Removing Eternabond residue

I purchased a 2007 Trail Cruiser about 3 years ago and it is time for some roof maintenance, although I see no leaks. The previous owner had the edges of the roof taped with 4" sealing tape; Eternabond or some other brand. Then the entire roof was coated with acrylic sealer. The tape job done was rather sloppy and it is coming loose in places and the sealer is peeling in a few spots.  A dealer states that sealing tape is meant to be temporary and suggested self leveling sealer at the joints after removing the tape.                                                                          My question is: after removing the tape (with a bit of heat applied) and gently scraping the adhesive underneath, what kind of solvent to remove the remainder of the adhesive without damaging the rubber roof underneath? A number of solvents will cut this sticky adhesive, but I don't want to compromise the EPDM roof. Thanks all!
