Thanks for the upload! They are much more useful than the one I received.
George: Thanks for the offer. As you know, I got the file from Mike.
I was not keen on mineral spirits just from a personal exposure perspective. I used 99% isopropyl alcohol (IPA). It removes solvent well AND evaporates quickly. Since it is just one compound, rather than a mix, it should all evaporate, rather than leave a less volatile compound from the mix behind.
To be clear, IPA is also hazardous, but less so than mineral spirits.
