If the grates are really dirty, soak them a second time to help soften and remove more gunk without expending extra elbow grease. Or, try the new Sienna Grilltastic Grill Steam Cleaning System. Fill this electric scrubber with water, plug it in and in seconds the combination of the dishwasher-safe stainless steel brush head and hot steam will be blasting grease from your grates. (It cleaned our GH Test Kitchen grill so well, our recipe testers asked if they could keep it.) Finally, rinse the grates well and let them dry.
Check the ignition system. Turn the gas off, and test your ignition button to see if it creates a spark. If both the pressure regulator on the gas tank and the ignition system are running normally (meaning the pressure regulator is tracking and maintaining correct gas tank pressure, and the ignition system is sparking and lighting correctly), you can finish testing the grill by turning the gas back on and lighting the grill up as you normally would.
You just brought home your new Char-Broil® grill. Before you start grilling, it's vitally important to learn how to season your Char-Broil® grill before its first use. Seasoning the grill is the process of heating and oiling the grates to keep your grill operating at its prime. Oil protects the grates from rust and makes them easier to clean. Season your grill every time you use it and your grilling partner will be with you for many years.
Clean the exterior of the grill. Soapy water is the safest cleaning solution for most gas grills. Just make a cleaning solution with water and a squirt or two of mild dishwashing soap. Wipe the exterior of the grill with the soapy water, use a rag dipped in clean water to remove the soap residue, and then dry the exterior of the grill thoroughly.
