What is a good way to clean brass without buying a commercial cleaner?
Most commonly used kitchen cupboard or refrigerator ingredients that
contain a natural acid, such as vinegar, Tobasco Sauce, ketchup, tomatoes,
milk, and lemon or lime juice, will remove tarnish. The tarnish washes away
with an acid rub or soak. You might have to remove the lacquer cover if the
brass is new. Do this by submerging the brass in boiling water with a few
teaspoons each baking soda and washing soda (available in the laundry section
of the supermarket). Once the lacquer has peeled off, polish dry.
