If the temperature is too high or too much oil is used when using the cast iron pan, this may lead to color spots or discoloration at the bottom of the pan. In addition, if rough cleaning tools are used when cleaning pots and pans, it may also cause damage to the bottom coating.

In order to protect your cast iron pan, it is recommended that you do not overheat when using it, and use warm water and mild detergent when cleaning it. If it is found that the coating on the bottom of the pot has been damaged, it is suggested to stop using it immediately and consider repainting the bottom of the pot.
