How to make a "nonstick" waffle maker nonstick again? - farberware waffle maker

I have a waffle iron core Farberware for many years. He is black, non-stick removable plates, which almost always washed their hands. When I was in the dishwasher, and since then it is not to stay. The waffles stick as cement ruins. I have tried to smear with oil and soaking in vain with Pam before cooking. Has anyone tried? Are they now ruined? Or maybe the dishwasher was an accident, and they need a good deep cleaning? Any thoughts ...
