sonic cleaning old shutter


New Member
I am cleaning a TLR mamiya 80 mm lens and was wondering if it is safe to sonic clean it, using a ultra sonic cleaner that you normally use for jewellery and watches. Not just the slow gear escapement (which i cleaned wiht lighter fluid but it is simply is not clean enough). So i was thinknig in drowning the whole thing (without the glass ofcourse, just the bare shutter mechanism with the aperture blades) in the ultrasonic cleaner.
1. Anybody has any experience with that ?
2. What cleaning solution to use then
3. If not recomnended.... why would it not work ?
