Gently brush the stones with an old, very soft toothbrush dipped in a
solution of mild soap and warm water. If there is a layer of dust, you can
easily remove it with a dry, clean, and anti-static cloth. In this instance, a
microfiber or lint free cotton cloth works well. Rhinestones are glued onto the
fabric, so don't get them too wet. Place face down on a terry-cloth towel to
dry.
