Solutions such as silver dip can be used. It is recommended that the solution be applied sparingly with an old toothbrush or cotton bud to silver areas only, ensuring it is rinsed and dried thoroughly afterwards; if the solution comes into contact with the enamel it may affect its surface. A standard silver cloth may also be used but please be aware that it will increase the shine on satin areas of silver.
