If you like bright brass, you can use the copper oil purchased by hardware, polish it and then wash it with detergent. * When the silverware is not worn, it can be stored in a sealed bag to reduce oxidation and avoid contact with hot springs and the like. * The body's oil can be warm and lustrous. It is a natural protection to wear. However, if the human body's sweat or water vapor is dirty, it may oxidize the silver. If it is slightly oxidized, it can be used in kitchen foil + salt + hot water. The gloss can be restored or simply cleaned with a silver cloth. * Do not use silver washing water, which will make it more difficult to clean in the future. If it is severely oxidized, it can be returned to the maintenance. We provide life-long cleaning and maintenance service. You only need to pay the return shipping cost. If the damage is repaired, it will be quoted separately. **[shipment instructions]** Order order, please tell us your hand and the content you want to type, you can type numbers and uppercase English letters, including spaces up to 30 words, 3~5 working days after receiving the order. **[other instructions]** The picture may have a color difference, which is subject to the actual product.
