I have this cookie sheet.
You know, i think they might officially be called jelly-roll pans, but here in the country (and almost everywhere), they're cookie sheets. Sometimes, they're also drip pans for sugary things like fruit pies, which i have a hunch - and not an honest memory - is how this cookie sheet got this exemplary blemish of black, thoroughly baked-on, well, who knows what it is really, it's black stuff. And it won't come off. Not with soap, not with a spatula, not with a sharp knife, not with harsh scrubbing tools. Nothing.
So, when i saw this post on Pinterest, called New Hope for Old Cookie Sheets, and i read about the miracle cleaning combination of baking soda, peroxide, and time, i thought, "i have those!" And i decided to give it a shot. The blog i read demonstrated and instructed that the stained cookie sheet should be "sprinkled" with baking soda, then sprinkled with peroxide, then sprinkled with baking soda. And i did.
And i waited. I don't know exactly how long i waited. But i definitely waited hours. And then i used a paper towel to reveal the new clean cookie sheet!
Well, that was disappointing.
I went back to the blog and read the comments and found that some folks had resounding results, while others had my results....nothing.
I'm really thankful for parchment paper.
That is all.
