How pure water cleaning works.
The water we have in our taps is filtered to meet national water quality standards. This water is safe to drink, but still retains a level of of mineral content, when this water is applied to a surface and allowed to dry ,it is these minerals that are left behind to cause spotting and watermarks, they are too heavy to evaporate.
However if we first remove these mineral deposits and then apply Hot Pure Water to a surface, the water evaporates leaving no smears spotting or watermarks.
Pure water is rarely found in nature due to it's ability to absorb minerals and contaminates from it's surrounding environment, when the water is ultra pure ,this absorption rate is significantly increased, easily coping with the dust and dirt found on glazing, we use this pure water, applied with a soft bristle brush to a blemished surface, the pure water then absorbs the dirt and dust contaminates, the surface is rinsed, again using pure water and allowed to dry naturally to a spot and smear free finish.
The pure water cleaning process.
The use of pure water is arguably the most significant change to the window cleaning industry has ever seen.
On the first clean your operator will concentrate on your frames, His or her aim will be to remove as much dirt trapped in the seals of the UPVC as possible. You will notice a vast improvement to the overall look of your windows by the time this is done. However it is not unusual for the pure water to keep absorbing the dirt and after the window cleaner has left. if this is the case you will notice spotting on the glazing after the water has evaporated, DONT PANIC, this is normal. If your UPVC has seen a number of winters, your seals will have accumalated quite a lot of trapped dirt and dust. In some cases this process maybe repeated on the second clean once again depending on the age or location (main road) of your window frames.
By the third clean your glazing will be perfect, you will notice it will take longer for your glass to get dirty, this system has been tried and tested on Big Ben, BT Tower and the London Eye.
