After years of using a Weber kettle grill, I just upgraded to a Char Griller. It looks like a big improvement (adjustable coals, built in thermometer, optional smoke box, and cast iron grates).
Any advice on how to care for the cast iron grates? I never cleaned the Weber grates after cooking. Instead, I let all the crud sit. The next time I lit a fire, I could easily scrape the grills clean when they heated up.
Can I do this with the cast iron grates? Or do I need to scrape them down after cooking?
