Maintenance of moist jade

1. Avoid collision with hard objects: jade pieces are easy to crack after collision. Sometimes, although the cracks are invisible to the naked eye, there are dark cracks on the jade surface, which greatly damages its perfection and economic value. Jade articles should avoid exposure to the sun. Prevent the texture and color of jade from being affected.

2, avoid chemicals: chemicals will bring certain damage to jade, such as various detergents, soaps, pesticides, cosmetics, perfumes, hairdressing agents, etc. If you accidentally touch it, wipe it clean in time to avoid damage to jade.

3. Try to avoid dust and oil stain: If there is dirt or oil stain attached to the jade surface, it should be scrubbed with light soapy water first, and then rinsed with clear water, and chemical degreasing agents cannot be used.
