If you've got a door hinge that squeals every time you open the door, we've got the fix for you! A little petroleum jelly will rid the hinge of that annoying wail. The petroleum jelly works its way into the hinge and adheres well, so it won't run off and make a mess like oil or other lubricants.
Photos 1 and 2 show how to punch out a hinge pin and grease it up. After all the hinges have been lubricated, open and close the door a few times to work the petroleum jelly into the hinge joints.
