My lovely hubby replaced the bottom burner/heat coil element of our oven, put the racks and pizza stone back into the oven and told me its done and ready to go. This morning I turned on the oven, took a 15 minute shower, came out and smelled plastic burning. Thought it was burning off the "newness" of the burner. I opened it up wondering why that plastic smelling....lo and behold, on the bottom there was his needle nosed pliers, plastic syrofoam handles melting..... It needs a cleaning....I know the rack will be fine in cleaning cycle but what about the pizza stone? It was so lovely seasoned...is it safe? Or do I need to wash it with soap and water and reseason it again? Or the fumes of the plastic can do it harm? I am going to have some choice words for him when he comes home from work! So right now I will be waiting for your responses on the pizza stone. I have three more unused stones but it will take three years to get that seasoned I had!
