Bought a craycort cast iron grate for my performer last xmass. while i really like the product it sure is a pita to keep it clean.I thought that seasoning it would help, pam, veg oil, however if something burns on it even a welding wire brush has a work out. I just cant get it to release the carbon. That said, anyone have a better idea, or process? Maybe power wash it and re season it in the oven?
