I used to repair high dollar pneumatic assembly tools for J.I. Case. Having one of these cleaners is handy in dealing with the cleaning of intricate, small parts. I use Simple green or mineral spirits as a cleaning agent, they work well with loosening rust, corrosion or dirt.
I have one I'd bought from Harbor Freight ten years ago for my shop and after changing the power switch one time, it still hums along.
If you don't expect miracles out of the thing, they'll have a place in the tinker's shop.
I have extensive experience using them as a SCUBA repair technician. I, too, used them with Simple Green as the immersion agent. Itís important to understand that they are merely a first step in the cleaning process and not an all-in-one complete solution. They are slow but effective, often requiring the part to be left submersed overnight. The real cleaning comes after removing the part from the ultrasonic bath.
Iv'e used them with prety good results in the finish industry for cleaning paint from air caps, etc. I also have a harbor freight model that I haven't run yet. I'd like to try the hornady fluid. If that dosen't pan out, I may try the simple green route. It does need a little follow up wiping or brushing on the parts. I would like to use it to like on the BCG on the AR.
DZ, which case plant did you do work at? I used to service the finish line at Case Burlington IA. I never took care of Goodfield as it wasn't in my territory.
I have one I got in trade from a dentist. I use it filled with Eds Red no acetone formula. It does clean but takes much longer than I thought. On the order of an hour for a badly fouled action of a silenced pistol. Like other I don't think it is a be all end all but it does clean in places you can't see. My mosquito will weep Ed's Red for a couple days after cleaning. I do not recommend you use a water based cleaner as you will never get all the water out.
