Unpopular opinion: Isopropyl alcohol might be doing more harm than good on old shutters
I had been cleaning sticky shutter blades with 99% isopropyl for years. Then last month I tackled a 1950s Mamiya and the alcohol actually made the blades curl up. A vintage repair guy told me those old lubricants dissolve and expand into the gaps. Now I'm split between continuing with alcohol for newer stuff and switching to Ronsonol lighter fluid for anything pre-1970. What do you guys use on really old shutters without wrecking them?

Didn't you find the lighter fluid leaves a weird film though?

That lighter fluid film always made my chicken taste like a gas station bathroom. I switched to a chimney starter and never looked back. Total game changer for under 20 bucks.
