If you have seen a window cleaner working from the ground with a long pole and wondered why there is no bucket of soapy water or squeegee at the top, you have probably seen a pure water window cleaning system in use. It is a practical method for cleaning exterior windows, particularly upper-floor glass that can be reached safely from the ground.
Window Cleaning Telford uses a purified water-fed pole system for residential exterior window cleaning. This guide explains what that means, how the process works and why the glass is normally left to dry naturally afterwards.
What is pure water window cleaning?
Pure water window cleaning uses water that has been treated to remove dissolved minerals and other impurities. Instead of applying ordinary tap water and then removing it from the glass with a squeegee, purified water is delivered through a water-fed pole to a brush at the window.
The brush is used to agitate dirt on the exterior surface. The window is then rinsed with purified water and allowed to dry naturally.
Why not simply use tap water?
Ordinary tap water contains dissolved minerals. When untreated water evaporates from a surface, those minerals can remain behind. A purified-water system is designed to reduce those dissolved solids before the water reaches the window.
This is why the final rinse is important. Once dirt has been loosened and rinsed away, the purified water remaining on the glass can be left to evaporate rather than being wiped off.
How does a water-fed pole clean a window?
The basic process is straightforward:
- Purified water travels up the pole. Water is pumped through a hose running to the brush head.
- The brush agitates the exterior surface. This helps loosen dirt from the glass and the areas being cleaned around it.
- The surface is rinsed. Purified water carries loosened contamination away.
- The window is left to dry naturally. There is normally no need to squeegee the final purified-water rinse from the glass.
Why can the windows look wet when the cleaner leaves?
A freshly cleaned window may still have water on it when the job is finished. That does not mean the clean is incomplete. With the pure-water method, natural drying is part of the process.
The important distinction is between clean purified rinse water and dirty water left on the glass. After the surface has been properly agitated and rinsed, the remaining purified water is intended to dry on its own.
What are the practical advantages of a water-fed pole?
- Many upper-floor exterior windows can be cleaned while the operator remains on the ground.
- The system can clean more than the centre of the pane because the brush can work around the exterior window area being serviced.
- The final rinse does not need to be removed with a hand-held squeegee.
- It provides a repeatable method that works well for regular exterior window-cleaning rounds.
Does pure water mean chemicals are needed?
Pure-water window cleaning is based on purified water, brushing and rinsing rather than relying on detergent for the standard cleaning process. The important work is mechanical agitation with the brush followed by a thorough purified-water rinse.
Is it suitable for regular residential window cleaning?
Yes, it is particularly useful for routine exterior cleaning where windows are maintained on a regular cycle. Window Cleaning Telford offers an approximately six-weekly residential round as well as one-off exterior cleans.
