Nonstick pans have become a kitchen staple, offering convenience and ease of cooking and cleaning. However, one common mistake that can cut short the lifespan of these pans is using cooking spray. Cooking sprays, such as PAM or Smart Balance, are marketed as a convenient way to prevent food from sticking to pans. While this may be true for traditional pans, cooking sprays can ruin the nonstick coating on nonstick pans. This is because, in addition to oil, cooking sprays contain lecithin, an emulsifier, and propellants like propane or butane. Over time, the lecithin and propellants in the cooking spray build up on the pan's surface, causing food to stick and compromising the nonstick coating. This buildup can be difficult to remove, even with vigorous scrubbing and soaking. Therefore, it is recommended to avoid using cooking sprays on nonstick pans and instead opt for alternatives like butter, margarine, or oils with high smoke points, such as avocado, canola, or grapeseed oil.

What You'll Learn
Cooking spray damages the non-stick coating of non-stick pans
Cooking spray can indeed damage the non-stick coating of non-stick pans, and it is recommended that you avoid using it on this type of cookware. Non-stick cooking sprays contain lecithin, an emulsifier, as well as propellants and additives. When applied to a heated pan, these sprays leave a sticky residue that adheres to the non-stick surface and is difficult to remove with regular washing-up methods. This residue builds up over time, compromising the non-stick coating's integrity and reducing its non-stick properties. This can cause food to stick to the pan, defeating the purpose of the non-stick surface and requiring you to scrub the pan harder during cleaning, which can further damage the coating.
The propellants and additives in non-stick cooking sprays can also break down at high temperatures, depositing more residue and further impacting the non-stick coating. This can also result in the release of potentially harmful particles and fumes during cooking. Non-stick pans are designed to distribute heat evenly and release food without the need for added fats or oils, and the use of non-stick spray interferes with this process, leading to uneven cooking and browning.
Instead of using non-stick cooking spray, you can try healthier and pan-friendly alternatives such as butter, margarine, or oils with high smoke points, such as avocado, canola, or grapeseed oil. For cooking at higher temperatures, clarified butter (ghee) is an excellent choice as it has a high smoke point and offers the flavour of butter without the risk of burning. You can also season your non-stick pans before their first use and a few times a year after that by rubbing a little cooking oil into the surface and placing the pan over medium heat for a couple of minutes.

Cooking spray leaves a sticky residue that is hard to remove
Cooking spray is a popular kitchen staple, offering a convenient way to prevent food from sticking to pans without the added calories of oil or butter. However, using cooking spray on non-stick pans can lead to a sticky residue that is challenging to remove. This residue is caused by the buildup of ingredients in the spray, such as lecithin, an emulsifier, and propellants like propane or butane.
Over time, this buildup can adhere to the non-stick surface, becoming increasingly difficult to remove with regular soap and water. The residue can impair the pan's performance, causing food to stick and affecting heat distribution, leading to uneven cooking. The residue can also break down the non-stick coating, reducing the pan's lifespan.
To avoid the sticky residue, it is recommended to use alternatives such as butter, margarine, or oils with high smoke points, applied with a pastry brush or paper towel for a thin, even coating. These alternatives provide a natural non-stick layer without damaging the pan's surface.
If your pan already has sticky residue from cooking spray, there are a few methods to try and remove it. Some people suggest using a powder cleaner like Bar Keeper's Friend or a combination of dish soap, baking soda, and steel wool. Others recommend simply soaking the pan or pouring boiling water into it to clear the residue. However, it may be challenging to restore the pan to its original condition, and the residue may persist.
To prevent this issue in the future, you can consider making your own natural cooking spray with olive oil and distilled water. This homemade spray eliminates the harsh propellants and additives found in store-bought cooking sprays, reducing the risk of residue buildup and protecting your non-stick pans.

Cooking spray can cause the release of harmful particles and fumes
Cooking sprays are convenient and assure that food won't stick to the pan. However, they can cause the release of harmful particles and fumes. This is due to the ingredients in cooking sprays, which can include oils, lecithin, dimethyl silicone, and propellants such as propane, butane, isobutane, nitrous oxide, and carbon dioxide.
The propellants and additives in cooking sprays can break down the coating of nonstick pans, shortening their lifespan. This can lead to the release of potentially harmful particles and fumes during cooking, especially if the pan is heated beyond the recommended temperature. The use of cooking sprays can also interfere with the cooking process, causing uneven cooking and browning.
The specific toxins present in cooking sprays depend on the brand and ingredients used. Some common toxins include propane and butane, which are flammable gases, and nitrous oxide, a greenhouse gas that contributes to human-caused climate change. While the small amount of these toxins in cooking sprays may not be harmful, cumulative exposure to them may pose risks.
To avoid the potential risks associated with cooking sprays, alternatives such as butter, margarine, or oils with high smoke points, like avocado, canola, or grapeseed oil, can be used. These alternatives can be applied with a pastry brush or paper towel to create a thin, even coating on the pan.

Non-stick pans are not designed for high heat
Cooking spray can ruin non-stick pans, but that's not the only way. Non-stick pans are not designed for high heat, and using them at high temperatures can damage the coating and cause the release of harmful toxins.
Non-stick pans are designed for low to medium heat. The coating on a non-stick pan will degrade over time if exposed to high temperatures, especially when mixed with oil. This is because some oils, like olive oil, have a low burn temperature. If you crank up the heat, the oil can polymerize and fuse to your pan in a thick, sticky layer that can destroy its functionality. Therefore, it is recommended that you avoid heating an empty non-stick pan, as this can damage the surface and its non-stick properties.
If you want to sear or fry foods, it is best to use a stainless steel or cast iron pan instead of a non-stick pan. Non-stick pans are perfect for scrambling eggs and sautéing delicate cuts of fish, but they require more care and attention than you might think.
To help your non-stick pan last longer, it is recommended that you season it before its first use and then a few times a year after that. To do this, rub a little cooking oil into the surface and place the pan over medium heat for a couple of minutes. You should also only use silicone or wooden utensils when cooking with a non-stick pan, as metal utensils can scratch off the non-stick coating.

Use oils with high smoke points for high-temperature cooking
Nonstick cooking sprays can ruin nonstick pans. The ingredients in these sprays, especially the propellants and additives, can be harsh on the surface of nonstick pans. With regular use, they can start breaking down the coating, shortening the life of the pan and impairing its nonstick release system. This can cause food to stick to the pan and affect the pan's performance.
To avoid this, it is recommended to use oils with high smoke points for high-temperature cooking. The smoke point of an oil is the maximum temperature it can reach before it starts to smoke visibly. Heating an oil past its smoke point can ruin the flavor of your dish and trigger smoke alarms. More importantly, it can also create harmful compounds in your food that can negatively affect your health.
When choosing an oil for high-temperature cooking, it is important to select one with a smoke point above 400°F (204°C). Oils with high smoke points include:
- Avocado oil (refined): 480-520°F (249-271°C)
- Canola oil: 400-475°F (204-246°C)
- Grapeseed oil: 420°F (216°C)
- Safflower oil: 475-500°F (246-260°C)
- Macadamia oil: 413°F (212°C)
These oils can be applied with a pastry brush or paper towel to create a thin, even coating on your pan.
