This do it yourself trick has two sides to it. Over at One Good Thing by Jillee, she shares this trick with hydrogen peroxide and baking soda to clean the brown gunk off of pans. She claims that when left alone for a few hours, it will wipe up with little to no work. Some of her photos show amazing results between the before and after photos.
Unfortunately over at Green Idea Reviews, they felt that this method fell short. Their results weren’t quite as amazing and they felt it failed. A lot of their reviewers had the same results. So the question is which one is right? Potentially both of them. Green Idea Reviews used a much less grimy pan, so it probably wouldn’t have been as drastic of a result anyways. Jillee still had some grime and baked on gunk left on her tray even after the miracle clean, so it stands to reason that with less gunk on your pan to begin with the product might not be as apparently drastic. Those who responded to Green Idea Reviews agreed that they had no success, while those responding at Jillee all seemed to be excited to have gotten the tips, and some even raved about how this way of cleaning cleaned a old junk toaster oven to like new condition.
My own personal opinion is that it’s probably 6 of one, half dozen of the other. Those who ran into problems might not have used enough of the products to work to the best of it’s abilities, Jillee might have rubbed a bit more than those who found it didn’t work. They might not have had enough grime, so it didn’t seem like it worked at all. To me anything that will help get off the grime, whether it worked a little, or whether you had to apply elbow grease, if it works better than dish soap, then it is worth a try.
