I finally tried ultrasonic cleaning on old shutters and it felt like cheating
I always figured dunking a shutter assembly in a machine was lazy work, stuck with my brushes and canned air for years. Last month a beat-up 1970s SLR with sticky blades came in, and after 3 tries with traditional methods I gave the $80 ultrasonic tank a shot. That thing stripped years of gunk off in 5 minutes and the curtain timing came back spot on, no partial disassembly needed. I still hand clean the mounts and screws first, but now I'm wondering how many other so-called shortcuts are actually worth adopting. Anyone else switch over and never look back, or did you have a bad batch that ruined your trust in it?
