The polishing powder on the jadeite can be removed by:
1.*Wipe with a soft cloth**: Gently rubbing the surface of the jadeite with a soft cloth can remove most of the polishing powder. Be careful not to use too much force to avoid damaging the jadeite.
2.*Use a neutral detergent**: If the polishing powder is difficult to remove, you can use a neutral detergent, such as hand sanitizer or dish soap, and gently wipe the surface of the jadeite with a soft cloth. Then rinse with clean water and dry with a soft cloth.
3.*Use an ultrasonic cleaner**: An ultrasonic cleaner can shake off the polishing powder on the surface of the jadeite. Put the jadeite into the washing machine, add an appropriate amount of cleaning agent, start the machine, take out the jadeite after cleaning for a few minutes, and dry it with a soft cloth.
4.*Use sandpaper sanding**: If none of the above methods can remove the polishing powder, you can consider sanding with sandpaper. However, it should be noted that sandpaper grinding may cause some damage to the surface of the jadeite, so it should be operated with caution.
In the process of removing the polishing powder, care should be taken to protect the surface of the jadeite from scratches or damage. If there are obvious blemishes or cracks on the surface of the jadeite, it is best to consult a professional before removing the polishing powder.
In addition, in order to maintain the brightness and luster of the jadeite, it is recommended to maintain the jadeite regularly. A special jadeite care oil or olive oil can be applied to the surface and then gently wiped with a soft cloth to maintain its shine and color.
