Old timer at the shop swore by using lighter fluid on sticky shutters
There was this guy Frank who worked on cameras since the 60s, told me to use Ronsonol lighter fluid to clean sticky shutter blades. I thought he was crazy but tried it on a beat up Canonet I had sitting around. Worked like a charm, blades freed up in like 2 minutes with no residue. Has anyone else used lighter fluid for shutter cleaning or is that just a weird old trick that somehow works?
