Ultrasonic power is one of the decisive factors. Ultrasonic cleaning machines emit ultrasonic waves through transducers. The more vibration heads there are, the greater the power, the better the cleaning effect, and the shorter the required time. If you are cleaning small household items such as glasses, watches, jewelry, makeup brushes, etc., and the objects to be cleaned are dust, oil stains and other dirt, then usually 3 to 5 minutes is enough. But if the object to be cleaned is large and the dirt is thick, it won't be too much. Generally, in industrial cleaning, 15 to 30 minutes is sufficient. When the ultrasonic power is too weak, it is no longer a matter of whether the cleaning time is long or short; it is very likely that the cleaning will not be thorough. The cleaning machine is just like our washing machine, merely a tool. The effect of plain water is definitely not that good. Generally, for ordinary cleaning of glasses, watches, and jewelry, adding a little household detergent works quite well. Or, based on the degree and nature of the stains on the objects to be cleaned, choosing industry-specific cleaning solutions yields the best results. So, no matter what items you clean, you need a cleaning agent to play an auxiliary role, so that the cleaning effect can reach the ideal level. Then, what frequency and power are generally required for household use?

      The preferred frequency for home use is 40/42KHz, suitable for cleaning household items such as glasses and jewelry. Its moderate penetration and density not only ensure the cleaning effect but also do not damage the surface of the objects. Finally, there is the thickness of the dirt on the object to be cleaned. If it is an item that has not been cleaned for a long time or even never, In this way, the cleaning time will need to be a bit longer.

In summary, the duration of ultrasonic cleaning is determined by the dirt of the object to be cleaned itself. Choosing a cleaning machine to use is the most important.
