What is WD-40 Penetrating Oil and How Does It Work?

WD-40 Penetrating Oil is a specialized formulation designed to loosen rusted and corroded parts. Unlike the original WD-40 Multi-Use Product, which primarily acts as a water displacement and lubricant, the penetrating oil is engineered to seep into tight spaces and break down rust and corrosion. This allows for easier disassembly and prevents damage to components.

The Science Behind Penetration

The effectiveness of WD-40 Penetrating Oil lies in its unique blend of solvents, lubricants, and corrosion inhibitors. These components work synergistically to:

• Reduce Surface Tension: The penetrating oil has a low surface tension, allowing it to easily flow into small crevices and between tightly fitted parts.
• Dissolve Rust and Corrosion: Solvents in the formula dissolve rust and corrosion, breaking down the bonds that hold the parts together.
• Lubricate: Lubricants reduce friction, enabling parts to move more freely once the rust and corrosion are dissolved.
• Inhibit Further Corrosion: Corrosion inhibitors create a protective barrier, preventing further rust and corrosion from forming.

The key is the specialized solvents that have a higher capillary action than standard lubricants, enabling them to wick into incredibly tight spaces. This targeted action is what sets it apart from general-purpose lubricants.
