How to choose
Frequency selects the job.
Ultrasound cleans by cavitation — microscopic bubbles collapsing against the part. Lower frequencies make bigger, more aggressive bubbles. Higher frequencies make finer ones that reach into detail without touching the surface.
25 kHz
Coarse
Engine parts, castings, weld scale, heavy carbon. Aggressive cavitation on rugged metal.
Go to
37 kHz
Universal
The default for almost everything — instruments, tools, jewellery, workshop parts.
80 / 130 kHz
Fine
Optics, electronics, fine filigree and polished surfaces. Cleans detail without erosion.
