Priced up a in and out clean this morning. All looked ok till I walked in main bedroom. It has two floor to ceiling doors four feet wide, one opens the other dosnt. As there is no balcony outside and the door opens out. The builders have put the glass screen on the inside. Only got 6inch gap between screen and door. Lady won'ts door and screen cleaned. WHAT do i need to get to this.? are the pure water interior kits any good. Would one get in this gap?
