Natures way to clean copper
I had to check this one in a dictionary: Rhubarb.
Again, like ketchup or lemons, it works with natural acids, and removes oxide from copper like magic.
Of course, it´s even easier to just leave the block in a bowl of Coke and rinse it afterwards, rhubarb takes a bit of elbow grease.
