Why Your Non-Stick Pan May Be Wearing Out Faster Than It Should, and How To Fix It

In situations where food adheres to non-stick cookware, it becomes very tempting to scrub the pan vigorously. Scrubbing appears to make sense, and many people are of the view that exerting pressure when cleaning makes a non-stick pan cleaner. However, scientific studies have shown that vigorous scrubbing can be detrimental to a non-stick pan.

Aggressive cleaning of non-stick cookware has been linked to the degradation of the thin coating on these pans, making them lose their efficiency and effectiveness. As soon as the surface of non-stick cookware is scratched, there will be a higher tendency for food to adhere to the pan. Moreover, cleaning the pan will become difficult, and the pan will become ineffective even earlier than anticipated.

A study conducted by the Tribology International Journal indicates that microscopic abrasion of non-stick cookware can cause food to adhere to the pan more readily. The research showed that the problem is more prevalent in ceramic-coated pans since the coating wears off more quickly than anticipated.

Not all non-stick coatings perform the same

Fluoropolymer coating, such as PTFE or Teflon, is a type of non-stick cooking pan coating that can be found in many kitchens across America. According to the same paper from Tribology International, fluoropolymer coatings, including PTFE and PFA, maintained higher non-stick effectiveness over time compared to ceramic coatings. This was due to low force exertion by food upon these coatings, despite multiple usage occasions.

It should be mentioned that ceramic coatings might attract customers' attention since they are promoted as durable and heat-resistant materials, yet the non-stick property might decrease relatively quickly. This happens due to a higher increase in sticking with wear in case of ceramic coatings, since microdamage leads to the formation of uneven surfaces where the food sticks. Scrubbing becomes necessary, causing more wear.

The cycle described above tends to make a pan less useful faster.

Why abrasive scrubbing causes damage

A seemingly benign scrubbing process can lead to wear on a microscopic scale. Steel wool, harsh scrub brushes, and even heavy scrubbing using common sponges can lead to the wearing down of protective coatings. As noted in Tribology International, the abrasion process impacts surfaces such that adhesion and separation become more difficult.

The problem is not just about visible scratching; many issues start out as microscopic abrasions. According to specialists, microscopic abrasions can impact both the chemical composition and surface texture of coatings, leading to a reduction in the smoothness that enables foods to easily slip off.

This is why cleaning techniques are just as important as cooking practices.

Heat can damage coatings, too

However, this is not the end of the issue. High temperatures can also cause rapid wear of the coating. Another research conducted by scientists and published in Heliyon proved that the temperatures exceeding 250 degrees Celsius, which is around 482 degrees Fahrenheit, can increase wear for cookware coated with either PTFE or ceramic coatings.

Scientists revealed that overheating can negatively affect the quality of coatings and make them rough, making them less non-stick in nature. When it comes to pans coated with PTFE, specialists have always recommended using medium or medium-high heat, as it was believed to help save the coating.

How to clean a non-stick pan safely

According to experts, there are gentler ways of cleaning a pan compared to what most individuals do. A sponge, warm water, and a little amount of dish soap are sufficient for regular cleaning. Cleaning the pan immediately after cooling may help to avoid residues drying up on the pan.

Soaking works better than scrubbing when dealing with food that adheres strongly to the pan. Authors of the study published in Tribology International emphasize that minimizing abrasive wear is important in order to retain coating integrity, especially when talking about ceramic pans that may be prone to abrasions.

It is important for some cooks to refrain from using metal utensils and harsh detergents.

Why gentler care can make pans last longer

A lot of folks change their non-stick pans sooner than needed. It seems that a proper care routine might considerably increase their serviceability. It was established that the non-stick cookware that is coated with fluoropolymers can withstand even normal use when it comes to being treated gently and not overheated.

This means one thing only. The harder you scrub, the worse off the pan gets. Some cases require not additional effort, but quite the opposite. Though scrubbing hard may help deal with the sticky foods, it is proven to be one of the main contributors to making the pan less functional over time.

Considering its frequent use, treating it gently might be just the thing to make a difference.
