When pure water is used for window cleaning the pure water strives to return to its natural impure state and in doing so captures any impurities on the windows. The glass is given a final rinse with the water fed poles to leave the glass totally sterile. The windows dry spotless without the need to wipe away contaminates.

The replacement window industry use pure water when producing double glazed sealed units. By washing and rinsing the glass using de-mineralized water prior to assembly the sealed units will remain optically perfect for many years, until the seal is damaged. We use the same system to wash the outside of the windows to ensure a smear free, spotless, sterile clean.
