GG's:

Acetone is often used to remove the wood oils when gluing Rosewood totes.  This
data point implies that Rosewood can survive a wiping with Acetone. YMMV: I've
only used it to prepare the surfaces of a broken tote.

"Goof Off" is a proprietary compound for cleaning wood, including removing
grubby fingerprints and paint spatters.  I've never tried it on motor oil,
though.

As I write this to my esteemed friends, I'm realizing that I've never actually
removed Motor Oil from a Rosewood, so I don't have any actual experience to
offer, only "theories!"
