How to Clean Copper with Lemon juice dip?

Squeeze the juice of one or two lemons into a cup and add some salt into it. Place the copper jewelry into the lemon juice and leave it for several minutes. If necessary, use a soft brush or cloth to rub the lemon to get rid of all the tarnihs. Rinse with water thoroughly and dry your copper jewelry. Don’t use metal containers for this method. Always use glass, ceramic or plastic.
