Hi
I am a traditional window cleaner but have recently purcased a wfp. I have a block of flats (up to 3/4storey) to clean. They have not been cleaned for some time and the PVC frames and sills are green! What type of bush should I use? Should I use a different brush to clean the frames/sills first? What type? Should I then change to a different brush to clean the windows?
Thanks in advance
Matt
