Cleaning Tips: Use a soft cloth for regular cleaning.  For deep cleaning, use mild soap-water solution.  Don't use harsh chemicals at all.  Dry thoroughly to prevent moisture damage.  Storage Tips: Store in a cool dry place to prevent tarnishing.  Use individual pouches or cloth-lined jewellery pouches to keep them.  Avoid scratches and ensure that two jewellery pieces don't rub each other.  Use silica gel packets for controlling moisture.
