I just got a very old cast iron pan from my MIL that is not in good shape and I have used sandpaper to clean it.
This is what it looks like right now. Have I sanded it enough yet? Does it look ready to reseason? Does ALL of the black color need to be gone? When I run my finger around the inside of it, it feels nice and smooth, even though some of the black color still remains. I'm hoping you say yes, because it has taken me hours to get it this clean!
Thanks for your help!
