Can't clean my cast iron grill - I've tried everything!

Does anybody have any other ideas about how to get that hardened black stuff off a brand new, just used once, cast iron grill? I tried Kosher salt then scrubbing with steel wool, I rubbed it with oil then baked it in a 500 degree oven for an hour, even scraped at it with a steak knife which took off a lot more than the gunk. My new grill is now streaked with black crust and lighter colored streaks where the knife stripped off the outer coating.

  1. On Cook's Country or America's Test Kitchen last week, Kimball cleaned a gunky cast iron skillet by heating it with oil on a stove, then scrubbing with a scouring pad. After the burn-on stuff was gone, he rinsed and dried it. You need to wear gloves. A wad of aluminum foil can be used as a scrubber, too.

    1. Oven cleaner and a bag. When you say grill, do you mean like a grill pan or grates from a grill?

      Rubbing it with oil and then baking it will just add another layer of seasoning over everything probably. Best to start over again. Oven cleaner and a bag. Or a lye solution?

      Then read this post which is the best cast iron seasoning instructions I've seen

        It's a two-burner stovetop grill pan. Thanks for your response - I'll look into using oven cleaner and a bag (I've never heard of that one)

          Expanding on the "oven cleaner and a bag" method - Here is a wonderful how to:

          I've used this method on my own pans with great results, but like someone else mentioned, this will strip your grill of the gunk and seasoning. However he kindly includes instructions on how to reason as well.

          Good luck!

      2. I use coarse sea salt on my cast iron pans. It acts as an abrasive when you scrub it

        1. Light a big fire in your grill. Put the grates over the fire. Let the fire burn for an hour.

          Everything that was on the grill should be completely incinerated.

          1. This doesn't directly answer your question, but I wouldn't do anything. This is a common "problem" with grill pans and it is expected. You won't be able to get the black stuff completely out. Some of the cleaning techniques here will strip the seasoning away (oven cleaner) and then you have a whole new problem on your hands. You've already stripped off some of it with that knife.
