I have recently had to remove Anti slip deck tape from my bikes belly pan. I used a product called Diggers Glue Rid contact adhesive remover. It's a jelly consistency, brush on and leave for 10 min wipe off and repeat, finally wash of the remains with Mineral Turpentine, then soap and water. Active ingredient 90% Xylene. You should be able to find a similar product in the US.
