Non-stick pans are a popular choice for home cooks and professional chefs alike, thanks to their affordability, versatility, and non-stick properties. However, the non-stick coating on these pans is fragile and can easily be scratched by metal utensils, leading to health concerns as toxic micro-plastics may be released into food. While deep or severe scratches often mean the pan needs to be replaced, minor surface damage can be fixed at home. Here are some methods to restore the non-stick coating and extend the lifespan of your scratched pan.

What You'll Learn
Use a repair spray
If your non-stick pan is scratched, you can use a non-stick cookware repair spray to fix it. This will repair the non-stick surface with the help of heat. Firstly, wash the pan with soap and water, and dry it thoroughly with a towel. Leave it to air dry for a couple of hours to ensure all moisture has evaporated.
Next, shake the can of repair spray well and hold it 8-12 inches away from the surface of the pan. Spray the coating evenly across the entire surface of the pan, focusing on the scratched areas. Allow the repair spray to dry completely, which can take two hours or more.
After the repair spray has dried, you will need to cure the pan in the oven. Preheat your oven to 300-500 degrees Fahrenheit. Place the pan inside the oven, ensuring it is oven-safe and that any non-oven-safe features, such as handles, have been removed. Leave the pan in the oven for 15-45 minutes, depending on the instructions on the repair spray.
Once the specified time has passed, turn off the oven and leave the pan inside to cool down. This can take an hour or more. After curing, allow the pan to cool to room temperature before gently washing it with warm water and a soft sponge to remove any residue from the repair process.

Try vegetable oil
If you have a scratched non-stick pan, it is recommended to replace it, as DIY fixes may not be effective and could potentially damage the pan further. However, for minor scratches, re-seasoning or applying a thin layer of cooking oil may help improve the appearance and performance of the pan.
To re-season your pan with vegetable oil, start by cleaning the pan gently with warm water and a soft sponge or cloth. Avoid using steel wool, scouring pads, or abrasive brushes, as they can easily scratch and deteriorate the non-stick surface. Use mild or diluted dish soap to avoid wearing down the non-stick coating over time. Dry the pan with a clean cloth, ensuring it is completely dry before proceeding.
Place the clean, dry pan on the stovetop over medium heat for about 3 minutes. Then, add 2 tablespoons of vegetable oil to the pan, coating the bottom entirely. Heat the oil until it smokes, then let it cool completely. Wipe out any remaining oil, and your pan should now be re-seasoned and stick-free.
Before using the pan, it is recommended to conduct a mini test. Heat one tablespoon of oil in the pan over medium heat, crack an egg, and observe it cooking. If the egg sticks to the pan, the re-seasoning process may not have been successful, and you may need to repeat the steps or try a different method.

Use baking soda paste
Baking soda is a mild abrasive that can be used to remove scratches and stains from your non-stick pan. To use this method, start by making a paste out of baking soda and water. Apply the paste to the scratched area and gently scrub in a circular motion with a soft sponge or cloth. Ensure that you do not deepen the scratch. If the metal beneath the non-stick coating is exposed, it is best to replace the pan entirely.
After scrubbing, wash the pan gently with warm water and a soft sponge to remove any baking soda residue. Dry the pan with a clean cloth. This method may help to reduce the appearance of minor scratches and restore the non-stick qualities of your pan.
To further restore the non-stick coating, place the clean, dry pan on the stovetop over low heat. Heat the pan at a gentle setting of 300°F to ensure no additional damage is done to the pan. Then, coat the pan with unsalted vegetable oil, ensuring the entire bottom of the pan is covered. Depending on the size of the pan, the oil should be at least half an inch high.
Finally, place the pan in the oven and heat it for about two hours. This will allow the vegetable oil to bake into and coat the bottom of the pan, covering the scratches. This process will help to fill in the scratches and create a smoother surface.

Parchment paper
If your non-stick pan is scratched, exposing the aluminium base, it is time to replace it. However, if the scratches are minor, you can use parchment paper (or baking paper) as a temporary solution to prevent food from sticking to the pan's surface.
To use this method, cut out a circle of parchment paper that fits the inside base of your pan. You can also cut the paper to the size of the food you are cooking, which should be slightly smaller than your pan. For example, a popular trend is to cut the paper to the size of a salmon fillet, season the fish, and cook it skin-side down on the parchment paper. This method will give you a crispy skin without the need for a non-stick pan.
Other methods to fix a scratched non-stick pan include using a cookware repair spray or completely removing the non-stick coating. The repair spray method involves cleaning the pan, spraying it with the product, and baking it in the oven for about 40 minutes. On the other hand, removing the non-stick coating will expose the aluminium base, which is not ideal for cooking, especially with acidic foods.

When to replace
Non-stick pans are convenient, but they do have a limited lifespan. While there are ways to repair a scratched non-stick pan, there are times when it's best to simply replace it.
Firstly, it's important to consider the age of your non-stick pan. Generally, non-stick pans should be replaced every five years. If your pan is older than five years, it's probably time for a new one. Pans made before 2015 are especially concerning, as they may contain PFOA, which has been linked to health issues. Even if your older pan doesn't contain PFOA, it's still wise to replace it.
Secondly, the depth of the scratches on your pan is crucial. Deep scratches or a flaking coating are a sign that your pan needs to be replaced. When the coating is compromised, it can start to flake off and mix with your food. This can expose the base material of the pan, often aluminium or another metal, which can affect the quality of your food, lead to uneven cooking, and even release toxic fumes if overheated. Minor scratches may not pose an immediate health risk, but deeper gouges can be more concerning.
Thirdly, if your non-stick pan is no longer non-stick and food starts sticking frequently, it's time for a replacement. This indicates that the coating has worn out and is no longer serving its purpose. Additionally, if your pan emits unusual smells or has a discoloured surface, it should be replaced for safety reasons. Discolouration, especially deep, dark spots, indicates that the coating is wearing out and can be a sign that the pan's surface has been damaged by overheating.
Finally, if you're unsure, it's always better to be safe than sorry. Non-stick pans are delicate and can easily be scratched by metal utensils, improper storage, or abrasive cleaning tools. Even small scratches can compromise the surface over time and release millions of toxic microplastic particles into your food. If you're concerned about the scratches on your pan, it's best to err on the side of caution and invest in a new one, especially if it's an older model.

Frequently asked questions
Deep or severe scratches that expose the underlying metal usually mean the pan has reached the end of its lifespan and needs to be replaced. If the coating is peeling, it's best to replace the pan for safety reasons and to avoid exposure to toxic chemicals.
First, clean the pan with warm water, mild dish soap, and a soft sponge to remove any cooking residue. Dry the pan thoroughly with a soft towel or paper towel. If the scratches are superficial, you can use a non-stick cookware repair spray to create a protective layer over the scratches. Alternatively, you can use a home remedy such as baking soda paste or vegetable oil.
Wash the pan with soap and water, then dry it thoroughly. Apply the non-stick cookware repair spray evenly to the entire surface of the pan and let it dry for about 30 minutes. Preheat your oven to 500 degrees Fahrenheit and place the pan inside for 45 minutes. Remove the pan and let it cool completely before using it again.
Avoid using metal utensils with non-stick pans as they can easily scratch the surface. Do not overload your pan with food or stack other pans on top of it as this can also cause scratches. Wash your pan by hand with mild dish soap and avoid putting it in the dishwasher.
You can try using vegetable oil to coat the bottom of the pan and leaving it overnight to cool and dry. This helps restore the non-stick properties of the pan. Another alternative is to use parchment paper or baking paper cut to the size of the pan's base.
