hi, my sister bought me a couple of wilton cake pans from a yard sale, however they are discolored meaning they dont have rust or any silver missing it just looks used a lot of brown spots from a lot of baking i guess. What is a good method of getting them clean? i used hot sudsy water ,but they still havent brightened up. thanks for any replies

you can try easy off oven cleaner. It works great on my baked on pans.Hope it helps.
