Caring For Cubic Zirconia
Use a cotton or flannel cloth to wipe your jewelry clean. A special jewelry polishing cloth would be perfect.
Using straight, back and forth strokes, polish your jewelry and remove any surface dirt and dust. Do not rub in a circular motion as that can scratch the surface of your jewelry. Then use a cleaning solution to remove grime and dirt.
Just like a diamond, a cubic zirconia can be cleaned with warm water and mild soap. Use a soft, cosmetic applicator to reach crevices. However, if you wish, you can use a trusted jewelry cleaner to remove any dirt and dust from your CZ.
Steam your CZ jewelry. Using a teakettle or any other method that produces steam, hold your jewelry directly over the steam stream to loosen dirt. You should wear gloves and use tongs or needle-nose pliers to avoid burns. Once steamed, use your polishing cloth to dry your jewelry.
Clean your jewelry with an ultrasonic cleaner. These units are inexpensive and nice to have if you own a lot of CZ jewelry.
Store your jewelry in an airtight, sealable plastic bag. If this is not possible, store your jewelry in a lined jewelry box, away from the outside air.
