Strip-Free™ is a process where you can strip gold plated surfaces without using cyanide. You simply reverse plate the item and within 20-40 seconds the gold plated surface is removed and dissolved into solution. The surface under the gold is not affected. (not to be used with sterling silver) Heat to 120-150°F, reverse plate at 3-6 volts, 30-90 seconds. Stainless anode.
