Window cleaner climbing out of a scaffold in Shanghai This method is still used at the Empire State Building in New York City. Permanent suspended platforms are called building maintenance units (BMU), or, in Europe, gondolas.ĭirect access to a window obtained by egress from that window. Both having their own unique governing codes and regulations. These can be either temporary or permanent. Platforms may be fitted to high rise buildings or skyscrapers, or assembled from components to suit architecture and nature of work being performed.

These are always temporarily installed for the purpose of access. Often referred to as "rope descent systems" (RDS), these are typically anchored to a roof structure, counterweight configuration, or connecting points designed for the purpose. Boatswain's chair (bosun's chair) - A single-person seat designed for controlled descent of rope.Aerial work platforms are elevated platforms that workers can stand on, such as a scissor lift, or cherry picker.Rope Access - using abseiling equipment, consisting of a safety harnesses and rope connections to lower individual window cleaners to positions where they are enabled to clean.They raise and lower the worker either by hand or with a motor. Suspended platform or cradle - Unlike supported scaffolding, these are not fixed to a lower surface or the ground, but rather are suspended by wire rope from above.Supported scaffolding - A temporary platform workers can stand on that is rests on a surface below, rather than hanging from above like suspended scaffolding.If a window is not easily accessible using one type of equipment then it is advisable to combine different tools to be able to clean it properly. Methods of access and equipment related to both access and cleaning vary nationally and regionally. Window cleaning platform, or suspended scaffold, also known as a swing stage It is common in the UK and becoming common in the US. Water-fed cleaning is also referred to as pure water cleaning. The longest poles are about 70 feet, and can reach up to six storeys.

Because there are no solids dissolved in the water, the windows dry clear without water spots. 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. Fan jets are used for hydrophobic glass, and "pencil" jets are used for hydrophilic glass. The 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. The amount of spotting would depend entirely on what mineral composition is the water. The reason for this is that if using above zero ppm water, reach and wash water-fed pole window cleaners cannot claim to be purified water window cleaners and subsequently, a reading above 0 ppm could lead to spotting on the glass. The filtered water should contain a TDS (total dissolved solids) of 0 ppm (parts per million) when being used on windows. The 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. Water-fed poles - Any of a variety of types of telescopic poles, fitted at the upper end with a brush and water jets, fed either from vehicle-borne tanks of deionised water or by on-site production of deionised water using a domestic or commercial water outlet.In sub-freezing temperatures, anti-freezing chemicals are added to the solution to prevent it from crystallizing on the pane before it is sluiced off. Chemicals added to the solution range from dish soap and glass cleaner to Trisodium Phosphate and etching salt. A squeegee is then used to sluice the dirt and water mixture from the glass. Water and squeegee - Generally, chemicals are added to water, and a device such as a brush or cloth-covered handle is dipped into the resulting solution and used to scrub glass.Chamois and scrim - Chamois is used to loosen and remove dirt, followed by a buffing with scrim or cheesecloth.Window cleaning with a water-fed pole in Bath, England
