Why don't you have a quick google before making stupid comments?
How would you clean a house that's got bars across windows any ideas please ?
I've just picked up a huge complex and some of the 3rd and 2nd story French doors have bars on them, but unfortunately the bars are so close together the brush will definatly not fit between. So the manager is happy for me to pole above the bars and just rinse, or spray water on the bottom of the glass through the bars. No ladders allowed .
