Ive been using lighter fluid (it wasnt Zippo, but another brand name, that comes in a bottle type to refill lighters) and it has worked great. I used in on a page from an 1846 atlas that had been taped to a mat, as well as on 1920s and '30s post cards (both smooth and linen texture finish cards), and it has worked like a champ.
Ive put a small amount in a shot glass then used a small brush or cotton swap to dab it on the areas, letting it soak into the tpae residue and paper. Then carefully and slowly removing the tape with a pair of tweezers.
Ive sometimes done a a 2nd application to remove any remaining glue residue, which can turn sticky if its that old kind of clear, cello tape.
And it wont stink you out of your flat.
It also evaporates quickly, so i had to add to my shot glass (it was maybe 1/3 or less full). The smell isnt that strong to begin with --- benzene, though, has a much stronger smell, so you might want to crack a window for air circulation, if you use that, instead.
