To thoroughly clean your pine cones, you will need to first soak them in a water-vinegar solution. The solution will help kill bugs, as well as loosen and remove any dirt and debris. Once they are finished soaking, they will be ready to bake. Bake your pine cones for an hour to an hour and a half, or until they have re-opened. Then let your pine cones air dry for two to three days.
