When we lived in our old house in Pine Hill (guess where the name came from!!!)we all used rubbing alcohol on cars, kids' toys, lawn furniture, hanging laundry, etc.
Toothpaste and a flea comb, non-toxic! Seriously, the toothpaste is a tiny bit abrasive and breaks the sap down, and the flea comb removes it. These are also items that you have on you, in the hotel room or the car in the parking lot at the showgrounds!
