What happens when galvanized steel gets wet?
Once the galvanized zinc coating is exposed to free flowing air, a thin layer of zinc oxides forms on the surface starting the natural weathering process. Then, when the piece comes in contact with moisture – rainfall, dew, humidity – the zinc oxide particles capture the water to form porous, gelatinous zinc hydroxide.
Is it safe to cook in galvanized steel?
Galvanized steel is a type of steel that has a protective coating applied to it. The coating is hazy and gives the steel an orange color. It does not react with food in any way, so it is perfectly safe for oven interiors.
