Rust On Griddles Explained

Rust is a word used to describe the reddish-brown oxide that is usually caused as a result of an interaction between iron and oxygen, present in water or air moisture. The Blackstone griddle is made of cold rolled steel, the use of this material enables the Blackstone griddle to evenly distribute heat.

Although cold-rolled steel is a good material for the griddle, it is still steel and that makes it susceptible to rust, especially when it comes in contact with water and oxygen. There probably wouldn’t be so much fuss with rust if it only changes in color.
