If you keep reapplying lubricant every few weeks or months to the same squeaky hinge or sticky lock, the issue is usually the wrong lubricant type. Here is why lubricants dry out and which products actually last.

You keep reapplying lubricant to the same squeaky hinge or sticky lock every few weeks, and it never seems to stick.

The problem usually isn't how much you're using. It's the wrong type of lubricant for the job.

Penetrating oils like WD-40 original were never meant to last. They evaporate fast and leave behind a residue that attracts dust.

This guide covers why lubricants dry out, and which products actually hold up over months instead of days.

Why Lubricants Stop Working

Wrong lubricant for the application: penetrating oils have a high evaporation rate. They penetrate corrosion and temporarily lubricate, but evaporate over days to weeks. If reapplication is frequent, this is almost always the issue.

Lubricant washing out: exterior applications expose lubricant to rain and temperature cycling. Light oils wash away. White lithium grease or chassis grease resists water and stays in place through weather cycles.

Contamination: in garage door tracks or sliding surfaces, lubricant picks up dust and debris over time, forming an abrasive paste. Once this paste forms, adding more lubricant makes it worse. Clean the track first.

Insufficient application: a thin spray coat on a dry hinge barrel lubricates only the surface. The pin-to-barrel contact point is inside the barrel. Open the door fully, spray directly into the gap between pin and barrel, then work the hinge to distribute.

How to Stop Lubricant from Drying Out

  1. Clean first: remove old lubricant and accumulated debris before applying new lubricant. A rag or brush removes most contamination.

  2. Switch to the right lubricant: white lithium grease for hinges, locks, and tracks. Chassis grease for automotive ball joints and suspension. Dry PTFE for dust-prone surfaces.

  3. Apply correctly: spray lubricants go into the mechanism, not on the surface. Hinge lubricant goes into the pin-barrel gap. Lock lubricant goes into the keyhole and gets worked in by turning.

  4. Use enough: a single spray coat may not be sufficient. For a dry hinge, apply, work the hinge 20 times, apply again, wipe excess.
