Copper is a material that is constantly changing. It oxidizes and changes in both color and gloss. If you want to polish the copper surface so it becomes shiny, this remedy is unbeatably good.
Take some witch on a cloth and rub into the copper tubes, wipe afterwards with a clean cloth. See picture no. 2 for the difference in the result. The right part of the tube is plastered with the Witch.
