de-mineralising water window cleaning  
Chemistry in action  

The water treatment system utilises Reverse Osmosis and mixed bed De-mineralising Resin to produce 100% pure, laboratory grade water.
The nature of de-mineralised water is to strive to return to its natural impure state by actively absorbing all dirt, chemicals and minerals it comes across.
When used for Window Cleaning, provided the correct technique has been used the final rinse water dries to a perfect finish. With continued use the window isn't just clean, its left totally sterile. As no chemicals or detergents are used, the process is environmentally friendly.

Tap water isn't just hydrogen and oxygen, but in fact contains many other chemical elements, such as calcium, chlorine, iron and copper.
If you wash windows with untreated tap water and leave it to dry, once the hydrogen and oxygen have evaporated, these chemicals and mineral residues are left on the glass leaving streaks and other water marks.

water filtration window cleaning  
4 stage process
Our 4 stage filtration system removes all chemical and mineral content from the water. Because there is nothing in the water, when it evaporates it leaves nothing behind, except sparkling glass.
1 Commercial water softener removes Calcium.
2 Carbon filter removes harmful Chlorine.
3 two 800 gpd RO units filter water to produce 95-98% pure water stored = in holding tank. (GPD = Gallons per Day)
4 Mixed bed resin De-ionisation tank polishes water from holding tank at point of use to deliver 100% pure water to the water fed pole.
The precedent has been set by the Replacement Window Industry, where glass used to produce double glazed sealed units is washed and rinsed using de-mineralised water prior to assembly. This is the reason that sealed units will remain optically perfect for many years, until the seal is broken.
