Looking to buy the best Ultrasonic Jewellery Cleaner? Check out our guide below and you’ll be well-placed to select the correct one for your needs.

Jewellery is becoming increasingly fashionable among both men and women these days. Regardless of which country you visit, you will notice people wearing cufflinks, bracelets, rings, earrings, brooches, and other similar accessories. Jewels are magical and may dramatically improve the appearance of any outfit; yet, in order for them to be effective, they must first be attractive.

Jewels are cherished for their ability to glitter and flash in a beautiful manner, but they must be handled with care. Of course, you can try to clean them with whatever you have on hand, but doing so may put your antiques at risk of being damaged or destroyed. If you choose, you can consult with an expert, but this will be expensive and time-consuming. Is there an alternate answer to this problem? There is, in fact, such a thing as an ultrasonic jewellery cleaner.

Using this technology, people would be able to clean their treasures in the privacy and convenience of their own homes. The best sonic jewellery cleaners can thoroughly clean all of your diamonds and valuable gemstones in a short period of time, restoring its brilliant flash and brilliance. The most crucial thing to note is that they do it softly and without causing any mechanical damage. Another factor contributing to their widespread use is the fact that many of these units are multipurpose, meaning that they can be used to clean not only gems but also other items such as watches, eyeglasses, discs, and other similar personal care items.

Buyer’s guide – What to keep in mind when buying an ultrasonic cleaner

When determining which ultrasonic cleaner to purchase, it is crucial to consider the kind of goods you intend to clean on a regular basis. According to your needs, the ultrasonic frequency, tank size, and cleaning cycle duration of the cleaner that is right for you will all be determined by this.

Check out how these considerations influence your decision on which ultrasonic cleaner to purchase.

Tank Capacity

When selecting an ultrasonic cleaner, the tank size, or more particularly the size of the basket within the tank, is one of the most significant considerations to make. Because you are unable to directly lay objects on the surface of the tank, the basket is responsible for limiting the size of the objects that can be cleaned.

It is critical that you can fit the largest item you intend to clean inside the basket and that it is completely submerged when the tank has been filled to its maximum fill level, which is recommended. It’s important to remember that you shouldn’t fill the tank all the way up. As an alternative, you should fill the tank with cleaning solution until it reaches the maximum level shown on the inside of the tank.

Cleaning frequency

If you’ve done any research on ultrasonic cleaners, you’ve probably realised that not all of them clean using the same ultrasound frequency. The frequency at which you should clean is determined by the type of cleaning you intend to do. The use of lower frequencies, such as 25 kHz, is appropriate for cleaning broad flat surfaces, but higher frequencies (80 kHz and above) are more suited for cleaning sensitive items.

For the majority of applications, frequencies in and around 40 kHz are an excellent choice since they provide a good balance between cleaning power and precision. As a result, the majority of ultrasonic cleaners on the market now work at a frequency of 40 kHz or lower. Unless you require very specialised cleaning, this is the frequency at which you should clean your home.

Heater function

The majority of liquid ultrasonic cleaning solutions perform best at temperatures ranging from 120 to 150 degrees Fahrenheit (50 to 65 degrees Celsius). For this reason, it is critical that the cleaner you purchase has a built-in heater in order to achieve the finest possible cleaning results.

One of the better options would be an ultrasonic cleaner with an adjustable heater, which would allow you to have complete control over how hot the cleaning solution gets. Thus, you may either match the temperature to the suggested temperature for the specific solution or experiment with several temperatures to find which one works best for the specific solution.

However, an adjustable heater is not always required, and any basic heater functionality is frequently sufficient.

Degas function

Degassing, or the removal of gases from a liquid (in this case, our cleaning solution), is essential prior to cleaning in order to achieve satisfactory results. Because there are no gases present in the solution, more ultrasonic energy will be directed toward cleaning the objects in the tank instead.

In most higher-end ultrasonic cleaners, there is a degas function that can be activated by pressing a button, which automatically degasses the solution. It is possible to accomplish this manually as well, by just running an ultrasonic cleaner for 5 minutes (preferably with the heating turned on) before putting the things in the cart.

Accessories

A variety of attachments are available for several ultrasonic cleaners, some of which are particularly effective for cleaning specific types of things. A cosmetic brush cleaning attachment is included with the iSonic DS310C-CE, and ultrasonic vinyl record cleaners are equipped with motorised fixtures that mechanically rotate records through the ultrasonic bath.

