Always avoid contact with chemicals‚ such as hair spray, perfume‚ lotions‚ household cleansers, pool and sea water, and so on. You can help avoid these things by putting your jewelry on last when getting ready to go out.
Use a Jewelry cleaner or Windex to deep clean your jewelry and a soft, clean cloth to wipe your jewelry pieces after wearing them to remove natural body oils, sweat or residue. If your jewelry comes into contact with water, it is recommended that you dry it with a soft cloth or tissue, as moisture can damage surfaces and cause them to rust.
Gold and silver plated jewelry will also eventually tarnish or discolor if left out in the open air. To prevent this from happening, store your pieces in a cool, dry place, such as a jewelry box or case with the lid closed.
