Glycerin Soap

I really like the idea of glycerin soap as a sawblade lubricant!
That said, here is a link that Trevor might want to read:

Since this is not exactly a scientific analysis, it can be taken
just as additional but it is interesting.

What might also be taken as a possibility – since glycerin is a
recognized hygroscopic, maybe it draws moisture off the metal
sawblade (as well as out of the air)?

Or maybe (since I haven’t read the entire thread) it is the “soap”
that is helping the sawblades, not the glycerin?
