Have you tried shooting some WD-40 inside it?

Eeeeeeeek!!!!

Residue on glass surfaces! Damaged coatings!

And besides, the aperture blades are designed to be completely dry, no lubrication. It's unwanted lubricant on them that screws operation up. WD-40 would only momentarily liquidize the oily components, move them around, then dissolve,
leaving them more thoroughly spread around, along with its own residue.

Parenthetically, WD-40 seems to be widely misunderstood. It is not really a lubricant. It was developed for the military during WWII for the express purpose of water displacement, hence the WD name. It was the 40th formula tried, hence WD-40.

It's great for its intended purpose, and a not bad for loosening stuck things, mostly when they are stuck by dried out lubricants. The WD-40 solvents combine with the lubes to make them liquid again. But then the WD-40 solvents, far more volatile than the originals, soon evaporate, recreating the original problem. You spray the squeaky door hinges, they stop squeaking, for a few days, then need another spray, endlessly. Good the the makers of WD-40.

Yeah, I know, probably a dry wit joke. Still ...

Wit Less Moose
