Thank you for following the instructions, Janice, as it is very important. To restore the non-stick performance, we recommend soaking the cookware overnight in hot, soapy water and thoroughly washing the surface the next morning. Besides, as you can see on the bottom, the small holes on the iron base plate expose the aluminum bottom of the piece to the air. The exposed aluminum oxidizes in the air at high temperatures due to its nature. Therefore, after repeated use, the aluminum at the bottom will discolor. However, we have a tip for you to clean. Baking soda: Mix a suitable amount of baking soda with water to form a paste. Apply the paste to the oxidized aluminum surface, let it sit for a while. Then gently wipe with a damp cloth, and finally rinse with clean water.

We are sorry to hear about your experience, Charlie. We suggest when using the metal steamer insert, place it carefully on and off any locations. Never use hard objects on the nonstick surface. And always place a piece of paper towel or cookware protector between each other.
