Perfectly adequate for everyday cleaning of pans and dishes etc. Can be re-used time and time again as they are quite tough and last well. I would not say that they would be good for VERY hardened on pan marks/grease but are ideal for general cleaning purposes and can also be used for cleaning many things e.g. pot sinks, stainless steel sinks, glass, tiles, loo's, cups, plates, etc. as they do not scratch.
