Dawn and a sponge, let soak for a while in hot soapy water. Do you have a pot that is full of badly burned food?
I would use water and baking soda for a soak, then just wash as usual in soapy hot water, rinse, and dry.
Badly burned non-stick coatings flake off into one’s food and that’s not healthy.
If the surface is damaged, time to treat yourself to a healthy new pan.
Here is a really good trick I use, if your have tons of food left to the bottom of the pan and hard to get rid of. I would put some warm water and dawn soap plus add one dry sheet from the laundry room. Leave it for 30 minutes and after that just clean or wipe it off. It's that easy. And if your question is the bottom of the pan outside then use Bar keepers friend... the best product so far. I have long list on how to clean all these pots and pans...here you go with the link https://bushraslifestyle.com/the-28-top-rated-best-cookware-sets-buyers-guide/
