I have often taken my jewelry to a local store when I would get my wedding rings cleaned and inspected, and they would clean 2-3 pieces for me at no charge. However, anything extra was quite expensive. So, I started looking for a way to clean my jewelry at home. When I saw this product, I thought it would be perfect. My greatest need is my necklaces as I often sweat a lot on my neck, so the jewelry gets tarnished. After receiving my cleaner machine, I eagerly put my favorite necklace in and started the process. The results were amazing!! I am SO pleased and so happy I purchased this product. Now, my jewelry looks almost new again. It's wonderful!
