Citrasolv and an old fingernail brush got 90% of it. Also took off some paint near the bottom where the wood got water-damaged before we bought the house, so I got to cross off “remove the oil” and got to add, “patch rotted wood, repaint the trim, and get the damn storm door installed,” to the list for this summer. But I think I got enough off that I won’t have to worry about the next coat sticking.
