Yes. Ultrasonic cleaners can be very close to magic if properly applied.

Mine gets very little use, but the top, conveniently glass for would-be
viewing, is all crazed/micro-fractured?
Is that common with such cleaners, partially self destructing?
If I want to see whats going on, I have to find a piece of glass or
perspex to cover over the dancing fluid fountains.

I should have said , with the damp tissue test, showing yellow staining
on the tissue. Also locked-in , meaning makers trying to defeat cart
refilling, to force purchase from them.
Another tip, I don't see with ink refill kits, they always seem to say
drill in . That must leave plastic swarf inside. I use a conical
soldering iron tip at the breather hole , to melt in. Then when closing
, a short length of spaghetti tube inserted and then hot melt glue
around it and marginally into the plastic of the cart, so easily pulled
away the next time.
My current work printer, an HP something or other, does not have the
inkjets in the cartridges. I only use black ink and so only refill the
one cart. Instead of drilling a hole I add the ink through the
absorbent pad on the bottom of the cart that delivers ink to the
printer head. I add ink one drop at a time and it is fascinating to
watch it soak in. The ink spreads across the complete pad surface
almostly instantly and then soaks in almost as fast. As the cart gets
fuller the ink is absorbed more slowly so it is easy to tell when the
cart is almost full. Much easier than my home printer where I have to
add ink through a drilled hole using a syringe.

A b&w laser no-ink printer does seem like the best bet.
