Hey guys...new to the boards, and I had a quick question. I recently got a Lodge cast iron dutch oven that came pre-seasoned, and I used it once, following the directions, and the food came out fine. However, I was wiping it out the other night (and even though it was dry, and I had cleaned it according to the directins it came with), and I noticed a brown residue on the paper towel I was using. Is this normal? Is it starting to rust? I have no idea what to make of this, so if any anyone has any input on this, it would be greatly appreciated...I already tried to email Lodge about it, have not yet received a response. I'm admittedly new to the realm of cast iron, so if this is normal, that would be great, but I just wanted to be sure. Thanks!
