the dasheild on my car was always lifting itself up with the use of the attached double adhesive tapes. so my dad used rugby to put it in place.
i want to remove it and have it cleaned, and if i feel like it, i want to remove it completely.

however, the rugby stains are already all over the dashboard. is there a way to remove them without damaging the dash? solvents that can melt the rugby might discolor the dash to some extent so i'm getting opinions. hopefully, a DIY solution would do it, otherwise, i'd have to go detail.

thanks!
