What is Rusting?

The interaction between iron and oxygen is crucial to understanding the actual physical and chemical reactions that are taking place. As iron oxidizes, Iron Oxide is generated.

Why Does a Grill Rust?

Many people believe that stainless steel grills are rust-proof, regardless of the type of grill. Chromium is used in stainless steel to prevent it from staining. However, if there is a gap between the surface and the chromium, grill rust can occur. Interaction with other rust-bearing metals causes the stainless steel to tarnish.

When iron transfers from another metal to stainless steel and combines with water and oxygen, rust is formed. Due to the undesirable visual appearance that results, this is usually the most troublesome of all. In spite of the fact that rust on stainless steel is largely controlled by the inner chrome, it is nevertheless an unwelcome nuisance to have rust develop on it.
