I finally tried ultrasonic cleaning on a seized shutter and it backfired
Had a beat up Canonet QL17 with a stuck shutter, threw it in the ultrasonic bath with 50/50 distilled water and ammonia solution for 10 minutes like I read on a forum. Came out the shutter blades were fine but the glass on the viewfinder had this weird haze that would NOT wipe off. Guess the solution got past the seals, now I gotta replace the whole finder assembly. Anybody else wreck a rangefinder this way or did I use too much heat?

holy crap, that haze thing sounds brutal. i've run a few old lenses and bodies through the ultrasonic but never with ammonia, just a tiny bit of dish soap. i bet the heat made the solution thin out and seep into stuff it shouldn't have. sorry about your finder man, that's a total nightmare.

My buddy did that same trick with ammonia and an old Pentax, fogged the prism so bad he used it as a paperweight.
