History Of The Contenders

In this section, we will delve into the history of the contenders: Pb Blaster, WD-40, and Penetrating Oil. These three products have gained widespread popularity as effective solutions for loosening rusted or stuck components. Each contender comes with its own unique formulation and historical background, making it interesting to explore their origins and development.

Pb Blaster

Pb Blaster, short for “Penetrating Blaster,” was introduced in the 1950s and quickly gained a reputation for its exceptional penetrating powers. It was initially developed as a solution for loosening frozen piston rings in automotive engines. The unique blend of solvents and additives in Pb Blaster allows it to break through rust and corrosion, making it a go-to choice for many professionals and DIY enthusiasts.


Contrary to popular belief, WD-40 is not primarily a penetrating oil; it’s a multi-purpose lubricant. The name itself stands for “Water Displacement, 40th Attempt,” highlighting the product’s origin story. WD-40 was first formulated in the 1950s by a team of chemists who were working on a solution to prevent corrosion in aerospace technology. Eventually, they discovered its versatility in many other applications, making it a household name.

Penetrating Oil

The term “penetrating oil” refers to a category of products rather than a specific brand. Penetrating oils are specifically designed to infiltrate rusted or corroded parts, providing lubrication and facilitating easier removal. While various brands offer their own penetrating oil formulations, the unique blend of solvents, detergents, and corrosion inhibitors present in these products helps in freeing frozen bolts, nuts, and other components.

Ingredients Breakdown

When it comes to choosing the right penetrating oil for your needs, understanding the ingredients can make all the difference. Let’s break down the ingredients of Pb Blaster, WD-40, and Penetrating Oil to see what sets them apart.

Pb Blaster

Pb Blaster is known for its powerful formula that helps to loosen rusted parts and protect against future corrosion. Here are the key ingredients:

  • Petroleum Distillates: These are the main solvents in Pb Blaster, helping to dissolve rust and lubricate moving parts.
  • Liquefied Petroleum Gas: This ingredient works as a propellant, ensuring that Pb Blaster can reach tight spaces and penetrate deeply.
  • Non-Chlorinated Solvent: This is another solvent that aids in breaking up rust and corrosion.
  • Corrosion Inhibitors: Pb Blaster contains additives that form a protective barrier, preventing further rust and corrosion.
  • Fragrance: Lastly, a fragrance is added to mask the strong smell of petroleum distillates, making it a more pleasant experience to use.


WD-40 is a well-known multi-purpose lubricant that also has some penetrating properties. Here’s what you’ll find in a can of WD-40:

  • Aliphatic Hydrocarbons: These are the main solvents in WD-40, allowing it to dissolve rust and lubricate moving parts.
  • Mineral Oil: This ingredient provides further lubrication and helps to protect against rust and corrosion.
  • Carbon Dioxide: WD-40 contains a propellant to help disperse the product effectively.
  • Corrosion Inhibitors: Similar to Pb Blaster, WD-40 also includes additives to prevent further rust and corrosion.
  • Fragrance: A pleasant smell is added to mask the strong odor of the solvents present in WD-40.

Penetrating Oil

Penetrating oils, in general, are designed to loosen stuck parts by penetrating rust and corrosion. While specific formulations may vary, here are some common ingredients you might find in a bottle of penetrating oil:

  • Mineral Oil: This provides lubrication and helps to free stuck parts.
  • Acetone: Often included for its strong solvent properties, acetone can quickly dissolve rust and corrosion.
  • Xylene: Similar to acetone, xylene is another powerful solvent used to break up rust and corrosion.
  • Corrosion Inhibitors: Penetrating oils typically contain additives to prevent further rust and corrosion.

While each product has its own unique formulation, understanding the ingredients can help you determine which one is best suited for your specific needs. Consider the type of rust or corrosion you’re dealing with, the intended use, and any other factors that may impact your decision.

Application And Effectiveness

When it comes to penetrating oils, choosing the right product for the job can make a significant difference in the effectiveness of rust-busting, versatility, and long-term effects. Let’s explore the application and effectiveness of three popular options: PB Blaster, WD-40, and Penetrating Oil.

Rust-busting Performance

PB Blaster is renowned for its impressive rust-busting performance. Its formula is specifically designed to break through rust and corrosion, making it highly effective in loosening stubborn, rusted parts.

WD-40 also offers decent rust-busting performance, but it may require multiple applications and some soaking time to achieve similar results compared to PB Blaster.

Penetrating Oil is formulated to penetrate and free rusted or seized parts. It offers good rust-busting performance, but it may not be as potent as PB Blaster in more challenging situations.

Versatility And Applications

  • PB Blaster excels in a wide range of applications, from automotive to industrial use. Its versatility makes it a go-to choice for various maintenance and repair tasks.
  • WD-40 is known for its versatility, with applications beyond just rust penetration. It’s a multi-purpose lubricant that can be used for various tasks, from loosening stuck mechanisms to protecting metal surfaces from corrosion.
  • Penetrating Oil is suitable for general maintenance and repair work, but it may not be as versatile as WD-40 or PB Blaster in terms of applications.

Long-term Effects

  1. PB Blaster leaves behind a protective film to prevent future rust and corrosion, offering long-term protection to treated surfaces and parts.
  2. WD-40 provides some level of ongoing protection against rust and corrosion but may require more frequent reapplication to maintain long-term effects compared to PB Blaster.
  3. Penetrating Oil may offer minimal long-term protection and may necessitate more frequent reapplication to prevent rust and corrosion compared to PB Blaster and WD-40.
