Based on technology used by European silversmiths, P21SPolishing Soap is a firm, smooth, clay-based polish that gets applied with it's own sponge. Wet the sponge, draw it across the polishing soap, squeeze sponge to create a lather and begin polishing! Rinse with water or allow to dry to haze and buff off. Dulling, rust and corrosion disappear in seconds, many times faster and easier than the "2 finger" polishing that soft pastes have offered for years. This 10.6 oz jar outlasts several tubes of polish.
