How to Select the Rust Preventive Oil

Rust preventive oil, also known as rust inhibitor or corrosion inhibitor oil, is a type of lubricant designed to protect metal surfaces from rust and corrosion. It forms a thin protective film on the metal, preventing moisture and oxygen from coming into contact with the surface.

Rust preventive oils are commonly used in protecting metal surfaces and machine parts before, during and after machining as well as during storage at factory. As we know, rust forms on metal parts when it comes in contact with water or oxygen. Then, it can quickly become a big problem which results in equipment failure, increased power consumption, non-salable parts and other problems in the industry.
