How do I prepare and care for the griddle before and after use?

The griddle ships unseasoned. Before first use, coat the surface with a high-smoke-point oil (such as vegetable or flaxseed oil), then heat gradually to build a protective seasoning layer. After cooking, clean gently, dry thoroughly, and apply a thin oil layer to prevent rust.

• Season once before initial use, then maintain seasoning with light oiling
• Safe up to 500°F when used on your gas grill as directed
• Do not disassemble the heat plate; avoid metal utensils to protect seasoning

What accessories are included, and how do they make grilling easier?

The package includes the full-size griddle, a water- and rip-resistant 600D Oxford carry bag, a pair of silicone heat-resistant gloves, and replacement handles plus screws. These extras protect the griddle in storage and let you swap grates quickly without waiting for the surface to cool completely.

• Durable 600D carry bag protects the griddle from weather and scrapes
• Silicone gloves allow safe handling when swapping plates while warm
• Replacement handles and screws included for straightforward installation

What cooking styles does a full-size griddle enable on a Genesis II grill?

Installing this flat top gives you a continuous, even surface ideal for foods that need full contact heat. It expands your grill’s repertoire: delicate seafood, breakfast items, stir-fries, vegetables, and quick-seared steaks all perform well on a flat top.

• Even sear and browning across the whole surface for proteins
• Great for sautéing vegetables, stir-fries, and pancakestyle breakfasts
• Use the two-mode setup to switch between grill grates and griddle quickly
