What happened next is what turned WD-40 into a global household essential. Once the Rocket Chemical Company realized how effective the formula was, they began producing it beyond military use. Workers started bringing it home. Friends borrowed it. Word spread fast. People discovered it could loosen rusted tools, silence squeaky hinges, protect metal from moisture, clean grime, and free stuck mechanisms with almost no effort.
The product’s versatility became its legend. Mechanics used it on engines. Cyclists used it on chains. Homeowners sprayed it on door hinges, lawn equipment, grills, locks, and garden tools. It even found uses outside metalwork, from removing sticky residue to loosening jammed zippers. Over time, WD-40 became shorthand for “the thing that fixes it.”
As the product grew, so did the company behind it. The Rocket Chemical Company eventually rebranded, becoming the WD-40 Company. The name reflected what the world already knew: this single formula had outgrown its military origins and become a cornerstone of everyday maintenance across industries and households.
What makes WD-40 especially compelling isn’t just what it does, but how it came to exist. The story is built on failure—thirty-nine of them, to be exact. In a culture obsessed with overnight success, WD-40 stands as a quiet counterexample. Its creation was not a stroke of genius followed by instant reward. It was methodical, repetitive experimentation carried out until the solution finally worked.
