How does pure water window cleaning work?

When pure water is used for window cleaning the impurities on the glass are held in the water, as the pure water strives to return to its impure state. The glass is then given a final rinse with the water-fed poles to leave the glass totally sterile.

Our window cleaning system produces a high level of pure water: from 1 to 30 ppm after the reverse osmosis purification stage (depending on the hardness of your water), and 0 ppm after the final stage which is the Dioniser.

Pure water (0 ppm) leaves your window neat and clean. With spot free water, your windows dry spotless without the need to wipe contaminates off. No detergent residue means that windows do not get dirty so quickly, so your windows stay cleaner for longer.
