Meanwhile, granite mineral component in more complex, especially in light of iron components in granite, often rust in wet conditions, and on the surface of the stone, is block yellow spot. So, how to remove granite by the pollution and disease?
1, granite cleaning of paint and pigments.

4, strong granite oil absorption, try to prevent oil pollution.
5, the attention slip.
6, daily Crystal harden (March-June)
7, regular water and oil conservation treatment (2-3/)
