Why Seasoning Your Grill is Crucial
Seasoning, or curing, your grill isn't just about aesthetics; it's about extending its lifespan and ensuring optimal performance. The high heat process creates a protective layer on the steel, preventing rust and corrosion in humid conditions. This is especially important for grills that experience frequent temperature changes.

Think of it like seasoning a cast-iron skillet—it creates a non-stick surface and prevents sticking and rust. A well-seasoned grill will heat more evenly, providing more consistent cooking results. This process significantly improves the grill's longevity, making your investment worthwhile.

Neglecting this crucial step can lead to premature rust and degradation of your grill. It's a simple process that yields significant benefits in the long run. Investing the time to properly season your grill is an investment in its long-term health.
Seasoning the Gas Section
Start by lightly coating all steel surfaces and grates of the gas section with vegetable oil. Ensure a thin, even coat; you don't need a heavy application.

Preheat your grill to 500 degrees Fahrenheit. Maintain this temperature for about two hours, allowing the oil to bake onto the metal. You'll see the oil smoking off—that's a good sign!

This process creates a protective layer, similar to seasoning cast iron cookware. The high heat will polymerize the oil, creating a durable, protective barrier.

Seasoning the Charcoal and Smoker Sections
Repeat the process for the charcoal and smoker sections. Remove the grates and apply a light coat of vegetable oil to all unpainted metal surfaces. This includes the inside walls and any other exposed metal components.

Light a small fire using charcoal in both pans. Leave the vents slightly open to allow for airflow. Let the grill cook for two hours at a lower temperature.

Increase the heat after two hours by adding more charcoal and adjusting the vents to be half-open. Maintain a high temperature (around 500 degrees Fahrenheit) for another two hours to fully cure the metal.
Maintaining Your Seasoned Grill
After each use, let the grill cool down and burn off any food residue. Scrape the grates clean and apply a light coating of oil to prevent rust between uses.

Periodically, repeat the full seasoning process to maintain the protective layer. This ensures your grill remains in optimal condition and extends its lifespan.
Using a grill cover is also a good way to protect it from the elements. This will help maintain the seasoning and protect your investment.
