◉ Keep your pendant in a dry dark place, and try to avoid contact with household chemicals and aggressive chemical environment (remove when painting hair, etc.).
◉ To maintain patina contrast, it is not recommended to use aggressive methods for cleaning jewelry (boiling in chemicals, using acids), since there is a risk of damaging some natural stones and minerals, and completely removing patina from the metal.
◉
Copper gets darken with time. To return the original shine, simply wipe the convex sections on your necklace (in case of severe darkening it is permissible to apply a little toothpaste on a dry cloth), and then rinse the product with water and wipe it with a soft textile
.
◉ You can use old toothbrush and liquid dishwasher (like Fairy for example) to clean your necklace
