Brass bullet casing and brass jewelry care
Due to natural causes, brass pieces and bullet casings may tarnish over time because of oxygen and other factors. Avoid wearing jewelry in the shower, swimming, or in a hot tub to reduce tarnishing. Periodically clean your brass jewelry so it stays nice and shiny for your longtime wear.
To clean brass pieces
Most brass cleaners will work for the bullet casings and brass charms used in your jewelry; such as Nevr-Dull or Brasso. These can be found at most local hardware stores. Rub surface with cleaner and then wipe off with a clean paper towel. Natural cleaners can be made with the combination of vinegar, salt, and flour or, baking soda and white vinegar. Just give it a little "google".
*Make sure to follow directions on package and ALWAYS wash your hands after using cleaners*
