aspect, a germicidal composition may include a diluent, a germicidal compoun d, such as phthalaldehyde, and an amount of isophthalaldehyde to enhance the germicidal efficacy of the germicidal compound. In the case of phthalaldehyde, the composition m ay have a staining property that is less than a staining property of a composition consisting essentially of phthalaldehyde diluted to the same concentration. In another aspect, the composition may further include an amount of terephthalaldehyde to enhance t he germicidal efficacy of the phthalaldehyde. In yet another aspect, a germicid al composition may include a diluent, phthalaldehyde, and a material such as isophthalaldehyde, terephthalaldehyde, or a combination of isophthalaldehyde and terephthalaldehyde, in order to reduce a staining property of the phthalaldehyde.
