But you/ve got to be curious first.
I noticed some 'rust' on pieces left in the weather. And 30 years ago I worked in a metal shop that had ONE item passivated. And as a home brewer, I learned that SS kettles need some acid, and also that chlorine as a sanitizer wrecks that passive coating. So then I searched the net for passivating specs. Turns out there is a milSpec.
