I have one of these cast iron grill/griddle pans... the griddle is fine, however, the grill section has a good deal of build up in-between the grill lines. Some of it is coming off just by using a spatula and I don't want the black bits on my food. I tried to clean this but all of the suggestions are not working. Can I scrape off the black stuff and reseason?
Cast iron responds well to sanding. I thought I had damaged my c.i. frying pan because of pitting - I thought in the metal. So I decided to re-sand the thing by hand. Turned out the pits were only in the "seasoning" layer. Sanded it smooth, finishing up with fine sand paper & steel wool if i remember right. Anyway all by hand. Seasoning layer turns out to be pretty soft. Whole thing took a few days, on and off. Re-seasoned, & all right again now.
