MODERN WINDOW CLEANING WITH DEIONIZED WATER Higher – Faster – Safer

When most people think of a window cleaning, they imagine a man scurrying up ladders and squeegeeing off soapy water from a bucket.

Standard Auckland water has about 90 parts per million of impurities. Our system reduces this to less than five parts per million.

However, like so many other industries, window cleaning has moved on.

These days, modern window cleaners use special waterfed pole systems and deionized water to clean windows safely from the ground. A soft bristled brush is used to scrub the dirt off the glass, while jets of very pure water rinse the window. The pure water not only cleans the dirt off more efficiently, it also dries to a spot-free finish as it has no impurities.

The science – how does pure water clean glass without chemicals?

Tap water contains many types of minerals such as calcium, magnesium, potassium, sodium etc. These are called Total Dissolved Solids or TDS and are generally measured in hundreds of parts per million. If you wash a window with tap water or leave your car out in the rain, the TDS elements don’t evaporate with the water but remain as residue causing “spotting”.So in other words,“water spots” are caused by the minerals left behind when “dirty” water evaporates; de-ionization removes these minerals so there is nothing left to cause spotting.

Deionized water uses a double action to clean glass without chemicals as explained below:

1. Pure water cleans glass a lot like soap cleans dirty hands. Soap molecules cling to the dirt on your hands to make it easier to wash away.In the same way, pure water wants to return to its “impure state” and so clings to the dirt on the glass making it significantly easier to clean.

2. Once the dirt is washed away, all that is left is pure water with little or no TDS elements. As the water evaporates no residue is left behind leaving sparkling clear glass.

So the power of pure water means that simply rinsing the glass after scrubbing leaves an excellent streak and spot free glass surface. No chemicals, no detergents, all that is used is pure, deionized water.

Our carbon fibre poles can reach up to seven storeys!

The advantages of using deionized water

By using pure water Got Dirty Windows will give you the following benefits:

• Environmentally friendly – no detergents or any type of chemical is used, just pure water.

• Efficient – cleaning with irrigated poles is up to 50% faster than using ladders. This minimises interruption to staff or the general public.

• Thorough cleaning – using a brush means window frames and surrounds are also cleaned as part of the process.

• Greater reach – areas that are very difficult to get to because of physical constraints can now be cleaned.

• Safety – up to seven floors can be reached without the need of ladders, cherry pickers or abseiling. This also saves considerable money.  Abseiling requires at least three people and takes about two hours just to prepare and ensure safety.  Using a pole means the job is done with one person and you start within five minutes of coming onsite.

Got Dirty Windows use several poles which range in size from three to twenty metres.

While our largest poles are very expensive, they are constructed with cutting edge, carbon fibre technology. This means the 20 metre pole weighs less than three kilograms, but is so incredibly strong you can drive a car over it without causing damage.

The brush has hog hair rather than monofilament nylon. This has the advantage of increased scrubbing power as the bristles tend to lie flatter on the glass and get into the corners of sills better. The hog hair brush is further assisted by a goose neck connector to allow easy reach of deep window sills.
