Hi Styckbow,
I have used old reliable: Lighter fluid! Done this many times to remove tape residue. Any brand will work. Just put directly on the bow and rub the goo off with a piece of old towel (terrycloth). Works great. I always wipe the bow down with a damp rag after though, to remove any smells.
I would advise you to stay away from strong solvents (acetone, mek etc.)
Even using lighter fluid, I would do this outdoors or in a well vented area, (naturally, away from flame or sparks! LOL)
Good luck,
Harry.
