Any felt, leather, or cloth that got wet with the stuff is trash. Count on replacement. > Will the glycol with additives creep alongthestrings into the tuning pin > block? I doubt it, but the stuff sitting on the strings will absorb moisture and rust the strings. Not that long ago, some tooners used to use ethylene glycol for pin dope. > I think the soundboard and bellyrail will be ok—right?

Without seeing it: Thorough cleaning of soundboard and keybed, and a realistic evaluation of whether that looks to be good enough to continue.
