I've baked some pie on my anodized aluminum pie pan but things went awry, and some dough was stuck to the pie in the end; I assume it was overbaked? I could remove the pieces but stains were left behind. Here are pictures:
Are these stains a big deal? Do they mean the pan or anodization has been damaged? What can cause them, or how to avoid them?
I've looked around on how to clean and remove these stains, but have found contradictory advice on using baking soda, or other methods.
Is it possible to remove these stains, and if so, how?
