## Understanding Rust: The Science Behind the Problem
Rust, or iron oxide, is the result of an electrochemical reaction between iron, oxygen, and water (or moisture). This process, known as oxidation, weakens the metal and creates the characteristic reddish-brown flaky substance we call rust. Understanding this process is key to effectively preventing and removing rust from your bike chain.
The presence of electrolytes, such as salt, acids, or other contaminants, accelerates the rusting process. This is why bikes ridden in coastal areas or during winter (where salt is used on roads) are particularly susceptible to rust.
