A few weeks ago I made some homemade bread pudding. We had a few servings of it, the weather got hot and humid, and I soon learned that mold really likes bread pudding too. The pan is a stoneware pan.

I rolled up my sleeves, got some really hot water, and scoured it as best as I could but it still has dark spots and a moldy "funk" to it. I don't really want to use it like this. Is there a way that I can clean this pan or is it a lost cause?
