COMMERCIAL AND DOMESTIC WINDOW CLEANING TECHNIQUES.
Water & squeegee Commercial and Domestic Window Cleaning
Water and Squeegee are essential for internal window cleaning for both commercial and domestic properties. Generally, washing up liquid that can be purchased in any Bracknell or Ascot supermarket are added to water, and a device such as a Lambswool applicator is used to scrub glass. A squeegee is then used to remove the dirt and water mixture from the glass.
Chemicals added to the solution range from dish soap and glass cleaner to Trisodium Phosphate and etching salt. In sub-zero temperatures, anti-freezing chemicals should be added to the solution to prevent it from crystallizing glass before it is removed with the squeegee.
Many residential window cleaners still only use this “old school” technique as they are well practiced and find it easy, however it requires considerable ladder work. Needless to say ladder work is dangerous especially when it comes to second and third story properties in Bracknell, Ascot, Surrey and Berkshire. Many window cleaners across Surrey and Berkshire have fallen off ladders at some point in their carrier with some incidents being lethal. For this reason we highly recommend all window cleaners and customers to consider water-fed poles as they are far safer and purified water leaves the glass spotless therefore is ideal both domestic and commercial window cleaning.
Water-fed Pole Commercial and Domestic Window Cleaning
Commercial and Domestic window cleaners use a variety of telescopic poles, fitted at the upper end with a brush and water jets, fed either from vehicle mounted tanks of purified water or fed by pure-water trolley or backpack. The commercial purified window cleaning water is filtered by either a two-stage or three-stage filtration process, involving a carbon filter, and two de-ionization filters, or a carbon filter, a reverse osmosis membrane filter, and a de-ionization resin filter.

The window cleaning brush is used to agitate the debris off the window, while spraying water, and then the brush is lifted a few inches from the glass to rinse the glass with the pure water jets. Fan jets are used for hydrophobic glass, and “pencil” jets are used for hydrophilic glass. The de-ionized water is lacking in ions, so it will pull solids off the glass and dissolve the solids into the water, aiding in the cleaning process. Because there are no solids dissolved in the water, the windows dry clear without water spots. Water-fed poles vary in length. The longest poles are about 70 feet, and can reach up to six storeys. Commercial and domestic Water-fed cleaning is also referred to as pure water cleaning. It is common in the UK and most professional commercial and domestic window cleaners in Bracknell, Ascot, Berkshire and Surrey will use water-fed poles to clean windows.
This article will explain what purified water is and why it is used by commercial and domestic window cleaners in Bracknell, Ascot, Berkshire and Surrey.
Purified water is used by commercial and domestic window cleaners in Bracknell, Ascot Berkshire and Surrey and is water that has been mechanically filtered or processed to remove impurities and make it suitable for use in commercial and domestic window cleaning for customers in Bracknell, Ascot Berkshire and Surrey. Distillation has been the most common form of purified water for commercial and domestic window cleaning, but, in recent years, water is more often purified by various processes including deionization, reverse osmosis, carbon filtering, microfiltration.
Many commercial and domestic window cleaners in Bracknell, Ascot Berkshire and Surrey use Combinations of a number of these processes to produce water of such high purity that its trace contaminants are measured in parts per million (ppm). Purified water has many uses, largely in the production of medications, in science and engineering laboratories and industries, and is produced in a range of purities.
Distilled water is produced by a process of distillation and has an electrical conductivity. Distillation involves boiling the water and then condensing the vapour into a clean container, leaving solid contaminants behind. Distillation produces very pure water. A white or yellowish mineral scale is left in the distillation apparatus, which requires regular cleaning. Distilled water, like all purified water, must be stored in a sterilized container to guarantee the absence of bacteria. More economical alternatives will be used by commercial window cleaners, such as deionised water these are used in place of distilled water. Albeit interesting to know the distillation process commercial and domestic window cleaners in Bracknell, Ascot Berkshire and Surrey will use more suitable and economic methods to produce purified water.
Most commercial window cleaners in Berkshire and Surrey will Deionize their water. Deionized water often confused with demineralized water, is water that has had almost all of its mineral ions removed, such as cations like sodium, calcium, iron, and copper, and anions such aschloride and sulphate. Deionization is a chemical process used by commercial window cleaners that utilises specially manufactured ion-exchange resins, which exchange hydrogen and hydroxide ions for dissolved minerals, and then recombine to form that can be used to clean windows. Because most non-particulate water impurities are dissolved salts, deionization produces a high purity water that is generally similar to distilled water, and this process is quick and without scale build-up therefore most commercial and certainly some domestic window cleaners will have a deionising vessel as part of their kit.
Reverse osmosis (RO) is a water purification technology used by commercial and domestic window cleaners in Bracknell, Ascot Berkshire and Surrey. Reverse osmosis can remove a multitude of molecules and ions from solutions, including bacteria. This process is used for commercial and domestic window cleaning as well as in other industrial processes by businesses in Berkshire and Surrey. The result is that the solute is retained on the pressurized side of the membrane and the pure solvent is allowed to pass to the other side. To be “selective”, this membrane should not allow large molecules or ions through the pores but should allow smaller components of the solution (such as the solvent) to pass freely.
The reason why commercial and domestic window cleaners use purified water is because when it dries off the glass it does not leave and smears or water marks
