Old trick for sticky aperture blades blew my mind
Had a Pentax lens with aperture blades stuck from oil. Heard about using lighter fluid to clean them. Thought it was a bad idea. Tried a tiny drop on a swab and it worked perfectly. No residue, blades snapping fast now. Anyone else use this method?

It's not worth the risk honestly, lighter fluid can leave microscopic residue that attracts dust later and some coatings might react badly to the chemicals. Has anyone actually tested this on old glass where the lube has dried out completely?

Wow, I always thought lighter fluid would wreck the lens, this totally changed my mind.
