Baking soda is so useful. Was washing dishes today and one of my pans had burned oil in the bottom of the pan. While I had made an attempt to remove it by scrubbing alone, this was not adequate. So I put some water and enough baking soda to cover the bottom of the pan and cooked it on medium heat about 20 minutes until it was boiling. Then I put it in the sink, cooled it off a bit, and scrubbed with the sponge. Had to repeat that one more time, but was able to get the burned oil off.
