Yes, spraying a light petroleum-based lubricant like WD-40 onto creaking door hinges can temporarily eliminate squeaks and silence annoying noises by penetrating tight metal pins. However, WD-40 is primarily a water-displacing solvent rather than a long-term grease lubricant; it will eventually evaporate or wash away, requiring reapplication. Furthermore, you should never spray WD-40 or light oils onto dryer door latches where excess liquid can attract lint dust. You can troubleshoot hinge friction easily. You can verify that your corrective action is successful when applying a few drops of light oil or specialized white lithium grease to the door hinge pins stops the creaking sound instantly and ensures smooth swinging movement.
