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, manual methods that involved use of simple tools and hands dominated the process of window washing. The reason for this could be thought to be the presence of fewer, smaller, and low rising windows on buildings. However, over time, buildings started getting taller and windows rose to higher altitudes. Therefore methods of access as well as washing had to be changed. Invention of better methods had to be done to keep up with the changes.
When the process is done manually by the cleaner, water containing chemicals is used to wipe dirt from the glass. The cleaner has to use their hands to scrub the glass in order to remove dirt. Squeegees are commonly used to sluice the removed dirt and water mixture from the panes. This method is applicable on all kinds of windows provided the cleaner gains access to them.
Water-fed poles came into existence so that cleaners can be able to clean windows that are 3 feet above the ground and below 70 feet. A brush and water jets are mounted onto a telescopic pole. The jets supply deionized water from sources such as commercial, domestic, and vehicle-borne water outlets. The water contains a concentration of less than 5 ppm of total dissolved solids. The lengths of poles vary with 70 feet being the longest.
Dirt agitation is done while water is sprinkled constantly. Usually two jets exist are installed on the pole. One of the jets delivers pure water and the other jet delivers water mixed with cleaning detergents. Pure water is applied to the pane after dirt agitation has been complete. Pure water does a good job at removing dirt and never leaves any spots of dirt behind. This makes it an effective method.
At heights beyond 70 feet, other access methods have been invented. Such methods include ladders, supported scaffolding, aerial work platforms, cradle access, rope access, and windowsill access among others. All these methods deliver the cleaner to the pane they need to clean. Each method is suitable in specific situations although others can be applied in more than one situation.
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 also raised environmental safety concerns. Authorities required companies to employ techniques and products that limit environmental degradation. That has led to the invention of eco-friendly products with the intention of minimizing impact on the environment.
