ultra-sonic gun cleaning

Great for stainless, but be very careful with blued and coated materials. Friend of mine took the finish off the frame of his Beretta 21 using an ultrasonic cleaner.
 
I have a medium sized one, so far not used. The chemicals that came with it says DO NOT use on alum...
 
READ and FOLLOW the directions that come with it.

Be aware that the gun parts will come out of the cleaner TOTALLY devoid of lubrication. That includes parts of the gun that you may not generally think of as being lubricated.

A friend of mine asked me for help with a Glock pistol that was jamming repeatedly. I noticed that the slide operation was very stiff and gritty feeling. Turns out that the "ramp" on the inside of the slide that the small "ear" of the connector rides against was totally dry. Glocks apparently don't like that. That's the area where the copper colored lubricant is applied at the factory. He had cleaned it with an ultrasonic cleaner and since that's not a point that is normally thought of as needing lubricant he hadn't put any there after the cleaning.
 
Mine does a great job of cleaning the entire gun apart from the bore, which still needs to be cleaned the old-fashioned way.

The water-based cleaner that came with my gadget left spots on a blued gun, so I poured it out, and now use good old Hoppe's No. 9. Caveat emptor: using flammable solvents in ultra-sonic cleaners means you've got to keep a very close eye on the temperature.
 
I would also want to keep it in a ventilated area to minimize fumes from getting into the electrical workings of the unit. Actually, that's a lie because I, personally, wouldn't risk using an ultrasonic cleaner with flammable solvent. But assuming I decided to take the risk, I would make sure it was in a well ventilated area.
 
Ultrasonic

I have one from Harbor Freight. I use it to clean my 1911. The entire gun fits when field stripped. I use a solvent for firearms that i found at Midway. (L&R Ultrasonics concentrate)
It works just fine. No issues at all other than a clean gun. It does have to be oiled again but that's a normal part of cleaning and maintaining.

The only experience I've had with ultrasonic cleaning was done as an experimental bases to a 50 cal blackpowder rifle that had been abused. The bore of this rifle was as 'leaded up' as I've ever seen in a bore.

I left solvent in the bore for a couple days to try to soften lead. Wire brushed bore and repeated with solvent/brush but just couldn't get barrel clean. Took barrel to friend of mine's gun shop where he put it in ultrasonic cleaner twice before it came clean. I was pleasantly suprised of results.
 
I use one, but I don't use the chemicals, I use Hoppes #9, so as to damage the bluing.
A lot of folks don't realize that you need a well ventilated area, so I run a fan near it to lower the potential of a flash fire and have fire extinguishers near by.
After running it, the parts really only need a wipe down.

Good point. I think there are also lubricating solutions designed to be used in ultrasonic cleaners. So you would clean the gun, let it dry (or blow it out with compressed air), and then run it though the ultrasonic again using the lubricating solution, blow out the excess, reassemble, wipe down and you're done.
