When cleaning cultured pearls at home, never expose pearls to harsh detergents such as dish soap or laundry soap, powdered cleansers, bleaches, ammonia-based cleaners or backing soda. Do not rub the outer surface of the pearl, known as the nacre, which gives the pearl its sheen. Do not use an ultrasonic cleaner or steam-clean the pearls. Never scrub a pearl’s surface with a scouring pad, toothbrush or other abrasive material.
To restore the sheen of pearls, wear cleaned and thoroughly dried pearls for a few hours, transferring body oils to the pearl’s surface. A tip is to wash pearls in salty water, mimicking their original oceanic environment. To refresh the appearance of pearl jewelry, have the pearls restrung once a year. To restore shine, use only chamois leather to gently buff the surface of the pearls.Learn more about Precious Metals & Gems
