Restoring a Rusty Water Tap with WD-40

My water tap had become stiff and hard to turn due to rust and mineral deposits. I used WD-40 to spray around the base and handle of the tap. Within minutes, the tap loosened up and started turning smoothly again. The lubricant not only freed the stuck mechanism but also protected it from further rust and corrosion. This simple use of WD-40 restored my old tap and saved me from replacing it with a new one.
