For window cleaners, Reverse Osmosis water has multiple advantages that ease and speed up the work when compared to using ‘normal’ water.
The most important advantage is that RO-water is residue-free, meaning that the surface dries spot-free and no squeegee or sponge is needed. This saves valuable time for the window cleaners, as they only have to brush the window with a water-fed pole and rinse it by pulling back the brush. Because less actions are needed, cleaning a window may be done up to 50% faster! Also, the surface stays clean for a longer period of time. Because window washers work faster and the frequency of cleaning windows is lower when RO-water is used, the costs for window cleaning are reduced significantly.
Another advantage is that no chemicals or cleaning products are needed. The purer the water is, the more aggressive it gets. RO-water breaks the bond between the dirt and the window on ionic level, making it easy to rinse the dirt off, making this an environmental friendly way of cleaning as well. Also in high-rise construction, architects and contractors strive to work as environmental friendly as possible. Reverse Osmosis perfectly fits this trend.
You can imagine that the characteristics of RO-water are of great value, economically as well as environmentally, when a large surface needs to be cleaned regularly. Like the glass facade of a skyscraper for example.
