Some people may face to some problems about bathroom stone: being darker, serious damage and surface polish disappear. When these happen, you need to polish the surface. We can get some polishing compound in big construction material market. Polishing compound is combined by polishing powder and polishing solution. There is some small particle in polishing powder, and the main element of polishing solution is surfactant. Sometimes we can also polished by hand to deal with some small damage, while we use machine to polish some large area with damage and unpolished.

If it’s bathroom in your own house, you can clear it by yourself. You should spread the polishing compound on stone surface with some cotton cushion. You can get a good effect on that. If there is no specified cotton cushion，you can also use the nonwovens to polish, it can also make it gloss in some way. But don’t use crocus paper, because it will make some scratch and be more difficult to deal with.

If the bathroom is in hotel or other public places, you can do as below.

1) Try to make sure the surface is dry. Use neutral cleaner to clean the surface if needed.

2) Spill flourescer and polish powder to stone surface.

3) Use surface grinding machine or manual grinding machine with cotton cushion to polish until it turn back to flash.

4) Clean the surface with water and then scrape with cotton cloth.
