Gold plated jewelry is prone to oxidation and fading. Although our product has advanced technology, thick coating, and is not easy to fade, reasonable use can still make the product color retention more durable Jewelry maintenance tips: 1. When wearing alloy jewelry, it should be removed and placed aside during bathing, washing face, or sweating in summer, as the acidity or alkalinity contained in the detergent or sweat can react with the alloy, causing corrosion and fading of the alloy. 2. When going to bed at night, jewelry should also be removed. Sometimes sweat may break out while sleeping, especially in summer. The coating on alloy jewelry will quickly oxidize and corrode when exposed to sweat for a long time. In addition, it is not advisable to wear the same accessory for a long time, and multiple accessories should be replaced frequently. 3. When doing rough work, accessories should be removed to avoid scratching them. 4. When alloy jewelry is not worn, it should be stored. Before storage, it should be wiped clean with a dry cloth to remove substances on the surface of the jewelry that are prone to oxidation. The jewelry should be sealed and stored in a sealed bag to isolate the air. 5. When collecting alloy jewelry, different accessories should be separated and not stacked to avoid rubbing against each other and scratching the surface. 6. When adjusting the size of the bracelet buckle or earring, do not forcefully pull and close the accessory to avoid deformation or breakage. When alloy jewelry loses its original luster, if you still want to wear the jewelry, you can go to a gold shop or other specialized place for jewelry maintenance to gild it, which can restore your jewelry to its former glory.
