Cleaning:

Care of the black chrome is different to bright chrome plating. The black colouring is created by introducing oil to the plating. So you will find you get black hands when handling them. We find cleaning them with WD40 or GT85 puts oil back into them keeps them looking bright. They will go a smoky colour with use. The most important thing to not use an abrasive chrome polish on them. Wax polish or Mr Sheene type polish is perfect for them.
