Nothing is worse than after a delicious dinner having to clean the casserole pan from hard, stuck-on, baked food. Make your life a little easier by filling the pan with hot water. Now add 2 black tea bags and let sit overnight. In the morning, pull out the tea bags, pour out the water to wash as usual. The mess from last night should wipe off with minimal scrubbing because the compounds in the black tea help loosen the greasy, stuck-on food while the long soak softens any hard residue. If there are still some stubborn spots, sprinkle some baking soda over the areas. add water and scrub off.
