Which common condiment is the best cleaner for copper pots and pans?

Ketchup is the best common condiment for cleaning copper pots and pans. The acidity in the ketchup helps to remove tarnish and grime from the copper, and the texture of the ketchup helps to scrub away any stubborn dirt. To clean a copper pot or pan with ketchup, simply apply a generous amount of ketchup to the surface of the pot or pan and rub it in with a soft cloth. Rinse the pot or pan thoroughly with warm water and dry it with a clean cloth. Your copper pots and pans will be shiny and new in no time!
