How To Clean A Burnt Pan | Zyliss UK: "White vinegar is an excellent solution for salvaging burnt non-stick pans. Once the pan has cooled, pour in a generous glug of white vinegar, along with enough warm water to cover the burnt areas. Stir in two tablespoons of baking soda, heat the mixture up, and bring it to a boil for a couple of minutes. Use a wooden spoon or silicone spatula (avoid metal utensils) to remove as much of the burnt substance as possible."
