Cast iron cookware is cherished for its exceptional heat retention and even cooking. Among these beloved pieces, the cast iron griddle is a versatile kitchen tool that can make any cooking experience more enjoyable. However, improper maintenance or prolonged periods without use can lead to rust forming on its surface. Fear not! This article will guide you through effective techniques to clean a rusted cast iron griddle, restoring its beauty and functionality.
Why Does Cast Iron Rust?
Before diving into the cleaning process, it’s essential to understand why cast iron rusts. Several factors can contribute to rusting:
- Moisture: Exposure to water or humidity can initiate rust formation.
- Neglected Seasoning: The seasoning layer, a protective coating of oil baked into the cast iron, wears away over time, making it vulnerable to rust.
Recognizing these causes helps prevent future rusting, ensuring your griddle remains a cherished kitchen companion.
Essential Supplies for Cleaning Your Cast Iron Griddle
Before you start the cleaning process, gather the necessary supplies. Here’s what you’ll need:
- Fine steel wool or a gentle scrub pad
- Cast iron-safe scrubber or brush
- Vegetable oil or seasoning oil
- Paper towels or a clean rag
- Dish soap (optional)
- White vinegar (optional)
These items will empower you to tackle rust and restore the integrity of your cast iron griddle.
The Step-by-Step Process to Clean a Rusted Cast Iron Griddle
Cleaning a rusted cast iron griddle requires patience, but the results are worth the effort. Follow these steps:
Step 1: Assess the Level of Rust
Before starting the cleaning process, examine your griddle to determine the extent of the rust. Light rust can often be removed with a bit of scrubbing, while heavy rust may require more intensive treatment.
Step 2: Remove Loose Rust and Debris
Using a fine steel wool or a cast iron-safe scrubber, gently scrub the rusted areas of your griddle. For moderate rust, this should be sufficient to remove the loose particles. For heavy rust, you might need to apply more pressure.
Step 3: Deep Clean with Dish Soap and Water (Optional)
Although many cast iron purists avoid soap, using a small amount of mild dish soap mixed with warm water can help remove built-up grime and grease. Use a scrub brush to clean the surface, then rinse thoroughly with warm water.
Note: If your griddle is heavily rusted, you might consider dipping it in a solution of equal parts white vinegar and water for about 30 minutes before scrubbing. Vinegar is acidic and can help dissolve rust, making it easier to scrub away.
Step 4: Rinse and Dry Thoroughly
After scrubbing, rinse your griddle under warm running water to eliminate all soap residues and rust particles. It’s crucial to dry it thoroughly right after washing to prevent new rust from forming. You can place it on a low burner on your stovetop for a few minutes to ensure all moisture evaporates.
Step 5: Season Your Cast Iron Griddle
Once your griddle is clean and dry, it’s time to re-season it. Proper seasoning creates a non-stick surface and helps prevent future rust. Here’s how to do it:
How to Season Your Cast Iron Griddle
- Preheat your oven to 375°F (190°C).
- Apply a thin layer of vegetable oil or seasoning oil over the entire surface of your griddle, including the handle and underside.
- Place a sheet of aluminum foil on the bottom rack of your oven to catch any drips.
- Place your griddle upside-down on the middle rack.
- Bake for one hour, then turn off the oven and let the griddle cool inside.
This process will create a durable, long-lasting seasoning that protects against rust.
Preventing Future Rust on Your Cast Iron Griddle
After successfully cleaning and seasoning your griddle, you want to ensure it stays rust-free for years to come. Here are some preventive measures:
Regular Cleaning and Seasoning
Make it a habit to clean your griddle after each use. Use minimal soap and avoid soaking it in water. After cleaning, always dry it thoroughly and apply a thin layer of oil before storing.
Avoid Cooking Acidic Foods
Cooking high-acid foods like tomatoes, citrus, or vinegar-based sauces can strip away the seasoning layer. If you do cook these items, re-season your griddle afterward to maintain its integrity.
Store Properly
Store your cast iron griddle in a dry environment. If stacking cookware, place a paper towel between pieces to absorb moisture.

What is a cast iron griddle?
A cast iron griddle is a flat cooking surface made from cast iron, known for its exceptional heat retention and distribution. It typically has a smooth surface and raised edges, making it ideal for various cooking methods, including frying, baking, and grilling. Cast iron griddles can be used on the stovetop or in the oven, and they develop a naturally non-stick surface when seasoned correctly.
