If they were dried completely, I think it sounds logical that this would
work. Given that you're scraping off infinitesimal bits of dead skin and
hair that you might not even be able to see with the naked eye and that
might not rinse off in a simple water flow (how hard is it just to get the
"normal" visible gunk out? Since I don't shave every single day, my beard
hair tends to be longer and clogs up the blades pretty quickly), and that
that "gunk" will probably trap water against the blades and/or contain
remnants of your shave lotion/cream with who-knows-what in it that'll impact
the blades, getting them pristinely clean with ultrasonics presumably would
let them last longer.
I'm happy to test it empirically - as I said, given my current rate of
shaving, I switch blades every other month or so. I'll simply start keeping
track, and test it both ways. I have a professional (dental surplus)
ultrasonic cleaner in the bathroom that I use for jewelry.

I'll start with my next blade change, and should have results for you in
about 4 months. ;)
