I have been using a Blitz cloth for cleaning jewelry since I was a young girl. My dad always had them and they shine up all my jewelry, both costume and fine jewelry. I think he used them to shine up cuff links and belt buckles. I wasn't sure if these were still sold but I would highly recommend them. They aren't as messy as liquid or paste products and they shine things up beautifully. I would not ever be without one as long as they keep making them. They last a very long time, also.
