Boy, you guys are funny, especially when it comes to photos of abominations. Anyway...
I have and use an ultrasonic cleaner on all my guns and also ones that I work on to put food on the table. It is not cheap and is not cheap to use, but it will clean a gun (or parts thereof) in less time and with less physical effort (no scrubbing with brushes) than anything I have ever seen, used, or heard of. If there is gunk it can't get off (like serious lead cladding), it will help loosen it considerably...then an overnight soaking in really light Chevron oil, then repeat with the ultrasonic the next day. Beware though that usonic treatment can dissolve sight dots and marks and painted logos and such, and possibly damage Tritium inserts (never tried it, afraid to). But when they come out of the tub, high-pressure rinse in sink with hot water, blow-dry with air compressor at 100psi, and proceed to lubrication. Parts come out bone dry with no lubrication at all, so rust is your enemy.
I always clean a brand new gun this way. I bought an NIB S&W .40 Sigma (yeah-yeah) that had a lot of crud in the barrel from the test-firing. Usonic'd it and lubed it, and it was clean as a whistle. Just make sure to inspect the bore very carefully for pits, bulges, or rings.
And, please, no more fugly fotos!
