F.A.Q

 

Can I work in the rain with a pure water system?

If we examine the water cycle, we learn that the water evaporates from the surface of lakes, rivers and the sea. Their mineral content is left behind when the water vaporises, which means that when the water condenses and forms clouds, the water is pure.

It is this pure water that falls as rain. The rain does not stay pure for long however, because as it falls through the atmosphere, the water molecules bind to and dissolve all the minerals it comes into contact with on its way to the ground.

While this water is no longer pure, it does have a relatively low mineral content. In the UK with our usual south westerly winds, the total dissolved solids reading of this water is around 14 TDS, with the limit for spot free drying being 9 TDS or lower. (Some tap supplies will reach 500+ TDS)

When cleaning windows with pure water, pure water is left to dry naturally on the glazing, when the rain comes into contact with this water, it serves to dilute the rain water. If an equal amount of rain water falls on the freshly washed glazing, the TDS reading of that water will then read 7 TDS within the range of spot free cleaning.

In short then, you can clean windows with pure water in all but the most torrential rain with most satisfactory results.

Many clients may well be sceptical at first, as using chemical cleaners leave a residue that becomes sticky and actually attracts dirt and that is what they will be used to. However once they have seen the results for themselves, most clients will have no problem with you calling when the weather is far from ideal.


Can pure water systems clean heavy soiled glazing?

Pure water is known in the scientific world as the universal solvent, virtually all substances known to man will dissolve in pure water given enough time.

Pure water cleans using a process called; hydrogen bonding, in which the hydrogen atoms bond to contaminants and dissect the contaminant molecule at the atomic level.

The grater the amount of contaminants, the more pure water will be required to remove it, but even the heaviest deposits can be removed effectively with a little more time invested during the clean.

Heavily soiled gazing covered with such deposits as moss, thick dirt and birds mess is very effectively removed when using pure water. If the system you use is heated, this cleaning process is accelerated.

As a general rule, anything that can be removed with traditional window cleaning methods can also be removed using pure water.


Is it safe?
Yes. Because the operators work from the safety of the ground and no ladders or other equipment are used.

 

Are the poles heavy and how do you control it so high?
The poles are made from high quality carbon fibre which is a very light but extremely strong material. As it is so strong and durable we can easily control the poles without too much friction or bend. When working on heights in excess of 40 feet we always work in pairs with one person checking the terrain.

 

What method do you use to clean the windows?
On top of the pole is a nylon brush head with a small channel that jets out a constant supply of pure water. First we clean the frames and then the glass by moving the brush head (which is constantly wet) over them. We then rinse the windows and frames and leave to dry to a spot free finish.

 

How can pure water not leave any marks or droplets?
Unlike bottled water, rain or tap water which contains mineral deposits, pollution, calcium and chemicals our water is stripped of every element and is pure in every sense. We do this by using a technique called reverse osmosis which is a filtration process. The end result is 100% laboratory graded pure water. Because of its purity, quite simply nothing can deposit on the windows which are always left spot free.

 

How do you get a constant supply of water and where do you treat it?
Our water is treated on our premises using a 4 stage filtration process. When this process is completed we transfer the water into our specially adapted van which has 650 litre holding tanks. We then transport this water on site where it is pumped through the carbon fibre poles onto brush heads and ultimately onto the area to be cleaned.

 

Are any chemicals used during this filtration process?
No. All filters contain natural elements such as salt, resin beads and carbon sediment and are environmentally safe.

 

Can the water damage or stain my property or building?
No. More damage is caused from pollution in the rain or atmosphere.

 

Do you give free demonstrations and quotations?
Yes. We regularly give free, no obligation demonstrations and quotations. All demonstrations are carried out by normal members of staff, not sales representatives.
