Maintenance of Metal Post Caps

Copper post caps and stainless steel post caps come with a thin, clear marine lacquer designed to protect them before and during installation. Once exposed to the elements, the sun’s ultraviolet rays, moisture, and pollution begin to break down this coating, exposing the metal underneath.

Copper

In its natural state, copper breaks down in the elements and develops a patina. In general, copper progresses from a natural salmon color to a series of russet browns and grays, and finally to a blue-green or gray-green patina.

To maintain the shiny look, apply a car wax immediately after purchasing the cap, and reapply every 3 to 6 months.
To remove an already tarnished finish, remove the old coating with mineral spirits and grade 0000 steel wool. Buff with grade 0000 steel wool for a satin finish; for a mirror-like finish, apply a car wax. Spray with a clear lacquer or polyurethane. Let dry and apply a car wax.
To encourage a natural patina, remove the lacquer with mineral spirits and grade 0000 steel wool.
