1. 2g of edible salt, 7g of baking soda, 8g of bleaching powder and 60ml of clear water can be mixed together in a container. Put the gold jewelry into another small container, and then pour in the newly prepared "cleaning agent". After 2 hours, take out the gold jewelry, rinse it with clear water and dry it with a clean absorbent towel or soft cloth.
2. Silver ornaments are oxidized and blackened. You can dip a little toothpaste with a soft brush, gently wipe it, and finally dry it with cotton cloth; If there are diamonds and precious stones on the jewelry, you can dip a cotton swab in the mixture of toilet water and glycerin, scrub the precious stones and frames and keep them clean. If the items are expensive, you can go to the jewelry cleaning point and clean them with special cleaning liquid to avoid damaging the jewelry.
3. It is best not to wipe gold jewelry with salt and vinegar for more than one month, and don't wait until a black film appears on the surface. Wiping with toothpaste or scrubbing with hot rice soup can also make gold jewelry shine. Timely maintenance of jewelry can keep it bright.
