You can “unstick” burnt pots and pans by pouring in some Coke and bringing it to a boil. Take the pan off the heat and carefully use a scrubbing brush to stir the soda – the food should come right off. I hate scrubbing burnt pots and pans. So pour some cola (bubbly Coca-Cola works best) into the pan and bring it to the boil. Use a scrub brush to stir the cola and the burnt on food comes right off. It’s a strong enough acid to clean the pan but mild enough to not damage any non stick coating.
