I bought a house built in 1958 with the original cooktop stove -- an O'Keefe and Merritt. The burner pans have so much baked on/*in* grease and whatever, they are impossible to clean to the point that they look like the stainless steel (presumedly) pans they once were. They look predominantly black. I can get the surface clean but can't get down to the stainless steel. I'd prefer to shine these up but all attempts thus far have failed. I have used the "Astonish" tablets and paste. I've used non-abrasive cleansers. Nothing. Any suggestions for getting them clean and shiny?
Alternatively, any hot tips on where to get new ones? Each 2-set burner has one fused pan with wells underneath each burner. If that makes sense.
