Details About 4.5L Jewelry Ultrasonic Cleaner Without Drain Vavle

How to use an ultrasonic jewelry cleaner?

Using an ultrasonic jewelry cleaner is easy and time-saving. All you have to do is follow a few steps, which are the same for most cleaners on the market.

  • Most ultrasonic jewelry cleaners work with a cleaning solution that is used to fill the tank of the machine, as per manufacturer’s instructions. However, some models on the market work with tap water. This, of course, depends on the model so check the instructions of your particular model carefully prior to use.
  • Once the tank is filled, place the jewelry items into the cleaning solvent and turn the machine on. If you are putting in multiple items, just take care that the jewelry does not damage each other.
  • Ensure that the water is hot to get the most effective clean. Many people skip this step, using cold water instead, but this does not give as effective a clean as when using hot water. Some ultrasonic jewelry cleaner models have a built-in heater feature that keeps the water at the right temperature for the best clean. However, do NOT use boiling water as this can damage your jewelry.
  • As the cycle kicks into motion, you will notice the ultrasonic vibrations moving through the liquid, whipping up agitated bubbles. The heat and pressure this creates start to remove the dirt build-up. You will be able to adjust the heat and intensity of the cleaner as required.
  • After the cleaning cycle is complete, it is best to leave your jewelry items for several minutes in the water for the dirt to separate from the items.
  • Finally, take your items out, give them a rinse in clean water to remove the cleaning solution and then use a soft brush to remove any clinging dirt particles from the jewelry items. This does not need to take long, as the dirt is already loosened. Just ensure that you brush the difficult areas such as the claws and crevices of your items.
  • Give the items one final rinse. You can do this manually or in the ultrasonic cleaner. Just use clean water and once complete, dry the items using a soft cloth.

Types of jewelry that you should be careful in an ultrasonic jewelry cleaner

While ultrasonic jewelry cleaners are convenient and effective ways to get your jewelry to sparkle again, it does not work on all types of jewelry items. Remember that not all jewelry is created equal. Some are harder, tougher and more durable than others.

The following types of jewelry that should not be used in ultrasonic jewelry cleaners if you want to keep them from damage:

  • Soft, delicate and porous gemstones such as lapis lazuli, turquoise, and onyx. These can chip or break due to the strong vibrations of the machine.
  • Organic pieces such as pearls, amber, and coral are very soft and should not be exposed to the strong pressure and heat of ultrasonic jewelry cleaners.
  • Gemstones with inclusions and flaws are at great risk of breaking or chipping in ultrasonic jewelry cleaners. Certain gemstones such as emeralds are known for having many inclusions and should not be used in the machine. Also, take care of clarity-enhanced gemstones. These have often been enhanced with fracture-filling treatments that can crack easily when exposed to heat and pressure.
  • Gemstones that have had heat treatments to enhance color. The ultrasonic jewelry cleaner can adversely affect the color of the stone, decreasing the vividness of the color.
  • It’s true that diamonds are the hardest stones on the planet, but they are also very brittle and often contain inclusions. If you have a diamond that has a low clarity grade (meaning a higher number of inclusions), do not use an ultrasonic jewelry cleaner as this can cause internal damage in the diamond. If the diamond has been fracture-filled, again avoid ultrasonic cleaners as the stone can crack.
  • Most metals can be used in ultrasonic jewelry cleaners, such as gold, silver, and platinum. However, tungsten is an exception as it can easily be damaged and it is recommended not to use it with ultrasonics.
  • Costume jewelry should never be used in cleaners because they often contain imitation gemstones that can crack under pressure and heat. Also, some costume jewelry items are made with glue which can dissolve in the cleaner, ruining your jewelry in the process.
