For sterling silver we recommend using Connoisseurs Dazzle Drops Silver Jewelry Cleaner. To use the Dazzle Drops, simply wet the cleansing brush, place a small amount of Silver Cleansing Formula onto the jewelry, brush and then rinse the silver thoroughly in warm water and carefully dry. This will remove any discoloration and tarnish. For our patinated sterling silver and 14k gold pieces we ask special consideration to avoid the use of cleaners as they will remove the charcoal finish. For these pieces a damp, non- abrasive, chemical free cloth is all you need. Gold requires a little less maintenance and can easily be cleaned with warm water and a couple drops of dish cleaner such as Dawn. For touch up cleaning we recommend a Connoisseurs polishing cloth which can be purchased for either gold or silver. Chlorine and bleach often found in household cleaners, swimming pools and hot tubs should be avoided as they are harmful to precious metals, gemstones and will accelerate tarnishing.
