Default ultrasonic cleaner

I want to buy an ultrasonic cleaner for cleaning liquid spilled motherboards. It's basically a small vat that you place the board into it and it cleans it.

Do you guys have any recommendations?

I've used industrial grade ultrasonic cleaners with proprietary cleaning fluid 20-25 years ago. Worked well for bearings and precision parts.
I bought a small (folded eyeglass cleaner size) cheap consumer product that uses water, which is nothing to take seriously.
No idea concerning motherboards. Hope you can find one thru industrial surplus, good ones were expensive, back then.

Not particularly. Obviously, you'll need a large one. It should fit the board *comfortably*, since you want good cleaning over the whole surface, and you can't fold the board.

They're generally not at that frequency anyway, but be sure your cleaner's frequency is far from the 32.768 kHz RTC crystal. A powerful on-frequency excitation source would damage it.

And I presume you know to use deionized/distilled water.
