What is an Ultrasonic Cleaner?
An ultrasonic cleaner is a device that uses high-frequency sound waves to clean delicate items, such as jewelry, electronics, and dental tools. It operates by creating ultrasonic vibrations (usually above 20 kHz) in a cleaning solution, which produces tiny bubbles that scrub the surfaces of items placed in the cleaner. This technology is based on the principle of cavitation, where tiny bubbles rapidly expand and collapse, generating a powerful cleaning action without damaging the material.
The Ultrasonic Cleaning Process
The process of ultrasonic cleaning begins with the ultrasonic cleaner generating high-frequency sound waves. These sound waves are transmitted through the cleaning liquid, which forms microscopic bubbles. When the bubbles collapse, they create high-energy scrubbing actions that break down dirt, grease, and other contaminants. This process happens on a molecular level, allowing the cleaner to reach areas that are difficult to clean manually, such as grooves or settings of gemstones.
This cavitation effect works exceptionally well for cleaning fine jewelry, as it removes contaminants without any harsh abrasion or the need for aggressive chemicals.
How Does an Ultrasonic Cleaner Work?
An ultrasonic cleaner typically consists of a tank, an ultrasonic transducer, and a cleaning solution. Here’s a step-by-step breakdown of how the device works:
Filling the Tank: You begin by filling the ultrasonic cleaner with an appropriate cleaning solution, which could be a mild detergent or a solution designed specifically for ultrasonic cleaning.
Placing Jewelry: Jewelry is placed in a basket or tray inside the ultrasonic cleaner. It's important to avoid letting the jewelry come into direct contact with the bottom of the tank to prevent scratching.
Activating the Machine: Once the machine is activated, ultrasonic transducers emit high-frequency sound waves into the liquid. These waves create millions of microscopic bubbles, which collapse in a process known as cavitation.
Cleaning Action: The implosion of these bubbles creates a scrubbing action that dislodges dirt, oils, and contaminants from your jewelry.
Finishing: After the cleaning cycle is complete, the jewelry is rinsed and dried.
This process is effective for cleaning even the most intricate jewelry, ensuring that your items are sparkling clean with minimal effort.
How to Clean Jewelry in an Ultrasonic Cleaner
Using an ultrasonic cleaner for jewelry is straightforward, but there are a few key steps to follow for optimal results:
Fill the Cleaner with the Appropriate Solution: Use a jewelry-safe ultrasonic cleaning solution mixed with water, or if you're using a general-purpose ultrasonic cleaner, choose a gentle cleaning fluid.
Place Jewelry in the Basket: Use the designated basket or tray to hold your jewelry. Ensure that the items are not touching each other or the bottom of the tank, as this could cause scratching.
Set the Timer and Temperature: Most ultrasonic cleaners have settings that allow you to control the cleaning duration and temperature. For jewelry, it’s typically best to clean for 3–10 minutes.
Start the Cleaning Cycle: Once the cycle is complete, remove the jewelry, rinse it with clean water, and dry it with a soft cloth.
Can You Mix Gold and Silver in an Ultrasonic Cleaning Machine?
Yes, it is generally safe to clean both gold and silver jewelry in an ultrasonic cleaner, but there are some considerations:
Gold Jewelry: Gold is a soft metal and can be affected by the high-frequency vibrations of an ultrasonic cleaner, especially if it has delicate stones or settings. If you're cleaning gold with gemstones, be cautious and ensure the stones are securely set.
Silver Jewelry: While ultrasonic cleaning is effective at removing dirt and grime from silver, it will not remove tarnish. For tarnish removal, you'll need a special polish or tarnish remover.
If you're cleaning a combination of gold and silver, it's best to clean them together, as long as both pieces are free from loose stones or delicate settings.
Will an Ultrasonic Cleaner Remove Tarnish from Silver?
No, an ultrasonic cleaner will not remove tarnish from silver. Tarnish occurs when silver reacts with sulfur or other elements in the air, leading to discoloration. While ultrasonic cleaners are excellent at removing dirt, oils, and grime, they don’t have the chemical properties needed to eliminate tarnish.
To remove tarnish from silver, you’ll need to use a silver cleaner or a polishing cloth designed to handle tarnish. However, ultrasonic cleaning can restore the shine and cleanliness of silver items, making them look like new again after tarnish removal.
(h2)What Solution to Use in an Ultrasonic Cleaner?

Choosing the right solution for your ultrasonic cleaner is essential for safe and effective cleaning. The right solution can ensure that your jewelry is cleaned thoroughly without damaging the surface or causing discoloration.
What Liquid Do You Put in an Ultrasonic Jewelry Cleaner?
For cleaning jewelry, it’s best to use a solution that is specifically designed for ultrasonic cleaners. These solutions typically contain mild detergents that are safe for metals like gold, silver, and platinum. You can also use distilled water mixed with mild dish soap for a budget-friendly option, though commercial jewelry cleaning solutions are always a better choice.
What Fluid Do I Use in an Ultrasonic Cleaner?
While jewelry cleaners are generally the go-to for cleaning jewelry, ultrasonic cleaners can also be used for cleaning other items, such as dental tools or industrial parts. Depending on what you're cleaning, you’ll need to select an appropriate cleaning fluid. For jewelry, use fluids that are formulated for delicate surfaces, while for industrial cleaning, you may need a stronger solvent or cleaner to remove grease and oils.
What Can You Clean in an Ultrasonic Cleaner?
Ultrasonic cleaners are versatile and can be used for much more than just jewelry. Here are some items you can clean with an ultrasonic cleaner:
Ultrasonic Dental Cleaning Machine
Dentists use ultrasonic cleaners to sterilize and clean dental instruments, such as probes, scalers, and forceps. The ultrasonic waves remove plaque, bacteria, and debris from the instruments without damaging them.
Ultrasonic Record Cleaning Machine
Audiophiles use ultrasonic cleaners to clean vinyl records. The ultrasonic waves gently remove dust and debris from the grooves of records, improving sound quality without scratching the surface.
Ultrasonic Industrial Cleaning Equipment
In industrial settings, ultrasonic cleaners are used to clean parts in machinery, automotive components, and electronics. The high-frequency vibrations can remove oils, grease, and dirt from even the most intricate parts.
Frequently Asked Questions (FAQs)
What Is the Best Frequency for Ultrasonic Cleaning Jewelry?
The ideal frequency for cleaning jewelry is typically in the range of 40–60 kHz. Higher frequencies, such as 60 kHz, produce smaller bubbles that are better for cleaning delicate surfaces and intricate details. Lower frequencies, like 25–40 kHz, are better for cleaning larger or heavily soiled items.
What Not to Put in an Ultrasonic Cleaning Equipment?
While ultrasonic cleaners are effective for many materials, there are some items you should never put in an ultrasonic cleaner:
Soft gemstones: Pearls, opals, and turquoise are too delicate and can be damaged.
Loose stones: Stones not securely set in the jewelry can come loose.
Enamel-coated or plated jewelry: The ultrasonic waves may damage the finish.
Will ultrasonic cleaner ruin jewelry?
When used properly, ultrasonic cleaners will not ruin your jewelry. However, if your jewelry has loose stones, delicate settings, or is made of soft materials like pearls, there’s a risk of damage. Always check your jewelry for fragility before using an ultrasonic cleaner.
