I recently discovered a small spot on our couch that appeared to be pine sap from our kids playing outside. Using a cotton ball, I dabbed and gently rubbed rubbing alcohol onto the spot. It very quickly started to disappear. I then let the couch dry. There was a slight water ring type spot left behind that came off easily with a baby wipe. Now there is no sign of any pine sap being on the couch. Yay!
