*The best homemade jewelry cleaning solution is a mixture of a few drops of Dawn dish detergent in warm, not hot, water.
Let the piece sit in the solution for a few minutes, longer if it’s very dirty, then gently scrub with a new, baby-size, soft toothbrush. To rinse, place the item in a new container of warm water.
Make sure the water isn’t too hot or too cold, as some gemstones do not take well to drastic changes in temperature.
You can dry the piece off with a paper towel or a regular cloth, as long as you’re careful not to snag the prongs on the fibers.
*Or you can do it ,with a polishing cloth. Do not use polishing cloths or any chemicals on the surface of stones. Instead, wipe them with a soft cloth.
