Put on rubber gloves. Pour 1/4 cup of clear rubbing alcohol in a bowl. Add 1/4 cup of water.
Dip a white cloth in the bowl and then rub the cloth over the tape to moisten it.
Push the edge of a razor blade carefully beneath one corner of the tape. Grasp the loosened corner and pull it slowly from the granite. If the tape breaks, moisten the tape remaining on the granite and again push the razor blade beneath a corner to loosen it from the granite.
Wipe the cloth over adhesive residue remaining on the granite. Flatten the razor blade against the surface and gently scrape away the adhesive.
Moisten a fresh cloth in the alcohol-and-water mixture. Scrub away any remaining residue from the granite. Rinse it with plain water and dry with a dry cloth when you are finished.
