This soft paste metal polish cleans, restores, and leaves a protective film on metal surfaces, including chrome, silver, aluminum, brass, copper, and stainless steel. It removes surface tarnish, oxidation, and corrosion while bringing raw and plated metals to a high-luster shine. The protective coating helps prevent future tarnish accumulation and atmospheric deterioration. It is suited for polishing metal radio chassis, tube shields, brass escutcheon plates, tone arms, and mechanical hardware on vintage audio equipment.
