Ultrasonic Jewelry Cleaners

What is an Ultrasonic Jewelry Cleaner?

An ultrasonic jewelry cleaner is a device that uses ultrasound waves and chemicals to clean jewelry. The device creates microscopic bubbles that cling to foreign particles such as dirt, oil, tarnish, and polishing compounds, removing them from delicate jewelry pieces.

The cleaner operates using a liquid, such as water or a suitable solvent, in which the jewelry is submerged.

The cleaner then emits high-frequency waves through the liquid, agitating it and creating microscopic bubbles that implode when they reach a certain size, effectively removing dirt and grime clinging to the jewelry.

How Does an Ultrasonic Jewelry Cleaner Work?

Ultrasonic cleaners consist of various parts, including a tank, temperature controllers, transducers, and various modes of operation. The transducers are responsible for emitting ultrasonic energy, with the tank vibrating so that this energy can be spread effectively.

The cleaning process is quick and efficient, taking only a few minutes to complete.

Once the cleaning process is complete, the jewelry is removed from the cleaner and rinsed with water before being dried with a soft cloth.

What are the Benefits of Ultrasonic Jewelry Cleaners?

Ultrasonic jewelry cleaners differ from traditional cleaning methods in the way they eliminate dirt and organisms. Traditional cleaning methods use brushes, cloths, and cleaning solutions to remove dirt and grime from jewelry.

On the other hand, ultrasonic cleaners use high-frequency sound waves to create bubbles that scrub the surface of the jewelry, removing dirt and grime that are difficult to reach with traditional cleaning methods.

Ultrasonic cleaners are also more effective in cleaning inaccessible areas of the jewelry, which can be hard to clean when using a manual cleaner or hand washing. They are also gentle on delicate jewelry pieces, ensuring that they are not damaged during the cleaning process.

However, ultrasonic cleaners are not suitable for all types of jewelry.

Soft, delicate, and porous gemstones such as lapis lazuli, turquoise, and onyx can chip or break due to the strong vibrations of the machine.

It is important to read the manufacturer’s instructions and guidelines before using an ultrasonic cleaner.

When Should You Use an Ultrasonic Jewelry Cleaner?

Ultrasonic jewelry cleaners are ideal for cleaning most types of jewelry, including gold, silver, platinum, and diamonds. They are also effective in cleaning metal watchbands, eyeglasses, and other metal items.

However, ultrasonic cleaners will not remove tarnish, which is a common issue when cleaning jewelry.

In such cases, traditional cleaning methods or other specialized cleaning solutions may be more effective.

Benefits of Ultrasonic Jewelry Cleaners

If you’re looking for an effective and efficient way to clean your jewelry, then look no further than ultrasonic jewelry cleaners. These devices use ultrasonic waves to create bubbles that clear away all dirt and grime from the tiny crevices and hidden channels of your jewelry.

Here are some benefits of using an ultrasonic jewelry cleaner:

Effective Cleaning

Ultrasonic jewelry cleaners use high-frequency sound waves transmitted through a liquid solution of water or solvent to scrub clean the surface of immersed jewelry. The high-frequency sound waves, typically 20 to 40 kHz, agitate the liquid solution and cause the cavitation of solution molecules, which creates tiny bubbles that implode and remove dirt and grime from the jewelry.

This process is highly effective in cleaning your jewelry.

Safe for Delicate Items

Ultrasonic cleaners are gentle and do not damage delicate items, making them ideal for cleaning jewelry. Unlike traditional cleaning methods, ultrasonic cleaners do not use harsh chemicals or abrasive materials that can scratch or damage your jewelry.

This means that you can clean your delicate items without worrying about damaging them.

Reaches Difficult Areas

The cleaning process of ultrasonic jewelry cleaners reaches parts of the jewelry that are extremely difficult to clean with traditional cleaning methods. The cavitation bubbles formed when high-frequency sound waves hit water or solution affect the contaminants on the surfaces of the jewelry, including those in cracks, recesses, and blind holes.

This means that even the smallest and most intricate parts of your jewelry can be cleaned thoroughly.

Quick and Easy

The cleaning process of ultrasonic jewelry cleaners is quick and easy, taking only a few minutes. All you need to do is immerse your jewelry in the cleaning solution and turn on the device. The ultrasonic waves will do the rest, leaving your jewelry clean and sparkling in no time.

Saves Time and Labor

Multiple items of jewelry can be cleaned at the same time using an ultrasonic jewelry cleaner, saving time and labor. This means that you can clean all of your jewelry at once, rather than having to clean each piece individually.

This is especially useful if you have a large collection of jewelry.

Can be Used on a Variety of Materials

Ultrasonic cleaners work on a wide variety of materials, such as ceramics, glass, metals, rubber, and certain plastics. This means that you can clean different types of jewelry without having to worry about damaging them.


Ultrasonic cleaners are not expensive and can save money in jewelry cleanings over time. By using an ultrasonic jewelry cleaner, you can avoid the cost of professional jewelry cleanings and clean your jewelry at home.

