Based on technology used by European silversmiths, P21SPolishing Soap is a firm, smooth, clay-based polish that getsapplied with it's own sponge. Wet the sponge, draw it across thepolishing soap, squeeze sponge to create a lather and beginpolishing! Rinse with water or allow to to dry to haze and buffoff. Dulling, rust and corrosion disappear in seconds, many timesfaster and easier than the "2 finger" polishing that soft pasteshave offered for years. This 10.6 oz jar outlasts several tubes ofpolish.
