Window Cleaning Nottingham
How We Clean Windows?
Pure water treatment – Secret to a streak-free shiny windows is the water. Our process is environmentally friendly.
We use pure water that has been specially processed without adding detergents or chemicals.
Pure de-ionized water is produced using a 4 stage treatment system of reverse osmosis and mixed bed dematerializing resin, as the water is pure it dries without leaving any marks.
We don’t use any harsh chemicals or ladders in the process, therefore there is no risk of damage to your property.
Water-Fed Pole – We use the latest Water Fed Pole technology, to keep your windows spotless all year round. Cleaning windows with Water Fed Pole is efficient, cost effective and safe.
How does pure water work in connection with water-fed window cleaning?
Pure water is pumped through the hose reel, via the telescopic pole and through the jets in the brush where it is sprayed onto the glass. When the brush contacts with the surface of the glass and frames, it lightly agitates the surface, loosening the dirt. Any dirt or dust particles are flushed away by the constant stream of water coming from the water-fed pole.
What would happen if normal tap water were used with a water-fed pole system?
Whilst normal tap water is fine for cleaning windows with a squeegee in traditional window cleaning, without the use of a squeegee it would result in the glass appearing milky white in color when it dries, and you will be able to write your name on the glass surface with your finger. This result in the glass is simply due to the mineral content of the water from the tap.
Water-fed window cleaning, on the other hand, differs from traditional window cleaning because instead of tap water, they use the equivalent of distilled water. That is – Water without any mineral content (or demineralised water) so that when pure water dries, it leaves the windows perfectly clean. Moreover, pure water does not exist naturally and will always absorb elements of the atmosphere as it returns to its natural state. As added to the window the dirt is immediately absorbed by clean water.
All water from out of a tap contains a number of minerals. The quantity differs from one area to another because of the variety of environment and ground rock strata that rainwater passes through before it reaches our rivers and ground-water storage reservoirs. If you were to buy bottled spring water from the supermarket and read the analysis label, you would notice that water contains minerals such as calcium, magnesium, chlorides, nitrates, sulfates, bicarbonates, sodium, potassium and silica etc…that are dissolved in the water.
When using water-fed pole systems, you need to make sure that the water you’re using is pure water. A TDS meter is therefore required to identify the total quantity of minerals that are dissolved in YOUR tap water. TDS stands for: – Totally Dissolved Solids.
This handheld TDS meter will give a three-digit reading. If you were to test the water at your tap, the meter would probably show a reading of between 035 parts per million (035 ppm) and 600 parts per million (600 ppm) This is ok for drinking, but it is not of any use at all for window cleaning! If you want to wash the glass and end up with perfectly clean windows, all the minerals need to be filtered or extracted from the water, giving a TDS reading of 000 ppm (indicating zero mineral content or total demineralisation). The area where you live or work will affect the TDS reading, and determine whether you are living a hard water area or a soft water area. For example, if you are living or working in a hard water area, then the overall cost of demineralising water will be more than it would if you were living in a soft water area.
