Shinny silver can be gently cleaned with a Silver Polish Cloth, taking care not to mark the plastic. The black oxidised silver cable has been treated with a chemical solution to produce the black finish. This finish can wear away over time particularly in exposed areas which adds to the character of the piece. If needed clean the oxidised silver by gently wiping with a soft damp cloth but avoid using silver dip or a silver cloth on the oxidised silver as this will remove the oxidisation. As with all jewellery avoid spraying with perfume and hairspray and do not immerse in water.
