This polishing cloth is double-layered to assist with the cleaning and polishing of your sterling silver, 14K gold, 18K gold, bronze, copper, stainless steel, brass, palladium and platinum jewelry. Start by polishing jewelry with the interior layer of cloth. It is specially treated to polish your jewelry and enhance shine. Avoid over-polishing as it can remove details and potentially cause your jewelry to lose designed oxidation and patina on bronze. Then use the outside layer of cloth to wipe/buff the jewelry. Buff your jewelry using the outside layer to remove any remaining dirt or tarnish and give your jewelry a clean, shiny finish.
