In recent years, with the rapid development of the domestic construction industry, glass curtain walls have become an indispensable part of high-rise buildings. Under the combined effects of sunlight, air pollutants, dust and acid rain, water stains and dust will gradually appear after a period of accumulation. Once the pollution is formed, it will be difficult to clean, which will seriously affect the life and appearance of the building. If the curtain wall after installation is not cleaned and maintained regularly and comprehensively, the acid and alkali in the pollutants will penetrate into the surface of the building, corrode the surface and structure of the curtain wall, and cause irreparable losses. Therefore, Zhengzhou Xishui Cleaning Service Co., Ltd. suggests that in order to maintain the original appearance of the building and the neatness and beauty of the curtain wall, it should be cleaned and maintained regularly according to the degree of pollution of the curtain wall area.
