That ultrasonic cleaner I was skeptical about saved me 4 hours on a set of fuel nozzles

I picked up a cheap 6-liter ultrasonic cleaner from Harbor Freight about 8 months ago, mostly because my buddy would not stop talking about his. I figured it was just a gimmick for cleaning jewelry. But last week I had a set of six fuel nozzles from a PT6 that were coked up pretty bad. I ran them through with a simple mix of Simple Green and water at 50 degrees C for 20 minutes each. They came out spotless, better than any solvent soak I've ever done. Has anyone else had good luck with these things on stubborn carbon deposits, or did I just get lucky?

Used to be a skeptic too, honestly thought they were just overpriced toys for cleaning jewelry and small parts. But a buddy of mine talked me into trying his on a set of old injector cups from a diesel engine that were black with gunk. After a few cycles with heated water and a drop of dish soap, they looked almost new. Now I'm looking at one a lot differently, especially since it's way faster than scrubbing each piece with a brush and solvent. Sometimes the simplest tools just work, no matter how gimmicky they seem at first.

Hold on, you cleaned diesel injector cups in an ultrasonic cleaner? That sounds like something that would just rattle the carbon off but not actually dissolve it. @julia843, I've got a buddy who tried cleaning some old brake calipers in one and ended up with milky fluid and pitted aluminum, so I'm real curious how your cups turned out that good.
