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. Click this link to an article explaining water purification. 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.
