Removing gunk on a McCobb  

I purchased a McCobb Planner Group captain's chair, in the dark stained maple, and there's some clear gunk, an adhesive perhaps, on the seat. Not a very large area, but it's got to go. I've done my best with the Goo Gone, and my trusty thumbnail, but there's still a trace of it. What I'm seeing in the filings does not include anything from the finish, so far so good. But what next? I am heading to the hardware store to pick up some 0000 steel wool, and will try it on the underside.
But I'm hoping one of you can recommend something.
Thanks!
