Scratched Cookware: Safe Or Not?

Scratched pots and pans are a common occurrence in any kitchen, but are they safe to use? The answer is a little complicated. While tiny particles of the coating may chip off non-stick pans and end up in your food, the Food and Drug Administration (FDA) advises that these particles are not a health hazard and will simply pass through your body. However, some sources claim that scratched non-stick pans can release toxic compounds and that the coating can start to flake off into your food.

Non-stick pans can release toxic compounds when scratched

Non-stick pans are popular for their convenience and ease of cleaning. However, when they become scratched, the non-stick coating can flake off into food, potentially releasing toxic compounds.

The non-stick coating on pans is often made of PFAS (per- and polyfluoroalkyl substances), also known as "forever chemicals" due to their persistence in the environment. One common PFAS is polytetrafluoroethylene (PTFE), often known by the brand name Teflon.

Perfluorooctanoic acid (PFOA) is another PFAS that was previously used in the processing of Teflon. PFOA has been linked to cancer in lab animals. While most manufacturers have phased out the use of PFOA, it is still a concern for older pans.

When non-stick pans are scratched or chipped, small particles of the coating can flake off into food. A 2022 study found that scratched pans coated with PFAS released thousands to millions of microplastics and nanoplastics. These particles can be ingested, potentially exposing you to toxic chemicals.

Additionally, when non-stick pans are overheated, they can release fumes that may cause flu-like symptoms in humans and can be fatal to pet birds.

To minimise the risks associated with scratched non-stick pans, it is recommended to replace them regularly, especially if the coating is damaged or the pan is no longer non-stick. Proper use and care, such as using low to medium heat and avoiding abrasive cleaning methods, can also help prolong the life of non-stick pans.

Perfluorooctanoic acid (PFOA) in non-stick pans is linked to cancer

Perfluorooctanoic acid (PFOA) is a chemical that was originally used in the processing of Teflon, the coating responsible for the non-stick quality of some pots and pans. PFOA is part of a large group of lab-made chemicals known as per- and polyfluoroalkyl substances (PFAS). PFAS have been used since the 1940s to make non-stick coatings on cookware, as well as protective coatings for products like carpets and fabrics. They are also used in food packaging, firefighting foams, ski wax, and some other products.

PFOA has been linked to cancer in lab animals. Studies in lab animals have found that exposure to PFOA increases the risk of certain tumours of the liver, testicles, mammary glands (breasts), and pancreas. The International Agency for Research on Cancer (IARC), part of the World Health Organization (WHO), has classified PFOA as "carcinogenic to humans" (Group 1) based on sufficient evidence that it can cause cancer in lab animals and strong evidence that it has some of the key properties of a carcinogen in humans.

However, it's important to note that the Food and Drug Administration (FDA) advises that tiny particles of Teflon that may chip off into food due to scratches pose no health hazard as they simply pass through the body. Additionally, the Environment Protection Agency (EPA) reports that Teflon does not actually contain PFOA, so there is no health hazard from using it.

Furthermore, most manufacturers of non-stick pans have phased out the use of PFOA in their products. Even if you ingest small amounts of PFOA from using older pans, these amounts are insignificant and will not cause adverse health effects.

How to fix scratched non-stick pans

Non-stick pans are a great kitchen utensil that can make cooking and cleaning up a breeze. However, they are prone to scratching, which can affect their performance and appearance. While some people opt to throw away scratched non-stick pans, there are ways to fix them. Here is a detailed and direct guide on how to do so:

Step 1: Cleaning the Pan

First, ensure that you thoroughly clean your non-stick pan. Use lukewarm water and a soft sponge or cloth to remove any food residue or fat. Avoid using abrasive scouring pads, steel wool, or scrubbing pads, as these can further damage the non-stick coating. You can also use a mild dish soap to ensure that the pan is free of any grease or residue. Once cleaned, dry the pan with a soft cloth or paper towel, or leave it upside down on the counter to air dry.

