At the beginning of last month, Minister Zhang, an old local customer in Guangzhou, called me. Minister Zhang is the head of the logistics department of an Internet high-tech company. One of his daily tasks is responsible for the normal operation of their company's network center. Recently, he discovered that although the door sweep brush type in the network center has been covered with dust, it has actually played a good role in sealing and preventing dust. Out of the idea of energy saving and environmental protection, he wanted to clean and reinstall the current brushes, but he didn't know the correct method, so I called me to solve this problem for him.

After understanding Minister Zhang’s meaning, I taught him about the cleaning methods of this batch of door sweep brush types: 1. Never clean the door sweep brush type against the hair; 2. Brush the door sweep brush type after cleaning Hang up and let the bristles face down to dry; 3. After the door sweep brush type is cleaned, let the water drain, but remember not to twist the bristles, otherwise it will damage the bristles of the door sweep brush type, and the structure of the bristles will become loose. Hair removal. 4. It should be air-dried naturally, not with a hair dryer, let alone drying in the sun, otherwise the material of the door sweep brush type bristles may be damaged.

After listening to my advice, Minister Zhang went back and carried out a scientific and effective cleaning of this batch of door sweep brush types according to the method I taught him, and the brush performance continued to be good. Due to Minister Zhang's effective deeds, he was also praised by the company's leaders.
