Pure water systems (like the Reach & Wash system for example) were originally developed for commercial window cleaners to overcome restrictive Health & Safety rules relating to ladders but they also allow windows to be cleaned much faster than with a squeegee because the windows are left to dry naturally.
Normal tap water contains many minerals and when used to clean windows it is these impurities that are left on the glass when the windows dry, causing a less than satisfactory finish unless the windows are squeegeed off. However, once de-mineralised, pure water left on glass dries clear.
De-mineralised water possesses a strong desire to return to an impure state, therefore when used for cleaning, pure water actively absorbs all chemicals and minerals it comes across, making it an environmentally friendly cleaning solution.
When applied using a waterfed pole, the cleaning technique is simple, safe and efficient, suitable for reaching previously innaccessible areas, cleaning windows, frames paintwork, conservatories, vehicles and much more.
