To get baked on food off a muffin pan fill the sink with some hot water and add some dawn dish soap or any other soap.
Then soak the muffin pan in the hot water and soap for 30 minutes.
Next sprinkle some baking soda on the muffin pan and then scrub the muffin pan with the baking soda and the warm water.
The baking soda, soap and warm water should help to loosen the baked on food from the muffin pan.
To keep food from sticking to the muffin pan when baking spray the muffin pan with some PAM cooking spray.
This will help the muffins slide out easily when they are done and prevent food from baking on the pan.
You can also put the muffin pan into another baking pan filled with soap and water and baking soda.
Then put the muffin pan and other baking pan in the oven and allow the water to get hot to help clean the muffin pan.
Then use a toothbrush or other scrub brush to help clean the baked on food off the muffin pan.
