How to take care of my metal hair accessory?

To clean a metal accessory, spread a dash of baking soda on a clean cloth and gently rub the accessory to bring back its shine. Baking soda is harmless for hard stones and for your hands. If the surface is uneven, you may use an old toothbrush over the metal part.

Do not worry if the microfiber cloth blackens, it is a normal phenomenon. In any case, wash your hands carefully after cleaning your accessories.

This works for any silver, chrome, stainless steel,  aluminium or tin item, to get rid of stains and protect against oxidation.
