Pewter

I would like some advice on treatment of early twentieth century
pewter objects such as Liberty Tudric. These, a clock and a bowl
with coloured transparent enamel, are now dull and dark but were
presumably originally shiny. I further presume that they were
expected to be polished weekly by the maid until they disappeared.
How might they be shined AND preserved?
