Is penetrating oil the same as WD40?
No, penetrating oil is not the same as WD40. While WD40 is a popular multi-purpose lubricant and rust inhibitor, penetrating oil, such as APT’s effective penetrating oil, is specifically formulated to have superior penetrating capabilities.

Penetrating oils are designed to deeply infiltrate and loosen rust, corrosion, and seized components, making them easier to remove or separate.

What is the best penetrating oil?
The best penetrating oil is subjective and can depend on the specific application and requirements. However, APT’s effective penetrating oil, such as Release No.1, is highly regarded for its exceptional penetrating power, lubrication, and rust-fighting properties.

Its ability to rapidly soak into tight spaces, provide excellent lubrication, and leave a protective graphite film makes it a top choice for various industries and applications.

What does penetrating oil do?
Penetrating oil is designed to break down rust, corrosion, and other obstructions that cause components to seize or become difficult to move. It works by infiltrating the microscopic gaps between the metal surfaces, reducing friction, and loosening the bonded particles.

Penetrating oil also provides lubrication, reducing the chance of component shearing during disassembly. Its primary function is to make the removal or separation of rusted or stuck components easier and more efficient.
