Old timer told me to use lighter fluid on a seized shutter. I tried it on a beat up Praktica and it actually freed things up.

So I got this Praktica L from a flea market for $10. Shutter was completely locked up, wouldn't budge. I was about to just toss it in the parts bin when this older guy at a camera swap meet told me to try a tiny squirt of lighter fluid on the shutter blades. I thought he was crazy but figured what the hell. Used a precision oiler with some Ronsonol, just a drop, worked it back and forth maybe 20 times. After about an hour the shutter started firing again. But now I'm paranoid about residue or long term damage. Has anyone else tried this trick or is it a ticking time bomb?

Watched a buddy do the same trick on an old Kodak Retina years ago and it worked fine, but he said after about six months the blades started sticking again and the lighter fluid had left a weird film that attracted dust. I'd flush it with some proper lens cleaner if you can get it in there, just to be safe.

Wait, it left a film that attracted dust? That's seriously alarming.
