Does magnesium chloride corrode galvanized steel?
Magnesium chloride can aggressively attack many types of steel, including galvanized steel. Wet magnesium chloride is more aggressive than dry. Magnesium chloride should not be left on galvanized steel for prolonged periods of time. Washing the galvanized steel with a dilute mild detergent and then rinsing with fresh water is sufficient for removing magnesium chloride. Detergents meant for aluminum should not be used on galvanized steel.
