Not posted for 120 days who cares,all you need is a good platform ladder to work off ,very good cleaning solution, that will do all the work for you,rinse off solids with low pressure on m/c,dip pole and soft brush in solution and wash away,might have to go over more than once,use machine to rinse off soap,left nice-n-white and shiny like the day fitted. My customers always say,my window cleaners never got them that clean before ,and this tells me something,stick to windows and leave the frames to get dirty as usual.
