What Exactly *Is* WD-40? A Deep Dive

WD-40, short for “Water Displacement, 40th formula,” was originally developed in 1953 by the Rocket Chemical Company (now WD-40 Company). Its primary purpose was to prevent corrosion by displacing water. The exact formula is a closely guarded secret, but we know it’s a petroleum-based solvent with a blend of various ingredients, including mineral spirits and carbon dioxide. This unique composition gives WD-40 its characteristic properties, but it also leads to the common misconception about its primary function.

The Core Components of WD-40 and Their Roles

* **Mineral Spirits:** Act as a solvent and help to dissolve grease, grime, and other contaminants.
* **Petroleum-Based Oil:** Provides a thin film of lubrication, but it’s not the primary function.
* **Carbon Dioxide:** Used as a propellant to dispense the liquid.
* **Proprietary Ingredients:** These enhance WD-40’s water displacement and corrosion protection capabilities.

Dispelling the Myths: WD-40 as a Lubricant

While WD-40 *does* provide some lubrication, it’s important to understand that it’s not a *long-term* lubricant. The thin film of oil it leaves behind is often insufficient for high-friction applications or situations requiring lasting lubrication. Think of it as a temporary fix rather than a permanent solution for lubrication needs. Its light viscosity means it can easily be displaced or evaporate over time, leaving surfaces vulnerable to wear and tear. Many users have learned this the hard way, experiencing a temporary improvement followed by a return of the problem, sometimes even worse than before.

WD-40 as a Degreaser: Its Solvent Properties

WD-40’s effectiveness as a degreaser stems from its solvent properties. The mineral spirits in its formula dissolve grease, oil, and grime, making it useful for cleaning dirty surfaces. It can break down sticky residues, loosen rust, and remove adhesives. However, just like with its lubricating properties, it’s crucial to understand its limitations as a degreaser.

How WD-40 Degreases: A Chemical Explanation

WD-40 works as a degreaser by reducing the surface tension of the grease and oil, allowing it to be easily wiped away. The solvents penetrate the grime, breaking it down into smaller particles that can be dissolved and removed. This makes it effective for cleaning tools, removing sticker residue, and loosening stuck parts. However, it’s not as powerful as dedicated degreasers, which often contain stronger solvents and detergents.

The Limitations of WD-40 as a Degreaser

While WD-40 can remove light grease and grime, it’s not ideal for heavy-duty degreasing tasks. It may not completely remove thick, stubborn grease buildup, and it can leave behind a thin oily residue that can attract more dirt and grime. For demanding degreasing applications, it’s best to use a specialized degreaser that is specifically formulated for the task.
