Almost everyone thinks WD-40 is a lubricant, but in reality, it wasn't invented for that. And that's because WD-40 stands for water displacement, and it took 40 attempts to create its formula.

Originally, it was designed to protect metal from moisture and prevent it from rusting, which is why it also works on rusty screws and squeaky hinges. But here's the part that most people don't know, WD-40 is not designed to be a long-lasting lubricant since it evaporates over time, which is why mechanics usually apply a suitable grease or oil afterward.
