Thank God someone approves of my little projects. I got a lecture from my wife for running the the self cleaning cycle with > 85F temp outside. And I thought I was smart for making use of low electricity rates (holiday today in Canada).
Yep been there done that! Found out my weed burner does the same thing, outdoors and faster! Just need a non flammable place to do it! Here's a pic of the weed burner in action, unfortunately not burning cast iron! . I'll have to get one next time I do some cast iron..
