I'm a little embarrassed to write this review; it's been ~6 years since my last oven cleaning... After seeing the results, I couldn't help but spread the word. Sure, it took some beer, a little John Mayer, and a lot of elbo grease, but I got the job done, thanks to this handy little product. It did require two treatments; however, given the circumstances, this product accomplished quite a feat in just an hour. The attached pictures speak for themselves.
