Last summer seemed to be a really bad year for pine sap. I had it all over my boat and I noticed a lot more pine cones on the ground than usual. I used hand sanitizer to get it off my boat and boat cover. It came off the boat fine but I still have spots on my mooring cover where the sap was even though I got the sap off. My poor dog was always picking at his paws last summer because he had sap on the pads of his feet.
