Substances like lemon are highly effective in cleaning copper vessels because of the citric acid present in them.
As soon as this acid comes in contact with the copper layer it dissolves the same, thereby bringing back the shine of the copper vessels.
Even tamarind is a good option as it results in neutralisation.
