I heard that you're not supposed to apply water to a cast iron pan, at all.
I have the exact same pan, a 12" Lodge, and I haven't "cleaned" it with water in the 4 months I've had it. When something sticks, like melted cheese or burnt ground beef, I'll sprinkle in some coarse salt and scrub the inside of it with a dry rag. I'll finish by adding some oil and smearing it around the pan while it's still hot. I haven't had any problems with flaking after the first week or so, and I use it a lot (which probably helps).
I began this Primal journey on December 30th, 2009 and in that time I've lost over 125 LBS.
