Using our 4-stage Pure Water Reverse Osmosis and Deionizing Filtration System, we are able to provide a spot free ultra pure window cleaning. The technology for these systems is not new, it has simply become more compatible to the needs of window cleaners. With the use of the WFP (water-fed pole) we are able to reach upwards of 60 ft to service even low rise office buildings. We believe this technology offers benefits to our clients and is actually a more effective method of cleaning windows. Pro Green Window Cleaning Services offers its 5-stage Pure Water Reverse Osmosis and Deionizing Filtration System to homeowners and businesses throughout Surrey & Staffordshire. Benefits of Pure Water Technology No soaps or chemicals are used in this process. Surprisingly you will notice that your windows will stay clean longer because the surface of the glass will not have the sticky soap residue which causes dirt particles to adhere to the glass. Using a boar bristle brush we agitate the entire window casement, sill and glass surface removing dirt particles, followed by a spot free ultra pure rinse. Allowing the glass surface to dry spot free is critical to maintaining the desired results. You should expect to see windows left wet, don't worry this is normal. It may be a little disconcerting at first, since this is not what you have been used to, but please be assured that the windows will dry naturally, and once dry you will no doubt be impressed with the results. By cleaning window casements, frames, sills, and glass surfaces with this method you should expect better cleaning results for a prolonged period of time
