ROFL "Bears dislike the scent of pine-based cleaners" !!! I can see how that would be annoying living in the woods!!
After seeing the highly bear ripped backpack in the Smoky Mountain National Park ranger station, I think I would want to pour a ring of pine oil around my campsite about 50' radius from the center of camp, AND carry a bear mace can in my belt clip.
Or, find a nice place to camp where there were log cabins. Canvas is not bear proof at all.
