Brighten copper pans or ornaments
If your copper items are looking a little bit dull from oxidising, you can fix that in a flash.
Start by dipping half a lemon into salt, baking soda or baking powder, then rub it over the surface.
The lemon’s acidic properties dissolves the tarnish, and the salt, bicarbonate of soda or baking powder act as a mild abrasive to clear it away.
Rinse with water and dry with a cloth or a paper towel.
