This seems to be an ongoing request so I've started this new thread and put in my two bits worth in and hopefully others will follow with their remedies, not necessarily only for double sided tape residue. I have found Methylated spirits works not only on double sided tape but also on spray on glue I've been using to attach sound deadening material, that has finished up where it shouldn't have and a variety of other glues etc over a period of time with no adverse effects. . Other side benefits of Metho: is it will also clean vinyl surfaces and painted surfaces removing polishes, waxes and protectants, leaving you with a nice clean surface to work on.I understand there is a product I think called Prepsol, used by panel beaters an d pros that's pretty good.
