ANTI-CORROSION DETERGENT COMPOSITIONS AND USE OF SAME IN CLEANING DENTAL AND MEDICAL INSTRUMENTS

摘要

A method of cleaning metal medical and dental instruments to remove contaminants therefrom and inhibit corrosion, including(a) in a wash stage, washing the instruments in an aqueous solution containing a detergent composition including a low-residue corrosion inhibitor, then draining the liquid from the instruments, and (b) submitting the instruments to at least one stage of rinsing and draining using an aqueous rinse liquid, said aqueous rinse liquid including a selected concentration of said detergent which is effective to prevent corrosion in at least the final rinse stage, wherein the concentration of said detergent is lower in step (b) than in step (a).
