Sail panels: need to remove the rear seat back and B pillar trim. To get the windows out I take out the 10 mm speed nuts and lay down in the back take my shoe off and use steady pressure pressed against the glass and it pushes out every time. Put your shoe back on and remove from the outside. Little easier if it sits in the sun for a bit to warm the urethane but it also makes more stringers.
But you can clean it up with brake cleaner or Goof Off.
