Are you tired of hearing your door squeak every time it is opened or closed? If so, read on because this is one of the simplest of all household fixes. Squeaks are caused by friction, so repairing them is simply a matter of lubricating the hinge.
First try spraying the butts of the hinges with a light coat of penetrating oil (such as WD-40). If that doesn’t work, pull out the hinge pin from the squeaky hinge. To do this, use a screwdriver to pry up the top of the pin or, if necessary, drive a punch or long nail up from the bottom of the hinge barrel with a hammer to pop the pin out of the top of the hinge). Be ready to support the door when you pull out the hinge pin, particularly if the door is a heavy one.
Next, lightly scrub the pin, barrel, and hinge leaves with steel wool. Coat them with a thin layer of silicone spray or a light penetrating oil, and replace the pin.
Keep a door working well by periodically lubricating the hinges with silicone spray or a light penetrating oil. But don’t spray this type of lubricant into a lockset—it will gum it up.
