I have quite a collection of CZ jewelry, and I want to make sure that I keep all of them as beautiful as possible at all times. I have been looking into how to clean them, and I found some very useful information on a website emporia.edu. While reading I found out they are very easy to take care of.  Cubic Zirconia's can be cleaned with jewelry cleaner. If you don't happen to have jewelry cleaner at home, you are in luck, CZ's can also be cleaned with soaps or detergents. If using detergents make sure to rinse thoroughly and dry completely to make sure a soap film is not left behind. A soap film will give a CZ a dull look, and I know I want mine to sparkle as much as possible. If your Cubic Zirconia is in a setting or set with another stone, be sure to read jewelry cleaner labels before using it. You want to keep your jewelry clean, but you don't want to ruin it in the process.
