Window cleaning is also referred to as window washing. Commercial window cleaning has a long history and has undergone a lot of modifications over time to the point it is now. In modern days, the process has been automated a lot to the point where human labor is almost considered not necessary. The use of automatic robotic cleaners is on high rise in developed societies.
Previously, window washing was dominated by the use of manual methods, which involved using simple tools and hands. Back in the day, windows were not very high-rise like they are today and buildings usually had lesser numbers of windows. This changed over time and modern building styles set in, with windows increasing in number and being placed at high altitudes. Better washing products and methods had to be found through the invention of better ones.
Water containing dissolved detergents is used to wipe dust from panes in manual applications. Hands are used to scrub dirt off. Water mixture and scrubbed dirt are sluiced from panes using squeegees of various types. Provided the cleaner gains access to the pane, they can use manual methods to clean any kind of window.
The use of water-fed poles came into use to allow cleaners to access windows that were located at heights above 3 feet and less than 70 feet. A telescopic pole is mounted onto a brush and water jet. The water is usually deionized and may be fed from various sources including vehicle-borne water outlet, domestic water outlet or commercial water outlet. The water contains total dissolved solids to a concentration of less than 5 ppm. Poles vary in length with the longest measuring 70 feet.
Dirt on the surface is agitated as a constant supply of water is maintained. The pole usually has two jets. One jet supplies water that has cleaning chemicals and the other one supplies water that is pure. After all dirt has been agitated, the brush is lifted from the pane to apply pure water. The pure water removes all dirt without leaving any spots behind, which makes this method effective.
Better access methods have been invented for use at altitudes above seventy feet. Examples of those methods include supported scaffolding, cradle access, aerial work platforms, windowsill access, rope access, and use of ladders. The panes to be cleaned are accessed by the cleaners after being delivered by these access techniques. Not all methods suit all applications, although several applications can be suited by one method.
The use of a specific access method is usually reached after a thorough assessment of the site and building has been done. In some buildings more than one access method may be used simultaneously. Regulations require companies to select the safest method for use to avoid accidents, which used to be very common in this industry some years back.
This industry has been the target for environmental safety concerns for a long time now. There have been calls to invent and use products with minimum degradation effect to the environment. To that effect, eco-friendly products have been invented to help in conservation of the surroundings.
