Before window cleaners used deionized water, they had to have direct access to the windows.  This meant that the employees were using ladders, ropes, and lifts to clean the windows. Using a water-fed pole, window cleaners clean up to four stories from the ground level.  This method is efficient and timely, thus saving you money and leaving your windows spotless.   

What is deionized water and how do you use it to clean windows?

Deionized water is also called demineralized water, DM water, DI water, or DIW.  Trace amounts of minerals like sodium & calcium are in tap water.  Through electrodionization, the dissolved minerals in regular tap water are removed.  We use a TDS meter (totally dissolved solids) to ensure that the filtered water is pure down to a measurement of 0 PPM (parts per million).  A brush is used to agitate the dirt from the glass and then it is rinsed completely with the deionized water.  When it the glass dries, it is completely spot and streak free.  This method is also effective at cleaning window frames and tracks.

So it’s just purified water that cleans the windows… no chemicals?

That’s right.  We often only use deionized water to clean the exterior part of your windows, absolutely no chemicals are used.  It’s just really, really pure H2O.  That means it’s safe for the environment, landscaping, pets, and people.
