Reader Chris gave us this tip for keeping the copper bottoms clean:
Heat Campbell’s tomato soup in pan. Before washing, rub left over soup on the copper and let sit a few minutes. If one eats the soup every few weeks the copper looks better and better with almost no labor.
I love polishing the copper bottoms of my vintage Revere Ware.
It both relaxes and pleases me.
I read years ago, that heat is conducted better when they are not sparkly, shiny, coppery new looking. I don’t do it as often, also no longer have a hanging pot rack.
