Tried a drop of lighter fluid on a sticky shutter and it actually worked
I had a Pentax K1000 in my shop last week that had a shutter stuck open at 1/1000. I was about to tear the whole thing down to clean the blades because every trick I tried - compressed air, tiny brush, even a static charge - did nothing. Then an old guy at the camera club in Tulsa mentioned he uses Ronsonol on stubborn oil residue. I was skeptical lol, but I dabbed a tiny bit on a cotton swab and touched just the edge of the blade pivot. After letting it dry 10 minutes, the shutter snapped back like new. Anyone else ever tried lighter fluid for shutter cleaning or is that just a cowboy move? I feel like it could warp something long term.
