I would get as much off as you can mechanically with toothpicks or similar wood or plastic probes, then follow up with a cloth or perhaps Q-Tips or more toothpicks sparingly moistened with a solvent like paint thinner.
If the finish is lacquer or shellac a petroleum a solvent like the thinner shouldn't damage it, OTH alcohol will attack shellac, and lacquer thinner will soften lacquer.
Though with either, just letting the solvent evaporate should get the finish back to where it was, assuming nothing like finger prints,dust or water (rubbing alcohol) gets in it during the process.
