A few tips on how to keep your jewelry beautiful!
Here's a simple cleaning solution for sterling silver-
1 tablespoon baking soda
1 tablespoon dish detergent
1 cup water
1 piece aluminum foil
Heat water in the microwave until hot.
Cut a piece of aluminum foil that roughly covers the bottom of a small bowl (like a cereal bowl).
Pour hot water into bowl. Place salt, soda, and dish washing liquid into bowl. Place jewelry on top of foil and let it sit for 5 to 10 minutes. Rinse jewelry in cool water and dry jewelry completely with soft cloth. Discard solution after use and make a new batch next time.
According to wire-sculpture.com, "this works well for gold-filled, brass, german (nickel) silver, and sterling silver. I have even cleaned jewelry with freshwater pearls, shell cameos and mother of pearl with no problem.".
DO NOT use on copper.
If you store silver in plastic bags with an interlocking seal, it will be less prone to tarnish.
Try to protect any jewelry from scratches, sharp blows, harsh chemicals, extreme temperatures and sunlight.
Put your jewelry on after washing and applying any makeup/hair spray.
Never wear jewelry while swimming in a swimming pool. The chlorine can cause damage to various gemstones and gold.
Avoid storing your jewelry next to a heating vent, window sill or on a car dashboard.
