While most non stick pans will develop light discoloration over time—especially if the surface of your pan is a light color—deep, dark discoloration is a sure sign that your pan's coating is wearing out.
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.
We advise replacing your nonstick pans whenever the coating starts to degrade or is scratched—or about every three to five years.
When your pans are scratched, some of the nonstick coating can flake into your food (the pan also becomes stickier). This can release toxic compounds... With moderate use, nonstick pans last only about five years. If your pan is damaged, throw it out to be on the safe side.
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.
If the scratches are superficial, a non-stick cookware repair spray can be used to create a protective layer over the scratches. Be sure to read and follow the product's instructions carefully before use. Shake the can well before use and hold it 8-12 inches away from the surface.
If the non-stick (PTFE-coated) cookware is worn out, it should be disposed of in the trash. Non-stick cookware is not recyclable due to the PTFE coating and are not accepted in curbside recycling carts or at the Drop-Off Station or Recovery Yard.
A: Calphalon stopped manufacturing our nonstick using PFOA back in the third quarter of 2012. We have then since moved to a formula that is completely FDA approved.
To test the non-stick coating, use a small amount of water and drop it in the center of a thoroughly dry pan. If the water starts to bounce around and roll about the surface, its non-stick coating is intact. If the water spreads out and “sticks” to the pan's surfaces, it shows the coating has deteriorated.
It's important to replace nonstick pans once the nonstick coating wears out. Signs that it's time to replace a pans and tawa include: 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.

Teflon® is a registered trademark of DuPont and a brand name for polytetrafluoroethylene (PTFE) a nonstick finish. While Calphalon cookware features polytetrafluoroethylene-based nonstick finishes, we are not associated with, nor do we use, Teflon® branded products.
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.
According to TheKitchn, you can expect about five years out of your non-stick pots and pans; it's time to retire anything with a surface that's pitted or starts to peel (to make sure it lasts that long, they offer some tips for taking care of them). Are you looking around your kitchen thinking it's time to go shopping?
To check if your car has Teflon coating, you can try pouring a few drops of water on the car's paint. If the water beads up and rolls off the surface, it is likely that your car has Teflon coating. However, this method may not always be accurate, and it is recommended to consult a professional to confirm.
Nonstick Pans Do Not Last Forever
When they start to appear warped, discolored or scratched, be sure to stop using them.
Damaged Non-stick Pans Should Not Be Used
While modern non-stick pans are quite safe when used properly, be careful not to use these when the coating is damaged. For example, the coating could be damaged due to long time usage, or abrasion or scratching by hard objects during cooking and washing.
