The 8 Best Ultrasonic Cleaners in 2023 – Top Rated Picks

An ultrasonic cleaner is a tool used to clean a wide range of objects: mainly, it is used with dentures and jewellery, but it is also very useful with industrial products.

It has the appearance of a washing machine and is equipped with a tank, which is filled with water and, if necessary, with the specific detergent according to the objects to be cleaned.

We had selected the best ultrasonic cleaners that are present below.

Things to Consider Before Buying Ultrasonic Cleaner

How to Use the Ultrasonic Cleaner

The ultrasonic washing machine manages to clean various types of objects in depth, thanks to the generation of high and low-frequency waves; the waves are conducted by the water and the detergents that are associated, through a process called cavitation.

The objects to be cleaned are introduced into the basket. The detergent is chosen based on the type of dirt to be removed: cleaning can be achieved with various chemical agents.

The alternation of high and low voltage also creates an alternation of temperature, up to a maximum of 70 °: this is precisely what allows a deep and detailed cleaning. It can operate on battery or electricity. In the more technological models, the temperature can be set manually.

Once the settings have been activated, cleaning can be started by pressing the appropriate button. The time required to complete the cavitation varies according to the case: to find out more, just consult the instruction booklet.

Depending on the amount of dirt to be removed, it may be necessary to perform multiple cleaning cycles for the same object.

A device of this type is particularly suitable for cleaning dentures, for which a special detergent is available. Washing with the ultrasonic cleaner must always be preceded by a good and thorough brushing.

Using an ultrasonic washing machine offers numerous advantages: it is a fast machine, which acts in depth and guarantees complete cleaning without any effort.

How to Choose the Ultrasonic Cleaner

In order to choose the best model of ultrasonic cleaner on sale, it is good to know what are the aspects that must be taken into consideration when buying. Among these, there is the capacity of the container, the power of ultrasound, compatibility with the objects and commands available.

Container Capacity

The tank capacity depends on the type of object to be cleaned and on its size. The smaller one reaches a maximum of 600 millilitres, the larger one exceeds 20 litres. For those who have to use it purely at home, a good compromise could be the 2-litre one, not too bulky, but still quite capacious.

Power of Ultrasound

The ultrasonic power is expressed in watts and expresses the maximum degree of cleanliness that can be achieved. Ultrasonic cleaners from 6 litres upwards can reach ultrasonic powers of 200 Watts and more.

To make the right decision, you have to consider the size of the objects to be cleaned and the level of consumption that you don’t want to exceed.

Timer and Adjustable Temperature

Not all ultrasonic cleaners have the same controls; the more technological ones allow you to manually select the washing time and temperature and then view them on an LED display.

Detergents

Ultrasonic cleaners are not always compatible with all chemical agents and, therefore, with all detergents. It is good to make sure which substances can be introduced in the model at your disposal, before proceeding. The ideal is to buy a versatile model that can meet all needs.

Alkaline solutions are ideal for cleaning stainless steel, metals, zinc, tin, copper and cast iron, but also ceramics, glass and plastic materials. Acid solutions are used to remove oxides from metals.

Deionized water is used for cleaning all types of materials, metals, plastics, rubber, glass and fabrics. Finally, the are specific to eliminate waxes, heavy greases, cast iron and stainless steel.

The Advantages

Whoever gives importance to the price because he does not want to spend too much, must evaluate the advantages deriving from the use of this machine, with the aim of choosing a quality product anyway.

It is also suitable for beginners because it is very easy to use, releases very few chemical charges and reduces costs as it allows you to spend little time for thorough cleaning.

There will not even be the need to purchase accessories separately because to preserve the bottom of the container just use PVC or metal baskets to contain the products to be cleaned. In short, with a small expense, it is possible to obtain good results without efforts.

Against Dirt Particles

Do not delude yourself that you have removed the dirt, you have removed only the one immediately visible and sometimes not even that. If the bulk of the work can be done with alternative cleaning methods, to remove the very small particles it is essential to use the ultrasonic cleaner.

Fill the Pan

The cleaner pan must be filled with water up to its maximum level which you find clearly indicated. The water must reach a temperature of 70 °.

The Choice of Detergent

The choice of detergent is not second-rate and must be made taking into account, among other things, the substance that constitutes the dirt to be removed. Once you have added the cleaning solution to the water, give it a stir.

Place the Objects

The objects to be cleaned must be placed gently inside the basket. In the case of watches, special supports can be used, which are not always included in the ultrasonic cleaner package.

Maintenance and Safety

The secret to keeping the functions of any appliance intact over time is to perform proper maintenance at regular intervals. It is therefore advisable to do a weekly or monthly review of your ultrasound cleaner, reviewing all its components to check that there are no anomalies.

It is also important to take some precautions and comply with the basic safety measures to avoid incurring unpleasant accidents when using the ultrasonic washing machine:

• Disconnect the machine from the power before turning it over to empty it from the liquid in the tank. Care should be taken during the operation to avoid spilling fluids near the electrical outlet or the control panel
• It is necessary to clean the immersion tank at regular intervals: the dirt generated during the cleaning process could settle on the bottom of the tank and weaken the action of the sound waves, making everything less effective
• Change the filters of the ultrasonic cleaner often to prevent them from clogging and impairing operation.

We also recommend using water-based detergents, as those that contain solvents are not suitable for ultrasonic cleaning and could damage the steel of the immersion tank, as well as being harmful to health.

In addition, it is always better to manually remove excess grease and dirt from objects before immersing them in the liquid for ultrasonic cleaning, to prevent larger particles from dispersing inside the tank and being collected by the filters, clogging them.

Direct exposure of the hands or other parts of the body to cavitation can cause tissue and bone damage.

Those who do not have sufficient knowledge in the electronics field to be able to identify any problems can contact the expert and qualified personnel who are able to verify the condition of the appliance.

It is best to avoid doing DIY repairs on ultrasonic cleaners that operate at a very high voltage, as they are very dangerous for those who do not know where to get their hands.

Similarly, the tank of the ultrasonic cleaner must never be filled with alcohol or other flammable liquids: the vaporized particles inside the ultrasonic cleaner could in fact cause an explosion and release harmful gases into the environment.

A further precaution concerns the way in which ultrasonic cleaners are stored. It is good practice to avoid exposing them to prolonged periods of excessive heat, as well as dust.

Excessively humid rooms can help to wear the components of the ultrasonic washing machine quickly: it is, therefore, advisable to protect it with a special cloth cover.
