• wherein an amount of the dimethylethanolamine is about 0.05% or above, to a maximum at about 40%, by weight, based on the total weight of the dimethylethanolamine and the water,
• whereby the treatment leaves the surface with about 0-3 ppm of chlorides, about 0-3 ppm of nitrates, and about 0-10 ppm of sulfates without leaving a film on the surface.
