A good tip for silencing a squeaky door!

A squeaky door can often be blamed on the pin that connects the two hinge plates. Use a hammer to tap a nail upward into the pin to push it out of the hinge, then pull it out the rest of the way. Coat the pin with full-fat mayonnaise before reinstalling it in the hinge. Open and close the door several times to distribute the luscious lubricant—and quiet the noise.
