safe way to remove scotch tape residue from the inside of the soft top rear plastic window? I tried PASTIX which does a good job of cleaning, but it won't put a dent in the residue. Scared to try a petroleum based product like acetone or lighter fluid. Any proven method that will not damage the clear plastic?
