Just realized my old way of cleaning aperture blades was making things worse

For years I'd use a cotton swab with a tiny bit of lighter fluid, but last week I tried a proper synthetic brush and a drop of naphtha instead. The blades moved smoother and left zero residue, which was a huge upgrade. Anyone got other tips for sticky aperture mechanisms on old SLRs?

What about that trick @cameronmurray mentioned with the alcohol and a toothpick?

My buddy in Seattle swore by using a tiny drop of pure isopropyl alcohol on a toothpick for his Pentax. Said it evaporated clean and fixed the stickiness right up.
