I had one today who after I cleaned her windows for the first time WFP said she spoke to her Dad about the system. Apparently, he reckons theres no other way to clean windows
clearly enthused by his appreciation of the new-fangled system her window cleaner had invested his money in she made me promise Id do the wooden framed conservatory with it which I had prefered to do trad last time. Ho hum, nice people do exist (they have nice fathers too
)
