how do you clean a cast iron grill press
Cast iron grill presses are essential tools every grill master needs to have. They help cook food evenly by removing excess fat, prevent food from curling, and retain heat for the perfect sear. But like any other cooking tool, grill presses need cleaning after use. Ignoring this crucial step can render your grill press useless, making it challenging to cook great food.
This comprehensive guide shows you how to clean a cast iron grill press safely and maintain it for longevity. Follow these steps, adhere to precautions and best practices for optimal results.

Tools and Materials Needed

The first step in cleaning your cast iron grill press is identifying the right tools and materials needed:
  • A soft brush
  • Paper towels or a clean cloth
  • Cooking oil
  • Mild dish soap
The soft brush removes residual debris from the surface without scratching on it. Paper towels are excellent for drying the surface while cooking oil coats prevent rusting. Using mild dish soap avoids damaging the seasoning layer on the surface of the grill press.

Steps to Follow When Cleaning Your Cast Iron Grill Press

Here are six steps to follow during cleaning:

1. Allow the Grill Press to Cool Down

When finished cooking, give your grill press time to cool down slightly before starting the cleaning process.

2. Use a Soft Brush to Remove Any Food Residue or Debris.

Gently scrub away any stuck-on bits with a soft brush. Take your time as rushing can cause damage or scratches on the surface.

3. Rinse the Grill Press with Warm Water

Rinse away all traces of debris using warm water and avoid cold water as it can cause thermal shock to the hot surface and damage the grill press.

4. Dry off the Grill Press Using Paper Towels or a Cloth

Immediately dry the grill press using paper towels or a clean cloth. Any moisture left on the surface will cause rust, necessitating re-seasoning of your grill press.

5. Apply a Small Amount of Cooking Oil to the Surface

Apply a small amount of cooking oil to all sides of the grill press surface with a paper towel. This method protects against rust build-up and helps to retain natural seasoning.

6. Store Away in a Dry Place

When done with cleaning, keep the grill press away from moisture and acids like vinegar and tomato sauce that can cause rust formation. An excellent place to store it is in a dry room where there is less humidity.

Tips for Maintaining Your Cast Iron Grill Press

Maintaining your cast iron grill press ensures its longevity and effectiveness in cooking delicious food. These tips will help prolong the life of your grill press:
  • Season after every use by applying a thin layer of oil over all surfaces of the grill press
  • Protect against moisture by storing it in a dry location
  • Clean regularly after each use: build-ups of grease or acid can be harmful to the seasoning layer of your grill plate.

How Often Should You Clean Your Cast Iron Grill Press?

Frequency of cleaning your cast iron grill press depends on usage, food type, and how often you cook using it. An average user would clean it after every use. However, if you are not an avid user, clean it every three months to prevent rust from building up.

Best Practices for Routine Care and Maintenance

To maintain optimal quality between uses of your cast iron grill press, follow these best practices:
  • Always preheat before use
  • Clean promptly after each use: don’t leave the grime on the surface overnight
  • Don’t overheat as it can damage the seasoning layer.
  • Season regularly with oil to strengthen nonstick performance
  • Avoid using harsh abrasive cleaners like metal scouring pads or steel wool that can damage the surface

Restoring Older or Rusty Cast Iron Grill Presses

Cleaning Rusted Cast Iron Grill Press

If you have an old or rusted cast iron grill press, don’t give up on it; it only takes a few simple steps to heal the rust off and restore its natural strength.

Options for Removing Rust

  • Scrubbing with vinegar and salt: Mix one cup of vinegar with ¼ cup of sea salt in a large container. Soak your grill press in the solution for a few hours followed by scrubbing using a soft brush.
  • Using Steel Wool and Baking Soda:Sprinkle baking soda on a damp surface before brushing off with steel wool and rinse thoroughly.

Steps to Heal Your Cast Iron Grill Press After Rust Removal

Once rust is removed, you need to season your grill press once again to maintain its non-stick surface. Follow these steps:
  1. Rub oil (canola, flaxseed, vegetable oil) onto your grill press, ensuring the entire surface is covered. To prevent oil from pooling in one area, remove excess with a paper towel.
  2. Place it in the oven preheated to 450°F for an hour to harden the oil on the surface. You can place foil beneath it to catch drips and avoid spills.
  3. Leave in the oven until it cools before storing it away.

Avoiding Common Mistakes When Cleaning Your Cast Iron Grill Press

To avoid damaging your grill press during cleaning, here are four common mistakes to steer clear of:
  1. Over-using soap while washing: Mild dish soap is essential but avoid overusing as it breaks down the seasoning layer.
  2. Forgetting to preheat before the next use: Preheating helps emit excess fluid and prevents hot spots on the cooking surface.
  3. Not completely drying before storage: Leaving moisture on the surface causes rusting.
  4. Leaving acidic food like tomato sauce, citric fruits on the surface overnight: The acid strips out seasoning layers hence causing rust or metallic taste in your cuisine.


Cleaning and maintaining your cast iron grill press adds longevity and quality to your grilling experience. Follow the outlined precautions, tools, and step-by-step process for optimal results. Regularly caring for your grill plate reduces wear and increases non-stick performance- a must-have for every grilling enthusiast.
