Do you use the ironsponge on stainless steel? I assume you mean something like steel wool?

My biggest "pro" for cast iron is that it's incredibly easy to clean without worrying about ruining the pan. Our stainless steel pan gets scratched if I look at it wrong, even using the rough side of the sponge. Not sure if we just have the wrong pan, or worry about scratches more than we should?

For our cast iron I use chainmail if there's every anything stuck on hard. For the stainless steel I feel a lot more out of luck! Metal utensils, soap, rough side of the sponge, I'm never worried about it!
