There is no way to re-surface ceramic pans once they are scratched and damaged. We have found most sprays available are not food safe and should be avoided on ceramic pans. By digesting those harmful chemicals, you can seriously cause damage to your body and long-term health. The better method is to avoid resurfacing completely and purchase a new pan. Once you made your purchase, make sure you use soft cooking utensils on the pan and avoid high heat. This will prolong the life of your ceramic pan and ceramic coating.
