To keep your SE bronze looking new and polished, simply pick up a silver polishing clothing. First clean the bronze piece with a bit of soap and water to remove any hard dirt. Dry very well then rub and polish bronze until desired “shinniness” is achieved. All SE pieces are sealed with a heat treated clear coating to postpone tarnishing and keep it shinny, it is not recommended to wear your pieces in the water. All bronze used for SE Jewelry is Lead and Nickle FREE.
