1. A method of preparing an aqueous antimicrobial disinfectant formulation, the method comprising:
deoxygenating water;
adding ethylenediaminetetraacetic acid (EDTA) salt as a chelating agent to the water to form an electrolytic medium that is about 2-10% weight neutral salt in the water;
adding pH adjusters to the medium to obtain an electrolytic solution of pH in the range of 7 to 9;
applying a potential difference across an anode and a cathode in the electrolytic solution, wherein the anode includes at least one of silver, zinc, and copper and the cathode includes an inert conductive material;
gas sparging pressurized inert gas into the electrolytic solution;
filtering the electrolytic solution with a filtration assembly; and
mixing an excipient into the electrolytic solution at room temperature.
