Before another acetone soak, but after leaving it out in the Sun, I suggest you go after it with heat and a dessicant.

Cornstarch and a heat gun can remove lot's of oil. I play the heat over the wood just until the oil rises and starts to bubble, then smear with CS and wipe off. I repeat until no more oil bubbles up, then soak.

I prefer wood to plastic, leather to nylon, waxed cotton to Gore-Tex, and split bamboo to graphite.
