A sporicidal composition has a moderately low pH and includes a glycosidase and the dissocia-tion product of at least one inorganic oxidizing agent. High effective solute concentrations can enhance the efficacy of the composition. The composition can be applied to a surface and allowed to absorb into an endospore, ultimately killing at least some of those bacteria in mature endospore form. Surfaces to be treated include inanimate (hard) surfaces via cleaning and medical devices such as endoscopes, typically via immersion.
