I have a couple aluminum baking sheets, and when i wash them, then dry them with a towel, it turns the towel black? why is this? are these still ok to use? Ive been putting one of those silicone baking sheets or parchment paper on the sheets because of this. but i cant really do that with the cake pan. so how do i stop it from doing this?Aluminum reacts to anything acid and a lot of dishwashing detergents are on the acidic end of the ph scale and that causes oxidation which is the black stuff you\'re getting on the towel. I use commercial aluminum baking sheets when I bake. I like their heavy weight, even browning and NO burnt cookie bottoms. Hot water and a tiny, tiny bit of dishwashing detergent works to clean them. The less you expose the sheets to acidic things, the less black stuff you have. To remove it, I just take one of those sponges with a nylon scrub pad that\'s safe for non-stick cookware and give it a scrub. I don\'t soak my baking sheets or put them in the water; I put a drop of the dishwashing soap on the sponge, work it into a foam, wash and rinse quickly. Barkeeper\'s Friend works well on anything the dishwashing liquid won\'t take off also. It\'s normal for the type of material it is but what you use to clean them does make the problem worse. If you don\'t create the black stuff, you don\'t have the problem.an basic recipe for honey baked bananas. components: 6 bananas 2 tablespoons melted butter 2 tablespoons lemon juice a million/4 cup honey guidance: Peel bananas, halve lengthwise and place in a shallow baking dish. blend at the same time melted butter, lemon juice, and honey.
