The same care should be taken with Swarovski crystal as it should for gemstones - wipe them with a soft clean cloth
and store separately in tissue paper or a soft cloth.
The crystals will chip if they are stored with other pieces of jewellery.
Swarovski can be washed by hand using a very mild soapy detergent in lukewarm water and dried using a
lint free cloth.
No harsh abrasives should ever be used and I would avoid putting your Swarovski in an ultrasonic cleaner.
