COPPER GLOW is a highly effective method for removing tarnish, oxides and corrosion products from the surface of parts made of copper, brass, bronze and other copper based alloys. COPPER GLOW in addition to removing these surface discolouration�s and restoring the metal�s natural gleam, leaves the surface passivated so that re-tarnishing or corrosion is retarded and the bright finish remains for some considerable length of time.
