The amazing WD-40, who knew that something that keeps your wheels and hinges from squeaking was such a benefit to so many things. Until I did research for this article, I was one of those people.
If you have ever had a squeaky door hinge, a stubborn bolt, or a rusty tool, chances are someone told you, “Just grab the WD-40.” And for good reason. This little blue-and-yellow can has been a household hero since 1953, when it was first developed to protect missiles from rust and corrosion (yes, really). It was developed by three technicians at the San Diego Rocket Chemical Company. Ken East, one of the original founders made note that there is nothing in WD-40 that will hurt you. After the 40th version of the formula was successful, the Corvair Company bought it in bulk to protect their atlas missile parts.
The “WD” stands for Water Displacement, and the “40” means it was the 40th attempt before the team got it right. Persistence paid off, because decades later, WD-40 is still going strong. WD-40 is truly a household hero and a game changer. If you think it is just for squeaky hinges, think again.
Today, it is far more than a rust preventer. WD-40 has become the Swiss Army knife of sprays, solving problems in homes, garages, offices, and even gardens around the world. While most people know the basics, i.e. stop a squeak, loosen a stuck bolt, this can of magic has hundreds of creative, practical, and even surprising uses.
Let’s dive into the amazing world of WD-40 and explore why it deserves a spot in every home and toolbox.
