The present invention is drawn to disinfectant or sterilant compositions and associated methods of use. In one embodiment, an aqueous disinfectant or sterilant composition can comprise an aqueous vehicle, including water, from 0.001 wt % to 50 wt % of a peracid, and from 0.001 wt % to 25 wt % of a peroxide. Additionally, from 0.001 ppm to 50,000 ppm by weight of a transition metal based on the aqueous vehicle content can also be present. The disinfectant composition can be used in the manufacture of disinfectant wipes, disinfectant gels, and disinfectant fogs. In one embodiment, the composition can be substantially free of aldehydes. Alternatively or additionally, the transition metal can be in the form of a colloidal transition metal.
