Hot soapy water is the safest way to remove sap. I work in a body shop where we let the car sit in the sun til hot, then wash it with scalding soapy water.
I used dry gas to remove sap from my car and it works well. I soaked a paper towel and gently rubbed it on. I let it soak in for about 1 minute and rubbed it off. Then I rinsed the area with water where the dry gas was used.
I've found the best thing for removing any kind of pine sap from your vehicles is WD-40. Just spray it on, let sit about 5 minutes, and then wipe off. We used to have a cabin in the pines and that's the easiest way we found to remove the sap.
