Rubbing with soft chamois and cloths after cleaning will give the metal the polish it often needs. Buffing and the use of pumice powders and pastes help along the better finishes. But these things all must be done in moderation to preserve the life of these metals. The more precious gold or silver must be treated of course with great care. Chemicals are dangerous and the best acids are lemon and those things which cannot poison. Many combinations are poisonous and must be used with discretion and the article well washed before using. Were the space allotted for this story greater we could take up many more things, but space being the rarest of commodities we shall have to end with one last admonition: When your devices do not work, as guaranteed, first look to yourself or assistant and see what is wrong. Then if you find you can absolve yourself from the great transgression--carelessness or ignorance--it will be time enough to attack the dealer and get redress.
