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:

  1. 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.
  2. 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.
  3. 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.
  1. 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.
  2. Wipe off any excess vegetable oil.
  3. If you have a new grill, coat the inside of your grill pit too with peanut oil or vegetable oil.
  4. Preheat your grill for 15 minutes.
  5. Put your grates back on your grill and let them bake for about two hours with the top on.
  6. Let the grate cool. Your cast-iron grates will turn a shiny black while stainless steel, usually used on gas grills, turn dark bronze.
  7.  Get your grill fired up and get cooking. You won’t have to season your new grill for a few more months.

#3 Better Flavor

One of the reasons it tastes so good is thanks to seasoning your grill.

Fats and juices that drip down the grates and pit are marinated into the grilled meat via vapors. You aid your grill's distinct flavor when you keep your grates oiled and seasoned up.

Regular seasoning your grill will prevent coal dust deposits on your grate and food.

#4 Extend the Life of Your Grill

Regularly seasoning your grill grates can extend its grilling life. Season your grill grates regularly to prevent rust and damage and provide a good non-stick surface.

“Charcoal or gas. Both give excellent results, so choose the one that best suits your style of cooking.”
