The Origin of WD-40
If you’ve ever needed to loosen a rusted bolt, lubricate a squeaky door hinge, or remove gum from your shoe, you’ve likely turned to a trusty can of WD-40. This ubiquitous spray has been a household staple for generations, but few people know the origin story of this miracle lubricant.
WD-40 was invented in 1953 by a small San Diego-based company called Rocket Chemical Company. The company’s founders, Norm Larsen and John Gregory, were working on a project for the U.S. government to develop a rust-prevention solvent and degreaser for the aerospace industry. After 40 attempts, they finally hit upon the winning formula, which they named WD-40 (short for “Water Displacement, 40th formula”).
What Was WD-40 Originally Invented For?
Despite its association with household chores and DIY projects, WD-40 was originally created for industrial use. The product was designed to protect metal parts from rust and corrosion, as well as to remove grease and grime from machinery. In the early days, the product was primarily used by the aerospace industry to protect missile parts from rust and corrosion.
Over time, however, the potential uses for WD-40 became apparent. The company began marketing the product to consumers as a multi-purpose lubricant, and it quickly became a household name. Today, WD-40 is used for everything from lubricating bike chains to removing sticker residue from windows.
How Does WD-40 Work?
At its core, WD-40 is a combination of various chemicals that work together to provide its signature lubricating and rust-prevention properties. The main active ingredient in WD-40 is a solvent called aliphatic hydrocarbons, which helps to dissolve grease and grime on metal surfaces.
In addition to the solvent, WD-40 also contains a variety of other ingredients, including mineral oil, silicone, and lanolin. These ingredients work together to lubricate metal parts and protect them from rust and corrosion.
What Are Some Surprising Uses for WD-40?
While most people are familiar with the standard uses for WD-40 (such as lubricating door hinges and removing rust from tools), there are actually a wide variety of other uses for this versatile spray. Here are just a few examples:
- Removing chewing gum from hair and clothing
- Loosening stuck zipper
- Removing crayon marks from walls
- Cleaning piano keys
- Removing scuff marks from floors
- Preventing snow from sticking to shovels and snowblowers
The list of potential uses for WD-40 is virtually endless, making it a must-have item in any household or workshop. Whether you’re a DIY enthusiast, a mechanic, or just someone who wants to keep their home in tip-top shape, WD-40 is sure to come in handy.
