In my home pots and pans (calphlon) I've had them over 10 years and thought the nonstick surface was wearing out as food was sticking. I've only used the nylon stuff over the years. When I called the company about the lifetime guarantee, they said for me to try "Soft Scrub" and the "Blue" scrubby pads. Sure enough, my nonstick coating wasn't coming off, but rather years of baked on stuff was covering it up. Fixed them up right away. Perhaps the same applies to your nonstock cookwear.
