Similarly when it is especially damp or humid outside moisture can accumulate on stored galvanized steel waiting to be shipped and cause wet storage stain.

How do you clean galvanized sheet metal.

One of the ways in which galvanizing protects steel from corrosion is by the development of a thin barrier film of insoluble zinc corrosion products known as a patina on the outer surface of the galvanized steel through exposure to the atmosphere. Once you ve applied all methods go over the metal with two dry clean cloths to ensure the area is dry. Galvanized steel can often be found in sheet metal gutters and car doors and hoods.
