Hi, I purchased a DO at an estate auction. It was in really rough shape. I cleaned it using the Easy-off method for about a week. I tried using an sos pad to remove the unknown spattering of some sort, but it appears to be on the pan forever. The pan itself is still usable. My concern is the lid. It had the clean-easy enamel on it, but it is peeling off. My cleaning method failed to remove it. Can this enamel be removed another way? Is it worth saving, or should I buy another lid? The lid is totally unusable as is. I hope these pictures can be viewed. Thanks for any help.
