There are usually two reasons can lead to granite rust spots, one, the rust water is the result of appearing rust. For example, granite surface suffered rain water flowing down from advertising aircraft; the other is the iron compounds come out oxidation and spread out when granite violated by water. Meanwhile, the granite rust spots should be promptly cleared for water treatment, because too much water marks, but also make stone contamination.

Second, cleaning and maintenance of granite stains Note:

1, acid and alkali granite is better than marble, so cleaning can be weakly acidic cleaners.

2, granite harder than marble, abrasion resistance is better.

3, dense granite material, absorbent, easy to place in the patchwork of stone formation water spots, and difficult to dry, it is difficult to eradicate, so cleaning and maintenance time, minimize the water, even if the water should quickly drain.

4, granite and strong oil absorption, as far as possible to prevent oil pollution.

5, pay attention to slip.

6, daily crystal hardening treatment (3-6 months / time)

7, regular water, oil conservation treatment (2-3 years / time)
