I use an L&R ultrasonic cleaner occasionally (Use their cleaning soln & sometimes simple green)
http://www.lrultrasonics.com/industries/weapons/weapon/hcs200.html
Their process recommends a few minutes in the cleaner
Hot water rinse
Blow off with compressed air
then a few more mins in ultrasonic lubricant pan that is separately placed above the main cleaning solution just touching so waves ~ penetrate.
This few mins with their liquid lubricant has inhibited rust in my glocks/sig internals.
I still lube with Tw25 or CLP where appropriate but that lube bath lets mefeel better about the hot water.
I do recommend their system but I will admit :
I still have to scrub bores but if I do it before ultrasonic it gets them
ready for a few lube/dry patches ONLY after the wash/lube cycles)
I still have to do work on face of revolver cylinders
(I brush them with a serious solvent, rinse henm straight into ultrasonic cleaning)
I still have to brush breechfaces
If I do that with solvent pre-treat, whatevers left wipes off later with a patch
but it cuts the time required to do all of those & has never caused me issues
with Sigs (even alloy frame 220)
Glocks
Smith & W revolvers & a 1911
Does great with my MAK90 bolt/carrier
My ps90 innards
etc
