I have an aluminum stockpot that I used to boil a piece of driftwood to place in my planted tank. It now has dark stains inside and I don't know how to get them out. I'm hoping that it can be saved for cooking. It never occurred to me that this would happen to it when I boiled that driftwood or I would have figured out another way to do it. Could someone please give me some advice on how to clean this pot out? I figured that someone on here has probably run into this problem before. Any help would be greatly appreciated. Thanks!
