What is Pure Water Window Cleaning?
The term Pure Water in window cleaning describes ordinary tap water that has been filtered through a purification system, to remove all the natural minerals. This water is often described as ‘deionised water’ due to the type of filtration used. The reason for this is that pure water dries to leave a completely crystal clear finish.
If you've ever thought 'Why do Window Cleaners not dry the windows?' Here's why; When applied to Window Cleaning, using pure water means that there is no need to squeegee the water from the window. Providing you have agitated (or scrubbed) the dirt and rinsed the window thoroughly to remove the dirt, you can leave it wet and it will dry completely clear!
Once water is purified, it is ready to clean with. However it’s not just a case of ‘splash & dash’, there is some know-how required. The first step is to agitate (scrub) the windows with a water-fed pole & brush designed specifically for the task. By scrubbing the windows you’re loosening any dirt or build up on the window, frame and surrounding plastics.
Rinsing the loosened dirt and debris is important, as anything except pure water left on the window will ruin the perfect finish. The deionised water will attract the dirt and minerals scrubbed from the window, creating a non-pure solution. This needs to then be rinsed thoroughly from the window, leaving only Pure Water left to dry clear in a matter of minutes (the same applies to sills and frames). Best practice is generally to begin at the top, and rinse down the window going left to right to ensure everything is removed.
