Previous owners installed decorative panes over double-paned windows, which have since fogged. These are not mullions. They appear to have a black caulk holding them in place. I'm told I can remove them myself (by the folks at Renewal Anderson), but I don't know where to start. They are not an Anderson product; they were put on after the original Anderson windows were installed. Any advice for what to try? What to research? I keep finding DIY on...
