How do you clean 950 platinum jewelry?
950 platinum is 95% pure platinum which is the standard for platinum jewelry. 950 platinum can be cleaned like any other piece of fine jewelry. A jewelry solution could be purchased, but I can tell you what many jewelry stores use in their ultrasonics. I know of many jewelers that mix half Mr. Clean and water with a small amount of ammonia for their jewelry cleaning solution in their ultrasonic. This works excellent for all types of jewelry. Allow the piece to soak for 15 seconds then rinse in water and dry. A polishing cloth can be used if the piece needs to have the high polish shine brought back.

Why is platinum used in jewelry?
Platinum has become a favorite precious metal among jewelry makers and jewelry shoppers everywhere - and for good reason! Not only is platinum beautiful, it's also very durable, even more so than silver or gold. For those looking for jewelry that requires little up-keep, platinum is the perfect option because it doesn't tarnish and it even gains more of a radiant sheen over time. For all these reasons and more, platinum has soared in popularity among jewelry consumers, leading to an increase in the manufacture of this precious metal in an effort to meet its growing demand.
