Industrial buildings - are often surfaced with metal, and the metal is often plagued by exposure to corrosive fumes as well as normal oxidation.
Removal of corrosion (whether caused by fumes or oxygen) involves application of de-oxidizing (or "reducing") solutions that kill the rust. The solutions are applied, left on for some time to work, neutralized, and washed off.
Immediately after drying, we paint the structures with an effective rust-inhibiting paint that is appropriate for the type of metal. It should be emphasized that the painting should occur as soon as possible --- rust never sleeps.
