It is difficult to remove the dust from the glass. What kind of rag can be used to clean it?

I'm a hotel worker. According to my practical work experience, it's best to scrape with glass. Wipe the whole glass surface evenly with a rag dipped in detergent water (no one needs too much, otherwise the effect will be affected), and then scrape it hard with a glass scraper. Wipe the residual water on the glass with a rag after scraping, and then find a clean cotton cloth to scrape the residual water stains on the glass surface.

Note: 1, glass cleaning must follow the principle of from top to bottom, from inside to outside first.

Try not to scrape the glass in windy weather.
