We don't recommend it on soft platings. Most older silverplate is okay, but we recommend that you try to polish the piece in an inconspicuous spot to test. DO NOT use Flitz, or any polish, on any plated item unless the manufacturer specifically recommends it. Flitz is not dangerous to use on any metal, but the actual polishing is what rubs the plating off. Chrome plating is different and quite thick. Flitz is safe on Chrome.
