## A Deep Dive into WD-40
WD-40 isn’t just a product; it’s a cultural icon. But beyond the familiar blue and yellow can lies a fascinating story and a versatile formula.
### What is WD-40?
WD-40 stands for “Water Displacement, 40th formula.” It was developed in 1953 by Norman Larsen, who was part of the Rocket Chemical Company. The goal was to create a rust preventative and water displacement solution for the aerospace industry, specifically to protect the Atlas missile from corrosion. The 40th attempt was the successful formula, hence the name.
While the exact formula remains a closely guarded secret, WD-40 is primarily composed of various hydrocarbons. It acts as a lubricant, penetrating oil, rust preventative, and cleaning solvent. Its low viscosity allows it to seep into tight spaces, displacing moisture and breaking down rust and grime.