If you want to use your ultrasonic cleaner to clean a large number of the same sort of item, it may be beneficial to have a specialist accessory for that type of item included with your purchase.

Sweep mode

The use of an sonic jewellery cleaner with a sweep mode is very advantageous when cleaning delicate objects like jewellery. The sweep mode continuously changes the ultrasonic frequency, so preventing standing waves in the cleaning solution from occurring. For dead zones, which are places with little or no cavitation activity, and for hot spots, which are locations with a lot of cavitation activity, standing waves are responsible.

Hot areas can cause harm, especially when cleaning fragile things, so be careful when using heat. On the other hand, in dead zones, just a little amount of waste is removed.

Sweep mode will not be of much use if you do not regularly clean delicate things where precision cleaning is critical.

Tips and Advice on Using an Ultrasonic Jewellery Cleaner

Make sure the ultrasonic jewellery cleaner’s basket isn’t too full to achieve the optimum cleaning.

Some ultrasonic jewellery cleaners come with a complimentary cleaning solution; however, for the best results, you should add a few drops of liquid soap.

Allowing the pieces to soak in the solution for 4 to 5 minutes before turning on the machine is also said to help remove stains and long-term scale.

If you have any silver jewellery that has been tarnished, you will need to spend some time pre-cleaning it before putting it in the ultrasonic jewellery cleaning machine.

Always check the care manual for your ultrasonic jewellery cleaner to learn what can and cannot be cleaned in the machine.
Some machines won’t clean porous stones, while others won’t clean lenses that have been damaged or have any damage to the protective covering.

If you have any doubts about whether a certain piece of jewellery is safe to put in your ultrasonic cleaner, you should ask a professional jeweller.

After your jewellery has been cleaned in the ultrasonic machine, rinse it with water and either air dry it or use a can of compressed air to speed up the drying process.


Ultrasonic Jewellery Cleaner FAQs

Why should I buy a good ultrasonic cleaner?

A number of advantages are provided by the best ultrasonic cleaning devices, including the capacity to clean a wide range of different things. This contains everything from daily household products to jewellery, vehicle components, glasses and lenses, beakers and test tubes, dentistry and surgical equipment, and a plethora of other items. In general, an ultrasonic cleaner can be used to clean any hard surface consisting of ceramic, metal, glass, plastic, or rubber, among other materials. The cleaning process is extremely effective, eliminating dirt, dust, grime, oils, mould, fungus, algae, and limescale in less than ten minutes while reaching into even the smallest crevices that are difficult to reach with other cleaning methods and removing them completely in less than ten minutes.

Does ultrasonic jewellery Cleaner remove tarnish?

Chemical dips can help remove tarnish, but they can also harm the silver’s surface. Instead, a few minutes in an ultrasonic cleaner solution eliminates tarnish fast and safely.

Can you put fake jewellery in an ultrasonic cleaner?

Costume jewellery sometimes incorporates fake jewels and low-quality materials that can’t tolerate heat. The adhesive would very certainly degrade, and the stones would crack. This is why using an ultrasonic cleaner to clean costume jewellery is not suggested.

What liquid is used in an ultrasonic cleaner?

The first step in improving an ultrasonic cleaner’s cleaning performance is to use deionized water, which is a natural solvent. Because it is free of mineral salts and other contaminants, it is recommended. It’s also more reactive than regular water, and it won’t stain your clothes.

Can you put a diamond ring in an ultrasonic cleaner?

Although diamonds are extremely resilient, using an ultrasonic cleaner to clean them can be dangerous. The ultrasound vibrations can exacerbate internal faults, putting diamonds with substantial inclusions at danger of destruction.

Can you use vinegar in an ultrasonic cleaner?

People often report good results diluting vinegar with water to a 1:1 ratio when using it in an ultrasonic cleaner. Make sure to immediately rinse metals after ultrasonically cleaning them with vinegar.

How often can you ultrasonic clean jewellery?

You can clean your jewellery with the ultrasonic cleaner as many times as you want as long as it is safe to clean. In general, you should wash and clean your ultrasonic jewellery cleaner once every one or two weeks.

How long does an ultrasonic cleaner take?

5 to 30 minute ultrasonic wash cycles, in our experience, are common for a controlled and established cleaning process. However, pre-cleaning, rinsing, drying, and packaging operations may not be included, which would add to the entire cleaning cycle time.

