Our Window Cleaning Process
External work is carried out using a high-reach WFP system (water fed pole), whilst the internal work via traditional squeegee method.
- This work is done from the ground hence it is safer, less intrusive, environmentally friendly and faster than traditional methods.
- The WFP system basically uses tap water which undergoes a filtration process where pure water is produced and then is pumped through hoses and telescopic poles, directly onto the windows and frames.
- A soft bristled brush is used to agitate dust particles, which are then rinsed away with the pure water - no chemicals or detergents are used - just pure water.
- The cleaned windows will be left wet which seems unusual but be assured, once the water has dried, you will be left with sparkling windows with no spots or streaks.
- You will likely notice that the windows stay cleaner for longer. This is because there is no sticky soap residue left on the window. Usually rainfall would mix with this soap residue and form little spots on the windows
Generally, tap water contains dissolved solids which in technical terms is defined as TDS (Total Dissolved Solids) which is tested with a meter, the normal reading is between 40 and 300 parts per million. The higher the reading the harder and dirtier the water.
The Water Purification process »
- The tap water goes through a filtration process which is first achieved by
- Reverse osmosis (passing water through a membrane at pressure) - where the bulk of the impurities are filtered out, and then by
- De-ionization using a resin
- This purified water is pumped from a tank in our vehicle through a hose to a special lightweight pole and is applied to the windows and frames, firstly by brushing and then by rinsing
- The impurities on the windows or frames are suspended in the water and then rinsed off the surface, leaving the surface free of any mineral deposit
- The windows are left to dry and will have no spots or streaks as there are no chemicals on the surface
