You can take care of your gold-plated jewelry by doing the following:
Remove gold plated jewelry before swimming or exercising – Your sweat creates a chemical reaction to gold plated jewelry just like perfume, chlorine, and nail polish. Make sure to remove your jewelry before swimming or exercising so your jewelry will not become tarnished or blemished.
Put-on gold-plated jewelry after cosmetics have been absorbed – Wait a minute or two to put on your jewelry so you can be sure that your cream or liquid makeup has dried completely. Personal care products such as lotion or cosmetics can blemish your jewelry if they encounter it while wet.
Do not spray perfume on gold plated jewelry – If you use perfume or cologne on a regular basis, spray it on your body before you put on your gold-plated jewelry. Perfume and other sprays may contaminate the metal of the jewelry, making it look blemished or stained.
Keep gold plated jewelry in a plastic bag – When not using your gold-plated jewelry, put it in a plastic bag, remove the excess air by squeezing it, and seal it. The lack of oxygen in the bag will help keep the gold-plated jewelry bright and shiny. Put only one piece of jewelry per plastic bag to avoid scratching
