Sure Shine is more than a metal polish! It is specially formulated as a one-step application that cleans, polishes, and protects most metals and fiberglass and Plexiglas products with an effective coating that is designed to last 3 to 6 months. It contains no harsh acids, caustics, or abrasives, so it is safe on most materials. Sure Shine performs wonders on brass, bronze, copper, stainless steel, aluminum, pewter, nickel, and sterling silver or silver plate. Sure Shine is also designed to clean and deoxidize fiberglass. It removes cloudiness from Plexiglas, clear vinyl, Eisenglass, or lexan. To use, apply a small amount of polish to the area that needs cleaning. Rub in a back and forth or circular motion with a soft cloth. Buff with a clean, soft cloth until all residue is gone, and the surface is bright and shiny.
