Not sure If this could hurt anything to do but I just found a great way to clean my lead pot. I got all of the lead I could out of the pot and heated it up enough to melt any remaining lead. Then I got an old pair of kitchen tongs and a 0000 fine steel wool pad and wiped out the inside of the pot. All of the remaining bits of lead in the pot were absorbed into the steel wool. It did start smoking a little bit but I was outside with a fire extinguisher handy. After Wiping out the insides of the pot the only thing left was some fine black powder which I would imagine to be iron oxide. I then let the pot cool down for several hours and cleaned it out with some alcohol and it is spotless. Let me know if I am doing something I shouldn't be. It worked great and the only possible issue I could think of would be the possibility of the steel wool bursting into flames.
