Abstract: Methods and compositions for inhibiting corrosion of a metal product are provided. The metal product can be contacted with water that includes at least one carbonate and/or bicarbonate salt, or otherwise has components that increase the alkalinity of the water. In addition, or as an alternative, the water can include a stannous corrosion inhibitor. The water can be evaporated off of a surface of the metal product to provide a residual of the salt on the surface and/or a protective stannous film on the surface.
