I prefer Xylol (Xylene) for removing most sticky residues. BIG CAVEAT: make sure you wear nitrile gloves and only use it in a well ventilated area. This stuff is nasty. You can find it in most home stores in the paint aisle. I use it to remove the monokote adhesive that remains after I've removed as much as I can by peeling and peeling while applying heat. Takes it right down to the wood. Works alot like Ironex.
