Understanding the Basics of Rust

Rust, scientifically known as iron oxide, is the result of a chemical reaction between iron, oxygen, and moisture. This trifecta creates a corrosive environment, leading to the reddish-brown substance we recognize as rust. The implications of rust go beyond aesthetics; it weakens structures, compromises tools, and poses a threat to the longevity of our possessions.

The Science Behind Fluid Film
