A Philco I couldn't resist

I guess there are a lot of solvents of different forms that will solve the problem, but the key thing is to be quick about it, and get all of the solvent off after it has done its job. This will minimize the damage to the original finish.

Again: In my experience mineral spirits is #1 at the task over all. It will slowly and safely do the trick, and generally leave the old finish unharmed.

I worked for many years in a retail music store where we refurbished and resold used organs, pianos, and other wooden cabinet instruments, and this was always the standard drill for all the trade-ins we received that we had to make presentable to new owners. Mineral spirits always worked well in cleaning up woodwork of the residues of Scotch tape, decals and other abuses of the finish. And the finish was always left unharmed.
