How to Care for Zinc

Zinc is used to coat other, rust-prone metals in a process known as galvanizing. Zinc protects the metal underneath from chemical corrosion and rust due to environmental exposure. Clean galvanized metal with hot, soapy water, or use a metal cleaner or all-purpose cleaning solution.

Newly galvanized metal is susceptible to staining if stored in unventilated areas or in wet cardboard boxes. This staining, known as wet storage stain, is easy to remove using a nylon brush or all-purpose cleaner. Zinc is rust resistant, but the metal underneath may show through and rust over time. If you see rust, remove it by lightly rubbing with sandpaper or a stiff brush.

Zinc requires very little maintenance. If you prefer a shiny appearance, then avoid abrasive cleansers, which can dull the surface. A twice-yearly application of paste wax will protect the finish on galvanized metals.

Smooth out small scratches in zinc-coated metals with fine-grit sandpaper. Wash well, then polish with metal polish or apply paste wax. If galvanized metal becomes so deeply scratched that the metal below shows through, it may require professional attention.
