ANYWAY......lol there shouldn't be an issue..I'm cleaning a precision piece of equipment in a machine designed to clean precision equipment. As long as I change the fluids before cleaning a far more precise machine,like a watch lets say, there is no issue.
So the results are in, I can clean an injector.

There is still some discoloration but that would need some caustic chemicals that are way to strong for my gear. The parts are clean and major deposits have been removed. You can see that the nozzle body is still pretty bad. In this case there was corrosion that has pitted the steel very badly and there is no way to save it. The needle on the other hand looks good and I would reuse it. I would make these nozzles if it wasn't so cheap to buy them. I have to do a better job than they did! Just look at the tool marks! LOL Never would have passed my degree.
Anyway, I would consider cleaning up a set if somebody wants me to.
