What Is Pure Water Window Cleaning?

If you’ve ever washed a window to find that once it dries, it’s covered in smears and white spots, this is because tap water contains minerals such as phosphates, nitrates, potassium and chloride. Pure water window cleaning is a solution for that.

In window cleaning terminology, pure water refers to ordinary tap water that has been through a filtration and purification process, which removes all of its natural minerals. This process makes the water much more suitable for window cleaning for several reasons that we’ll explore in this article.

After purification, the water now has all of its ions removed that were derived from the natural environment, the pipes and other sources. This now pure water is also known as deionised or demineralised water and no longer contains mineral ions such as those mentioned earlier, plus clothes including sodium (Na), calcium (Ca), copper (Cu) and iron (Fe).

This pure water is then used in the window cleaning process.

Pure Water Window Cleaning Explained

Once the water has been purified, it is ready to be used to clean your windows.

Pure water window cleaning works by feeding purified water up through a pole (which can reach windows up to five storeys high) to a purpose-designed brush. The dirt and grime on the glass, frame and surrounds is scrubbed, or agitated, which loosens it. One of the useful properties of pure water for window cleaning is that it’s great at attracting dirt.

The grime is then rinsed away using the pure water. This is a key part of the process – it  needs to be very thoroughly rinsed, as the pure water previously used to scrub will have attracted the dirt, which means it is no longer pure. Only pure water can be left behind to ensure a superb finish. Once rinsed, starting at the top and moving down, the windows are left to dry naturally (there is no need to rinse as no detergents or chemicals are used).

Once the water has dried, the purification process means it doesn’t leave any residue on the glass, and dries to a beautiful sparkling finish. In addition, the glass will stay clean for longer as the lack of residue means dirt, dust and pollution has nothing to bind with. Surprisingly, using detergents can actually mean your windows get grimy again more quickly as dirt is actually attracted to the residue left behind from the cleaning agents. This is one of the reasons we recommend pure water window cleaning as a superb solution.

Using pure water means that there is no need to include a squeegee as part of the window cleaning process. As long as the windows have been scrubbed and rinsed thoroughly they can be left wet so they dry naturally.

If your windows have been previously cleaned with water and detergent, it may take two or three cleans using the pure water method to remove the build up of a thin but stubborn film of detergent residue. Two or three cleans using pure water will remove this residue for good, leaving you with windows that stay cleaner for longer, with nothing left for the dirt to bind to as easily.
