Aide brand electric pressure cooker, stainless steel pot used it for less than a month, and found that there was blue light in the cooker. What happened?
No problem, we can experiment. When you put the blade on it or on it, it will turn blue when it burns. This should be a characteristic of steel's reaction to temperature. There is no problem with food safety. Or you can wipe it hard with a wet paper towel or alcohol or oil to see if it can be removed. Or wipe hard with a dry towel after getting wet. ,,,, No problem. Feel free to use. Stainless steel lining without coating
