Hi, I want to know how to clean a pizza stone I use in my oven to cook my pizza's. I got one response to leave it in the oven when using a self cleaning oven, however., I dont have a self cleaning oven. Is there another way to clean the stains and dried food particles other than washing with plain dish soap and water? This doesnt seem to remove the stains or dried oil. I dont want to use harsh chemicals on it, perhaps someone knows another way to clean it and remove the stains. Thanks, Lucy Rose
