My Char-Griller has the cast iron grill plates. When I was purchasing it, I thought, how cool is that! I love using cast iron cooking ware and know how to take care of it, keeping it seasoned and all. I seasoned them like I was used to with cast iron, and in accordance with the instructions. When I was done cooking, I coated them again with cooking oil, and let them sit in the heat to set. But after a couple of weeks of not using it, I found that they had rust on them. So I scrubbed them down, and re-seasoned them. Cooked on them, wiped them down (no soap, of course), and then coated and heated them to set the oil. After a couple of weeks, guess what... rust again. This time, I lightly dusted off the rust, wiped them down and oiled them really good, then went ahead and cooked. This time I didn't clean them off, just sprayed real well with oil and put it away. There is stilla little rust showing up, but where I have been cooking, there is a build up of blackened oils. I just figured I'd rather cook on that than on the rust, so I have been doing that. Every now and then, though, some of it flakes off and gets in the meat. I was hoping I could get those grates to look like my frying pan cooking surface and avoid the rust. Any ideas?
