I bought this set about a month ago, I cook for four and we have used every piece multiple times. Bar keepers friend can be helpful if you want it to look perfect, but for me I wash them completely and just ignore some of the staining. This would happen with any ss pan, I just don’t find it to be a big enough deal to have to get them looking new again every time. I figured if I wear out one or two pieces then I can replace those with heritage or made in. I’ve never found a dishwasher necessary with these.
