What should I do with them now?
Hello I recently cleaned a set of quite tarnished silver plated silverware that I got from an old auntie so I scrubbed it a bit with bar keepers friend until the spots are gone but they look clean, then the next day I am using them in the kitchen and I put them in like a container of tap water and the next 30 mins to an hour 3 of them turned greenish with one of em having black spots, is it still ok to use them for plating and cooking etc?
