just booked another one off clean in for wednesday but im trying to perfect the way i do one off cleans i want the best results in the quickest way possible.
plus the window frames are aluminum with the black rubber seals can these windows be a problem for wfp

im thinking about blasting the frames with wfp then trad for the windows so that i know their is no paint or sealant on the windows plus i would leave the job without worrying about spotting ect.
how do you do your one of window cleaning jobs
