so i just got a new aluminum brew pot. The instructions that came with it say "wash with cold water and mild soap, dry with a cloth. Then begin to season your pot. To season it, put a thin layer of cooking oil in bottom. Heat until it becomes quite hot but not hot enough for steam to come from pot. Then cool it down. Once cool, heat it up again to the same condition. Then cool it down. Now your pot is seasoned" I have not gotten to this point yet. I washed it with cold water and soap and there is still black/blue coming off on the cloth when I dry it. Anyone else have this issue?
