Well...if you have a self cleaning oven and filthy, sticky, mucky cookie sheets and pans....then you can kill two birds with one stone!
**WARNING** This is NOT intended for those pans with Teflon or a non stick coating.
My cousin had a pan in her oven when she went to set the self cleaning feature, and the result is amazing!
So much so, that I had to vlog it!
Just put your gross pan in the oven on the rack and set it to self clean. And EASY PEASY
