I have a Hard Anodized frying pan which is a Member's Mark brand from Sam's club. I have had them for about 2 years. This is the only pan out of the set I have trouble with sticking. It didn't do this until recently. I know my husband forgot about the pan and left it on the burner and it needed some heavy duty cleaning after that. I got it clean but I am wondering if I need to do something to get it seasoned. I need some help. Is the pan ruined.
