Sterling silver flatware requires frequent care to maintain its luster and remove tarnish. Tarnishing occurs as the silver reacts chemically to the exposure of air, moisture, and dust, resulting in dark discoloration on the utensils. Because the flatware is not in daily use, the amount of tarnish and grime increases, and causes irreversible damage to the silver finish. Caring for sterling silver flatware involves proper cleaning, polishing, and storage; learning about these different techniques can help buyers properly care for their flatware and increase its value throughout time.
