How to Clean a Cast Iron Grill Press

Cooking on a cast iron grill is an absolute delight, as it can help you achieve that perfect crust and sear on your food. But with frequent use, the grill can get dirty and greasy, making it difficult to cook on and potentially harming the flavor of your food. That’s where a cast iron grill press comes in handy. Not only does it help cook your food evenly, but it also helps remove excess grease from the surface of your grill. However, just like any other cooking tool, they too require regular cleaning to maintain their efficacy and longevity.

Importance of Keeping Them Clean

For starters, keeping your cast iron grill press clean ensures that it retains its non-stick properties. As moisture can be a winter enemy of cast-iron appliances, leaving your cast iron grill press wet and dirty may cause rust to accumulate, thus shortening its lifespan. Cleaning the device regularly also keeps it sanitary and free from unwanted bacteria buildup.

Overview of the Cleaning Process

Before rolling up your sleeves and starting to clean your cast iron grill press, there are some things you need to keep in mind. Firstly, abrupt temperature changes will drastically shorten the life of any iron appliance; therefore, avoid trying to wash a hot grill press. Always leave it to cool down completely before attempting to clean it.

The materials needed for cleaning include a soft-bristled brush or sponge (to avoid scraping or scratching off the seasoning), mild dish soap combined with warm water, paper towels for drying and vegetable oil for preserving the seasoning.

In this post, I’ll take you through the steps involved in cleaning a cast iron grill press as well as give tips on essential precautions you should take while handling it.

Step-by-Step Cleaning Process

1. Preparing the Grill Press for Cleaning

The first step is getting your grill press ready as you assure safety for yourself and those around you. Start by turning off the grill, give the press some time to cool down then pluck of any loose or stuck on bits with a spatula.

2. Cleaning the Grill Press

The cleaning process starts with the use of a soft-bristle brush. Beginning from one end of the cast iron grill press, gently scrub away any food particles and grease embedded on its surface. As you continue, rub carefully in circular motions till every portion of the cast iron has been swept.

If there is stubborn dirt or burnt-on gunk, don’t reach for any harsher methods such as steel wool or metal brushes as they will only scratch the surface of your device and make it easy for rust to accumulate afterward. Instead, mix some mild dish soap and warm water in a bowl and use it to coat dirty spots on your grill press.

Let it sit a while (not too long to avoid rust) before using your brush again to clean it gently once more. Repeat this process until you’re satisfied that all the dirt is removed.

3. Drying the Grill Press

Patting dry with paper towels helps remove excess moisture and leftover residue from your cleaning exercise. Ensure that you take care not to miss any part, allowing it to air-dry completely before storing to prevent oxidation.

4. Seasoning the Grill Press

To restore and preserve the seasoning of your cast iron grill press, follow these steps:

  • Coat some vegetable oil to the surface of the grill press while it’s still hand-warm from washing.
  • On a low flame, heat up the seasoned cast iron device for about ten minutes. The warmth helps the oil seep into the pores of the material while providing an extra layer of protection against moisture and rust.
  • After this, use a paper towel to wipe off any excess oil as you turn off your burners and unplug your grill press.

5. Storing the Grill Press

Once your grill press is dry, ensure that it’s stored in a cool, dry place where it can’t be affected by any moisture or humidity. Use a storage container or appropriately-sealed plastic bag to protect it.
