What causes rust to form on cast iron griddles?
Rust forms on cast iron griddles primarily when moisture comes into contact with the iron surface. This can occur due to improper storage, such as leaving the griddle outside or in a damp area. When moisture combines with oxygen in the air, it reacts with the iron to create iron oxide, commonly known as rust. Additionally, using soap or abrasive scrubbing tools can strip away the protective seasoning layer, making the iron vulnerable to rusting.
Improper cleaning techniques can also contribute to rust formation. For instance, soaking your cast iron griddle in water for extended periods can lead to rust, as can neglecting to dry it thoroughly after washing. Ensuring you maintain your griddle’s seasoning and storing it in a dry environment are key steps to prevent rust from developing in the first place.
