Sure hard to beat wiping it down with a cloth dampened a bit automatic transmission fluid.
All those special gun oils mentioned, and several others, will work just fine. Probably as good as automotive transmission fluid.
I see what you've done there and I agree. I once looked up the whms forms, patent's and so on for many of the well known lubes. I found it safe to say they they are nothing more than individual concoctions, sharing one common ingredient...ATF. Scents, dies, maybe some solvent thinner here and there, but all pretty much the same.
