"Fly true" salt water etched with arrows into a 1 1/2” solid copper pendant on a 24” copper rolo chain. Whatever your intent, let it hit the mark. Or maybe you like archery. In which case, it is extra important that it fly true because no one likes accidentally getting shot in the bum.
For regular maintenance and to keep your piece clean, use a soft cotton or microfiber cloth to lightly polish it.
Over time your piece will naturally oxidize. To clean excessive oxidation, use a pinch of salt and some lemon juice on a Q-Tip and lightly buff. Rinse with warm water and pat dry.
To further oxidize your piece naturally, store it openly in a room that has high humidity, such as a bathroom or kitchen. This will speed up the natural oxidation process.
