Yes, the pendant can and should be cleaned every so often. The best way to do that is by using a soft polishing cloth. Avoid placing the pendant into water, but in the event your energy pendant does get wet for any reason, a soft paper towel is all you need to dry it off. To help keep the pendant and any other Life Harmony Energies jewelry looking its best, remove them from your body prior to swimming, taking a shower, or performing strenuous activity that might get perspiration or moisture on the surface of the material . Keep the pendant away from sunscreen, cosmetics, perfumes, and products that contain alcohol or any other harsh, stringent chemicals. All of these things can wear away the finish of the pendant and damage the appearance as a result.
