The reason spray oil never fixes a squeaky door is that the noise isn’t coming from where you’re spraying.
A butt hinge is two leaves with interlocking knuckles and a steel pin running through them. Every time the door swings, those knuckles rotate against the pin. When the film of grease between them wears away, metal grinds on metal and the whole door panel acts as a soundboard. That contact surface is inside the knuckles, sealed away from anything you spray at the outside.
Get to the pin and the squeak stops properly.
Where the squeak actually comes from
Step 1 Find which hinge is actually squeaking Swing the door slowly and have someone else listen, or run a hand lightly near each hinge. Most doors have three and usually only one is the problem — treating all three wastes time and makes mess.
Step 2 Lift the pin part way out Open the door and wedge something under it so the weight is supported. Put a nail against the underside of the pin and tap upward until the head lifts clear. Take one pin at a time and only part way — do not remove all three.
Step 3 Grease the pin itself, not the outside Wipe the exposed pin, then coat it with white lithium grease, silicone grease or petroleum jelly. This is the surface that rubs. Spraying the outside of a hinge never reaches it.
Step 4 Tap it back and work the door Push the pin down and tap it flush. Then swing the door fully open and closed ten or fifteen times to spread the grease along the full length of the pin.
Step 5 Wipe the drips and check Run a rag down the hinge and the door edge to catch anything that ran. Swing it once more. If a squeak remains, it is a different hinge — repeat there.
Isolate the hinge first
Most internal doors have two or three hinges and usually only one is squeaking. Doing all of them means three times the mess for no extra benefit.
Swing the door slowly through its full arc and listen. If you can’t tell, have someone else swing it while you put a hand lightly near each hinge in turn — you can often feel the vibration before you can locate the sound.
The top hinge is the usual suspect on a heavy door, because it carries the most load.
Getting the pin out
Support the door first. Open it, and slide a wedge, a folded magazine or your foot underneath so its weight isn’t hanging off the hinge you’re about to disturb. This matters more on heavy or external doors.
Then take a nail, a thin punch or a slim screwdriver, hold it against the underside of the pin where it protrudes below the bottom knuckle, and tap upward with a hammer. Light taps. The pin will start to rise and the head will lift clear of the top knuckle.
Only lift it part way — an inch or two is plenty. You want access to the pin surface, not the door on the floor.
What to put on it
This is where most fixes fail.
Use these:
- White lithium grease — the standard answer. Thick, stays put, doesn’t evaporate.
- Silicone grease — good, and won’t stain if it runs onto a painted frame.
- Petroleum jelly — genuinely fine, already in most bathrooms, and it doesn’t drip.
Avoid:
- WD-40 and similar spray solvents. They’re designed to displace water and free seized parts, not to lubricate long-term. They thin the old grease, work brilliantly for about a week, then evaporate and leave the joint drier than when you started.
- Cooking oil. It goes rancid and gummy.
Wipe the exposed pin clean with a rag first — there’s usually black grit on it — then coat it generously along its length.
Back in, and work it
Push the pin back down and tap it flush with the hammer. It should sit with its head resting on the top knuckle, same as before.
Then swing the door fully open and closed ten or fifteen times. This isn’t optional. The grease is only on the part of the pin you could reach; working the door drags it down through the knuckles and spreads it across every contact surface. The squeak usually disappears within the first three or four swings.
Wipe down the hinge and the door edge with the rag to catch anything that ran.
If it still squeaks
It’s a different hinge. By far the most common answer. Go back and isolate properly.
It’s not the hinge at all. Two impostors sound almost identical:
- The door rubbing the frame. Rub chalk or a soft pencil along the door edge, close it, and open it again — the chalk transfers where it’s touching.
- The latch dragging on the strike plate. Turn the handle fully and swing the door; if the noise vanishes, it’s the latch, and a little grease on the strike plate sorts it.
The pin is seized. Penetrating oil, fifteen minutes, try again. If it still won’t move, stop. A whole replacement hinge costs very little and is a far better outcome than a snapped pin in a knuckle you can’t clear.
Done properly, this lasts years — which is the difference between fixing the squeak and repeatedly silencing it.

Questions people actually ask
Why not just use WD-40?
Because it is a water-displacing solvent, not a grease. It quietens a hinge for a week or two because it thins the old gunk, then it evaporates and leaves the joint drier than before — so the squeak comes back worse. Use an actual lubricant that stays put: white lithium grease, silicone grease, or in a pinch petroleum jelly.
Can I do this without removing the pin?
You can get a partial result by dripping oil onto the top of each knuckle and swinging the door to draw it down, and it is worth trying first if the door is heavy or awkward. But the pin surface is where the noise comes from, and reaching it directly is the difference between a fix that lasts a week and one that lasts years.
The pin will not budge.
It has corroded in place. Spray penetrating oil where the pin enters the knuckle, wait fifteen minutes, and try again. Tap upward from below rather than levering from the top. If it still will not move, leave it — a seized pin is not worth breaking the hinge over, and hinges are cheap to replace whole.
It still squeaks after greasing.
Two likely causes. Either you did the wrong hinge, which is common — go back and isolate it properly. Or the noise is not the hinge at all but the door rubbing the frame or the latch dragging against the strike plate. Rub a little chalk on the door edge, close it, and see where the chalk transfers.
Do I need to take the door off?
No, and you should not. Removing all the pins means the door comes down, which turns a ten-minute job into a two-person job with a real chance of damaging the frame. One pin at a time, part way out, door still hanging.
