A great read, well argued and researched.

I will just say I have used 99.5% isopropyl, purified petroleum, and white spirits/naphta, and for me the Isopropyl seems to work the best. I use compressed air to blow it out, and it has “saved” two “Frozen Facits” already. Not disputing anything, I’m just wondering - does the stuff really have water in it? And if so, wouldn’t using compressed air solve that issue so to speak? The stuff I use is made for cleaning electrical components. :)
