Soak your jewelry for a few minutes in a bowl of warm water and a light detergent such as Dawn. This should loosen any caked-on debris. Remove it from the bowl, spray it with Windex and gently scrub it with a soft toothbrush. Make sure you get the sides and underneath, especially rings. Rinse the jewelry in a bowl of clean warm water and air dry on a paper towel. Make sure you never clean your jewelry over an open drain! Do not clean pearls, turquoise, malachite, Lapis or other stones in this family in this way. We recommend bringing most jewelry with these types of stones to us for professional cleaning. Janet Heller Fine Jewelry is not responsible for the maintenance of your jewelry, but we are happy to send it out to our craftsmen for professional cleaning, polishing and refurbishing should you choose. The fee for this service depends on the scope of this work.
