How to Clean Zinc Oxide Corrosion From Metal Surfaces eHow

Zinc oxide is a substance used to galvanize metal surfaces. It is highly resistant to corrosion and stays on the metal for long periods of time without the need for reappli ion. However, standing water on the zinc oxide can cause it to corrode, leaving a film of white powder. This corrosion stain is known as wet storage stain.
