The Silent Click: Eliminating the Stuck Gas Cap Door

My car's fuel door latch was sticking—it was stiff, slow to open, and sometimes required three or four presses of the release button. It was a minor annoyance that was quickly becoming a major hassle! I applied WD-40 Multi-Use Product directly to the latch mechanism and hinge. The results were instant: the door now opens immediately with a smooth, silent click. This spray saved me from a trip to the mechanic and restored the smooth functionality of my car.

Confirm the latch and hinge are stiff due to a lack of lubrication, not a mechanical break.

Using the Smart Straw, spray a short burst of WD-40 Multi-Use Product directly onto the latch pin and the hinge pivot point inside the fuel door area.

Open and close the fuel door several times to allow the lubricant to fully penetrate the mechanism. Enjoy the silent and smooth function.
