Fun fact, while WD-40 can act as a solvent, but its original purpose is to repel water "water displacement" and the 40th attempt in their formulation efforts. It just so happens to be otherwise useful, but it is NOT a lubricant.

    For maybe an hour of use at most. It's not good at being a lubricant at all. Which is why you use oil or grease.

    Well I can tell you that the door hinges that made a squeaking noise do not anymore for several months now after using wd40 on them.

    Another nerd - it's because the solvent in WD-40 cleared out the dirt that was causing the squeak. But you should hit the hinges with some lubricant if you'd like a longer-lasting squeak-free house.

    This nerd is right, and ive worked as a handyman for too long before i knew this and didnt have to go back to some people for squeaking doors because i started doing wd40 first and then lube it with grease.
