Acetone is imo the best way as it actually melts away the glue and basically your left wityh a clean bead after....baking works but leaves a chunky bead of old glue....baking breaks the bond between the rim and tires....the glue notmally sticks to the tire which can be a Pain to deal with when the glue cools and becomes Rock hard......Boiling i found also didnt remove the glue it just broke the bond between one or the other....Acetone with the Tire elevated out of the liquid is IMO the best way and gives you a clean bead to work with when you go to mount it again.
