1. A method of decontaminating a surface contaminated with a chemical or biological warfare agent, comprising contacting said surface with a composition, comprising:
a) an aqueous vehicle, including:
i) water, and
ii) from 0.001 wt % to 40 wt % of a peroxygen; and
b) from 0.001 ppm to 50,000 ppm by weight of a colloidal transition metal or alloy thereof based on the aqueous vehicle content, wherein the transition metal or alloy thereof is an elemental metal selected from the group consisting of ruthenium, rhodium, osmium, iridium, palladium, platinum, copper, gold, silver, alloys thereof, or mixtures thereof; and
wherein the composition is substantially free of quaternary ammonium-containing components.
