Here’s a quick way to silence a squeaky door hinge. Close the door then use a hammer and nail set to tap out the pin in the offending door hinge. Wipe the pin clean of any grease or grime with a cloth, and scrape off any caked-on paint. Then, buff the pin shiny with 120-grit sandpaper. If you find any burrs or rough spots on the hinge pin, file them smooth. Apply a thin bead of machine oil along the shaft of the pin, then tap it back into the hinge.
