If the coating looks deeply scratched and dry. If the surface is looking whitish and dry, it's likely that the nonstick coating has worn away to an extent that will make it quite clingy. Use extra fat to avoid sticking, but if you're constantly struggling with it, it's probably time for a new pan.
Non-Stick Coating Damage: If the non-stick surface is scratched, peeling, or flaking, it's time to replace it. Damaged coatings can lead to food sticking and may release harmful substances. Warping: If the frying pan is warped or doesn't sit flat on the stove, it can lead to uneven cooking and may not heat properly.
Scratched or chipped coating
With old nonstick pans that contained PFOA, scratches and chips were a clear sign that your pan was no longer safe to use, as the coating could flake off and get in your food.
Not all non stick pans are created equal, so they can range in length of life. While most non stick pans last an average of two to three years, pans of a poorer quality may yield fewer uses before the non stick coating wears off. Alternately, higher quality pans may last longer than three years with the right care.
Flaking or peeling: If you see the nonstick surface peeling off or flaking into your food, it's time for a new pan. The coating is breaking down and can end up in your meals. Loss of nonstick performance: If foods, especially eggs, start to stick when they are never used to it, the nonstick finish is wearing thin.
