It is the softest things in the world overcome the hardest things in the world."– Lao Tzu Suitable cleaning method: Please prepare lukewarm water and mild/neutral soap (cleaning solution). Gently clean the details of the surface with a soft-bristled toothbrush. Please remember to dry the jewelry completely after cleaning, or use a cold air blower to dry the jewelry on the towel (please do not use hot air) to prevent residual moisture from accelerating the oxidation of the metal.
