The cleaning methods for flat-bottomed pans are as follows:
· If the dirt on the flat-bottomed pan is shallow, such as oil stains or food residues, you can use a soft cloth dipped in a little detergent, wipe the bottom of the pan, and then rinse it with water1.
· If the dirt on the flat-bottomed pan is normal, such as the bottom of the pan is black or there are some stubborn grease stains, you can use a mixture of vinegar and salt, soak the bottom of the pan, and then use a scouring pad or steel wool to scrub23.
· If the dirt on the flat-bottomed pan is heavy, such as the bottom of the pan has uneven black dirt, you can use a professional pot bottom black dirt remover, and clean it with steel wool, remember to wear gloves to avoid irritating the skin4.
If you are worried that the coating of the flat-bottomed pan is broken, you can first check whether the coating has signs of damage or falling off, such as scratches, bubbles, cracks, etc. If the coating is intact, you can continue to use the flat-bottomed pan, but pay attention to the following points:
· Avoid using sharp tools to scrape the coating in the pot, which may cause scratches and damage. Choose wooden or silicone utensils, which can better protect the coating.
· Avoid high-temperature cooking, because high temperature may have an impact on the coating. It is recommended to use moderate temperature cooking and avoid overheating.
· Clean the flat-bottomed pan in time after use, and avoid the damage of residual food to the coating. You can use a soft brush or cloth dipped in neutral detergent to scrub, and never use a metal brush to clean, so as not to scratch the coating.
If the coating is damaged or fallen off, it is recommended that you do not continue to use the flat-bottomed pan, because this may have the following hazards:
· The purpose of the coating is to prevent food from directly contacting the surface of the container, thereby reducing possible pollution and cross-infection. And when the coating starts to fall off, the surface of the container will have exposed parts. This means that food comes into contact with the exposed surface of the container, which may increase the risk of food poisoning and health problems.
· The coating usually also has anti-rust and anti-corrosion functions, and its falling off may cause damage and faster aging of the container itself. In addition, if the container has potential bacteria or mold, the falling coating may become a breeding ground for them, further affecting the safety of food.
· If the coating is a non-stick coating containing harmful chemicals, such as PFOA (perfluorooctanoic acid), then the damaged coating may release toxic gases or particles. These chemicals may enter the food and cause harm to human health. PFOA is considered a potential carcinogen, and may also cause other health problems, such as liver damage, endocrine disorders, immune system depression, etc.
Therefore, for the sake of your and your family’s health, if the flat-bottomed pan coating is broken, it is best not to use it, but to replace it with a new one in time.
