Some ultrasonic cleaners come with accessories that are particularly useful for cleaning certain types of objects. For example, the iSonic DS310C-CE comes with an accessory for cleaning makeup brushes, whereas ultrasonic vinyl record cleaners come with motorized fixtures that automatically spin records through the ultrasonic bath. Industrial Ultrasonic Cleaners: As the name suggests, this type is mainly reserved for industrial applications, featuring heavy-duty transducers and generators that produce massive wattage. Most buyers won’t need something this large and powerful, with the cost being exceptionally high compared to other devices. The iSonic P4875II+MVR10 is one of the best ultrasonic record cleaners on the market. The machine holds up to 10 records at once, which makes it ideal for cleaning large collections. Its motorized fixture automatically rotates the records as they are being cleaned. Not only is there minimal labor involved in cleaning, but with 10 records at a time it will be finished in no-time. An ideal solution if you have a lot of records to clean, but don’t want to spend all of your time doing so. Reduction of surface tension increases cavitation, so the solution usually contains a good wetting agent ( surfactant). Aqueous cleaning solutions contain detergents, wetting agents and other components, which have a large influence on the cleaning process. The correct composition of the solution is very dependent upon the item cleaned. When working with metals, proteins, and greases, an alkaline detergent solution may be specifically recommended. Solutions are typically heated, often around 50–65°C (122–149°F), however, in medical applications, it is generally accepted that cleaning should be at temperatures below 45°C (113°F) to prevent protein coagulation that can complicate cleaning. In fact, a lot of the problems I have listed for these at home scalers are also true for professional cleaning. The at home scalers move fast enough to cause damage, but not enough to be effective!
Warranty is another crucial consideration when buying these machines. Make sure you understand what your warranty covers and doesn’t cover. You also need to avoid machines without a warranty.

Ultrasonic cleaning is used to remove contamination from industrial process equipment such as pipes and heat exchangers.
In addition, Niemczewski studied the effect of the pH of the cleaning medium on the cleaning effect and concluded that the addition of sodium sulphite makes the medium less alkaline and more effective in cavitation [ 82]. For further exploration, Niemczewski and Kołodziejczyk analyzed the cavitation effect with an acidic solution between 1% and 7% ( w/ w) and found that a gradual increase in the acidic concentration significantly increased the intensity of the cavitation effect [ 83]. Kim directly explored the collapse mechanism of cavitation bubble rupture from the microscopic level and found four oscillation behaviours, including volume, shape splitting, and the chaotic oscillation behaviour of cavitation bubble ruptures [ 84].
De-ionized water: it is great for cleaning all kinds of material-metals, plastics, rubber, glass, and fabrics. Ultrasonic cleaners are used to clean many different types of objects, including industrial parts, jewelry, scientific samples, lenses and other optical parts, watches, dental and surgical instruments, tools, coins, fountain pens, golf clubs, fishing reels, window blinds, firearm components, car fuel injectors, musical instruments, gramophone records , industrial machined parts, and electronic equipment, optical lenses, etc. They are used in many jewelry workshops, watchmakers' establishments, electronic repair workshops, [2] and scientific labs. The combination of chlorine dioxide and ultrasound can effectively improve the cleaning effect of ultrasound. For example, studies have shown that when chlorine dioxide and ultrasound were combined to clean apples, bacteria was effectively removed from the surfaces [ 89]. Milan-Sango also tested the same combination of washing methods for the inhibition of E. coli and Salmonella, and the results showed a significant reduction in the microorganisms associated with bean sprouts [ 77]. Similarly, Zhao et al. used this technique to treat plum fruits for 10 min, and the experimental results showed that it effectively extended the shelf-life of fruits and reduced the loss rate of vitamin C and flavonoids [ 11]. Hot spots can cause damage, especially when cleaning delicate items. In dead zones on the other hand, not enough gets cleaned.Non-thermal plasma (NTP) is a disinfectant produced by dielectric barrier discharge, plasma radio, and corona discharge [ 104]. Charged particles that bombarded microorganisms in NTP can directly destroy their proteins, nucleic acids, and other macromolecules, resulting in the death of the microorganisms [ 105]. Active substances in NTP (such as reactive oxygen species, free groups, etc.) react with proteins and nucleic acids in microorganisms, disrupting the normal function of the microorganisms [ 106, 107]. Ultrasound became a new concept in 1922 when the definition of ultrasound was first introduced. Ultrasound technology has developed rapidly since the 1950s and is receiving increasingly close attention. Ultrasound applications can be divided into two main categories: low-power ultrasound for ultrasonic testing and diagnosis and high-power ultrasound for the performance and state of materials, such as ultrasonic cleaning, welding, processing, grinding, and atomization [ 1, 2]. Ultrasonic cleaning has become the most widely used high-power ultrasonic technology. It has gradually expanded from its initial tight application in machinery and electronics to emerging areas such as the medicine, food, chemical, aerospace, and nuclear industries [ 3, 4, 5]. The principle of ultrasonic cleaning lies in the ultrasonic waves generated in water to produce enough “cavitation bubbles” and the release of energy to complete the cleaning operation. Ultrasonic cleaning is also known as “brushless cleaning” due to its unique cleaning method [ 5].
For most applications, at and around 40 kHz is a great option and a solid middle ground between cleaning power and precision. This is why most commercially available ultrasonic cleaners operate around the 40 kHz frequency. Unless you need to perform very specialized cleaning, this is the frequency to go for. Heater function It is well known that the texture, flavour, colour, and other characteristics of washed fruits and vegetables are the main aspects affecting sensory evaluation. In terms of texture, ultrasonication can change the texture by altering the microstructure of the fruit and vegetables; in terms of flavour, the free radicals generated by ultrasonic cavitation are expected to reduce the off-flavours of the food; in terms of colour, ultrasonication has no strong oxidizing properties compared to disinfectants and has no effect on the colour of the fruits and vegetables [ 46]. Alexandre found that strawberries treated with ultrasound (35kHz) retained 16% more firmness than samples washed with water [ 50]. A restricted number of studies have found that ultrasound can catalyze the degradation of off-flavours in wine [ 46]. Alexandre discovered that the colour of the strawberries was maintained by treating them with ultrasound (35 kHz) for 2 min compared to other treatment methods [ 50].But regardless of their effectiveness, the same advice applies about them having the potential to damage your teeth and gums, and therefore I don’t recommend using them: Although ultrasonic cleaning has many advantages, it is not devoid of defects, such as noise during cleaning. The problem of cavitation noise is not sufficiently pronounced in small machines but is particularly prominent in large industrial production. Therefore, eliminating or reducing cavitation noise is the focus of future research work. For cavitation phenomena, we can study the specific cavitation conditions of different materials and discover the optimization environments needed to reduce surface roughness. Ultrasound may cause undetectable damage to the interior of fruits and vegetables and it is recommended that these are identified by ultrasonic flaw detection techniques.
Cleans in the hardest to reach spots. The ultrasound waves in the cleaning solution reach places that you otherwise would not be able to reach by hand. The ultrasonic cleaning process works through acoustic cavitation. This is a process that creates tiny imploding bubbles on a microscopic scale. When these bubbles implode, they generate forces that create a cleaning effect.Ultrasonic cleaning is used widely to remove flux residue from soldered circuit boards. However, some electronic components, notably MEMS devices such as gyroscopes, accelerometers and microphones can become damaged or destroyed by the high-intensity vibrations they are subjected to during cleaning. Piezoelectric buzzers can work in reverse and produce voltage, which may pose a danger to their drive circuits.
