The cast iron skillet is very attractive and it matches my other Rachael Ray cookware. I have never used cast iron before so I thought I’d give it a try.  First of all, it is heavy. I have arthritis in my hands so I have to be very careful lifting it. Second, I thought I prepared the pan properly before simmering chicken breasts in it. I carefully wiped the skillet out and gently, lightly washed it. I expected it to look unused as it looked when I bought it. No, there is a dirty looking film on it. I don’t want to use it again because of the way it looks, but I don’t know what to do. Do I try to re-season it, do I try to wash it again so it is clean?  I feel like I just wasted my money on this cast iron skillet that I was so excited to get.  HELP!
