Query: Makes everything taste like metal

I followed the directions each time I washed it - and it is a pain! You can't soak it in water, you have to dry it in the oven... Even with all that, it can never be perfectly clean and it leaves a blackish liquid when used to cook: under it (on your stove) and on the food. I am getting disgusted by it, wondering what that's funny taste and smell on my food. It works well to grill meat, making it almost as perfectly cooked as on the "real" grill, but I can't trust it. Will trash it. What a waste.
