How do I get my pieces clean after people handle it at a show, and get fingerprints off, too?
A lint-free cloth is a great way to remove fingerprints during, and after, the show. You can also clean some finished jewelry with a mild soap and dry with a soft, lint-free cloth. You should avoid scrubbing motions, especially with soft stones, as that can scratch the surface of the bead or cabochon.
You can also experiment with a variety of cleaning and polishing cloths to determine which works best for your pieces.
