Water, stored in a 400 litre tank mounted securely inside the window-cleaning van, is pumped to an inline filter and on through a de-ionising
bottle of resin. From here the newly purified water travels to a brush attached to the end of an
extending pole. Water's natural state is impure. The de-ionised (pure) water will absorb all contaminates (solids, minerals, dirt, dust etc) on the windows as it strives to return to its natural, impure state thereby leaving a smear and streak free finish. Pure water does not leave any residue unlike many other window-cleaning methods. Windows stay cleaner for longer periods - usually up to four weeks depending on the surrounding environment. |
