According to the jewelry craftsman in this video, jewelry repair is not a high-tech affair. It’s done with the same kind of buffing and polishing that has been used for many years. He demonstrates the cleaning following a resizing, using a couple different polishing compounds. Of course, after all the buffing and polishing—using buffing and polishing compounds that stick around on the jewelry—his cleaning tool of choice? An ultrasonic jewelry cleaner. The ultrasonic cleaner takes away at least a little of the manual labor. After the ultrasonic cleaning, a quick jet of steam and the jewelry sparkles.
