One thing that has not been mentioned so far is heat. I've treated old aperture sights with Kroil or with mineral spirits (The "mildest" of solvents commonly found in a hardware store). Then after a few days to allow soaking in if they are still locked up, applying heat (I'd suggest a hair dryer). I've had sights that would not yield to solvent loosen up after a bit of heating.
I have a newly acquired ultrasonic cleaner. I may try that and a Simple Green/water bath the next time.
