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.
In manual applications, the cleaner wipes dirt off the panes using water that contains cleaning chemicals. Dirt is removed through scrubbing using hands. Removed dirt and water mixture are sluiced from the panes by use of different types of squeegees. Manual cleaning can be applied on all types of windows if the cleaner can access them.
The reason for the invention of water poles was so that cleaners can effectively clean windows with the range of 3-70 feet from the ground. It involves installing brushes and water jets onto telescopic poles. Water supplied through the jets are deionized and come from sources like domestic, commercial, and vehicle-borne water outlets. The concentration of total dissolved solids in the water is below 5 ppm. The longest pole is 70 feet although shorter lengths are available.
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.
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.
