What is Pure Water?

So What Is Purified Water?

As a professional window cleaner, we use pure water, that is water that has been treated to remove any dissolved solids particles from the water. Tap water is full of these contaminants, which stop you from being able to wash with water alone without leaving, marks, spots and smears etc. Believe it or not, but water from the tap these days in not “Pure Water”, but is full of impurities. The level of these impurities vary from region to region, and here in East Sussex, our tap water if fairly good compared to many other parts of the country. In fact, bottled drinking water often has even more ” Total dissolved solids *than tap water commonly found in East Sussex. I process tap water, causing a de-ionisation process, which removes the dissolved solids. The resulting purified water give us 2 important benefits, with regard to cleaning windows:

  • The water is now much better at removing dirt from your windows
  • The water has no contaminants to leave any residue on your windows afterwards.

Normal household tap water contains sediments and minerals, it is these impurities that cause the spots and streak marks you see if its left to dry on the glass. To eliminate the chance of this happening all our water is put through our filtration system. This system is made up of a series of filters and resin which take out different contaminates at different stages of the process. The Process uses the following methods to purify the water. Osmosis, where water molecules pass through a semipermeable membrane under pressure removing particles. Deionisation, where all the ions are removed from the water, these ions include calcium, sodium, iron, copper which get into the water from the ground and even the pipework that delivers it to your tap.

Then finally we test our water with a particle counter, and if it meets our high standard we put it into our tank ready for a days Cleaning.

Its because we take this much care with our water that we know when we use it to clean your property it will evaporate leaving you with a spot free, streak free, lovely gleaming window.

Water Fed Pole / Pure Water Window Cleaning

When cleaning your windows, I use a specially designed ‘brush head’. This is no normal brush head, but has been specifically designed and made for the purpose of cleaning glass with pure water. This brush head goes on the end of a long pole. I then pump up pure water to the brush head, and through jets in the brush. Using this pure water and this special brush head, I can remove the dirt from your windows, frames and sills. The fibres in these brushes have a number of qualities, but those most important to you are:

  • They do not hold dirt in the brush fibres themselves, which aid the window cleaning process.
  • The brush fibres are kind to glass, and don’t mark your windows.

After the dirt has been removed, I rinse off the windows with more of this treated water. This leaves them very clean, and since the is no residue from detergent, cleaning product, contaminates in the water or anything else, your windows actually stay cleaner for longer! They stay cleaner, because there is nothing for the dirt to stick to – no residues, not even a micro fine layer since everything has been cleaned off using pure water and rinsed again just to make sure it’s clean, with pure de-ionised water.

The Windows Are Still Wet

Unlike traditional window cleaning methods, after I have finished cleaning your windows, I will leave your windows and frames wet. By leaving them to dry naturally, it stops the chances of introducing any contaminate, thus leaving them sparkling clean and they stay cleaner for longer!

 Kind To Your Garden & Paths

All that is left after I have been cleaning your windows is pure de-ionised water. This will do no harm to your plants or your paths etc. if any water runs on to your garden.

Other benefits of using the pure water fed pole system

Other benefits of using the water are being able to reach windows that are inaccessible to ladders, for example, high rise flats, offices, conservatories and solar panels, as well as unusually designed homes that require high access window cleaning.
