由于大樓位居要樞，相對地污染也特別嚴(yán)重。由于石材本身具有毛細(xì)孔及吸水性，空氣污染，灰塵加上空氣中的酸氣，汽機(jī)車的廢氣等，日積月累地附著于石材表面，當(dāng)下雨的時候，酸雨會加速這些污染對石材的侵蝕且吸附在石材的毛細(xì)孔內(nèi)，造成不易清洗的污斑，尤其對于火燒面的石材來說，這些污染形成的速度更快，且不容易清洗，僅使用市售的清洗劑根本無法去除這些污染;若是光面的石材，這些光澤很快就被侵蝕掉。
The building in the drive, relatively pollution is particularly serious. As the stone itself has pores and water, air pollution, dust and air in the acid gas and steam locomotive gas, accumulate over a long period of time attached on the surface of the stone. When it rains, acid rain will accelerate the pollution on the stone of erosion and adsorption in the stone of the pores of the, resulting in easy to clean stains, especially for the burning of the surface of the stone, the pollution formation speed faster, and it is not easy to clean, only using a commercially available cleaning agent cannot remove the pollution; if it is a smooth stone, the gloss soon is eroded away.

因此，要去除這些污染，可以使用客林 石材清洗劑，這類石材專用的清洗劑可以將滲入毛細(xì)孔內(nèi)的污染完全去除，且不會傷害石材。如果要防止石材再一次被污染的話，可于石材清洗干凈后，在石材表面干燥的情形下，再作一道防護(hù)處理的工作，這種滲透性的防護(hù)劑常用的有客林 墻體防水寶、石材保護(hù)劑，這兩種防護(hù)劑可以滲入石材內(nèi)部，形成一道防護(hù)層，具有防水、防污、防止泛堿、防銹斑、防油污、防風(fēng)化、防老化、耐酸堿、防茶漬、可樂、醬油等造成的污斑的效果，并能有效控制白華的產(chǎn)生，且不損及石材原有的透氣性，平常清洗工作只需用水擦拭即可達(dá)到效果，無需使用其他的清洗劑。
Therefore, to remove these pollution, you can use the guest Lin stone cleaning agent, this kind of stone special cleaning agent can penetrate into the capillary hole pollution completely removed, and will not damage the stone. If you want to prevent stone again polluted, in stone after cleaning, in the case of dry stone surface, then make a protective treatment work, the permeability of the protective agent used a Ke Lin Bao, waterproof wall stone protective agent, the two kinds of protective agent can penetrate into the interior of the stone. The formation of a protective layer, waterproof, anti fouling, prevent rust spots, efflorescence, anti oil, anti weathering, anti aging, anti acid and alkali resistant stains, tea, cola, soy sauce and so on cause effect, and can effectively control the Bai Hua, and does not damage the original stone and the permeability, the usual cleaning work only water wipe effect, without the use of other cleaning agent.
外墻污染的事前防護(hù)處理：一般來說，石材的外墻均有相當(dāng)之高度，一旦造成污染后再來清洗，施工極為不便。如果事前能做好防護(hù)處理的話，完工后便沒有污染上的問題，日常的清洗工作也只需用清水擦拭即可，而且施工前的防護(hù)處理成本較低、施工較容易，使用石材保護(hù)劑，這種的突破改善了以往防護(hù)處理費時費力的困擾，這種工法在國外已被廣泛應(yīng)用在石材工程上。
Protection treatment of external wall pollution: in general, the stone walls have a considerable height, once the pollution caused by cleaning, construction is very inconvenient. If the prior to do a good job in the door handle it. After the completion of no pollution problems, daily cleaning work is only needed water wipe, and before the construction of protective treatment cost is low, construction is easier, stone protective agent, the breakthrough to improve the previous protective treatment time-consuming problems, this method in foreign countries has been widely used in engineering stone.
