An ultrasonic cleaner is a cleaning apparatus employing ultrasonic waves, typically ranging from 20 to 400 kHz, in conjunction with a suitable cleaning solution, which can even be ordinary tap water, to efficiently clean delicate items. These cleaners are effective for removing contaminants like dirt, grease, oil, and more from a variety of materials, including metal, plastic, glass, and ceramics. They offer the advantages of automating the cleaning process, reducing cleaning time, and accessing and cleaning narrow or intricately detailed areas that are challenging to clean manually with a brush.
