Thanks for guessing. Seriously that's as much as the rest of us are 
doing. Lanolin is there originally, as we all know, there to keep the 
fibers from drying out and becoming brittle. David Stanwood has said 
that he wood prefer damper felt not to be too white looking, a sign 
that that particular processing schedule specified cleaning the 
fibers too much. (Quite likely, your acetone wash.)
