How To Clean Cast Iron Grill Grates

Cleaning cast iron grill grates can be a difficult task for many people. If you don’t know the right way to clean them, they may end up looking worse than before and your food will taste like rusty metal. Luckily, with these simple steps, cleaning cast iron grill grates is easy! After reading this blog post on how to do it correctly, you’ll never worry about maintaining your grill again!

For The First Time Use Of Cast Iron Grill Grates

When cooking on cast iron for the first time, thoroughly clean and season them. Seasoning the cast iron grates can help keep them from rusting and will also provide a nonstick surface.

Consider the following measures to take before to utilizing your grates for the first time:

    To remove dust from your kitchen grates, just wash them with warm water. Avoid soap. Using a cloth, thoroughly dry the grates.
    Cover the cast iron with your favorite cooking oil with a paper towel or natural bristle paint brush. Due of its high smoke point and low viscosity, many barbecue lovers choose peanut oil.
    Arrange the grill grate on an unlit grill. Then ignite the coals and heat the cooker to 350-400 degrees Fahrenheit. Allow about 40 minutes for it to stay there.
    Remove the coals and cool the cast iron.

This is the first seasoning of your cast iron. It is suggested that you season your cast iron on a regular basis. Some barbecuers season it immediately after each cook, while others wait for four to five cooks.

How Often Should You Clean The Grill Grates?

Food scraps left on the grill’s grates not only create a smelly mess, but also function as a perfect breeding ground for germs that may infect the items you cook the next time. Additionally, food that has been cooked on has been related to carcinogens that cause cancer. Prior to the next barbeque, it is essential that your grill is tidy and clean.

To make cleaning your grill simpler, clean it well before the grilling season begins. As you use the grill often, you’ll need to scrub it every week and thoroughly clean the grates every month or so. This will guarantee that your grill cooks effectively throughout the year and also extends the life of your barbecue.

How To Clean Cast Iron Grill Grates

Typically, grates are cleaned and restored. Nevertheless, if there is a significant buildup of rust that is difficult to remove or if it has eaten away major sections of the grill, it is feasible to replace the grill grate. Cleaning the cast iron grill grates will also assist in ensuring the safety of food put right on the grate.

Step 1: Cleaning Grill Grates of Debris

Scrub cast iron grill grates using a dry brush to eliminate food particles, rust, burnt or mildewed areas, as well as other debris. Scrape off the majority of it and, if required, use a metal scraper to remove big pieces.

Step 2: Rust Removal

Vegetable oil should be applied on a paper towel. Massage the oil into the grill grates and keep rubbing and wiping them clean until they are clear. Soak another towel with white distilled vinegar and use it to wipe away any residual rust stains. The vinegar is optional if the rust does not dissolve when the oil is rubbed.

Step 3: Restoring the Properties of Non-Stick

Coat the grill grates with an additional coating of vegetable oil. Preheat the oven to 300°F or preheat grill to low heat. Grates coated with oil in a hot oven or grill covered for about 30 minutes. Examine the grill grates and re-oil them if they seem to be drying out. Reintroduce the oven and inspect the grates every half an hour to at least one hour.

While applying oil to the grill grates, use hot pads and several sheets of newspaper towels. The oil should be uniformly covered on the grills, but not leak, to avoid the grease catching fire. If you detect heavy smoke warming the grates, quickly turn off the oven. Remove any extra oil from the grates before re-entering the oven.

Using a dry, clean paper towel, wash the grates. Then add another small coating of vegetable oil. Turn off the heat source. Bake or grill the grates until fully cool. When not in use, store the grill grates indoors in a dry location.

How To Remove Rust From Cast Iron Grill Grates

Based on the intensity of the corrosion, below is a step-by-step method for removing the rust.

Step 1

Pick a container large enough to accommodate the cast-iron grates. It should be filled halfway with white vinegar and 1 cup baking soda. Ascertain that the grates are completely immersed. Keep it for the night. Allow it to rest for a couple of days if the corrosion is bad.

Additionally, different chemical treatments, such as Easy Off, may be used to clean the corrosion. Ensure that the residue is thoroughly rinsed afterward.

Step 2

Eliminate any grates that may be present in the containers. At this point, the container will look much more attractive than it did before. Scrub away any residual rust with steel wool and a toothbrush.

It’s preferable if you have an electric drill that comes equipped with a selection of wire brushes. This should not be difficult to do with an electric tool. Additionally, it may be used to clean the rust prior to exposing it to the baking soda and vinegar.

All that cleaning will restore your scratches to their original state of pristine metal.

Step 3

Wash the grates well to remove any dust and corrosion. Then, preheat the oven to a low temperature and gradually dry the grates.

Additionally, you may dry the area with a cloth. Ascertain that no water remains. Rust may reappear rapidly if you are not vigilant.

Step 4

The final step is re-season the cast iron grill grates. That is now possible inside the oven. However, I have discovered that it is possible for the house to become smoky and stinky. The most effective method is to utilize a grill.

Heat the grill to 350F-400F on a gas or charcoal grill and then retain that temperature. A bit extra is OK as well.

Coat the grates with oil many times. Bake them with the cover closed. Continue to examine them every 20 to 30 minutes. Repeat until the grates are completely black, glossy, and smooth. The whole procedure should take no more than a couple of hours.

When the grates are ready to use, remember to season them with salt both before and after the next cooking session. They should endure for an extended period of time.

How to Keep Your Cast Iron Grill Clean for a Longer Time

After cleaning your grill, you may use the opportunity between uses to wash the grill’s surfaces with hot soapy water while it is still warm. Food and grease will easily glide off. Ensure that you wipe it thoroughly with a sponge soaked in hot water to remove any sticky residue. Season to taste if food becomes stuck to the grill.

If you’re using a brand-new cast iron grill, you’ll want to season it. This first seasoning ensures that food does not cling and that cooking is more uniformly distributed, while oiling the grill prevents it from rusting. Disinfect the components with hot soapy water. Your grill should be cleaned and dried. Season your new cast iron grill by following these instructions.

  • Clean the grill well and use a paper towel to apply a thin, uniform coating of cooking oil or solid vegetable shortening. (Avoid olive oil, which may cause stickiness.)
  • Ensure that you coat all cooking surfaces with oil. However, take care not to apply too much, as it may get sticky.
  • For about an hour, heat the grill to around 400°F. After they have been cooked, the grill should not be shiny.
  • Allow the grill to cool completely before using.


Cast iron grill grates are a labor of love. As long as you take the time to properly care for them, they’ll last longer than your grill itself! With that in mind, we want to share with you how easy it is to clean cast iron grill grates and keep them looking like new each time you use them.
