more trouble with my 95 gp

alright another issue i've been meaning to tackle, ever since the summer after my A/C broke the Louisiana heat has completely melted my dash board area around the radio and steering wheel area, i dont even care about how it looks, but the stuff on the dash that melted never quit firmed again. its just a black muck paste, that gets stuck on everything. especially my nice clothes. i've tried putting different things on it to keep it from getting me messy but everything just slides off eventually. even sign vinyl. im totally at a loss. i'd sell the car right now for next to nothing..
