Answer 2

Clean your jewellery with a mild soap-and-water solution, allow water to bead up, and pat dry with a soft cloth. For more stubborn dirt, a jeweller is more appropriate. Store your silver in a cool, dry place, preferably in a tarnish preventative bag or wrapped in a soft piece of felt or cloth. Store pieces individually so that they don't knock together and scratch. Don't rub silver with anything other than a polishing cloth or fine piece of felt. Use of tissue paper or paper towels can cause scratches because of the fibers in these products. Don't expose to air and light when storing because it will cause silver to tarnish. And, don't wear sterling silver in chlorine water. GOLD Always separate your gold jewelry in a compartmentalized jewelry box or keep them individually wrapped. This protects against scratching. Remove all jewelry before showering or cleaning. Soap can cause a film to form on karat gold jewelry, making it appear dull and dingy. By preventing the formation of this film, you immediately reduce the occasions your pieces will need to be cleaned. You will also find a soft chamois cloth from any hardware store an effective and inexpensive way to keep your pieces lustrous and shining.
