Yes, that is exactly how ultrasonic cleaners are used, it basically gets abrasive on the surface (like scrubbing with like a hammering motion, but on a tiny level).
The size of the bubbles is determined by the frequency (the higher it is the smaller the bubbles with lower energy each, the lower it is the bigger are bubbles and more powerful each).
So, if you are cleaning a large flat metal sheet, then you can go lower frequencies to speed up the process, whereas you would want higher frequencies for more intricate objects so the amplitude is smol enough to get into all the tight spaces for bubbles to form.
38kHz is a very common for ultra cheap household various purpose cleaner (jewellery, fruit & veggies, glasses, delicate clothes, etc), I have a 50kHz buttplug shaped one (so you put in a container and is not itself part of one).
