Life happens. We put something in the oven or on top of the stove and forget about it. Removal of baked and burnt-on foods can be a time consuming task if we turn to scrubbies or sponges.
Instead, relax and let baking soda come to the rescue. Sprinkle a generous amount on the pot, pan, or casserole dish (but not aluminum) and add hot water to a level that covers the burnt food residue. Let the mixture soak for about 15 minutes and check to see if the food has softened. Finish cleaning as usual.
If the food is really stuck, let it soak overnight. This method has worked for me every time and made cleanup super easy.
