Query: sturdy, but hard to clean

This is definitely a sturdy piece of equipment. Very solid. However, I do not understand in what universe this could be considered "non-stick". Believe me, if you cook something with BBQ sauce on it in this pan, you will NEVER be able to get this thing clean. My new strategy will be to use foil over top. Hope that works better.
