A squeaky door is a two-minute lubrication job done properly, or a recurring annoyance done with the wrong spray. The difference is grease versus solvent.

Classic WD-40 is mostly a solvent and water displacer, not a lasting lubricant: it silences a hinge today and evaporates within weeks, which is why the squeak keeps returning. What hinges want is something that stays put: white lithium grease, silicone spray, a PTFE ('dry') lube, or in a pinch, a smear of petroleum jelly - even bar soap rubbed on the pin outlasts WD-40.
All of these cost a few dollars and one tube or can will service every hinge in the house for a decade. If WD-40 is genuinely all you have, use it to clean the hinge - that is its real talent - then follow with a proper grease once the pin is dry.
Close the door and work one hinge at a time so the door never leaves its frame. Tap the hinge pin upward and out using a nail or thin screwdriver against its bottom tip and a few light hammer taps. Wipe the pin clean - the black paste on it is metal dust mixed with old oil, and it is half the squeak.
Apply a thin coat of grease to the pin, drop it back in, swing the door a dozen times to spread the lube, and move to the next hinge. Wipe off the squeeze-out so it cannot catch dust. Do all hinges even if only one seems noisy - the others are next in line, and you are already standing there.
Painted-over or rusted pins need persuasion: score the paint seam around the knuckles with a utility knife, give the pin tip a drop of penetrating oil and ten minutes, then tap again. Truly seized hinges can be lubricated in place - work silicone spray into the knuckle joints from the top while swinging the door - but a removable pin always produces the longer-lasting fix.
A squeak that survives clean, greased pins usually means hinge wear or misalignment: look for shiny rub marks where knuckles meet, and check for a sagging door binding in its frame. The first fix for sag is free - tighten every hinge screw. If a screw spins uselessly, the wood thread is stripped: pack the hole with a couple of wood-glued toothpicks or a matchstick, snap flush, and re-drive the screw into the new bite.
If the noise happens as the door rubs the frame rather than as it pivots, that is friction, not hinges: look for a shiny rub line on the door edge or frame, often at the top corner of a seasonally swollen door. Light rubbing gets a paraffin/candle-wax rub on the contact line; heavier binding gets the latch-side screws tightened first (which can lift a sagging corner), then sanding or planing of the marked spot as the last resort.
Creaks from the latch side when the door is pushed while shut are the strike plate flexing - tighten its screws and bend the tab slightly if your latch has one. And a door that groans at the floor is dragging on its threshold or a high board: visible scuff lines on the threshold confirm it, and the fix is hinge-tightening before any trimming.
Lubricated with actual grease, a hinge stays silent for years - so the maintenance schedule is nearly nothing: a once-a-year pass through the house's hinges (doors, gates, garage side door) with the lithium tube takes fifteen minutes and ends squeaks as a category of problem.
Exterior doors and gates deserve the marine-grade or PTFE option since rain washes lighter lubes out, and their pins benefit from a wipe-and-regrease each autumn. If a hinge needs re-lubricating more than annually, it is worn - solid brass or ball-bearing replacement hinges cost a few dollars each, fit the existing recesses, and turn heavy doors silent and smooth in a way grease never quite manages.
Petroleum jelly is the best stand-in - it stays on the pin. Bar soap or candle wax rubbed on the pin also works. Cooking oils technically silence a hinge but oxidize gummy and attract dust; skip olive oil unless it is truly the only option.
No - that is the point of working one hinge at a time. The other hinges hold the door while each pin is out. The door only comes off for hinge replacement or planing.
Humidity and temperature change wood and metal dimensions: doors swell and rub, hinge tolerances tighten. The fixes are the same - grease the pins, wax the rub lines - and seasonal squeaks usually signal it is rubbing somewhere, so check for shiny spots on the door edge.
Stick-on felt or rubber bumpers along the strike side of the frame soften the slam; a wrap-around foam draft seal does the same while sealing air. For doors that drift closed on their own, that is a plumb problem - tightening the top hinge often fixes the drift too.
