I bought these little things that are about the size of a sponge, but they have stiff netting on them with a metallic thread going through that. They clean the stainless pots and pans and the outside of all my pans really well.
The only thing I DON'T like about them is that metallic thread. I always microwave my sponges (according to CDC advise) but am afraid to put these in the mike.
