925 silver gold plated: Normally, if the 925 silver gold plated is worn correctly, it can be maintained for one year without fading. But suppose the 925 silver gold plated surface is stained with a lot of grease and sweat when wearing. In that case, the wearing time will be shortened, and the color will fade after about half a year or even earlier. We can maintain the 925 silver gold plated to delay its fading. In the maintenance of 925 silver gold plates, the surface of 925 silver gold plate can be wiped clean with a fine linen cloth or tissue paper with good water absorption performance to avoid the oil sweat staying too long, causing an impact on it. It can also clean the 925 silver gold plate by coating a layer of colorless and odorless nail polish on its surface and forming a protective film after drying to prevent the 925 silver gold plate from being eroded by foreign bodies and delay the fading.
Brass gold plated: Brass gold-plated jewelry can generally be worn for about three years. Time is easy to fade. During wearing, please pay attention to keep away from acidic and alkaline substances, including toner, soap, laundry detergent, and dishwashing liquid, to avoid accelerating its fading.
