People also ask to know

Why is my Blackstone griddle rusting?

Rust is a metal-eating process that starts with iron and other metal oxides being deposited on the surface of the metal. Over time, the metal surface becomes covered in rust, which can then be accelerated by moisture and humidity.

High acidity in foods can also contribute to rusting due to the interaction of the iron with acids in the food. This can happen when acidic foods are cooked on an older griddle that is corroded from corrosion of the metal itself. The high acidity of the food also speeds up the rusting process.

Lastly, steaming foods directly on the griddle surface can also cause rust on the surface of the griddle. This is because the moisture produced during cooking bubbles up and forms little rusts on the surface of the griddle.
