The safe, easy way to clean fine jewelry at home in your dishwasher! Invented by a jeweler with 40 years of experience, this cleaner will clean most of your fine jewelry with professional results. No special chemicals to buy, just use the dishwasher detergent that you always use. It's safe for gold, sterling silver or platinum mountings containing: rubies, diamonds, sapphires, moissanite, synthetic birthstones, or cubic zirconia. Simply place a ring, pendant (without the chain) or pair of earrings in each egg and twist to secure the lid. Place chains or any jewelry containing small stones in the soaker tank. Put the eggs and the soaker tank in the outer basket and secure the top of the basket by firmly squeezing the outer locks. Set the basket on the top rack of the dishwasher and run with a full load. Be sure to follow all the instructions when using this cleaner. Made in the USA.
