The Fascinating History and Versatile Applications of WD-40

WD-40 was created in 1953 by Norm Larsen. It was originally designed to prevent corrosion on nuclear missiles. The 'WD' stands for 'Water Displacement,' while '40' signifies the 40th attempt to perfect the formula.

The exact formula of WD-40 remains a trade secret, closely guarded and never patented to avoid full disclosure. However, it's primarily a mix of various hydrocarbons, including aliphatic and napthenic petroleum-based oils.

Contrary to popular belief, WD-40 isn't a true lubricant. It's more of a solvent and rust dissolver. Its lubricating properties are short-term, making it better suited for cleaning than long-term lubrication.

WD-40 has ventured into space! NASA used it to protect the outer skin of the Atlas Missile from rust and corrosion. This space-age connection rocketed WD-40's popularity among consumers in the 1960s.

Beyond rust prevention, WD-40 is used for tasks like removing chewing gum from hair, cleaning piano keys, and even repelling insects. Its versatility has made it a staple in households and workshops globally.

WD-40's popularity is staggering. The company produces over a million cans of the product every week. It's distributed in more than 176 countries and territories around the world, with the logo recognized universally.

There's a market for collectors of vintage WD-40 cans. The original design has changed very little, but collectors prize the earliest cans for their nostalgia and the history they represent in American innovation.
