Non-Stick Pans: Why They're Sticking And How To Fix It

Calphalon is a popular cookware brand known for its non-stick pans. However, some users have reported issues with their Calphalon pans sticking, even after the first use. While Calphalon pans are hard-anodized and designed to be scratch, corrosion, and abrasion-resistant, they can still become sticky if not properly cared for and maintained. Overheating can weaken the non-stick layer, leading to sticking. Additionally, using metal utensils can scratch the surface, peeling away the non-stick coating. To prevent sticking, it is recommended to avoid overheating, use wooden or plastic utensils, and hand wash with a soft sponge and lukewarm water.

Overheating weakens the non-stick layer

Overheating can indeed weaken the non-stick layer of a pan, and this is true for most non-stick pans, including Caphalon pans. Non-stick pans are usually coated with polytetrafluoroethylene (PTFE), also known as Teflon. When a non-stick pan is overheated, the PTFE coating starts to break down and release toxic fumes. This process is called pyrolysis, and it can start at temperatures as low as 260°C (500°F). During pyrolysis, the fluorine compounds in PTFE are released as volatile fumes, which are harmful to humans and fatal to birds.

The effects of overheating a non-stick pan can be rapid and dramatic. In as little as a single use, the non-stick properties of the pan can be severely compromised. The pan may appear unchanged visually, but its non-stick surface will be damaged and less effective. The coating may also appear "dry" or "matte" after overheating.

The release of toxic fumes during pyrolysis can pose serious health risks. At temperatures above 349°C (660°F), the coating breaks down more rapidly, emitting harmful fumes that can cause polymer fever in humans, characterised by chills, headaches, and high fever. Additionally, at temperatures of 360°C (680°F) and above, Teflon emits at least six different toxic gases, two of which are known carcinogens. While the amount of emitted gases may be relatively small, the potential health risks are significant.

To prevent overheating and minimise the risks associated with non-stick pans, it is recommended to follow certain precautions. Firstly, avoid heating the pan when it is empty, as this can lead to rapid overheating. Secondly, avoid cooking at high temperatures and opt for low or medium heat settings. Thirdly, ensure proper ventilation during cooking by using a hood or opening windows. Fourthly, avoid frying meat in non-stick pans, as it typically requires higher temperatures that exceed the safe limits for Teflon. Finally, choose heavier non-stick pans, as they are less likely to overheat and are generally safer.

Use of metal utensils

Using metal utensils on non-stick pans can cause the non-stick coating to wear off, resulting in food sticking to the pan. While some pans are advertised as "metal utensil safe", such as the ONYX COOKWARE™ Hybrid Non-Stick pan, using metal utensils on any type of non-stick pan is generally not recommended.

The non-stick coating on a pan is designed to provide a smooth surface that prevents food from sticking. However, this coating can be damaged by sharp edges and abrasive surfaces, such as those found on metal utensils. Over time, scratches and gouges caused by metal utensils can cause the non-stick coating to flake off, exposing the base metal of the pan. Not only does this compromise the non-stick properties of the pan, but it can also result in the release of potentially harmful particles into your food.

To maintain the integrity of your non-stick pans, it is advisable to use utensils made from softer materials, such as wood, bamboo, silicone, or nylon. These materials are less likely to scratch or damage the non-stick surface, ensuring that your pans remain in good condition for longer.

Additionally, it is important to properly care for your non-stick pans by avoiding harsh cleaning methods and metal scouring pads, which can also damage the coating. Hand washing with mild soap and a soft sponge is generally recommended, as dishwashers may be too abrasive for non-stick cookware.

By taking these precautions, you can extend the lifespan of your non-stick pans and ensure that your cooking experiences are safe and enjoyable.

Use of cold water and a stiff sponge

To clean your Caphalon non-stick pan, it is important to use cold water and a stiff sponge. Firstly, fill the pan with cold water and bring it to a boil for 5 to 10 minutes. This will help to loosen any stuck-on food particles. After boiling, dump the water and fill the pan with cold water again. Use a stiff sponge to scrub away any remaining food particles. If necessary, you can add a mild liquid dish soap to the sponge to help with the cleaning process. It is important to avoid using steel wool or metallic brushes as these can damage the non-stick coating.

