Using an Ultrasonic
An ultrasonic cleaner is a device that uses ultrasound to remove the dirt from your jewellery. The items are placed in a tank filled with water and a non hazardous cleaning solution.
After the cleaner is turned on, the transducer produces ultrasonic vibrations through the liquid. These vibrations break down the dirt particles accumulated on the surface of your jewellery.
The benefits of ultrasonic cleaners is that they can clean the parts of your jewellery that are otherwise unreachable when using more conventional methods.
Remember to Heat It Up
One of the common mistakes people make when using an ultrasonic cleaner is to put cold water in the tank. For the cleaning solution to work best, the water should be warm to break down dirt particles better.
There are ultrasonic cleaners that have a built-in heater to ensure that the solution is heated up constantly.
Turn the device on and let it run for as long as needed until your jewellery is clean. After the cleaning is done, switch the cleaner off and leave your jewellery inside for another 5-10 minutes so that the dirt particles that were knocked off your pieces by the sound waves can fall to the bottom of the tank.
After you take your jewellery out, you can clean it briefly with a soft brush to make sure that any residual dirt is removed, especially from the mountings of your rings.
Rinse the items to wash off any remaining detergent and dry them with a soft cloth.
What You Should Not Put in an Ultrasonic Cleaner
Not all jewellery should be cleaned with an ultrasonic device.
Many gemstones can be easily damaged by ultrasound. Do not put in softer gemstones such as opals, lapis lazuli, emeralds, amber, turquoise, rutile Quarts etc.
Organic jewellery such as pearls, coral pieces or amber can also be damaged.
Also, do not put gemstones in that have had colour enhancement through heat treatment.
