Therefore, it is preferable to frequently clean nthe windows installed on the walls of a building. n"However, the outer side of the window is more difficult to clean than the inner side, and particularly, as nhigher buildings are increasingly constructed, cleaning the outer side of the windows may involve great nrisks."
