Disclosed is a method of manufacturing a stainless steel component, the method including texturizing (400) a stainless steel substrate by bead blasting to provide a texturized stainless steel. The stainless steel substrate includes grade 316 austenitic stainless steel. The method also includes treating (402) the texturized stainless steel with a passivation solution to provide a passivated stainless steel. The method further includes treating (404) the passivated stainless steel with an oxidizing solution including sulfuric acid and hydrogen peroxide at a temperature of about 130 to about 200 degrees Fahrenheit for at least 50 minutes to provide an antimicrobial stainless steel surface that is free of a separate coating. The method includes obtaining (406) at least 99.9% E. coli reduction as measured by JIS Z 2801:2010 test on the antimicrobial stainless steel without a separate coating.
