Ultrasonic cleaning refers to the process that utilizes ultrasound waves for agitating a fluid with a cleaning effect. Ultrasonic clearness is available in various sizes. These sizes range from small desktop units to industrial units, each with a respective capacity. The ultrasonic cleaning machine converts the sound energy of an ultrasonic frequency into mechanical vibrations. The device achieves this objective with the help of a transducer. The pace of the process depends on the object that is being cleaned. Usually, the cleaning process can take anywhere between 10-30 minutes—ultrasonic cleaners various clean things, including surgical and dental instruments. 

What is ultrasonic cleaner?

An ultrasonic cleaning machine uses high-frequency, high-intensity sound waves to remove foreign contaminants from surfaces submerged in an ultrasonically activated liquid. Goals can vary from one scenario to another. Sometimes, the machine facilitates the removal; sometimes, it enhances it. The term ultrasonic refers to the vibrations of frequencies above the upper limit of the human audible range, i.e., greater than 20 kilohertz. 


Identifying the materials suitable for cleaning with an ultrasonic cleaner machine is the first step in learning about the machine's applications. The majority of these materials are hard and non-absorbent by nature. Here, we are talking about metals and plastics in particular. Subject materials perfect for ultrasonic cleaning include electronic parts, cables, rods, and wires. The list doesn't end here; objects carved out of glass, plastic, aluminum, and ceramic are also deemed suitable for cleaning with an ultrasonic cleaning fluid. 

It is pertinent to mention that ultrasonic cleaning doesn't sterilize the objects it cleans. This is because the spores and the viruses can stick to the surfaces despite ultrasonic cleaning. Hence, one must not rely on this machine for sterilization purposes. That is why sterilization follows ultrasonic cleaning in the medical applications of this machine. Ultrasonic cleaning gets rid of contamination from the industrial equipment too. Pipes and heat exchangers are an essential pick in this category, as are specific other critical industrial sectors. These include the sporting, printing, pharmaceutical, and engineering industries. 

How does ultrasonic cleaning work?

The object that needs to be cleaned is placed in a chamber that contains a solution. This solution can be either aqueous or organic; the nature depends upon the application. An ultrasonic transducer, a component we will discuss in detail in the next section, generates ultrasonic waves in the fluid. The generation of ultrasonic waves leads to the development of compression waves in liquid tanks. Compression waves technically tore the liquid apart. As a result, millions of microscopic bubbles are produced; the phenomenon is referred two as cavitation. These bubbles collapse and high temperatures and pressures are achieved due to this collapse. But because they are microscopic, the impact is nothing more than cleaning and removing contaminants from a particular surface. The higher the frequency is, the more superbly the objects are cleaned. The cleaning solution that is often used for maximizing the effectiveness of the procedure features different formulations but is primarily a hydrocarbon-based solution.

The components of ultrasonic cleaners

An ultrasonic cleaning machine has three essential components. These components include an ultrasonic cleaning tank, an ultrasonic generator, and an ultrasonic transducer. Let us talk about these components briefly in this section. 

The ultrasonic cleaning tank is responsible for holding the ultrasonic cleaning fluid and all the items that need to be cleaned. As is evident from its name, the function of the tank is quite easily understandable. However, we would like to focus more on the ultrasonic transducer, one of the most critical components of an ultrasonic cleaning machine. 

The transducer is a device that can generate ultrasonic vibrations. Dipping deep into the transducer's composition, it consists of an active element, a radiation plate, and a backing. The active component for most ultrasonic cleaners is a piezoelectric crystal. The piezoelectric crystals can convert electric energy into ultrasonic energy, courtesy of the piezoelectric effect. Briefly speaking, the product refers to the change in the size and shape of crystals when they receive electrical power. The backing is a thick material that absorbs the energy radiating from the back of a piezoelectric crystal. The transducer's radiating plate converts ultrasonic energy to mechanical waves in the fluid. 

Add ultrasonic generator refers to a power supply. The generator can transform the AC electrical energy from a power source to electrical energy. The converted electrical energy is enough for energizing a transducer operated at an ultrasonic frequency. Summarizing the generator working principle, it serves electrical power to the transducer, which transforms energy into mechanical waves in the cleaning fluid. This transformation facilitates the vibratory cleaning action of the machine. 

What are the benefits of ultrasonic cleaners? 

Following are some of the key benefits of using an ultrasonic cleaner:

1- The environmental impact of using an ultrasonic cleaner is significant. Considering the terrible effects associated with heavy chemical cleansers, ultrasonic cleaners provide a very environment-friendly solution, courtesy of the water-soluble detergents they use for breaking up the residues. 

2- Workers operating an ultrasonic cleaner are not at risk of inhaling harmful chemical fumes. Furthermore, they have not posed the risk of injury associated with the sharp instruments often used in such settings. 

3- Ultrasonic cleaning is a perfect choice for cleaning delicate items. Precision instruments often require a thorough cleaning. An ultrasonic cleaner produces the perfect cavitation effect, which permits water and detergent to enter the narrow crevices. Removing the residues becomes a lot easier this way. 

4- Ultrasonic cleaners are handy for cleaning a wide range of applications mentioned in this brief. 

5- Compared to conventional cleaning methods, ultrasonic cleaners use much less water and electricity. These traits make them super-efficient.

What frequencies are used? 

25 kHz, 40 kHz, 80 kHz, 120 kHz, and higher. This summarizes the frequencies often employed when using an ultrasonic cleaner. Usually, the frequencies can range between 15 kHz to 400 kHz. However, ultrasonic cleaners rarely operate at such extremes. Typically, the best frequency for ultrasonic cleaning applications is 40 kHz. However, this number can vary from machine to machine, from situation to situation. 

Factors to consider before buying ultrasonic cleaners

Ultrasonic cleaner tank size

The tank size is one of the most critical features because the parts that need to be cleaned have to be immersed in the cleaning solution. Typically, single application ultrasonic cleaners feature custom-sized tanks.

Ultrasonic frequency

As we know from the discussion so far, ultrasonic cleaners operate over a variety of frequencies. Which frequency suits your purpose? It is a question that must be answered carefully before purchasing a machine. Forty kilohertz is the optimal frequency, so most buyers go with it.


The ultrasonic cleaners you are buying must produce enough ultrasonic waves to fill the cleaning tank. In case the power of the cleaner is too low, uneven cleaning takes place because of the development of dead spots. Probably, ultrasonic cleaners have the correct power levels automatically set. But if you buy different components separately, you have to adjust and ensure the optimal power levels yourself.


It might be a good idea to purchase a machine that allows you to set a timer for longer cycles. Similarly, any ultrasonic cleaner with a digital display and interactive user interface is a perfect pick.


Ultrasonic cleaners that use heat energy are the way forward for someone looking to remove heavy kinds of contamination. Heat energy is helpful in softening the residues, making them particularly easy to remove. In addition, if you are heating things just below the boiling point, you can rest assured that all the contamination will be removed. Usually, the optimal temperatures for ultrasonic heat cleaners are around 100 Celsius.
