What is WD-40? A Deep Dive into Its Composition and Function

WD-40 isn’t just a lubricant; it’s a complex blend of various ingredients designed to perform a specific set of functions. The name itself provides a clue: “WD” stands for “Water Displacement,” and “40” refers to the fortieth formula the company used to achieve its desired effect. Originally developed in 1953 by the Rocket Chemical Company (later renamed WD-40 Company), it was intended to prevent corrosion on missiles. Its effectiveness quickly led to its adoption for commercial use.

The exact formula of WD-40 is a closely guarded secret, but its primary components are known to include:

Mineral Oil: Acts as a lubricant, reducing friction between moving parts.
Aliphatic Hydrocarbons: These volatile organic compounds (VOCs) contribute to WD-40’s penetrating ability and help to dissolve grease and grime.
Carbon Dioxide: Used as a propellant to dispense the product.

It’s important to understand that WD-40 is not a long-term lubricant. While it effectively displaces water and loosens rust, its lubricating properties are relatively short-lived. For long-term lubrication, a dedicated lubricant is recommended.

Understanding WD-40’s Multifaceted Action

WD-40’s effectiveness stems from its ability to perform several key actions simultaneously:

Water Displacement: As its name suggests, WD-40 effectively displaces water, preventing corrosion and electrical shorts.
Penetration: Its low viscosity allows it to penetrate tight spaces, loosening rust and corrosion.
Lubrication: While not a long-term lubricant, it provides temporary lubrication to reduce friction.
Cleaning: It dissolves grease, grime, and other sticky residues.
Corrosion Protection: It forms a thin barrier that protects metal surfaces from moisture and corrosion.

The WD-40 Product Line: Beyond the Original Formula
