From Tarnished Copper To Untarnished Repo:
Cleaning up copper pots stained with tarnish seems to be a difficult job, but it is not so difficult. It is a simple process to get rid of the tarnish that doesn’t seem to go away no matter how much you scrub the copper pots with steel wool and liquid dishwasher soap. Take some vinegar or salt and use a rough-in-texture-sponge to apply the vinegar on the tarnished surface. As you keep rubbing, it would go away without and stubbornness and you will have clean, shiny pots once again. Also, your repute as a kitchen cleaner would increase and improve manifold!
