Granite silicon spot: The stone surface is agglomerate and point-like, with brushing marks, thick color, bright, dripping water in the contaminated part of the water droplets, not dispersed, is the result of oxidation of the water-repellent agent after the concentration of the stone area. Silicone spot has strong water repellency, cleaning is more difficult than other stains. It can be wetted by KVD-05 for 24 hours. It can be infiltrated into the interior of the stone and completely reduced. If the ventilation condition is good, it can also be heated and wet. Apply to speed up the cleaning process. Granite water spot: On the stone surface, cement contaminants spread from the joints (cracks) of the stone to the surroundings. Matte and stains change from dry to wet with the weather. The dripping water spreads on the contaminated parts and the stone surface is deepened. Because the stone is not well protected, the cement mineral at the bottom of the stone dissolves through the water and the surface of the stone is blackened. It can be removed by KVD-06 wet dressing for 12 hours. If it is conditional, it can be wet for a long time and the effect is better. Stone degreaser: Cleaning marble macular rust spots are mineral oil and animal and vegetable oil dripping on the stone surface, which is clustered or spotted, and the color is obviously deep and shallow. Compared with silicon spots, there is no silicon spot bright, no, the oil stains with paper and sticks with grease. Can be removed with KVD-08. If it is mixed with black smoke from motor vehicles, it can be used as a silicon spot cleaning agent, and the wet application method is better. Marble, sandstone water spot yellow spot: Cleaning and removing the marble sand slab, because the cement material adhered to the bottom of the stone is spread on the stone surface ------- water stain black stain and alkali salt yellow stain, can be removed by KVD-08 wet dressing method or warm rub method. Note: Not for granite or ceramic tiles. Granite macula, rust spots: Can be removed with KVD-09. Marble yellow spots, rust spots: KVD-11 heating and wet coating method can be used to speed up the cleaning. Marble is mainly calcium carbonate and is susceptible to chemical attack. Therefore, the rust remover used is relatively mild and has certain limitations. The density of marble is higher than that of granite, and after surface polishing, the agent is not easy to enter the interior of the stone, and the effect is slow. The heating and wetting method should be adopted to make the stone voids expand, and the rust spots alternately loosen and react with the cleaning agent to restore quickly, which can be achieved with half the effort. Marble water spot cleaning agents may be affected by the limitations of the drug, and some stone surfaces may be affected. Please consider them. If necessary, it can be polished after cleaning.
