I have food burnt to my pan...

Most morning I cook eggs which stick to the pan. When I am done, I add about 1/2 inch to an inch of water, add some dish soap, and baking soda. Let it sit for a little while, then it is an easy clean up. This works for just about everything. Brian made a roast in the oven without tin foil on the bottom of the pan. I did this but let it sit overnight. The burnt on stuff was a snap to clean.
