At Crystal Clear we clean your windows with an advanced Water Fed Pole System. What we do is we connect a hose to your spicket and attach the hose to a DI tank. The DI tank than filters out all of the minerals commonly found in tap water creating pure water. This pure water than comes out of a water fed pole which is a pole with a brush on the end of it. The brush is used to remove all of the dust and dirt from the windows, and the pure water is used to rinse the windows and ensure that no streaks are left on the windows. Additionally to clean screens we use a high tech XERO screen cleaner which is a stand with a pair of brushes on each side that thoroughly cleans all aspects of the screen!
