Pure water - how does it clean?
Pure water is rarely found in nature this is because water has a natural tendency to absorb minerals. It is this mineral content and other impurities that leaves behind the spotting and watermarks you would notice if you washed with common tap water and left it to dry naturally.
When pure water is introduced to a dirty window, the water tries to revert back to it's impure state, in doing so it acts as a sponge absorbing the dirt from the window. After a thorough rinsing the windows are left to dry (approx 20 minutes). With no residue or impurities left behind - the results are a gleaming and streak-free finish.
Please note: If you have not had this type of service previously you will notice the difference immediately - however it takes approximately 2 - 3 regular cleans before achieving the superior results we expect. This is because we also remove the deep down dirt and grime from the frames, seals, joints, etc. which can leave behind some initial residue on the glass.
