Is GT85 the Same as WD40? 

GT85 and WD-40 are both popular multi-purpose lubricants and rust inhibitors. WD-40, an established brand, was originally developed for industrial use with a focus on preventing corrosion and providing lubrication. Its name signifies its 40th attempt to create the formula. GT85, on the other hand, is a specific brand commonly used in cycling and motorcycle maintenance. 

While both products share similarities in general uses, such as loosening stuck parts and preventing rust, their formulations may vary, with GT85 often optimized for specific tasks related to bike maintenance. It’s important to read the product labels for specific instructions and applications to ensure effective use.

How did WD-40 originate and what makes it versatile for industrial use?

How did WD-40 originate and what makes it versatile for industrial use

WD-40 is a widely used multi-purpose penetrating oil and water-displacing spray. Its name stands for “Water Displacement, 40th formula.” The product was created in 1953 by a small company called Rocket Chemical Company, founded by Norm Larsen in San Diego, California. The formula was developed to create a rust-prevention solvent and degreaser for use in the aerospace industry.

The story goes that the chemists at Rocket Chemical Company were attempting to create a formula to prevent corrosion on rockets and missile parts. After 39 failed attempts, they finally arrived at the successful formula on the 40th try. This formula had a variety of uses beyond its original intended purpose, leading to the creation of WD-40.

The versatility of WD-40 for industrial use can be attributed to several key properties:

Water Displacement

WD-40 has excellent water-displacing properties, making it effective in protecting metal surfaces from moisture and preventing corrosion. This quality is crucial in various industrial applications where machinery and equipment are exposed to the elements.

Penetrating Oil

WD-40 acts as a penetrating oil, which means it can loosen rusted or stuck parts. This makes it useful for maintenance tasks where it’s necessary to free up seized bolts, nuts, and other components.


WD-40 can be used as a lubricant to reduce friction between moving parts. It’s effective in this regard for light-duty applications, though for heavier loads or extreme conditions, specialized lubricants may be more suitable.

Cleaning and Degreasing

WD-40 is a good cleaner and degreaser, helping to remove grime, grease, and other contaminants from surfaces. This makes it useful for general maintenance and cleanup tasks in industrial settings.

Protective Coating

The product leaves behind a protective film on surfaces, which helps to inhibit rust and corrosion. This makes it suitable for preventing damage to metal surfaces over time.

What distinguishes GT85 as a brand?

GT85 is a brand of multi-purpose spray lubricants and cleaners. However, specific details about the brand’s features or any updates in its offerings may have changed since then. Here are some general characteristics that are often associated with GT85:
