ABSTRACT:
Medical instruments, which may include brass, copper, aluminum, stainless steel, carbon steel, or plastic parts are sterilized or disinfected in an anti-microbial solution. The anti-microbial effect of a strong oxidizing agent, such as peracetic acid, is improved with a wetting agent. The solution further includes a triazole or other component for inhibiting the corrosion of copper and brass. Phosphates or other buffering agents adjust the oxidizing agent generally to a neutral pH for preventing the corrosion of steel. Molybdates or analogous compounds also buffer the pH and inhibit corrosion of aluminum by the oxidizing agent. The corrosion inhibiting is enhanced by the wetting agent. Optionally, a sequestering agent is provided for inhibiting hard water precipitation.
