I have just started cleaning the windows of this customer and she would like her conservatory roof cleaned every 6 months or so. I thought it would be fairly straight forward as it isn't all that bad. Anyway, I went to clean it today. The height of the conservatory caught me out as I could not really get an angle on the roof with the wfp. Is anybody able to give me any tips on how to clean this? I need to return back tomorrow or Monday to have another go, but made myself look a real tit today!
