Do-It-Yourself Jewelry Cleaner
You will need an old, gentle toothbrush (or a new toothbrush with soft bristles), and a solution of water and mild, liquid dish detergent (such as Dawn or Joy), mixed in equal proportions. Dip (or soak) your jewelry in the solution. Block the sink’s drain, and gently scrub the item, especially around the gemstones. Rinse the piece and either set it aside to dry, or pat it dry. Under no circumstances should you ever clean pearls, coral, emeralds, tanzanite, or other ‘soft’ gemstones with this method!
If your jewelry just needs light cleaning to restore a little sparkle, it’s easily done! Simply soak your jewelry in soapy water, and scrub with a soft-bristled toothbrush. Rinse well and allow the jewelry to dry. If you do this type of cleaning on a regular basis, more strenuous cleanings will not be as necessary. Do not use this technique on costume jewelry.
