This blog post delves into the underlying causes of rust on cast iron skillets and provides comprehensive guidance on preventing and removing this unwelcome invader.
Understanding the Nature of Rust
Rust, or iron oxide, is a reddish-brown compound that forms when iron comes into contact with oxygen and moisture. In the case of cast iron skillets, the iron in the skillet reacts with these elements to create rust.
Causes of Rust on Cast Iron Skillets
1. Improper Seasoning
Seasoning is a crucial step in protecting cast iron skillets from rust. Seasoning involves coating the skillet with a layer of oil or fat that creates a barrier between the iron and the elements. Without proper seasoning, the skillet is vulnerable to moisture and oxygen, which can lead to rust.
2. Inadequate Drying
After washing or rinsing a cast iron skillet, it is essential to dry it thoroughly to prevent moisture from lingering on the surface. Even small amounts of moisture can provide an opportunity for rust to develop.
3. Storage in Humid Environments
Storing a cast iron skillet in a humid environment, such as a basement or near a dishwasher, exposes it to excessive moisture that can accelerate the rusting process.
4. Chemical Reactions with Food
Certain foods, such as acidic sauces or vinegar, can react with the iron in the skillet and cause rust to form.
5. Use of Abrasive Cleaners
Harsh abrasive cleaners can strip away the seasoning on a cast iron skillet, making it more susceptible to rust.
How to Prevent Rust on Cast Iron Skillets
1. Season Regularly
Seasoning is the key to preventing rust on cast iron skillets. Seasoning creates a protective layer that shields the iron from moisture and oxygen.
2. Dry Thoroughly
After washing or rinsing a cast iron skillet, use a clean towel to dry it thoroughly. Leaving any moisture on the surface can provide an opportunity for rust to develop.
3. Store in a Dry Place
Store your cast iron skillet in a dry, well-ventilated area. Avoid storing it in humid environments or near sources of moisture.
4. Avoid Acidic Foods
When cooking with acidic foods, use a non-reactive cooking utensil to prevent the acid from reacting with the iron in the skillet.
5. Use Gentle Cleaners
When cleaning a cast iron skillet, use gentle cleaners such as mild dish soap and warm water. Avoid using abrasive cleaners or harsh chemicals.
How to Remove Rust from Cast Iron Skillets
1. Scrub with Coarse Salt
Sprinkle coarse salt on the rusted area and scrub it with a damp cloth or sponge. The salt will act as an abrasive and help remove the rust.
2. Use a Rust Remover
Apply a commercial rust remover to the rusted area and follow the instructions on the product label. Rust removers are effective in removing rust but can be harsh, so use them with caution.
3. Use a Steel Wool
Gently rub the rusted area with fine-grit steel wool. Be careful not to use too much pressure, as this can damage the seasoning on the skillet.
Tips for Maintaining Cast Iron Skillets

Seasoning is the cornerstone of cast iron skillet maintenance. Season your skillet regularly to keep it protected from rust.
2. Dry Thoroughly
Always dry your cast iron skillet thoroughly after washing or rinsing it.

Avoid using extremely high heat on a cast iron skillet. High heat can damage the seasoning and make the skillet more susceptible to rust.
4. Store Properly
Store your cast iron skillet in a dry, well-ventilated area. Avoid storing it in humid environments or near sources of moisture.
