To season new grill grates, start by thoroughly cleaning them with warm soapy water to remove any manufacturing residues, then dry them completely. Next, apply a thin, even coating of a high-smoke point oil like canola or peanut oil to both sides of the grates. Heat the grill on medium-high (about 180-200°C or 350-400°F) for around 30 minutes with the lid closed, allowing the oil to bake and form a protective, non-stick layer. After heating, let the grill cool completely. This process not only prevents rust but also creates a non-stick surface for easier cooking and cleaning. For cast iron grates, repeating the seasoning process 2-3 times before first use is recommended for better protection and longevity.
Detailed Steps:
- Clean Grates : Wash with warm soapy water, rinse, and dry thoroughly.
- Apply Oil : Use a high-smoke point oil (canola, peanut, vegetable, or avocado oil). Coat both sides of the grates lightly with oil using a cloth or spray bottle.
- Heat the Grill : Turn the grill to medium-high heat (~180-200°C or 350-400°F), close the lid, and heat for 30 minutes until the grates darken.
- Cool Down : Turn off the grill and let it cool completely before use.
- Repeat if Needed : For cast iron grates, repeat the oiling and heating process multiple times for the best seasoning.
Tips:
- Avoid using oils with low smoke points (like olive oil) as they can burn too quickly.
- Seasoning helps prevent rust and food sticking and improves grill performance over time.
- Regular seasoning after cleaning maintains the protective layer.
