You should throw away cooking pans when the non-stick coating is deeply scratched, flaking, or peeling, the pan is warped and uneven, the handles are loose or cracked, or if you see rust or significant discoloration that won't clean off, as these indicate compromised performance and potential safety issues, especially for non-stick pans where the coating could break down and mix with food. While metal pans last longer, replace them if they're severely damaged or no longer cook evenly.
Is it time to throw away your pots and pans?
A good rule of thumb is to replace them approximately every five years. Look at your pans frequently. When they start to appear warped, discolored or scratched, be sure to stop using them.
Chipping, Peeling, or Heavily Scratched Cooking Surface
For nonstick cookware, chipped or peeling coatings can release harmful particles into food. Deep scratches in stainless steel or carbon steel can harbor bacteria and degrade results. Replace pans when scratches or peeling affect safety or cooking quality.
Some types of imported cookware products made from aluminum, brass, and aluminum alloys known as Hindalium/Hindolium or Indalium/Indolium have been tested by FDA and state partners, and have demonstrated the potential to leach lead under conditions designed to mimic their use in contact with food.
Recycling Nonstick Cookware
If you have nonstick cookware coated with PTFE, recycling options are limited. The coating needs to be removed before the pan can be recycled. Once you've found a scrap metal recycling facility near you, call them to ask if they accept Teflon-coated pans.
The healthiest cookware options are generally stainless steel, cast iron, ceramic, and glass, as they are durable, non-reactive, and don't leach harmful chemicals like PFAS or PFOA into food, even at high heat. For non-stick convenience without chemicals, high-quality ceramic-coated pans (derived from sand) are good, while uncoated cast iron and carbon steel offer excellent performance but require seasoning and special care, especially with acidic foods, to maintain their natural surfaces.
“If the nonstick pan has any chips or scratches, it should be thrown away,” says Breann Chai, who leads cookware testing at Consumer Reports. “The nonstick coating could be flaking off into any food being cooked in the pan, and you would want to avoid ingesting particles from the nonstick coating,” she says.
Old pans: "Older pans are not as safe as new ones because of the increased wear and tear, which removes the natural oxide protective coating, and the higher amount of scratches can increase the chances of aluminum leaching into food," Le says.
On average though, a high-quality ceramic pan used with proper care can last anywhere from 1 to 5 years. It may come as a surprise that ceramic pans have a shorter lifespan than other cookware types, such as stainless steel or cast iron.
Busy professional kitchens need pots and pans that can withstand years of heavy-duty use, meaning durable, uncoated metal items. It's just not practical or cost-effective from a business perspective to buy non-stick pans when that means frequently replacing them as they get damaged.
Constant exposure to high heat—both when cooking or in the dishwasher, neither of which we recommend—can cause your pan's non stick coating to degrade or even start to peel off. We advise sticking with medium heat or below to extend the lifespan of your non stick pan.
While stainless steel pans tend to be expensive, with the right care, they can last a lifetime!
As the studies conducted by the International Agency for Research on Cancer (IARC): the human body does not assimilate the particles, which remain utterly harmless. However, scratches can cause a reduction in the non-stick qualities of the utensil: so it is best to replace the product concerned.
If you notice that your baking pans are developing rust, the best decision would be to replace them with new ones. "The risk far outweighs the benefit of trying to recover the baking pan," Le says. Le adds that you could, in theory, rely on a phosphoric acid-based cleaner to remove the rust from your pan.
If the shape is warped, it's time to replace your cake pan. This could be dents or unevenness in the bottom of the pan or the sides. When your pan no longer retains its original shape, especially on the bottom of the pan, it can affect how evenly the pan bakes.
Some types of cookware — like aluminum and ceramic — are more likely to release metals into foods that are cooked in them. This is especially true if food is cooked for a long time, or if older pots are used. Stainless steel, glass, or cast iron cookware are less likely to release metals or chemicals into foods.
Don't cook or store food in scratched or worn anodized aluminum cookware. Use the cookware according to the manufacturer's intended use and instructions.
Whatever its coating, once your pan is scratched, distorted or cracked, it can no longer do its job properly, even though it will still be as safe to use. You should replace it as the coating will become less effective. If you can no longer use it without adding fat, it's time to replace it.
Signs It Is Time to Replace Your Nonstick Pans
Nontoxic and safe for cooking: First and foremost, stainless steel is celebrated for its nontoxic properties. Unlike some other materials that can leach chemicals into food when under high heat or when scratched, stainless steel is one of the safest cookware options on the market.
You should avoid non-stick pans with older PTFE/PFOA coatings, aluminum pans, unlined copper cookware, and chipped ceramic or enameled pans, as these can leach harmful chemicals like PFAS, aluminum, or heavy metals (lead, cadmium) into food, especially with acidic ingredients or high heat. Also, be cautious with "non-toxic" claims on new non-stick pans, and avoid vintage cookware or pans with flaking painted surfaces due to unknown materials.
If you've decided to swear off PTFE-coated nonstick cookware, there are several good alternatives, including ceramic, cast-iron, carbon steel, and stainless steel pans that perform well in our tests.
For the safest cookware in Australia, choose materials like stainless steel, cast iron, carbon steel, or ceramic-coated options to avoid harmful PFAS chemicals, with brands like Solidteknics (Australian-made) and GreenPan offering PFAS-free ceramic non-stick choices. The best choice depends on your needs: stainless steel offers durability, cast iron provides excellent heat retention (but requires seasoning), while ceramic non-stick is easy to clean, but ensure it's PFAS-free and replace if scratched.
