What is purified water window cleaning?
The difference between traditional and water-fed pole systems is often debated, and one of the most important factors is the water used.
The purified water Mr. Reach uses is de-ionised to the highest level possible, making it even purer than rain. We use a special total dissolved solids (TDS) or ‘impurities’ meter, which tells us how pure our water is.
Watch our video about how we check our water every morning.
All Mr. Reach window cleaning operatives use purified water-fed reach and wash system, as well as the traditional method where required for the best finish. Our operatives are proud of the fact that they use only the purified water, and will not work if the water is reading anything higher than ‘zero’ on the total dissolved solids meter.
The purified water is created using by feeding normal tap water into a reverse osmosis machine, which filters impurities out. The water is filtered through a special resin, which removes the impurities. The resins are regularly replaced to ensure only the purest water is produced.
Isn’t purified water just rain water?
We love educating people on window cleaning and the impact of rain – we have this conversation at least once a week with our customers.
Dirty windows are caused by dust, polluted air and more unavoidable solid dirt such as bird droppings, or mud splashes. If the rain falls on a dirty window, it will mix with the elements on the window, leaving a mess behind. If rain falls on a newly cleaned window, it will not show any marks.
That’s why rain doesn’t stop Mr. Reach from cleaning windows. The only time rain would ever stop Mr. Reach is if it was continuous after the last clean – as this would mean that the rain would clean the window, so we wouldn’t need to!
We consider the only downsides of cleaning windows in the rain are 1) wet uniform and 2) slippery surfaces, but the latter doesn’t really affect us because we keep ladder work to a minimum.
Ask your Mr. Reach operative to talk you through the water purification process or watch our video – it’s interesting stuff.