How do you get the best results from an ultrasonic cleaner?

Heating the tank will improve cleaning outcomes and speed up the process – most solutions will need to be heated to operate as intended. On the solution packing, the ideal temperature setting for the device should be mentioned.

When should I change my cleaning solution?

You’ll find that it’s either taking longer to clean your parts or they’re not getting as clean as they used to. You can replace it if it starts to look or smell funny, but you may be sacrificing some valuable solution life.

How to Use an Ultrasonic Jewellery Cleaner

Remember to Heat It Up

When using an ultrasonic cleaner, one of the most typical mistakes is to fill the tank with cold water. The cleaning solution must be hot in order to be effective.

There are ultrasonic cleaners that come with a built-in heater to keep the solution warm. These devices, however, can be significantly more expensive than standard models.

All you have to do now is heat up the water before putting it in the tank (do not bring the water to a boil, though). The ammonia and dishwashing liquid can then be added.

The Cleaning Process

You can now place your jewellery into the tank after it has been filled with hot water and the cleaning liquid has been poured. To avoid scratching your jewellery, don’t put in too many items at once.

Turn the device on and let it running for as long as you need it to clean your jewellery. (This time varies from 1 to 20 minutes depending on how unclean the objects are.)

After the cleaner has finished cleaning your jewellery, turn it off and keep it inside for another 5-10 minutes so that the dirt particles that were knocked off by the sound waves can sink to the bottom of the tank.

After you’ve removed your jewellery, wipe it briefly with a soft brush to remove any remaining dirt, particularly from the mountings of your rings.

Rinse the objects and dry them with a gentle cloth to remove any residual detergent.

What You Should Not Put in an Ultrasonic Cleaner

An ultrasonic equipment should not be used to clean all jewellery.

Ultrasound may easily destroy many jewels. Softer gemstones, such as opals, lapis lazuli, emeralds, turquoise, and so on, should not be used.

Pearls, coral, and amber are examples of organic jewellery that can be destroyed.

Also, do not use your ultrasonic cleaner to clean gemstones that have had their colour improved by heat treatment.

Ultrasonic Cleaning Best Practices

When shopping for an ultrasonic jewellery cleaner, search for devices that give you as much control over these variables as possible. A microprocessor-based digital thermostatic control, for example, enables for continuous display of the solution temperature for close monitoring and control. The chemical activity of cleaning solutions is also increased by heat. The temperature of the solution should be regulated between 120 and 140 degrees Fahrenheit. If the temperature and time are controlled, it is possible to obtain repeatable cleaning consistency.

Adding a wetting agent or surfactant to the bath can help to lower the liquid’s surface tension. Cavitation strength will rise as surface tension is reduced. Ultrasound activity is best suited to medium vapour pressure. Low vapour pressure causes cavitation bubbles to burst with greater force, however this results in fewer bubbles and a higher cavitation threshold. High vapour pressure is ineffective because it causes more bubbles to form, but they collapse with less force due to a smaller internal/external pressure differential. Cavitation is facilitated by low viscosity. Intense cavitation with a stronger implosive force is produced by high density.

Never place parts or receptacles directly on the unit’s bottom. Because the parts will reflect the ultrasonic energy back into the transducer, the unit may fail (s). Allow at least one inch of space between the tank bottom and the beaker or receptacle for proper cavitation.

In a little benchtop cleaner, never use solvents. It is neither safe nor responsible in terms of the environment. Solvents quickly vaporise. Vapors of flammable solutions can collect beneath the device, where they can be ignited by electrical components.

When the beaker or tray is in position, keep the solution within one inch of the top of the device. When filled to within one inch of the top, units perform at peak efficiency.

Allow 5 to 10 minutes after turning on the equipment for the fresh solution to degas. This does not need to be repeated for subsequent uses because degassing is only required when the bath is freshly filled.

If a tray or basket is used to lower the pieces into the solution, it is preferable to use an open-construction holder, such as a mesh basket or an insert tray, that is suitably perforated for drainage. This also allows the sound waves unfettered access to the pieces.

To increase ultrasonic cleaning activity, replace cleaning solutions on a regular basis. As with most chemicals, solutions degrade with time. Solutions can become polluted with dispersed dirt particles, which settle to the tank bottom and interfere with ultrasonic transmission.
