You’ve been doing it wrong. Spraying WD-40 on squeaky hinges temporarily silences them but actually accelerates wear by stripping away protective grease. A locksmith explains the science behind the squeak and reveals the surprisingly simple fix that lasts for months.
For years, a quick spray of WD-40 seemed like the perfect solution for squeaky hinges—until a repairman revealed it was actually accelerating damage. A worn hinge pin, a proper lubricant, and ten minutes of work can restore a sagging door and prevent costly repairs.
That squeaky hinge isn’t just annoying—it’s telling you something important. WD-40 provides only temporary relief because it doesn’t address the real culprit: a flat spot worn into the hinge pin itself. The permanent fix takes just minutes and costs almost nothing.
