The specific reasons and solutions are as follows:
1. The steamer pad selected is not food-grade silica gel, and the material is doped with other substances, resulting in food adhesion. Pay attention to whether the silicone material of the steamer pad is food grade when buying.
2. The bottom of the steamer pad is not cleaned, and there is floating ash on it, which leads to adhesion. Pay attention to cleaning before use, and ensure that the floating dust on the steamer pad is cleaned before use.
3. Improper operation during use or storage. Pay attention to cleaning after use and store the steamer mat in a clean and dry place.
