My cast iron is 4 years old and every time I use scotch-brite on it, I have to spend hours stinking up my house with flaxseed oil to reseason the pan because scotch-brite makes little dots of shiny iron show up.
I don't mean for my salty comment to justify a not-ideal method. But for this topic, the proper use of the pan will generate a good seasoning as it is used.
That seems excessive to me. I use my cast iron every day, clean it off with steel wool, and just throw a little oil on there. No fancy prep, and it cleans up with less effort than 2 year old no longer non-stick pans
