The present invention is drawn to methods and compositions for use in partially or fully decontaminating surfaces which have been contaminated with chemical or biological warfare agents. The invention includes contacting the contaminated surface with a composition capable of ameliorating the negative effects caused by the warfare agent. In one embodiment, the composition includes an aqueous vehicle of water and from 0.001 wt % to 40.0 wt % of a peroxygen. Additionally, the composition can include from 0.001 ppm to 50,000 ppm by weight of a transition metal based on the aqueous vehicle content. Optionally, an alcohol can be included in the composition. In one embodiment, the transition metal can be in the form of a colloidal transition metal, such as colloidal silver.

What is claimed is: 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
What is claimed is: 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. 2. A method as in claim 1, wherein the surface being decontaminated is human skin, mucosal tissue, hair, or tissue within the alimentary canal. 3. A method as in claim 1, wherein the surface being decontaminated is a metal, fabric, plastic, composite, glass, wood, or terra firma. 4. A method as in claim 1, wherein said contacting of the contaminated surface can occur by spraying, wiping, pouring, or submersing. 5. A method as in claim 1, wherein the chemical or biological warfare agent is a chemical agent. 6. A method as in claim 5, wherein the chemical agent is selected from the group consisting of Tabun, Sarin, Soman, Cyclohexyl methylphosphonofluoridate, VX, Mustard agent (gas), hydrogen cyanide, arsines, phencyclidine, ricin, abrin, agent 15, or combination thereof. 7. A method as in claim 1, wherein the chemical or biological warfare agent is a biological agent. 8. A method as in claim 7, wherein the biological agent is selected from the group consisting of anthrax, Ebola, Bubonic Plague, Cholera, Tularemia, Brucellosis, Q fever, Machupo, Coccidioides mycosis, Glanders, Melioidosis, Shigella, Rocky Mountain Spotted Fever, Typhus, Psittacosis, Yellow Fever, Japanese B Encephalitis, Rift Valley Fever, Smallpox, or combination thereof. 9. A method as in claim 1, wherein the composition is substantially free of aldehydes. 10. A method as in claim 1, wherein the composition is substantially free of chlorine and bromine-containing components. 11. A method as in claim 1, wherein the composition is substantially free of iodophore-containing components. 12. A method as in claim 1, wherein the composition is substantially free of phenolic-containing components. 13. A method as in claim 1, wherein the composition further comprises an alcohol. 14. A method as in claim 13, wherein the alcohol is present in the composition at from 0.05 wt % to 40 wt %. 15. A method as in claim 13, wherein the alcohol is present in the composition at from 0.05 wt % to 20 wt %. 16. A method as in claim 13, wherein the alcohol is present in the composition at from 0.1 wt % to 10 wt %. 17. A method as in claim 13, wherein the alcohol is a C1-C24 alcohol. 18. A method as in claim 17, wherein C1-C24 alcohol is selected from the group consisting of methanol, ethanol, propanol, butanol, pentanol, or mixtures thereof. 19. A method as in claim 17, wherein the C1-C24 alcohol is a polyhydric alcohol. 20. A method as in claim 19, wherein the polyhydric alcohol is glycerol. 21. A method as in claim 19, wherein the polyhydric alcohol includes two alcohol groups. 22. A method as in claim 19, wherein the polyhydric alcohol includes three alcohol groups. 23.
