DAG 154 is available from Schaff Piano Supply, and elsewhere(?). It's a 
brush on liquid graphite suspension for bridge caps, jacks, spring grooves 
and the like. No grease. When dry, it burnishes to a nice shine. Nice stuff.

That's what I had assumed until Steve Grattan posted this:

I've lost track. Ethelene Glycol is, I think, and Polyethelene Glycol (PEG) 
is used for soaking green wood for working it without it drying out and 
splitting. I could do that Google search I'm always suggesting to others, 
but it's not that pressing.
