How to maintain the rosary of Zionotan?

In daily life, because rosewood is in contact with the outside world by hand, after a long time, the surface of rosewood will appear black and bright, as if it were covered with something. That's the point. In fact, this paste is not the so-called patina. The real patina is that the surface of rosewood is a kind of transparent luster, which gives people the illusion that they can look into the wood. This is the real patina. Usually, we should pay attention to cleaning rosewood and clean it with clean cotton cloth, because this will make it more fully oxidized, so we must wait patiently, because the longer the oxidation takes, the more fully it will be, and the patina process is actually oxidation.
