These polishing cloths are pretty much the same ones I used when I worked at a jewelry counter in a department store. They are both a cleaning cloth in one side and a polishing cloth on the other. I would definitely recommend they be used to maintain jewelry that is new, or that has been cleaned with the appropriate jewelry cleaner - this way, the cloths will last longer. Its important to use the right cloth for the piece of jewelry you want to clean. For maintenance of silver, they are fantastic and get the job done quickly.
