I was showing my young nephew how to clean-up some small parts with a
crimped wire cup brush in my drill press. He was just infatuated with the
way rust and crud were replaced with bright shiny metal. I've seen that
look before! After I was confident he wouldn't lose his eyes or
fingerprints I let him discover. A few hours later he presented, with
great pride...my grandmother's cast iron frying pan! It looked newer than
the day it was cast!

I bet he stripped off that smooth black anti-stick anti-rust layer
formed by decades of frying and wiping but never washing. It may be
time to re-season the pan.
