Ultrasonic cleaners have been popularly and efficiently used to clean intricate works of fine metal and gemstone jewelry. Not only that, but ultrasonic cleaning has also been declared safe for corundum stones, including sapphire and rubies by the Gemological Institute of America’s Essential Colored Stone Reference Guide. However, it should be kept in mind that the stones used for cleaning by ultrasonic cleaner are not weakened by fracture or have been cavity-filled to make a smooth stone surface.
Things You’ll Need
- Ultrasonic cleaner unit
- Liquid jewelry cleaner
- Mild dish liquid
- Warm water
- Clean towel
- Use commercial jewelry cleaning liquid, or warm water mixed with 2-5 drops of a mild liquid detergent to fill the ultrasonic cleaning unit up to the interior fill line.
- Place the jewelry or sapphires tones gently in the bottom of the ultrasonic unit or into agitation basket that is lowered inside the cleaner.
- Gently close the lid and tighten it. Turn the power on to initiate the agitation activity of the unit. The objects should be allowed to remain in the unit for recommended time given on the manual that comes with your ultrasonic unit.
- Remove all objects from the units once the cleaning cycle is complete. Remember to rinse the sapphire pieces and jewelry with warm water to remove the layer of cleaning solution that could dry out. Dry the pieces using a clean absorbent towel.
Tips & Warnings
In case of uncertainties about any fractures or filled cavities that your sapphires jewelry might have, it is advisable to refrain from using the ultrasonic cleaner until your jeweler can give you a go-ahead ensuring its safety.