Types of Jewelry for Ultrasonic Cleaning

Jewelry Compatible with Ultrasonic Cleaners

  • Gold: Ultrasonic cleaners are safe for gold jewelry, including white gold, rose gold, and yellow gold. However, if the gold jewelry has a lot of scratches or dents, it is best to avoid using an ultrasonic cleaner as it can worsen the condition of the jewelry.
  • Silver: Silver jewelry can be cleaned in an ultrasonic cleaner, but it should not be left in the cleaner for too long as it can cause discoloration.
  • Platinum: Platinum jewelry is safe to clean in an ultrasonic cleaner.
  • Diamonds: Diamonds are compatible with ultrasonic cleaners, but diamonds that have significant inclusions are at risk of damage since the ultrasound vibrations can make these internal flaws worse.
  • Some Non-Organic Gemstones: Some non-organic gemstones, such as sapphires, rubies, and emeralds, can be cleaned in an ultrasonic cleaner. However, it is important to check with the jeweler or the guide supplied with the jewelry to confirm whether the gemstone is compatible with an ultrasonic cleaner.

Jewelry to Avoid Ultrasonic Cleaning

  • Gemstones that are porous, have inclusions, or are treated with heat or chemicals should not be cleaned with an ultrasonic cleaner. Some examples of these gemstones are opals, pearls, and amber.
  • Tungsten: Tungsten jewelry should be avoided in an ultrasonic cleaner as it is susceptible to damage.
  • Organic Gems: Organic gems like Amber, Jet, and pearls should not be cleaned in ultrasonic machines.

Risks and Drawbacks of Ultrasonic Cleaning

While ultrasonic cleaning is an effective way to clean some types of jewelry, there are risks and drawbacks to using an ultrasonic jewelry cleaner. The ultrasonic vibrations can affect internal flaws and crack the stone, and some ultrasonic cleaners heat the water up to 80°C, which can damage gemstones vulnerable to heat or temperature changes, like opal.

If used improperly, ultrasonic cleaners can damage jewelry.

It is important to consult the guide supplied with the jewelry or a specialist to confirm whether your piece of jewelry is compatible with an ultrasonic cleaning machine or not. Therefore, it is recommended to use water and mild soap to clean jewelry instead of ultrasonic cleaners.

If you decide to use an ultrasonic cleaner, it is important to use it properly and avoid putting fragile stones in it, submerging watch heads in it, and using any cleaners or solutions that are not designed and labeled for that purpose.

Using an Ultrasonic Jewelry Cleaner

Cleaning your jewelry regularly is essential to keep it looking its best. An ultrasonic jewelry cleaner is a great tool for deep cleaning your jewelry and removing dirt and grime. In this guide, we will discuss how to use an ultrasonic jewelry cleaner to clean your jewelry effectively.

How Long Should You Clean Your Jewelry?

The amount of time it takes to clean jewelry with an ultrasonic jewelry cleaner can vary depending on how dirty the jewelry is. The cleaning time can range from 1 to 20 minutes or more. It is recommended to refer to the instruction manual of the ultrasonic jewelry cleaner for directions on how long to clean the jewelry.

After the cleaning is done, switch off the cleaner and leave the jewelry in the basket for about 10 minutes to allow the grime and dirt to settle.

Maintenance of Jewelry with Ultrasonic Cleaners

Ultrasonic cleaners are a popular and effective way to clean jewelry. They use high-frequency sound waves to create tiny bubbles in a cleaning solution, which then implode and remove dirt and grime from the jewelry.

However, there are some important things to keep in mind when using ultrasonic cleaners.

Frequency Matters

The frequency of ultrasonic cleaners is measured in kilohertz (kHz), and it can range from 15 kHz to 400 kHz. For most jewelry cleaning needs, a frequency of 40 kHz is recommended. However, if the jewelry has sensitive materials or a complex shape, a higher frequency between 80-130 kHz is recommended.

It’s important to choose the right frequency for your jewelry to avoid damaging it during the cleaning process.

Precautions to Take

There are certain precautions that should be taken when using an ultrasonic jewelry cleaner. Here are some tips:

  • Do not use flammable liquids such as gasoline or alcohol in the cleaner, as they can vaporize or even cause a fire.
  • Do not put your hands inside the solution while the ultrasonic cleaner is running, as the vibrating motion heats the liquid and might harm your skin.
  • Do not put in softer gemstones such as opals, lapis lazuli, emeralds, turquoise, (along with others), organic jewelry such as pearls, coral pieces, or amber, or gemstones whose color has been enhanced through heat treatment, as they can be easily damaged by ultrasound.
  • Do not mess with the electronic controls, transformer, or transducers on the unit, or try to do your own repairs, as ultrasonic cleaners operate under high voltage, and if you don’t know what you’re doing, you can damage the equipment and yourself.
  • Care must be taken to empty the bath and clean the bottom of metal parts. The bath should rest between cleaning cycles.
  • Wipe or spray down parts that have heavy, greasy, or loose contamination before placing them in the ultrasonic cleaner if possible.
  • Read the manufacturer’s instructions for use and follow them correctly to get the most out of your ultrasonic cleaner.

How Often to Clean

In general, ultrasonic cleaning can be done every couple of weeks, depending on how quickly the jewelry gets dirty. However, it’s important to pay attention to the condition of your jewelry and clean it as needed.

If you notice that your jewelry is looking dull or dirty, it’s time to give it a good cleaning.

Final Thoughts

Ultrasonic cleaners are a great way to keep your jewelry looking its best. By choosing the right frequency, taking precautions, and cleaning your jewelry regularly, you can ensure that it stays in top condition for years to come.

Just remember to follow the manufacturer’s instructions and take care when handling your jewelry, and you’ll be able to enjoy its beauty for a long time.
