Tried a cheap ultrasonic cleaner on some injector nozzles and it wrecked two of them

I grabbed a $60 cleaner from Harbor Freight last week thinking it would save time cleaning some old PT6 fuel nozzles. Ran it for 10 minutes with standard solution and two of them came out with visible pitting on the orifices. Learned the hard way that not all ultrasonics are fine enough for aviation work especially on critical parts. Anyone else run into this with budget shop gear?
