So I am an idiot…

So I am an idiot…

I was cleaning my kitchen and in an effort to clear off all the counter space so I could do a good deep clean, I put my plastic cutting board in the oven for a min. Well, I forgot about it. My hubby came home later after I had left and wanted to make his lunch. He preheated the oven. Yes now I have melted plastic in my oven. I got the majority of it out. There is still some stuck to the bottom. Anyone have any tips on how to get this off? I have tried scraping. I used a wooden thingy so I wouldn't scratch up the oven. I am thinking of running a self clean cycle on the oven but don't know if that would work. I know it will stink to high heaven. TIA
