Nice find, I clean all my artifacts by rinsing them under warm water and lightly scrubbing them with an old tooth brush, sometimes even adding a dab of dish soap will help remove that caked on dirt. If there is corrosion on say a brass general service eagle button, I?ll let the artifact soak in hydrogen peroxide for around 10 minutes depending on how bad the corrosion is. Then again going back and brushing it with the tooth brush or using something wooden such as a chopstick, try knocking off the corrosion. The peroxide helps loosen up that hard dirt and corrosion, just wear some latex gloves or you?ll bleach your finger tips! Once you?ve got her clean, rub her down with some olive oil and you?re good to go!
