To many, window cleaning is associated with the traditional image of the window cleaner using his bucket of soapy water, cloth and squeegee to clean windows and if the windows are over one storey high, to use a ladder.
However, this may be ok at ground level and first floor, but any thing higher than that is not a good idea as it puts the window cleaner at risk of accidents, and strict Health & Safety regulations means that cleaning companies would have to comply with this when employing window cleaners.
Therefore, the best method for higher windows is not the ladder but the ‘Reach & Wash’ pole system where the windows are cleaned from the safety of the ground. Pure Ionised water is pumped up through a long telescopic pole and a soft bristled brush is used to scrub the dirt off the glass, while jets of pure water are used to rinse the window. The ionised pure water, as it has no impurities, dries to a spot-free finish leaving no marks behind.
There are some limits to the effectiveness of this method; for example, if the windows have not been cleaned for a very long time and are in a really filthy state, it will take a few cleaning sessions before all the dirt is completely removed, whereas a window cleaner with a soapy bucket and squeeqee could get it cleaned in one session. However, though the latter may appear be more effective, there is absolutely nothing that should compromise the safety of the window cleaner, so the former i.e. Reach & Wash pole method is always going to be the best way to get those windows cleaned, even if it means doing it a few times initially to get all the dirt removed.
