The ultrasonic cleaner – clean and reliable cleaning
Who doesn't know the problem – the glasses are dirty and cleaning under the water jet or with a cloth simply doesn't produce the desired result. Or the jewelry has to be cleaned properly until the last angle. An ultrasonic cleaner is the perfect everyday assistant and cleans almost all small objects quickly, easily, carefully and also gently.

What was an ultrasonic cleaner?
An ultrasonic cleaner is an electrical device for cleaning small and complex objects. These products are used in a wide variety of situations.
In medicine, for example, dental prostheses and braces are cleaned, surgical cutlery is reliably cleaned and individual components are freed from paint residues, oil and dirt in the workshop area. Wherever dirt and crustings settle into the smallest cracks and holes, the ultrasonic cleaner is a probatch tool for effective cleaning. Motorcycle mechanics have long recognized this and treat additional carburetors in professional ultrasonic cleaners.
But ultrasonic cleaning devices are also enjoying increasing popularity in office and home use. They are used to clean drawing sticks, print heads, glasses, braces, jewelry and other objects.

How does the ultrasonic cleaner work?
Schematic setup of an ultrasonic cleaner: 1. Cleaning fluid, 2. Cavitation bubbles, 3. Implodiating cavitation bubbles, 4. Concave insert, 5. Housing with stainless steel trough, 6. Swing elements, 7. Ultrasound generator, 8. item to be cleaned, 9. Dissolved dirt particles.
The function of a cleaning device with ultrasound is based on the principle of cavitation. To do this, the object to be cleaned must be in a cleaning fluid. As a rule, water is used for this purpose. With the help of vibration elements (plate oscillator), pressure and suction waves are generated in the water. As the name suggests, the frequency of the pressure and suction waves is in the range of ultrasound. Ultrasound is the range, or above 18 kHz, and thus above the upper ear clip of the human ear.
While the pressure wave displaces the water, the suction wave produces numerous cavitation bubbles. These bubbles are in principle cavities filled with steam. Due to the constant change between compression and expansion, the bubbles grow rapidly until they implode in the expansion phase.
The resulting bubble produces a locally limited pulse with extremely high suction power. If a cavitation bubble implodes in the immediate vicinity of the object to be cleaned, the dirt particles are removed from the surface. The cleaning process is continued continuously due to the continuous formation and implosion of the cavitation bubbles.
To increase the cleaning performance, soap or cleaning concentrates can be added to the water. In addition, some ultrasonic cleaning devices also offer a heater, which °can heat the ultrasonic bath up to approx. 80 C.
Important:
Never switch on the ultrasonic cleaner if there is no water in the stainless steel pan! After inserting the objects to be cleaned, add the water to the maximum mark.
What are the different types of ultrasonic cleaners?
Ultrasonic cleaning devices generally all work on the same basis, but was not meant to be different. Depending on where the individual ultrasonic cleaning devices are used, the size of the devices differs above all. It is clear that the products for home use are much smaller than those used in the automotive industry. After all, the objects to be cleaned here are much larger.
The most important differences are the filling quantity, handling and performance. The higher the volume, the larger objects can be cleaned in the ultrasonic cleaner. For larger models, which in turn are used for cleaning larger objects, the performance should also be higher.
The handling is usually quite simple, so that the individual ultrasonic cleaners often differ only in the extra functions, such as the timer, the heating or the division of the tub.

What are the advantages of ultrasonic cleaners:
Cleaning up to the rearmost angle
The biggest advantage of an ultrasonic cleaning device is the deep pore cleaning of areas that are not accessible with conventional tools such as brushes, brushes or rags.
Gentle and thorough cleaning
The surfaces of the device to be cleaned are not attacked if handled correctly. The cleaning process is carried out throughout, whereby no areas are omitted.
Environmentally friendly cleaning
In most cases, plain water is sufficient for gentle cleaning. Cleaning additives are only required for extreme and stubborn dirt.
Different capacity
Ultrasonic cleaners are available in different sizes to suit individual requirements.
Simple operation
Ultrasonic cleaning devices are generally quite simple to operate. The effectiveness or the success of the cleaning can be seen by the turbidity of the water.
Wide range of uses
An ultrasonic cleaner can be used to clean many objects that may also come into direct contact with water. However, cleaning complete wristwatches is strongly discouraged.

What was to be observed when purchasing an ultrasonic cleaner?
If you have decided to clean small and complex parts with the ultrasonic cleaner in the future, you should pay attention to a few things before purchasing, so that the device finally corresponds to your own ideas.
The capacity
The filling quantity refers to the tub volume and thus to the size of the device. This should be based on the objects to be cleaned in the future. While normal sizes are usually sufficient for household use, larger ultrasonic cleaners are used mainly in industry, in order to be able to clean larger objects and components reliably.
Power
The power must be matched to the capacity. If you buy small devices, a rather low performance is sufficient. However, the larger the volume, the higher the performance should be set, in order to continue to clean the objects reliably and easily.
The application
When buying a new ultrasound device, prospects should make sure that it is easy to use. However, this does not only refer to the operation, but also to the installation and the initial assembly.
FAQ - Frequently Asked Questions about Ultrasonic Cleaners
Can several items be cleaned at the same time?
Simultaneous cleaning of several objects in an ultrasonic cleaner is no problem. However, it is important to always ensure that all objects are completely covered by water and do not protrude from the water bath.
What was to be done if small parts were falling through the basket?
If the parts to be cleaned are so small that they fall through the mesh of the basket, a metal tea strainer is helpful. The sieve with the inner small parts is then simply hung in the cleaning fluid.
Do ich necessarily need a concentrate for my cleaning device?
Generally not, but if some cleaner concentrate is added to the water, the cleaning performance increases. Depending on the application, dental cleaners or disinfectant cleaners are recommended.
What is the advantage of a built-in timer?
With adjustable timers, the cleaning time can be adjusted individually to the parts to be cleaned. In doing so, one can fall back on already made empirical values. Fixed safety timers prevent the parts to be cleaned, such as glasses or jewelry, from being treated for too long and from being damaged.
What is the effect of the frequency on an ultrasonic cleaner?
The ultrasonic frequency affects the size of the cavitation bubbles. The higher the frequency, the smaller the bubbles. And the smaller the bubbles, the better they can penetrate into the smallest cracks and corners. Small ultrasonic cleaning devices for jewelry and glasses usually have higher vibration frequencies than large ultrasonic cleaners with several liters of water content.
What is the performance of an ultrasonic cleaner?
The size of the cavitation bubbles depends on the frequency and not on the power. But the larger the stainless steel cleaning vessel or the capacity, the more power is needed to swing the water.
How is the ultrasonic cleaner cleaned?
After the cleaning bath, the water must be tilted out in the ultrasonic cleaner. It is then important to wipe the interior and the complete exterior housing with a lint-free and soft cloth and to dry them. The device is then ready for use again.
Conclusion – this is the perfect ultrasonic cleaner
It is important to pay attention to the items to be cleaned when purchasing and to select the device according to its size. If these are larger objects, not only the filling quantity of the stainless steel pan should be higher, but also the performance of the model.
