There are several errors that can occur during Windows cleaning. Without any skilled assistance, cleaning the windows on your own is a rather boring option. I have personally tried to do it on my own several times. Even if I do a better job with each attempt. My cleaning at the end of the day is nothing compared to what could be pulled off by the window cleaners in such a short time. Throughout the year, Sydney has a sunny climate. When I am washing my curtains, there are more streaks than I can imagine.
