Wet storage stain (also called white rust) is most commonly found
on tightly stacked or bundled items with zinc on the surface, such as
galvanized sheets, bars, guardrail, industrial pipes and plates. In treating wet storage stain the best
cure is prevention. Preventing wet storage stain includes two steps:
1. Providing
adequate air flow to newly galvanized surfaces
2. Removing
standing water from newly galvanized surfaces.
If wet storage
stain does form, the affected objects should be removed from the high moisture
environment and arranged so the zinc coating can dry rapidly. Once dry, most
stains can be easily removed by brushing with a stiff nylon brush. If using a
nylon brush does not remove wet storage stain, a cleaning product should be
used. It is one of the metals chronic diseases whose treatment and prevention
is very much necessary because it has been used in every type of construction throughout
the world.
The goal of
this study was to find commercially available cleaning products and/or
techniques to remove wet storage stain from galvanized steel without dulling
the galvanized surface.
