Not me, not yet anyway. But I've never needed to thus far. I still want to get an ultrasonic cleaner but have not that either. I would think it would shake out most nasty stuff if it got to that point. Granted if something breaks you still have to pull it down.

I got kinda far into my Walther PPS one day for some reason and it's no fun either. 1911, Ruger MK III, IV, AR is fine but I don't try to take those polymer pistols apart.