Step 2: Apply a Repair Spray

Once the pan is dry, it's time to apply a non-stick cookware repair spray. These sprays are designed to fill in scratches and restore the non-stick surface. Coat the entire pan evenly with the spray. If you don't have access to a repair spray, you can try using a product like Bar Keeper's Friend, which is designed for cleaning non-stick surfaces.

Step 3: Let the Pan Sit

After applying the repair spray, let the pan sit for about 30 minutes at room temperature. It is recommended to cover the pan with cling wrap or tin foil to protect it from dust or other particles.

Step 4: Heat the Pan

The next step is to heat the pan to help the repair spray restore the non-stick surface. You can do this in an oven or on a stovetop. If using an oven, preheat it to 450 degrees Fahrenheit and bake the pan for 45 minutes. Ensure that the handles of the pan are oven-proof. If using a stovetop, place the pan over low to medium heat for 15-20 minutes.

Step 5: Wash the Pan

After heating, let the pan cool down, and then thoroughly wash it with lukewarm water and a mild dish soap. Be gentle and avoid using abrasive scrubbing pads or applying too much pressure. This step will remove any residue from the repair spray.

Additional Tips to Prevent Scratches:

• Use wooden, plastic, or silicone utensils instead of metal utensils to avoid scratching the non-stick surface.
• Avoid cooking at high temperatures, as non-stick pans are not designed for extreme heat.
• Never preheat an empty non-stick pan, as this can emit dangerous polymer fumes.
• Only hand wash non-stick pans with mild dish soap and warm water. Avoid using abrasive scrubbing pads and the dishwasher.

By following these steps, you can extend the lifespan of your non-stick pans and keep them performing at their best.

How to prevent scratches on non-stick pans

To prevent scratches on non-stick pans, it's important to be mindful of the utensils and cleaning tools you use. Avoid using metal utensils such as spoons and spatulas, as these can easily scratch the non-stick coating. Instead, opt for wooden, rubber, or silicone utensils. When stirring food, use a wooden spoon rather than a metal one.

It's also crucial to avoid using abrasive cleaning tools like steel wool or scouring pads when cleaning your non-stick pans. These can quickly cause scratches and damage the coating. Stick to soft sponges and cloths when washing your pans. Additionally, it's recommended to hand wash non-stick pans instead of putting them in the dishwasher, as the dishwasher's harsh conditions can increase the likelihood of scratches.

Another way to prevent scratches is to avoid stacking your pans on top of each other during storage. The bottoms of pans can often have rough surfaces that can scratch the non-stick coating when stacked. To prevent this, place a cloth towel or a layer of paper towels between each pan when stacking them.

It's also worth noting that non-stick pans should be used at low to medium heat settings. Using high heat can degrade the non-stick coating and make the pan more susceptible to scratches. Additionally, overheating non-stick pans can release fumes that may be harmful to humans and pets, especially birds.

By following these simple guidelines, you can effectively prevent scratches on your non-stick pans, prolonging their lifespan and maintaining their performance.

What to do with scratched non-stick pans

If your non-stick pans are scratched, it is generally recommended that you replace them, especially if they are older pans. This is because, with age, the non-stick coating can start to break down and release toxic compounds, which can then flake into your food. However, if you can't bear to part with your scratched pans, there are some things you can do to try and repair them.

Firstly, identify the scratched areas and assess the severity of the scratches. If they are only superficial, you can try a simple reconditioning method by applying a small amount of cooking oil to the scratched area and rubbing it in with a soft cloth. This can help rejuvenate the non-stick coating. Alternatively, you could try using a non-stick cookware repair spray, which will create a protective layer over the scratches.

If the scratches are deeper, you may need to try a different repair method. One option is to create a paste from baking soda and water and gently rub this into the scratches with a soft cloth or sponge. This can help to smooth out the surface. Make sure to thoroughly rinse and dry the pan after this process.

It's important to note that these repair methods may only provide a temporary solution, and the best course of action for scratched non-stick pans is often replacement. To prevent scratches in the future, use non-metallic utensils such as wooden or silicone spatulas, and avoid using abrasive cleaning pads or steel wool. You should also avoid stacking your pans to prevent scratches.
