How Do I Season My Grill Grates?

You can season your grill grates by following the seasoning process and using the proper equipment outlined below.

Things you’ll need:

Clean cloth or new sponge
Clean water
Cooking oil with a high smoke point
Paper towel
Mild dish soap
Wire brush
Cleaning gloves

Below, you’ll find the steps to seasoning your grill grates:

Take off the grates from the grill - if your grill is dirty, it is best to wear a protective pair of gloves to keep your hands clean.
Firmly brush both sides of the grate with a wire grill brush to get rid of any burnt meat and debris. Soak the grates in a bucket of soapy warm water for 15 minutes if there is significant build-up. Don't forget to clean your grill brush in the end.
Wipe the grates using a sponge, paper towel or wet cloth with soapy water. Rinse the grates thoroughly and let them air-dry completely.
1. If you have a new charcoal grill, this will remove any manufacturing oils.
2. If your grill is older, this will help brush away any excess oil and burnt foods.

Apply an even coating of cooking oil to both sides of the grate using a clean cloth. Use canola, rapeseed, peanut oil or vegetable oil since the grill is exposed to high temperatures.
Wipe off any excess vegetable oil.
If you have a new grill, coat the inside of your grill pit too with peanut oil or vegetable oil.
Preheat your grill for 15 minutes.
Put your grates back on your grill and let them bake for about two hours with the top on.
Let the grate cool. Your cast-iron grates will turn a shiny black while stainless steel, usually used on gas grills, turn dark bronze.
Get your grill fired up and get cooking. You won’t have to season your new grill for a few more months.

Note that canola oil is the healthiest choice for seasoning a grill. A 2023 systematic review and meta-analysis found that canola oil consumption significantly reduces serum LDL-c, total cholesterol, and LDL-c/HDL-c ratio compared to olive oil, suggesting that replacing olive oil with canola oil can have cardioprotective effects [2].

Extra Maintenance Tips

To keep your grill grates in tip-top shape, you’ll have to keep up proper maintenance.

Simple grill grates maintenance tips include:

Check your grill often to make sure everything is working well.
Remove excess oil and grease from meat to stop too much grease build-up.
Always clean your grill after cooking to avoid affecting the flavor of the food.
Season your appliance every few months to prevent the grill from rusting and to maintain its non-stick coating [3].
