Remove the door from its hinges. Start by tapping out the hinge pins. Once it’s off its hinges, move the door to a workspace to begin sanding.
Using the power planner, sand down a 32nd of an inch off the top of the door and a 32nd of an inch from the side of the door. Start with the blade outside the edge of the door; once you start trimming, keep the blade in motion until you reach the other edge. Stopping in the middle can cause an uneven trim.
Seal the edges by spraying them with hairspray, and re-hang the door.