Cast iron cookware has been beloved for generations, prized for its durability and ability to enhance the flavors of the food cooked in it. When properly cared for, cast iron griddles can last a lifetime, making them a worthwhile investment for any kitchen.
What causes rust on a cast iron griddle?
Rust on a cast iron griddle is primarily caused by exposure to moisture and air. When the protective seasoning layer of oil gets damaged or worn away, the bare cast iron is exposed to oxygen and humidity, leading to oxidation, or rust formation. This can occur if the griddle is left wet after cleaning or stored improperly without adequate drying.
In addition, cast iron can rust if it is placed in a dishwasher or soaked in water for an extended period. Even if the griddle is dried afterwards, the prolonged exposure can cause rust if left unattended. Regular seasoning and proper storage help prevent rusting and maintain the griddle’s longevity.
How do I clean a rusted cast iron griddle?
To clean a rusted cast iron griddle, begin by removing any loose rust with a wire brush or steel wool. This will help restore the surface to its original texture. After scrubbing off the rust, wash the griddle with warm water and a mild detergent, which is generally acceptable for heavily rusted pieces, although it should be avoided for regular maintenance to preserve seasoning.
Once cleaned, thoroughly dry the griddle with a cloth or paper towel to prevent new rust from forming. Heat the griddle on the stove or in the oven for a few minutes to ensure all moisture evaporates. Afterward, apply a thin layer of vegetable oil or a specific cast iron seasoning product, and bake it at a high temperature for an hour to reestablish the seasoning.
Can I use soap on my cast iron griddle?
Using soap on a cast iron griddle is generally discouraged during routine cleaning because it can strip away the seasoning that protects the cast iron. However, if the griddle is extensively rusted or heavily soiled, a small amount of mild dish soap can be used sparingly to help clean the surface. It’s essential to rinse thoroughly afterward and ensure the griddle is dried completely.
For regular maintenance, a simple cleaning method using hot water and a stiff brush typically suffices. After cleaning, it’s a good idea to season the griddle again to maintain its non-stick surface and prevent rust development in the future.
How often should I season my cast iron griddle?
The frequency with which you should season your cast iron griddle depends on how often you use it and the types of foods you cook. A good rule of thumb is to season it after every few uses, especially if you notice food sticking or if there are signs of wear on the seasoning layer. For griddles that see heavy use or are used for frying, more frequent seasoning might be necessary.
During routine use, if food continues to slide off easily without sticking, and if the surface has a shiny appearance, it may not need immediate re-seasoning. Regular maintenance with oil and careful cleaning can prolong the life of the seasoning, but keeping an eye on the surface is key to ensuring it remains functional.
What oil is best for seasoning cast iron?
When seasoning cast iron, the best oils to use are those with high smoke points, such as flaxseed oil, grapeseed oil, or canola oil. Flaxseed oil is particularly favored for its ability to create a hard, durable layer when heated, yielding a smooth surface. Canola and grapeseed oils are also good options as they are neutral-flavored and relatively inexpensive.
It’s essential to apply a thin layer of oil to the griddle’s surface before baking it in the oven. Too much oil can lead to a sticky surface, while the right amount will result in a perfectly seasoned griddle. Always allow the oil to reach its smoke point to ensure effective polymerization, creating a resilient non-stick coating.
Is it safe to use a rusted cast iron griddle?
Using a rusted cast iron griddle is generally not advisable, as surface rust can potentially flake off into food. While ingesting small amounts of rust is not likely to cause serious harm, it can create an unpleasant texture and taste. It is best to remove any rust before using the griddle again to ensure you are cooking on a safe and clean surface.
If you encounter a heavily rusted piece, it’s wise to thoroughly clean or restore it before cooking. The restoration process typically removes rust and re-establishes the protective seasoning, making the griddle safe and ready for use.
Can I store my cast iron griddle in the oven?
Storing your cast iron griddle in the oven is generally an acceptable practice as long as the oven is not used for cooking when the griddle is inside. This method ensures that it is kept away from moisture and dirt that can lead to rusting. Before storing, ensure that the griddle is well-seasoned and completely dry to minimize the risk of rust developing.
However, if you frequently use your oven, it’s advisable to find a dedicated storage spot that does not interfere with your cooking routines. Regardless of where you store it, ensure that the griddle is protected from moisture and temperature changes to maintain its seasoning and overall condition.
