exterior window cleaning
Pure water window cleaning involves tap water that has been stripped of naturally occurring minerals. The minerals in the water are measured by using a Total Dissolved Solids meter (TDS) by our technician to ensure that all of the minerals are removed before cleaning begins. Water used in this kind of cleaning operation is normally infiltrated reverse osmosis (RO), mixed-bed deionization (DI) or a combination of the 2 procedures. Pure water will greatly improve the cleansing result as pure water does not include any ions, hence, it is an extremely efficient rinse agent which leaves spot free results after evaporation. This pure water provides an outstanding choice for the activation, suspension and ultimate release of soils from surfaces and leaves very little chance of re-introducing soils on surfaces for longer periods of time. Free of any detergent(s), which oftentimes leave behind a microscopic film that allows dirt to stick to the surface, leading to faster re-soiling, the Pure Water cleaning process proves to be a greener and more economical choice for everyone involved. As there is no residue or static left after pure water cleansing, most surfaces cleaned with pure water methods remain cleaner for longer time periods.
The pure water runs through a telescopic fed pole, goes out to the soft bristle brush, and onto the window surface. The dirt is agitated by the scrubbing action of the brush and the dirt is then suspended in the water, all set to be rinsed away by the consistent stream of pure water. The efficiency and safety of this process is not easily matched by any other methods. There are poles available that surpass 40 feet of reach. This typically leads to improved security for operators, as ladders are no longer necessary in many instances and dangerous climbs up are no longer needed.
