How to clean the newly pasted rain flower stones?

First, the simplest method is to soak and clean with toilet cleaner (strong type) at home for a few days, then apply a little toothpaste and clean with a brush, so that a small amount of surface stone rust can be removed from the stone surface. If there is residual stone rust, you can gently polish it with oilstone.

Secondly, the stone rust with large area or large thickness on the stone surface is best soaked and cleaned with hydrochloric acid. But this method will have an impact on the quality of the stone. It is hoped that it is best to observe constantly in the process of soaking and washing, and master the pickling process in time to prevent excessive pickling. But this method is harmful to stone and stone color.

Third, it is safer to adjust the proportion of water with dilute hydrochloric acid (white fine particles are sold in chemical stores) according to the instructions, and then put the stones in. This method only needs a little observation and treatment when soaking stones. This dilute hydrochloric acid does not hurt hands or stones. It is estimated that the less tenacious stone rust can be removed in a day or two.

Fourth, if there is still stubborn stone rust after soaking and cleaning, you can gently grind off the residual stone rust with oilstone. Because the texture of stone rust treated with dilute hydrochloric acid has softened, it is easy to wear off. However, when polishing, we must master the depth of polishing, try to wear off the stone rust, and don't hurt the original stone skin.
