We use both traditional methods and pure water fed pole methods for cleaning. The WFP (Water Fed Pole) method gives better results as "NO" chemicals or detergents are used, so no residue is left on the glass for the dirt to stick too. The water used has been purified through a reverse osmosis filtering system and then put through a de-ionising resin to remove all the minerals etc., to give pure water