For more difficult stains, you can create a mixture of equal parts water and vinegar, and bring this to a boil in the pan for approximately 10 minutes. The vinegar will help to break down the burnt-on residue. You can then dump the water and vinegar mixture and wash the pan with soap and cold water, using a stiff sponge to remove any remaining residue.

It is important to note that non-stick pans should not be exposed to temperatures much above 400 degrees Fahrenheit. Using high heat can damage the non-stick coating and cause it to peel off. If your pan has been exposed to high heat and the coating is peeling off, it is recommended to replace the pan.

Additionally, it is recommended to hand wash non-stick pans instead of using a dishwasher. This will help to preserve the finish and luster of the pan. Always allow the pan to cool down before washing it and avoid using cold water as it can cause warping or weakening of the pan.

Non-stick coatings aren't permanent

Non-stick coatings, such as polytetrafluoroethylene (PTFE), commonly known as Teflon, are engineered to reduce the ability of other materials to stick to them. PTFE has a very low coefficient of friction, which means that most substances, such as food, won't stick to it and can be easily removed from the cooking surface.

However, there are several factors that can contribute to the degradation of non-stick coatings over time. One of the main factors is overheating. PTFE-based coatings will rapidly lose their non-stick properties if overheated beyond approximately 260°C (500°F). At this temperature, the coating begins to dissociate, releasing toxic chemicals. Therefore, it is important to follow the manufacturer's recommendations and keep the temperature below the specified limit.

Another factor that can affect the durability of non-stick coatings is the use of metal utensils. If utensils that are harder than the coating are used, they can scratch and damage the surface. This can be prevented by using non-metallic utensils, such as those made of plastic or wood.

Additionally, the quality of the non-stick coating itself plays a role in its durability. Better-quality coatings tend to be more durable and less likely to peel, flake, and lose their non-stick properties over time. The number of layers of coating and the quality of the material used also contribute to the overall durability of the non-stick coating.

While modern non-stick coatings have improved significantly and can last for decades, they are still susceptible to wear and tear over extended periods of use. Therefore, it is important to properly care for and maintain non-stick cookware to prolong its non-stick properties. This includes avoiding overheating, using appropriate utensils, and following the manufacturer's care instructions.

Non-stick pans can be replaced with carbon steel

Non-stick pans are a popular choice for home cooks, but carbon steel pans are a great alternative. Carbon steel is made from 99% iron and 1% carbon, giving it a similar composition to cast iron but with a lighter, less brittle, and smoother finish. It is a superior heat conductor to non-stick pans, able to withstand higher temperatures and retain heat more effectively.

Carbon steel pans are naturally non-stick when seasoned. This is done by heating a small amount of high smoke-point oil in the pan, which fills in the small pores of the metal surface. The oil dries out and becomes a slick polymer coating bonded to the pan's surface, also known as polymerization. This process can be repeated as needed to maintain the non-stick surface.

Carbon steel pans are ideal for high-heat cooking, such as searing steak or charring vegetables. They can withstand temperatures up to 1200°F (649°C) and are suitable for use on induction cooktops, grills, and even over an open fire. They are highly durable and can last a lifetime if properly cared for. However, they do require some maintenance to retain their seasoning, and acidic foods can strip the seasoning over time.

Non-stick pans, on the other hand, typically feature a base of aluminum or stainless steel with a durable non-stick coating. They are perfect for cooking delicate foods like fish and eggs, as well as sautéing vegetables. Non-stick pans are easier to care for and can be washed with dish soap and a soft sponge. However, they have a shorter lifespan than carbon steel pans and require hand washing to avoid damaging the coating.

Both types of pans have their unique advantages, and they can complement each other in a well-stocked kitchen. Carbon steel pans are ideal for high-heat cooking and offer superior durability, while non-stick pans excel at delicate cooking tasks and provide a long-lasting, easy-to-clean surface.
